(7) FIGS. 6a-f illustrate a further embodiment of the mounting means in accordance with the invention; and

(8) FIG. 7 illustrates a cross sectional elevation of the embodiment of FIGS. 6a-f along lines A-A and B-B.

(9) Referring firstly to FIGs. 1 and b, there is illustrated a garment 2 such as a pair of trousers, which have crease lines 4 formed therein. The crease lines 4 are shown in position on a support surface 6 and it is shown that the crease lines 4 are located in respective grooves 8 which may be V or gull wing shaped in sections 8 which run substantially parallel along the support surface. With the crease lines 4 in position, then in accordance with the invention, respective cartridges 10 in which the fluid resin material is held can be used to deposit, from an aperture in their respective nozzles 14, a ribbon 12 of the fluid material therefrom, along the length of the crease line, with the aim being to ensure that the ribbon of resin which is dispensed is dispensed into the base of each crease line as there is relative movement between the cartridges and the garments. In this embodiment the cartridges 10 and mounting means 22 therefore are moved as indicated by arrow 24 such that the nozzles 14 move along the crease lines 4 Once applied, the resin then cures and serves to maintain the crease line in the garment for a longer period of time than if the resin was not present and thereby maintaining the appearance of the garment.

(10) FIG. 2 illustrates a cartridge 10 of a type which is suitable for use in accordance with the invention and the cartridge comprises a body 18 which has a cavity therein and in which the fluid resin is held. At one end 20 of the cartridge there is provided a connection for a pressurised gas connection which causes movement of a piston 28 in the cavity in the direction of arrow 30 so as to cause the movement of the resin towards the opposing end 32 at which there is provided a tongue 34 with nozzle 14 secured therein. A bore passes through the tongue and hence into a bore in the nozzle which in turn leads to an elongate aperture in the nozzle which allows the ribbon of resin to be applied from the cartridge 10. The cartridge, or mounting means therefore, can also include guide means in the form of fins 36 which are aligned with the outlet of the nozzle along the longitudinal axis 38 of the cartridge so that these are moved along the crease line and groove in advance of the nozzle with respect to the direction of movement so as to further assist in ensuring that the ribbon of the material is applied into the base of the crease line 4 during the relative movement between the garment and the cartridge to apply the resin material.

(11) The cartridges 10 are typically provided as a disposable item such that once the resin therein has been used, the cartridge can be disposed or alternatively, the cartridge could be provided to be refilled. In either case, it is desired that the cartridge can be removed from the apparatus for disposal and replacement, or refilling.

(12) In accordance with the invention, the apparatus further includes a mounting means 22 which, in this embodiment includes receiving locations for two cartridges 10 and allows the first and second cartridges to be located with their respective longitudinal axes 38 substantially parallel to each other and spaced apart by a predetermined distance X The distance of separation will typically be that of a space in between the two grooves 8 in the work surface 6 so as to allow the resin material to be applied from the said first and second cartridges 10 simultaneously along the two crease lines 4, 4′ each respectively located in a groove 8. It will therefore be appreciated that this will allow the application of the resin material from two cartridges and hence at a much faster rate than by using one cartridge, although it should be appreciated that the mounting arrangement which is now described for the cartridges can be effective and provide advantage in the mounting of only one cartridge. In order to allow the use of the two cartridges 10, it is important that the same are held in a parallel relationship and that this parallel relationship can be ensured each time the respective cartridges are placed into the mounting means.

(13) In addition, it is important that the cartridges 10 are movable within a predetermined range of movement in order to allow variations in the location of the creases 4 and/or the grooves 8 to be taken into account and ensure that the resin material line follows the base of the crease 4 as, if this is not achieved then the resin material would be applied to one side of the crease which would not be as effective in extending the lifetime of the crease. In accordance with the invention, this is achieved by providing a degree of cartridge movement in the mounting means 22 to allow relative movement between the cartridges and/or between the cartridge and the mounting means and thereby allow relative movement of the cartridges whilst ensuring that the same are encouraged to move back to the predetermined spacing X.

(14) In FIGS. 3a-c one embodiment of the mounting means 22 is shown and it can be seen that the mounting means comprise a first part 40, a further part 42 for connection with cartridge 10 and a further part 42′ for connection with cartridge 10′. In FIG. 3b, cartridge 10 is removed for ease of illustration and in FIG. 4c part of the first part 40 of the mounting means is shown in cross section along line A-A.

(15) The parts 42, 42′ are provided with a receiving housing 44 into which the end 32 of the cartridge is located and the tongue 34 is inserted along a slot 46 in the housing. The part 42,42′ also includes a shaped arm 48 which is received in a shaped recess 50 in the part 40 of the mounting means 22. The arm 48 and recess are shaped so as to allow relative movement about a pivot axis 52 which is typically in line with the axis 38 of the cartridge and the relative movement is rotational movement as indicated by arrows 56, 58 with the range of movement defined by the contact between the arm 48 and the sidewalls 54 of the recess.

(16) An alternative embodiment is illustrated in FIGS. 4a-c wherein there is shown a mounting means 22 which includes therein receiving housings 62, 62′ which are provided to receive the end 32 of the cartridges 10. 10′ therein. In FIG. 4b, cartridge 10 is removed for ease of illustration and in FIG. 4c part of the first part 40 of the mounting means is shown in cross section along line B-B. The tongue 34 of each cartridge is received in a slot 60, 60′ and it is the degree of movement between the walls 64 of the slot 60 and the walls 66 of the tongue 34 which define the possible range of movement in the directions of arrows 68, 70 about the axes 38 of the cartridges 10, 10′.

(17) A third embodiment is illustrated in FIGS. 5a and b. In this case the mounting means 22 is shown to comprise two portions 72, 74, although it should be appreciated that it would still be possible to use only one portion as in the other embodiments.

(18) The first portion 72 is mounted at the tongue 34, 34′ end 76, of the cartridges 10, 10′ and the second portion 74 is mounted at the inlet end 78 of the cartridges 10, 10′ so as to retain the same in a substantially parallel relationship and with the nozzles 14 substantially perpendicular to the support surface and garment thereon. In this relationship it can be ensured that the outlets from the respective cartridge nozzles lie in and are moved along the base of the respective crease lines so as to move accurately and effectively apply the fluid into the base of the crease as the cartridges are moved along the respective crease lines of the garment.

(19) On occasion, the grooves 8 in the support surface in which the crease lines lie may deviate from straight and parallel due to inconsistencies when manufacturing the same and/or due to wear and/or due to warping of the support surface. In this embodiment, in order to allow the nozzles 14, 14′ of the cartridges 10,10′ to follow the base of the groove 8 and hence the crease line lying therein, the cartridges 10. 10′ are movable linearly with respect to the mounting means body within a predefined range of movement. The movement is linear as indicated by the arrows 80 and are along axes 82,84 which are substantially perpendicular to the longitudinal axes 38, 38′ of the cartridges 10, 10′. The movement is achieved and controlled in this embodiment by providing telescopic sections 86 in each of the portions 72, 74 between the cartridges 10, 10′.

(20) In order to ensure that when the cause for movement of the cartridges has been removed the cartridges return to the default position, the portions 72, 74 include springs 88 which can be overcome by the movement force exerted on the nozzles, and in turn the cartridge, by the deviation of the grooves 8 as the guide fins 36 follow the same as the cartridges are moved along the respective crease lines and grooves to apply the fluid. However the springs are sufficiently strong such that when the movement force is removed the springs exert a force so as to move the cartridges 10, 10′ back into the default positions with the required spacing.

(21) Referring now to FIGS. 6a-f there is illustrated a further embodiment of mounting means 102 in accordance with one embodiment of the invention.

(22) Once again, the mounting means 102 include a body 104 and, located with the body, are first holding means 106 and second holding means 108. Each of the holding means is provided to receive a cartridge 110, 112 therein and to thereby position the respective cartridges with regard to the body.

(23) Typically, the spacing X between the cartridges and in particular, the nozzles of with dispensing apertures 114 116 of the cartridges, when located in the holding means, is substantially the same as the spacing between the respective garment crease lines when located in the grooves 8 in the work surface and thereby allow the resin to be simultaneously dispensed from the respective cartridges through the aperture in the nozzles and along the base of the crease lines. In one embodiment the spacing X is 55 mm. In one embodiment the spacing between the cartridges is adjustable to allow the same to be altered to react to being used with support surfaces which have grooves with a different spacing between the same. Typically once the adjustment has been made the spacing is locked so as to prevent further alteration during the use of the mounting means with the particular work surface.

(24) The guidance of the movement of the mounting means and hence cartridges 110, 112 along the crease lines, is again achieved by the provision of guide fins 120 on each of the cartridges which are located such that when the cartridges are moved with the mounting means, the guide fins are in advance of the dispensing nozzle and can therefore be moved along the crease and hence grooves in advance of the resin which is being dispensed from the cartridge nozzle.

(25) Thus, in accordance with the invention, the mounting means as shown, allow the simultaneous dispensation of resin from the two cartridges 110, 112 in a controlled manner.

(26) The body 104 also includes a handle portion 122 which is located on a surface 124 of the body opposing that to which the holding means are located. The handle is provided with a head portion 126 which is provided to be gripped by the user in order to move the body, mounting means and cartridges as an integral unit. The handle can be of any desired form but it is believed that the shape as shown is particularly advantageous in being comfortable to be gripped whilst at the same time, ensuring that a secure grip can be achieved to move the mounting means and cartridges in a controlled manner. The head portion 126, in this embodiment, is rotatable about an axis 128 so as to aid in the continued straight line movement of the body by the user as the distance of the body and angular orientation of the same from the user changes and therefore maintains a straight line of movement along the groove and avoids the possibility of the movement of the mounting means being along a bend as the user. The rotation of the head portion 126 allows the user to continue to grip it in the same way and move the mounting means in a straight line whilst the relative position of their hand with respect to the body 104 changes.

(27) In one embodiment, the body and/or handle may also include a control switch 130 for user actuation to allow the switching on and off of the pressurised fluid source which is directed to both of the cartridges 106, 108 in order to move the pistons which are located within the respective cartridges towards the dispensing nozzles and hence move the resin which is to be dispensed towards the nozzle under pressure to ensure that the resin is emitted from the nozzle aperture in a continuous manner. In the embodiment shown the switch 130 is located on the head portion to be selectively moved. In another embodiment the head portion may be the switch and can be activated by selectively moving the same to different positions along the axis 128 to activate a microswitch located in the body of the mounting means.

(28) Typically the pressurised are source includes a regulator to allow equal gas, typically pressurised air flow into the respective cartridges. This and/or manual adjustment allows the air supply to be adapted to suit different potential flow rates of the fluid material in particular cartridges and/or to take into account variation in environmental conditions which may affect the flow rate of the fluid.

(29) Typically, the holding means and/or handle are located with the body in a manner to allow limited movement of the same with respect to the body 104 so as to take into account any variation in movement of the cartridge as it is moved along the crease line whilst, at the same time, ensuring that the resin is still applied into the crease rather than to a side of the same.

(30) FIG. 7 illustrates the mounting means of FIGS. 6a-f with the top part of the body 104 removed for ease of illustration and it is shown the manner in which, for each of the cartridges 106, 108, there are provided first and second supports 202,204 and 202′,204′ respectively. Each of the supports has a channel in which there is provided a bearing 206. In turn, the bearing has an aperture which receives therein a shaft 208 and the shaft extends along the width of the body 104. Each shaft 208 is received in end supports 210 at opposing ends of the same which therefore retain the shaft in position with respect to the body. Spaced inwardly of the same, there are provided stops 212 which are sized so as to allow the shaft to pass there through but to prevent the carrier 204 of the cartridge from passing there through. This therefore means that the range of movement in the direction of arrows 210 212, is restricted by the stops whilst, at the time, the gap between the stops 212 and the end face 204 of the carrier, allow a limited scope of movement and hence a limited scope of limited movement of the cartridge attached to the carrier 204. Thus, in accordance with the invention it will be seen that the relative spacing between the cartridges is adjustable as cartridges are moved in the direction 214 along the respective crease lines in the garment a and grooves 8 in the work surface. Once again springs, not shown, can be provided to act, in this case, between a stop 212 and the end surface of the adjacent carrier 204,206, 204′,206′, in order to bias the respective cartridge position to a default position.

(31) The need to provide the possibility of movement between respective cartridges and/or a cartridge with respect to the body, is required in order to allow the nozzle through which the fluid material is dispensed from each cartridge, to remain in a plane which is substantially perpendicular to the longitudinal axis of the body of the mounting means. The mounting means body, in turn, is provided to be substantially parallel with the work surface in which the grooves 8 are provided and upon which the garment to which the fluid material is to be applied, is located. This, in turn, means that the fluid material is dispensed into the base of the crease lines of the garment and along the same to thereby ensure that the fluid material is located in the required position so as to act to maintain the crease in the garment. If the fluid material is not dispensed into the crease line but, instead, is applied onto the garment surface adjacent to the crease line then the fluid material does not act on the crease and therefore does not provide the required permanence of crease characteristic. Thus, if the linear movement between the cartridges and/or the cartridges and the body was not possible the line of application of the fluid can diverge from the line along which the crease follows the groove in the surface.

(32) It will therefore be appreciated that in accordance with the invention, there is provided apparatus which allows the application of resin material along crease lines in substantially less time than the conventional systems which only use one cartridge at a time. In addition, the quality of application of the resin is maintained and it is ensured that the application of the resin is along the base of the crease as required.
