EXAMPLES OF INVENTION EXECUTION

[0055] Example 1A A Minimal Jet Adapter, for Example for a Manually Operated Plastering Machine

[0056] The bracket 3 of the jet adapter 1 is installed in the holder 5 and has the diameter of 20 mm and the length of 600 mm and is fitted with one material supply opening 32 of the diameter of 8 mm and four jet openings 33 with the diameters of 10 mm situated on the opposite side of the bracket 3. The material supply opening 32 of the bracket 3 is connected to the feed hose 35 with the diameter of 8 mm. Three jet openings 33 are fitted with three jets 2 and one jet opening 33 is blinded by a plug of the jet opening 33. The jets 2 have the external diameters of 12 mm, follow the jet openings 33 and are installed in the plastic clamps 7 of the jets 2 secured by a screw keeping the jet 2 in its place, and are secured by the cases 6 of the jets 2 fixing the jets 2 pressed onto the jet openings 33. Each jet 2 has one longitudinally arranged through-going jet channel 22 with the diameter of 3 mm and two gas feeds 24 arranged in accordance with the rules of rotational symmetry, with the diameter of 2 mm, tilted with reference to the longitudinal axis 10 of the jet 2 by 20°, wherein the intersection 29 of their axes 28 is at the distance of 4.5 mm from the discharge opening 25 of the jet channel 22. The gas feeds 24 are led out from the clamp 7 of the jet 2 and connected directly to the feed pipe 27, being air tubing that supply the system with air at the pressure of 0.3 MPa.

Example 1B A Manually Controlled Plastering Machine with the Minimum Jet Adapter

[0057] A wheeled plastering machine fitted with a drive, a guide to which the jet adapter 1 as per Example 1A is attached in a movable and dismountable manner; the plastering machine is positioned to the wall; here the machine is levelled manually using a level by the levelling feet to be in a plane perpendicular to the plane where plaster is to be applied. Depending on the thickness of the planned plaster (5 mm) and the material flow rate through the plastering machine (30 l/min), the required speed of the holder 5 with the bracket 3 (30 mm/s) is calculated. This speed is set on the plastering machine. The longitudinal axis 10 of the jets 2 is perpendicular to the plastered wall. The holder 5 with the bracket 3 and the jets 2 is suspended to the lowest position of the machine where the longitudinal axes 10 of the jets 2 cross the plane of the plastered wall at the maximum 5 cm above the floor, and/or above the edge of the plastered area. Then the feed of pressurized gas set at 0.4 MPa to the jet channel 22 of the jet 2 is activated and so is the supply of material from the source—which may be a cistern fitted with a pump or mixing equipment with a pump—to the feed hose 35 at the speed of 30 l/min.The material is supplied by the feed hose 35 to the bracket 3, along which it is distributed to the jets 2; the material passes the jet channels 22 of the jets 2, is accelerated by the flowing pressurized air coming through the gas feeds 24 to the gas channel 22 and leaves the jet 2. At this moment, the movement of the holder 5 with the bracket 3 and jets 2 is activated at the required speed. The material is applied onto the wall from the floor towards the ceiling. The movement of the holder 5 with the bracket 3 and the jets 2 is stopped at the highest position of the machine where the longitudinal axes 10 of the jets 2 cross the plastered wall at the maximum 5 cm under the ceiling, and/or under the edge of the plastered area. The supply of material is deactivated and immediately after that the pressurized gas feed is deactivated too. In this way, it takes 65 s to apply plaster onto the area of 1 m.sup.2 of the wall. Then the plaster is either manually trowelled or the holder 5 with the bracket 3 and the jets 2 is dismantled from the plastering machine and a wiping blade 4 is attached to the guide of the plastering machine in a movable and dismountable manner. The plastering machine is installed again in the required position, the wiping blade 4 is manually set at the slope of −40° with reference to the horizontal plane, locked in the position and arranged at the bottom edge of the plastered area. The movement of the wiping blade 4 along the guide is activated in the bottom-up direction and the wiping blade 4 wipes the material applied onto the wall. In the upper position the movement of the wiping blade 4 stops. It is possible to tilt the wiping blade 4 to the slope of +40° with reference to the horizontal plane and repeat plaster trowelling similarly in the top-down direction.

[0058] When the entire band of plaster is wiped and trowelled, the machine is rearranged to allow the following band to follow the already plastered area and the whole process is repeated until the required area has been completed. For this reason it is preferred if the bracket 3 is fitted with the highest possible number of the jets 2 to plaster the largest possible area of the wall during one cycle.

Example 2A The Jet Adapter Fully Equipped, for Example for Fully Automatic Plastering Machine

[0059] The jet adapter 1 is fitted with a holder 5 with the bracket 3 mounted in a movable and dismountable manner. The length of the holder 5 is twice the length of that of the bracket 3 and is fitted with a movable system for the bracket 3, which can move within the holder 5 from one side to the other in a controlled manner. In addition, the holder 5 is fitted with two wiping blades 4 attached in a movable and dismountable manner, wherein the length of the wiping blades 4 is the same or smaller than that of the bracket 3 and the same or smaller than that of the holder 5. Between the bracket 3 and the holder 5 and also between the wiping blades 4 and the holder 5, guided pistons controlling the slope of the bracket 3, and/or the slope of the jets 2 and the slope of the wiping blades 4 are mounted. The bracket 3 has the diameter of 27 mm and the length of 620 mm and is fitted with one material supply opening 32 of the diameter of 27 mm and twelve jet openings 33 with the diameters of 12 mm at constant distances along the bracket 3. The material supply opening 32 of the bracket 3 is connected to the feed hose 35 with the internal diameter of 30 mm, which supplies material to the bracket 3 at the speed of 35 l/min. All jet openings 33 are fitted with jets 2. The jets 2 have the external diameters of 12 mm, follow the jet openings 33 and are installed in the plastic clamps 7 of the jets 2 secured by a screw, which keep the jets 2 in their places, and the jets 2 are also secured by the cases 6 of the jets 2 fixing the jets 2 pressed against the jet openings 33. The clamps 7 of the jets 2 and the cases 6 of the jets 2 have a compatible thread and internal space 9. The cases 6 of the jets 2 have two positions—the working one, where the jet 2 is opened and pressed against the jet opening 33, and the closed one, where the jet 2 is pressed against the jet opening 33, but it is on the side of its discharge opening 25 blinded by the case 6. Each jet 2 is 38 mm long and has one longitudinally arranged through-going jet channel 22 with the diameter of 4 mm and four gas feeds 24 with the diameter of 3 mm positioned according to the rules of rotational symmetry, tilted with reference to the longitudinal axis 10 of the jet 2 by 45°, wherein the intersection 29 of their axes 28 is at the distance of 10 mm from the discharge opening 25 of the jet channel 22. The gas feeds 24 enter the jet channel 22 on one side and the internal space 9 of the clamp 7 of the jet 2 and that of the case 6 of the jet 2 on the other side. The cases 6 of the jets 2 are connected to the feed pipe 27, being air tubing that supply the system with air at the pressure of 0.6 MPa.

Example 2B A Fully Automatic Plastering Machine with the Jet Adapter

[0060] The smart plastering machine equipped with gauges and a monitoring device and fitted with the jet adapter 1 according to Example 2A is arranged at the wall using a remote control and the plastering machine is preset the required thickness of plaster (15 mm). The plastering machine will scan the wall to be plastered by gauges, analyse the situation and install itself in the most appropriate position with reference to the wall to be plastered. The bracket 3 in the holder 5 is set in the extreme position on one side and also in the lower working position. Considering the fact that the holder 5 is fitted with two wiping blades 4 positioned parallel to the bracket 3, where one wiping blade 4 is positioned under the bracket 3 and the other one above the bracket 3, the plastering machine will reposition the holder 5 to the lowest possible position where the lower wiping blade 4 touches the floor, and/or the lower edge of the plastered area. The lower wiping blade 4 is adjusted by the plastering machine at the required offset from the wall with reference to the planned thickness of plaster and at the optimal calculated slope that ranges between −60° and −10° with reference to the horizontal plane. The other one, upper wiping blade 4 is set off the wall at this moment and its slope does not matter. The plastering machine also monitors the development of the slope of the jets 2, which is controlled by the pistons positioned between the bracket 3 and the holder 5. The plastering machine activates the feed of gas pressurized at the pressure of 0.6 MPa to the system and the supply of material from the source—which may be a cistern fitted with a pump or mixing equipment with a pump—to the feed hose 35. The material is supplied by the feed hose 35 to the bracket 3 (35 l/min.), along which it is distributed to the jets 2; the material passes the jet channels 22 of the jets 2, is accelerated by the flowing pressurized air entering the gas channel 22 by the gas feeds 24 and leaves the jet 2 at the flow rate of 2.9 l/min. though one of the jets 2. At that moment, the movement of the holder 5 with the bracket 3 and the jets 2 is activated and it moves upwards to the ceiling at the speed of 12 mm/s, while continuously applying plaster onto the wall. The material is usually applied onto the wall from the floor towards the ceiling. Immediately after the application of material onto the wall, the material is wiped by the wiping blade 4, which moves on the holder 5 along with the bracket 3. The movement of the holder 5 is stopped in the highest working position of the plastering machine where the upper wiping blade 4 has reached an obstacle—usually the ceiling. Then the bracket 3, controlled by the piston automatically tilts and the jets 2 are tilted with reference to the upper edge of the plastered area. The supply of material is automatically deactivated and immediately then the feed of pressurized gas is deactivated too. In this way, the area of 1 m.sup.2 of the wall is plastered and wiped within 165 s. Then the lower wiping blade 4 is either set off from the plastered area, and/or its slope is readjusted to +10° through +60° and the upper wiping blade 4 is pressed against the plastered area and its slope is also set at +10° through +60°. The plastering machine then moves with the holder 5 along the guide downwards at the same speed, i.e. 12 mm/s, while trowelling the plaster using the wiping blade(s). After the entire band of the applied plaster has been trowelled, the plastering machine moves the bracket 3 in the holder 5 to the opposite extreme side position and the entire process is repeated. After the other band of the plaster has been trowelled, the plastering machine is moved and the previous band is followed by the next one until the entire intended area has been plastered.

Example 3A The Jet Adapter Fully Equipped, for Example for Fully Automatic Plastering Machine

[0061] The jet adapter 1 is fitted with a holder 5 with the bracket 3 mounted in a movable and dismountable manner. The length of the holder 5 is three times the length of that of the bracket 3 and it is fitted with a movable system for the bracket 3, which can move within the holder 5 from one side to the other. In addition, the holder 5 is fitted with two wiping blades 4 attached in a movable and dismountable manner, wherein the length of the wiping blades 4 is the same or smaller than that of the bracket 3 and the same or smaller than that of the holder 5. Between the bracket 3 and the holder 5 and also between the wiping blades 4 and the holder 5, guided pistons controlling the slope of the bracket 3, and/or the slope of the jets 2 and the slope of the wiping blades 4 are mounted. The bracket 3 has the diameter of 40 mm and the length of 500 mm and is fitted with two material supply openings 32 of the diameter of 15 mm and eight jet openings 33 with the diameters of 18 mm. Both the material supply openings 32 of the bracket 3 are connected to the feed hoses 35 with the internal diameter of 15 mm, which together supply material to the bracket 3 at the speed of 35 l/min. All jet openings 33 are fitted with jets 2. The jets 2 have the external diameter of 19 mm, mate with the jet openings 33 and are all fitted in a single plastic clamp 7 of the jets 2, which has the shape of individual clamps 7 combined together to make one piece, that can be put on the bracket 3 from the side, and secured by at least one screw, which keeps the jets 2 in place, and the jets 2 are also secured by eight cases 6 of the jets 2 fixing the jets 2 pressed against the jet openings 33. The clamp 7 of the jets 2 and the cases 6 of the jets 2 have a compatible thread and internal space 9. In the internal space 9, a spring 8 is located that presses the jet 2 against the case 6 of the jet 2 thus sealing the jet 2—case 6 of the jet 2 connection. Each jet 2 is 55 mm long and has one longitudinally arranged through-going jet channel 22 with the diameter of 8 mm and six gas feeds 24 with the diameter of 7 mm arranged in accordance with the rules or rotational symmetry tilted with reference to the longitudinal axis 10 of the jet by 60°, wherein the intersection 29 of their axes 28 is at the distance of 32 mm from the discharge opening 25 of the jet channel 22. The gas feeds 24 enter the jet channel 22 on one side and the internal space 9 of the clamp 7 of the jet 2 and that of the case 6 of the jet 2 on the other side. The cases 6 of the jets 2 are connected to the feed pipe 27, being air tubing that supply the system with air at the pressure of 0.8 MPa.

Example 3B A Fully Automatic Plastering Machine with the Jet Adapter and Blinded Jets

[0062] The smart plastering machine equipped with gauges and a monitoring device and fitted with the jet adapter 1 according to Example 3A is arranged at the wall using a remote control and the plastering machine is preset the required thickness of plaster (10 mm). The plastering machine will scan the wall to be plastered by gauges, analyse the situation and install itself in the most appropriate position with reference to the wall to be plastered. The bracket 3 in the holder 5 is set in the extreme position on one side and in the lower working position. Considering the fact that the holder 5 is fitted with two wiping blades 4 positioned parallel to the bracket 3, where one wiping blade 4 is positioned under the bracket 3 and the other one above the bracket 3, the plastering machine will reposition the holder 5 to the lowest possible position where the lower wiping blade 4 touches the floor, and/or the lower edge of the plastered area. The lower wiping blade 4 is adjusted by the plastering machine at the required offset with reference to the planned thickness of plaster and at the optimal calculated slope that ranges between −60° and −10° with reference to the horizontal plane. The other one, upper wiping blade 4 is set off the wall at this moment and its slope does not matter. The plastering machine also monitors the development of the slope of the jets 2, which is controlled by the pistons positioned between the bracket 3 and the holder 5. The plastering machine activates the feed of pressurized gas by the supply pipe 27 at the pressure of 0.8 MPa to the system and the supply of material from the source—which may be a cistern fitted with a pump or mixing equipment with a pump—to the feed hose 35. The material is supplied by the feed hose 35 to the bracket 3 (35 l/min.), along which it is distributed to the jets 2; the material passes the jet channels 22 of the jets 2, is accelerated by the flowing pressurized air coming to the gas channel 22 by the gas feeds 24 and leaves the jet 2 at the flow rate of 4.3 l/min. per jet 2. At that moment, the movement of the holder 5 with the bracket 3 and the jets 2 is activated and it moves upwards to the ceiling at the speed of 25 mm/s, while continuously applying plaster onto the wall. Immediately after the application of material onto the wall, the material is wiped by the wiping blade 4, which moves on the holder 5 along with the bracket 3. The movement of the holder 5 is stopped in the highest working position of the plastering machine where the upper wiping blade 4 has reached an obstacle—usually the ceiling. Then the bracket 3, controlled by the piston automatically tilts and the jets 2 are tilted with reference to the upper edge of the plastered area. The supply of material is automatically deactivated and immediately then the feed of pressurized gas is deactivated too. In this way, the area of 1 m.sup.2 of the wall is plastered and wiped within 80 s. Then the lower wiping blade 4 is either set off from the plastered area, and/or its slope is readjusted to +10° through +60° with reference to the horizontal plane and the upper wiping blade 4 is pressed against the plastered area and its slope is also set at +10° through +60° with reference to the horizontal plane. The plastering machine then moves with the holder 5 along the guide downwards at the same speed, i.e. 25 mm/s, while trowelling the plaster using the wiping blade(s) 4. After the entire band of the applied plaster has been trowelled, the plastering machine moves the bracket 3 within the holder 5 so that the newly applied band follows the already applied band of plaster and the entire process is repeated. After the other band of the applied plaster is has been trowelled, the plastering machine moves the bracket 3 in the holder to the opposite extreme side position. However, at this moment it is necessary to apply plaster onto a band narrower than the bracket 3. The two extreme side positions of the jet 2 are thus blinded by blinding pins that have the thickness of 7 mm and the length of 65 mm and are equipped with a thread or profiling. Via the case 6 of the jet 2, a blinding cap is fitted that has a thread and/or shape corresponding to the profiling of the blinding pin, thus locking the blinding pin in its place. The entire process of plaster application is repeated with the difference that the speed of material feeding is reduced to 25 l/min. After the third band of plaster has been trowelled, the plastering machine is moved to a different place by the remote control. If the wall to be plastered is significantly curved, the smart plastering machine also sets the seating of the wiping blades 4 to the plastered wall at an angle with respect to the plane of the wall thus reducing the wall curvature.
