Abstract
Helical body with blades for cutting, stirring, removing and cleaning in solids and closed and open tubular shapes. The blades create more points to cut and contact with less material and remove what they cut and withdraw in the same movement. In ear cleaning they reduce the risk of pushing in the cerumen. The helicoid to remove earwax is manufactured with the same processes and machines of the art of swabs, adding two steps, preforming and forming. This one, by placing halves of helicoid molds in bands or cylinders where, by pressure, a vacuum, and heat, they form the blades. The machine produces quantities per minute similar to the current ones. Uses of the invention are possible in cutting and removal of rocks, in mechanical tools for working on metals or hard materials, in medicine for removal and extraction in ducts, veins and arteries, in personal use and domestic utensils where blades replace fibers.

9. Helicoid body manufacturing process to cut, remove, clean CHARACTERIZED by the following steps: Step 1—Set up the material from the manufacturer, grip and helicoid material, this one can have in several forms: 1. Material with which the helicoid is manufactured cotton, cellulose or other material in the art, appropriate to manufacture the helicoid body, which can have various forms: a) flat band 8 to 10 mm wide, 1 to 2 mm thick. b) inclined plane band 8 to 10 mm wide, where one side is 3 to 4 mm thick and decreases to 1 to 2 mm towards the other side. c) cylindrical strip, like a thread, with a diameter of 1 to 2 mm. In any of these forms the material is pre-cut or continuous. In this case the preforming step includes the cutting of each part when spinning. 2. Preformed grip, made of impregnated paper, cellulose, wood, 50 to 60 mm long and 2 to 3 mm in diameter. It can have different lengths and diameters depending on the application for which it is intended. Step 2—Add emollient to each end of the grip to help giving and keeping shape, remove fiber particles that can come off inside the ear, by dispersion in cold, hot, steam, about 0.025 ml. Step 3—Preform the helicoid body by wrapping 0.5 to 1 gram of cotton, cellulose, or other material with suitable characteristics (soft, absorbent, non-particles) around the two ends of the grip. This winding results in a conical helical body with diameters at the base of 5 to 6 mm and at the upper end of 2.5 to 5 mm, which are 25 to 30% larger than the final size of the helical body for cleaning wax. These measures are modified depending on the application to which it is intended. The pre-shape can be made in several ways: a) Place the grip (11) in a band or cylinder, which has a cavity with its shape and means to make it rotate. b) Mold a flat band of material such as cotton in the middle of a longitudinally cut mold that has the shape of the helicoid in low relief, hold independently of the grip (11). This half of the mold is engraved in a block 20 to 23 mm square and 6 to 13 mm high and varies according to the application for which it is intended. The movement of the band or the cylinder causes the material to be rolled to come closer and remains in contact with each end of the grip (11) and in proximity to the cavity that has the half mold of the helicoid engraved in low relief. At the ends of the grip (11) the material, such as cotton, is hold, rotated and rolled over the half of the mold, forcing it to take the shape of the half mold of the helicoid body. At each end 0.02 to 0.03 grams of the material are wound. The movement of the band or the cylinder brings the pre-formed helical body to a storage space. c) Roll up a cylindrical strip of material at each end of the grip, giving more winding time at the base of the cone and moving towards the smaller diameter. A cone-roll with more material at the bottom will result. d) Mold a cylindrical strip by rolling against half a mold while the material source moves longitudinally to the axis of the mold. Step 4—Place the preformed helicoid bodies in a container that is close to the band or cylinder that gives the final shape. Step 5—Arrange the preformed helicoid bodies in the grip that is on a band and that contains the halves of the mold of ten helicoid bodies, band that moves as it is currently done in the art. Step 6—Give final shape in cycles. Ten boxes with half helical body mold and grip are accommodated in a frame on a moving belt. The grip has in its lower part a connecting hole (24) to a space that creates a vacuum in the ten boxes. In the boxes there are ten pre-formed helical bodies. Aligned and on top of the first and inversely, there is another group of ten boxes and molds that descends and contacts the group that is on the band, making hermetic closure with gaskets (not shown). Both groups move and during the displacement mechanical pressure and vacuum are produced in both groups, which will force the material, which has been treated with emollient, to take the low-relief shape of the mold. Then the set on top raises and moves back to stand on top of the group of ten boxes moving on the band, to start another cycle. Times and distances are synchronized so that the two groups coincide in each cycle. The cycle time depends on the target production. If it is 2,000 units per minute, the cycle of descending, contacting, displacing the boxes moving with the belt, emptying, raising and moving back to place again on the group moving on the belt, and if in each cycle form ten units, the time will be (2,000/10=200 cycles/minute), in 60 seconds/200 cycles=0.3 seconds per cycle). Negative pressure is exerted for 0.15 seconds, half the cycle time. These cycles and times are currently applied in various production systems. This process can also be made with rotating cylinders on whose surface there are molds of the helical body. One preformed mold is accommodated in each mold. At each point of tangency, when they come into contact, pressure and vacuum are produced, which are made continuously by rotation and give the final shape. Step 7—Add agglutinating to each end, dry, then pack.

DETAILED DESCRIPTION OF THE INVENTION
[0045] The following figures illustrate generally the proposed invention but are not limited to these illustrations.
[0046]
[0047]
[0048]
[0049] Due to its circular shape, the top and bottom plant view of the helicoid will show continuous concentric circles that can be of different diameter and number.
[0050]
[0051]
[0052]
[0053] With the same amount of material used in the ovoid shape, this helical body creates a larger contact area and smoother, more cutting angles, removes, removes wax or any other material from the duct with less pressure, the outer edges of blades (5) of the blades contact smaller points and on a different surface than a contact element with only an ovoid general surface. The curvature of the blade helps to remove and withdraw material more effectively without the risk of pushing it; the base wider than the apex reduces the risk of damaging internal parts of the ear.

Manufacture Process
[0063] The new helical body for removing and withdrawing ear wax can be built with the same known machines, if part of the process for creating the helical blades is modified, as described.
[0064] Step 1—Set up the material from the manufacturer, grip and helicoid material, this one can have in several forms:
[0065] 1. Material with which the helicoid is manufactured cotton, cellulose or other material in the art, appropriate to manufacture the helicoid body, which can have various forms: [0066] a) flat band 8 to 10 mm wide, 1 to 2 mm thick. [0067] b) inclined plane band 8 to 10 mm wide, where one side is 3 to 4 mm thick and decreases to 1 to 2 mm towards the other side. [0068] c) cylindrical strip, like a thread, with a diameter of 1 to 2 mm.
[0069] In any of these forms the material is pre-cut or continuous. In this case the preforming step includes the cutting of each part when spinning.
[0070] 2. Preformed grip, made of impregnated paper, cellulose, wood, 50 to 60 mm long and 2 to 3 mm in diameter. It can have different lengths and diameters depending on the application for which it is intended.
[0071] Step 2—Add emollient to each end of the grip to help giving and keeping shape, remove fiber particles that can come off inside the ear, by dispersion in cold, hot, steam, about 0.025 ml.
[0072] Step 3—Preform the helicoid body by wrapping 0.5 to 1 gram of cotton, cellulose, or other material with suitable characteristics (soft, absorbent, non-particles) around the two ends of the grip.
[0073] This winding results in a conical helical body with diameters at the base of 5 to 6 mm and at the upper end of 2.5 to 5 mm, which are 25 to 30% larger than the final size of the helical body for cleaning wax. These measures are modified depending on the application to which it is intended. The pre-shape can be made in several ways: [0074] a) Place the grip (11) in a band or cylinder, which has a cavity with its shape and means to make it rotate. [0075] b) Mold a flat band of material such as cotton in the middle of a longitudinally cut mold that has the shape of the helicoid in low relief, hold independently of the grip (11). This half of the mold is engraved in a block 20 to 23 mm square and 6 to 13 mm high and varies according to the application for which it is intended.
[0076] The movement of the band or the cylinder causes the material to be rolled to come closer and remains in contact with each end of the grip (11) and in proximity to the cavity that has the half mold of the helicoid engraved in low relief. At the ends of the grip (11) the material, such as cotton, is hold, rotated and rolled over the half of the mold, forcing it to take the shape of the half mold of the helicoid body. At each end 0.02 to 0.03 grams of the material are wound. The movement of the band or the cylinder brings the pre-formed helical body to a storage space. [0077] c) Roll up a cylindrical strip of material at each end of the grip, giving more winding time at the base of the cone and moving towards the smaller diameter. A cone-roll with more material at the bottom will result. [0078] d) Mold a cylindrical strip by rolling against half a mold while the material source moves longitudinally to the axis of the mold.
[0079] Step 4—Place the preformed helicoid bodies in a container that is close to the band or cylinder that gives the final shape.
[0080] Step 5—Arrange the preformed helicoid bodies in the grip that is on a band and that contains the halves of the mold of ten helicoid bodies, band that moves as it is currently done in the art.
[0081] Step 6—Give final shape in cycles. Ten boxes with half helical body mold and grip are accommodated in a frame on a moving belt. The grip has in its lower part a connecting hole (24) to a space that creates a vacuum in the ten boxes. In the boxes there are ten pre-formed helical bodies. Aligned and on top of the first and inversely, there is another group of ten boxes and molds that descends and contacts the group that is on the band, making hermetic closure with gaskets (not shown). Both groups move and during the displacement mechanical pressure and vacuum are produced in both groups, which will force the material, which has been treated with emollient, to take the low-relief shape of the mold. Then the set on top raises and moves back to stand on top of the group of ten boxes moving on the band, to start another cycle.
[0082] Times and distances are synchronized so that the two groups coincide in each cycle. The cycle time depends on the target production. If it is 2,000 units per minute, the cycle of descending, contacting, displacing the boxes moving with the belt, emptying, raising and moving back to place again on the group moving on the belt, and if in each cycle form ten units, the time will be (2,000/10=200 cycles/minute), in 60 seconds/200 cycles=0.3 seconds per cycle). Negative pressure is exerted for 0.15 seconds, half the cycle time. These cycles and times are currently applied in various production systems.
[0083] This process can also be made with rotating cylinders on whose surface there are molds of the helical body. One preformed mold is accommodated in each mold. At each point of tangency, when they come into contact, pressure and vacuum are produced, which are made continuously by rotation and give the final shape.
[0084] Step 7—Add agglutinating to each end, dry, then pack.
