Radial toothbrush

The present invention relates to a radial toothbrush manufacturing method and a radial toothbrush, and in detail, relates to a method for manufacturing a radial toothbrush that can be used for a toothbrush or various cleaning or liquid coating applications, and the manufacturing method described above. A radial toothbrush, especially a toothbrush using the above radial toothbrush.

In general, from the point of view of oral cleaning and prevention of tooth decay, it is easy to associate with the removal of tartar attached to the teeth. However, in order to prevent alveolar pyorrhea in which 2 teeth are juxtaposed with tooth decay, it is very important to remove the presence of Tartar in the periodontal pocket between the tooth and the tooth. In order to prevent the above-mentioned alveolar pyorrhea, the tooth is massaged, and even in order to clean the inside of the periodontal pocket efficiently, various brushing methods are proposed, and a representative method is to insert the bristle tip as much as possible with respect to the pinion at 45 degrees. The bus method in the pocket and repeated small back and forth movements is very famous. In order to cope with these brushing techniques, a toothbrush that allows the bristles to be finely machined as much as possible has been developed, and a product in which the toothbrush portion itself is rotatable or the like is being developed. As described above, until now, attempts have been made to review the shape and material of the bristles or the direction of the bristles to develop a product that can effectively clean the periodontal pocket.

[Patent Document 1] Japanese Shikai Show 59-41125

However, as described above, the technique such as the bus method emphasizes the need to accurately perform the fine vibration of the toothbrush before and after the toothbrush tip can be inserted into the tooth pocket at a correct angle, and similarly, even if it is used The rotatable toothbrush portion of the cylindrical hairs, or the electric toothbrush that does not require a slight vibration of the tip of the toothbrush, does not require the high skill of inserting the bristles into the periodontal pocket at the correct angle.

The present invention provides an irrelevant electric toothbrush or a general manual toothbrush in view of the above facts, and it is not necessary to pay attention to the correct contact angle with respect to the tooth surface to be cleaned, and the tooth surface can be effectively cleaned by simple back and forth motion even from any angle. And a radial toothbrush in the periodontal pocket.

The present invention relates to a radial toothbrush. The above objects are achieved by the invention of each patent application. In other words, in the first aspect of the invention, the long fibers are cut into a short fiber shape, and the bundled short fibers are used as a fiber bundle, and the longitudinal end faces of the fiber bundles are melted, compressed, and fused, whereby the fibers are compressed. In the deformation, the interfiber space of the fiber bundle disappears, and at the same time, the melted short fiber is compressed and deformed, and the cross-sectional area of the fiber bundle is reduced, and the fusion is integrated. At this time, the gap between the fiber bundles which are melted, compressed and melted disappears, and the melted short fibers themselves are also compressed and deformed to reduce the sectional area, so the fiber bundle cross-sectional area and the free end fiber at one end side There is a difference between the beam splitting areas, and the free end fiber bundle system near the one end side is pressed and expanded to diffuse into a radial shape. When the vicinity of one end side of the melted, compressed, and melted side is observed in more detail, the melted fiber bundle is pushed and diffused by compression, whereby it can be easily deformed, so that it does not break at this portion, and is free. The end systems are dispersed and arranged in a radial shape, and one end side of the melted, compressed, and fused ones is completely melted and fused to form an integration. In this case, the mechanism for melting and fusing the fiber bundle is not only a thermal friction method implemented by a supersonic fused speaker described later, but also the body of the jig is heated by various heat sources such as an electric heater or an electromagnetic induction. In the production step, of course, in order to improve the mold release property of the jig and the resin fiber, the surface of the jig is subjected to Teflon processing or the like, and the fiber bundle integrated after the molding is easily taken out.

Further, in order to increase or decrease the diffusion spread angle, the cross-sectional area of the fibers to be formed may have a difference in thickness between one end side and the free end of the melted, compressed, and melted. In this case, when it is assumed that the cross-sectional area of one end side of the melted, compressed, and fused is smaller than the free end, the difference in the cross-sectional area of the fiber bundle is reduced by the disappearance of the gap between the fibers on one end side and the sectional area due to the fiber deformation. It will be bigger, so the angle of expansion of the free end will become larger. On the contrary, the degree of expansion of the free end will become smaller. However, when the ends of the fiber are used with small sections, the toothbrush will expand at a wide angle. A toothbrush with a soft tip is formed.

The first aspect of the invention is a step of self-melting, compressing, and fusing the fiber bundle with the two bisectors at the approximate center point of the cross-sectional shape of the melted, compressed, and fused fiber bundles. The cross-sectional shape of the cross-sectional line is connected to the opening of the fiber bundle at the opening in the parallel direction, and the length of the fused portion has a plate-shaped susceptor having the same thickness, and the insertion setting is estimated to be any number of deformations due to compression and fusion. One end of the fiber bundle has a width diameter and a thickness diameter which are the same as the opening portion which is attached to the open end of the plate-shaped receiving opening of the jig, and the ultrasonic wave is symmetrical with the cross-sectional shape of the base portion of the opening. The compression fixture of the fused speaker is compressed in the direction of the fiber bundle, and at the same time, the ultrasonic wave is emitted, or the heat-resistant test fixture and the compression fixture are used to melt, compress and fuse the fiber bundle, whereby the fiber bundle is melted. And melting, and by being subjected to melting, compression and fusion by the jig and the compression jig, a difference is made between the cross-sectional area of the fiber bundle at one end side and the cross-sectional area of the fiber bundle at the free end, and the free end fiber bundle near the one end side is Pressure expansion, the free end of the fiber bundle as a whole will become radially spread. The jig can be opened on the opposite side of the opening, and in this case, after the radial toothbrush is formed, it is cut at the fiber bundle fusion portion.

In the second aspect of the invention, the portion of the fiber bundle that is adjacent to the jig is pressed and expanded by the melt compression, and is deformed easily. In this step, the fiber bundle is returned at a predetermined angle with respect to the longitudinal axis of the diffused fiber bundle. Pressing the plate-shaped diffusion jig or the wrap-shaped diffusion jig at the same time, whereby the fiber bundle of the melt portion is thermally set before the fiber bundle is cooled and hardened so as to be from the free end side to the periphery from the fiber bundle to the periphery, the fiber The beam system is radially expanded at a local arbitrary density or uniform density; the surface density of the free end side fiber bundle is freely adjusted, and at the same time, the direction of the free end fiber bundle with respect to the longitudinal axis direction can be formed at an arbitrary angle. When the above steps are carried out after the fiber bundle is formed, the fiber bundle shape is arranged into an arbitrary diffusion shape by using a diffusion jig, and while being thermally set, the fiber can be deformed into a parabolic curved shape.

When the third invention is used, the configuration of the fiber bundle fibers constituting the radial toothbrush need not be the same shape or material, and the diameter of the cross-sectional area is changed by the bristle portion of the radial toothbrush in a single material, or When the resin is composed of a resin having different mechanical properties depending on the site, the hardness of the toothbrush can be changed depending on the site, and the performance can be exhibited in accordance with the purpose of use. In addition, in order to exhibit a visual effect, it may have An object whose color tone changes.

According to a fourth aspect of the invention, in the first aspect of the invention, the fiber bundle composed of the fibers of the single material has a core sheath structure having a different melting point in the core portion and the sheath portion, and a heat having a lower melting point of the sheath portion than the core portion. The thermoplastic resin fiber is configured such that the thermoplastic resin fiber of the sheath portion is uniformly melted and melted while maintaining the shape of the core thermoplastic resin fiber in the step of melting, compressing, and melting one end side. And integration. Further, since the cross-sectional shape of one of the fibers after melting, compression, and fusion is maintained in the shape of the core, there is no difference in the position, and the fibers constituting the fiber bundle can maintain a uniform cross-sectional shape.

According to the fifth aspect of the invention, the fibers constituting the fiber bundle are applied by applying a spiral shape or a wave shape, whereby the volume on the non-melting, non-compressing, and non-melting sides is large, and the fibers can be more diffused.

According to a sixth aspect of the invention, the fiber bundle constituting the radial toothbrush of the first aspect of the invention is formed of a thermoplastic resin non-woven fabric or a porous ribbon having a higher compressibility, and is melted, compressed, and melted at one end side, and is not woven. Or the porous ribbon may be deformed, but because these materials have high incompressibility, there is a large difference between the fiber bundle cross-sectional areas of the one end side and the free end, and therefore, the free end fiber bundle system is closely radiated. Diffusion can increase the density of the free end.

According to a seventh aspect of the invention, in the first invention, the second invention, the third invention, the fourth invention, the fifth invention, or the sixth invention, when the fiber bundle is melted, compressed, and fused, the insertion type is fixed or rotatably Forming the part to be fixed, or integrating one end of the fixed end side by melting, compressing, and melting, and attaching it to the resin handle by fusion or the like, and arranging the longitudinal center axis of the fiber bundle It is rotatably attached to the resin handle as a rotating shaft, or fixed to the tip end of the electric toothbrush drive shaft to constitute a radial toothbrush.

According to a eighth aspect of the invention, in the first aspect of the invention, the free end of the fiber bundle disposed on one side of the jig is disposed at a position that is approximately equal in length on both sides of the jig, and is supported by the compression jig of the jig. When melting, compressing and melting, the fiber bundles in the fixture will be melted, compressed and fused, and the cross-sectional area of the fiber bundle will be reduced. The melted fibers will be pressed and diffused, and the cross-sectional area of the fiber bundle at the free end. It is different from the cross-sectional area of the fiber bundle in the bearing fixture and spreads into a radial shape. At this time, before the fiber bundle is cooled and hardened, the free ends of the both ends of the fiber bundle are rotated from the approximate center position of the fiber bundle to the periphery, and the radial or spiral-shaped diffusion jig is rotated by pressing the free end. The fiber bundle causes the free-end fiber bundles on both sides to be deformed in a softened portion close to the fixture and the compression jig, and by diffusing the free-end fiber bundles in any direction and angle, a uniform and unbiased radial fiber bundle can be formed. Radial toothbrush.

According to a ninth aspect of the invention, the radial toothbrush produced by the first invention, the second invention, the third invention, the fourth invention, the fifth invention, the sixth invention, or the eighth invention is rotated in the axial direction at an approximate central position. , using a fixed cutter to trim, or a radial toothbrush fixed at an approximate center position, using a rotary cutter to trim the tip end of the free end fiber bundle, thereby forming a hemispherical shape (champed mushroom), Any shape such as a spherical shape or a shaped dome shape, and the shaping blade of the fixed cutter or the rotary cutter is formed into a wave shape, whereby the free end side of the fiber bundle can be trimmed to have a hemispherical shape ( The surface shape of the radial toothbrush such as a mushroom-like shape, a spherical shape, or a shaped dome shape is a zigzag cross section.

According to a tenth aspect of the invention, the same jig and the compression jig incorporating the ultrasonic fused speaker are melted, compressed, and fused by the same jig and the heat-resistant test fixture. And compressing the jig to melt, compress and fuse the fiber bundle to form a radially-expanded free-end fiber bundle, which is capable of forming a final purpose fiber bundle arrangement direction and a distribution density direction, and blowing hot air, cold air or normal temperature gas, The free end fiber bundle is diffused into any direction and angle, whereby a radial toothbrush having uniform, unbiased radial fibers can be formed.

According to a thirteenth aspect of the invention, in the axial direction of the fiber bundle of the both sides of the radial toothbrush according to the eighth aspect of the invention, or the fiber bundle perpendicular to the axial direction is substantially at a central position, the shaft is inserted into the through hole to fix or rotate the shaft. The shaft is supported by a shaft or fixed to the electric toothbrush drive shaft to form a radial toothbrush; or the shape of the inner surface of the opening of the fixture is maintained in a cylindrical shape or a cylindrical shape, whereby the cylindrical portion is regarded as The shaft is fixedly or rotatably mounted to the shaft or fixed to the electric toothbrush drive shaft to form a radial toothbrush.

According to a twelfth aspect of the invention, the outer side of the long fiber bundle of the first, third, fourth, fifth, and sixth inventions is bundled into a fiber bundle of an arbitrary thickness by a resin film such as a heat-shrinkable web film, and is fixed and integrated. The compression jig is used to compress the fiber bundle, and is melted and melted into a knot by a heater, an ultrasonic fuser, or a microwave, and then the resin film is peeled off and the non-melted portion of the fiber is opened. At the same time, the fibers are cut at or near the interval of the respective fused portions, whereby the non-melted portion fibers of the fiber bundle are diffused into a radial or spherical shape to form a radial toothbrush.

When the radial toothbrush manufacturing method and characteristic structure of the present invention are used, the following effects can be obtained. According to the first aspect of the invention, the long fibers are cut into short fibers, and a plurality of short fibers are bundled to form a fiber bundle, and the longitudinal end of the fiber bundle is melted, compressed, and fused, whereby the fibers are compressed and deformed. The interfiber space of the fiber bundle disappears, and at the same time, the melted short fiber is compressed and deformed, and is pressed and diffused to the outside of the jig, and the cross-sectional area of the fiber bundle is reduced, and the fusion is integrated. At this time, there is a difference between the cross-sectional area of the fiber bundle at the end of the melted, compressed, and melted, and the cross-sectional area of the fiber bundle at the free end. Therefore, the fiber bundle at the free end diffuses into a radial shape, and the free end is radially dispersed. And one of the end sides of the melted, compressed, and melted fuses are completely melted and integrated into one. Near the end side of the melted, compressed, and fused one, the melt fiber bundle is pushed and diffused by compression, whereby it can be easily deformed, so that it does not break at this portion.

When the above configuration is used, instead of using a conventional metal flat wire or a round wire or the like, a plurality of hairs are implanted on the resin, and the fibers are integrally formed by melting, compressing, and melting the bundle of the fibers to form a fiber of the entire toothbrush. Since the bundle is composed only of fibers, it is possible to efficiently form bristles of high density and which are expanded into a hemispherical shape, and to increase the number of short fibers constituting the fiber bundle or to make a difference in the cross-sectional area of the fibers constituting the fiber bundle. Thereby, the density of the formed rotating toothbrush can be made very high.

Further, at this time, the cross-sectional area of the fiber constituting the fiber bundle is used, and the difference between the one end side and the free end of the melted, compressed, and melted portion is rough, whereby it is assumed to be melted, compressed, and fused. When the one end side is composed of fibers having a small cross-sectional area, the degree of development of the free end is increased by the difference in the sectional area of the expanded fiber bundle. Similarly, the fiber constituting the fiber bundle is not a single-thickness object, and is not an object having a free end and a cross-sectional area on one end side, for example, when the cross-sectional area of the one end side and the free end side of the fiber bundle is different depending on the location. In the case of the fiber, the cross-sectional area is reduced by the disappearance of the fiber gap between the one end side and the fiber deformation, and the difference between the cross-sectional area of the fiber bundle at one end side and the cross-sectional area of the fiber bundle at the free end is increased as a whole of the fiber bundle. The free end side of the melt, compression and fusion will expand at a wide angle.

Moreover, by imparting a bevel shape to the side of the free end of the fiber bundle that is subjected to the jig and the compression jig, in particular, the fiber that is subjected to the melting, compression, and fusion and has a reduced cross-sectional area to the jig and the edge of the compression jig is prevented. At the same time, the free end can spread more smoothly and smoothly. The shape of the edge of the opening of the jig and the compression jig is such that the entire shape of the radial toothbrush and the shape of the end side of the fusion tooth can be freely formed, and the diameter of the opening is increased by a bevel, and the free end of the fiber bundle can be Diffusion into a wider-angle semi-dome shape, when the shape of the free end side of the fiber bundle that bears the jig is expanded into a fan shape, the free end is diffused into the shape of a ginkgo leaf, and when the fan shape is combined in a right-angled cross direction, the free end The longitudinal direction of the fiber bundle is such that the free ends of the fiber bundles are arranged in a cross shape, and the shape of the other openings and the edge portions of the openings can be imparted to the free end side. At this time, by providing the holding shape or the sleeve shape preventing rotation to the inner circumference of the fusion-integrated opening portion on one end side, it is possible to provide an attachment mechanism for efficiently attaching the radial toothbrush to the handle or the electric tool drive shaft.

According to the first aspect of the invention, at the end of the plate-shaped receiving jig having the same thickness as the length of the fiber bundle fusion and the fusion portion, one end of the fiber bundle which is estimated to be deformed by compression fusion is inserted. The compression jig that is attached to the open end of the opening of the jig is compressed in the direction of the fiber bundle, and at the same time, the ultrasonic wave-filled speaker mounted inside the compression jig emits ultrasonic waves, whereby the fiber bundle is melted. Melting, compressing, and melting have a difference from the cross-sectional area of the fiber bundle at the free end, so the fiber bundle at the free end diffuses into a radial shape. At this time, the fiber bundle diameter is relatively large, and when the fiber bundle cannot be sufficiently melted and melted by the method of resin thermal friction, it is preferable to heat the fixture body by various heat sources such as an electric heater or electromagnetic induction. In this case, in the actual manufacturing step, it is of course preferable to carry out the Teflon processing on the surface of the jig in order to make the mold release property of the jig and the resin fiber good, and it is easy to integrate the fiber bundle after the forming. take out. Further, in order to control the shape of the fiber to be unfolded, to prevent detachment, and to attach the toothbrush itself to the device by inserting a resin or the like, the annular metal is placed around the melted and fused portion of the fiber bundle, and melted and melted. When the fuse is melted or melted, a stronger toothbrush can be made when riveting is used. The ring-shaped metal to be riveted is riveted while heating the metal ring itself for the purpose of the processing step for the purpose of the work, or is riveted at a normal temperature. When a metal ring is attached for the purpose of attaching the toothbrush body to a resin or the like, it is of course necessary to form the ring end into a corresponding shape in advance.

When the fiber bundle forming step is carried out, as shown in the second invention, in the step of melting, compressing, and melting the fiber bundle, the portion of the fiber bundle that is adjacent to the jig is pressed and expanded by compression, so that it can be easily In the state of deformation, at this time, the free end of the fiber bundle is crimped while rotating the plate-shaped or scroll-shaped diffusion jig, whereby the fiber bundle at the free end is brought to the periphery from the approximate center position, and the tip end portion of the fiber bundle is uniformly radiated. Diffusion, so that the surface density of the fiber bundle at the free end side can be freely adjusted, or the direction of the fiber bundle at the free end with respect to the longitudinal axis can be formed at any angle, not only in one direction, but also in any direction from 180 degrees. Contact with a clean sweeping object provides a toothbrush with a uniform density. Of course, the fiber bending angle of the root of the fiber bundle is, of course, freely changed by the position of the diffusion jig contacting the fiber as the fiber constituting the fiber bundle is elastic.

When the third invention is used, in the first invention and the second invention, when the actual use of the fiber bundle is uniformly arranged to form a radial radial toothbrush, the contact angle or the number of contacts of the cleaning target portion is partially localized. Differences caused by consumption or recession, or excessive deformation due to contact stress' cannot reach the target site smoothly, but considering the shape of the cleaning object, the contact angle of the radial toothbrush, or the moving direction when the radial toothbrush is completed, when When the fiber bundle fiber is formed by forming a fiber-shaped toothbrush and the fiber bundle fiber is made of a single material resin, when the diameter of the cross-sectional area of the bristles is locally changed, or a resin having a local mechanical property is partially formed, In a radial toothbrush, because of the location, the waist or the soft part can be imparted, and the waist portion can be easily mechanically deformed, and the toothbrush portion is deliberately become a depressed portion. At the same time, the portion contacting the tooth uses a hard fiber to contact the flesh. Partially softer fibers are used, which will increase the comfort of use by rubbing the radial toothbrush fibers Frequently equipped with high wear-resistant fibers, it provides a high-durability radial toothbrush that provides non-destructive comfort. Further, when the fibers having the waist portion are disposed at the center of the longitudinal axis of the toothbrush, and the fibers having the waist portion are disposed, and the fibers disposed at the center portion and having the waist portion are inserted into the interdental portions, the guide can be guided. The effect can be surely inserted, and when the radial toothbrush is inserted into the instrument for electric rotation, the toothbrush can be prevented from being broken and collapsed by the rotational frictional resistance of the surrounding toothbrush. At this time, when the fiber tip provided in the center portion and having the waist portion is previously processed into a circular shape, it is very safe even if the impact of the tooth or the like is not injured. Further, by changing the arrangement position of the fibers or the color of the fibers, by color-encrypting, it is possible to easily produce not only the types of the toothbrush but also the products which are visually very beautiful. The color-coded fiber arrangement position may be arranged in concentric, radial or random dyeing.

According to the fourth aspect of the invention, in the first aspect of the invention, the fiber bundle composed of the fibers made of a single material is formed of a core-sheath structure thermoplastic resin having a different melting point in the core portion and the sheath portion. When a radial toothbrush is produced, when the one end side is melted, compressed, and fused, when the melting point of the sheath portion is lower than that of the core portion, the thermoplastic resin fiber of the core portion maintains the fiber cross-sectional shape while being compressed and fused. Only the outer sheath portion is uniformly melted and integrated. In this case, since the cross-sectional shape of one fiber after the fusion, compression, and fusion molding maintains the shape of the core, the fibers constituting the fiber bundle can maintain a uniform cross-sectional shape without local differences, and By controlling the melting temperature, the thermoplastic resin of the core is also moderately softened, and can be deformed while maintaining the cross-sectional shape. Further, when the melting points of the core portion and the sheath portion are largely different, it is necessary to minimize the influence of the heating on the physical properties of the core thermoplastic resin.

When the fifth invention is used, the fibers constituting the fiber bundle are crimped into a spiral shape or a wave shape. Therefore, by melting, compressing, and melting one end side, the fibers on the free side of the other end interfere with each other and rebound. Just as humans burned their hair and spread out a lot. Further, in particular, when a fiber having a large degree of crimping is used, even if the compression of the cross-sectional area of the fiber due to the lateral melting of the fiber bundle is not added, the fibers at one end of the fiber bundle can be densely bundled, by A small gap of the aforementioned fiber bundle is melted and melted, and sufficient diffusion can be obtained. In this case, the melting range of the fiber bundle can be minimized, so that the mass production speed can be increased and the production efficiency can be improved.

In the sixth aspect of the invention, the fiber bundle constituting the radial toothbrush is composed of a nonwoven fabric of a thermoplastic resin or a porous ribbon, and therefore, compared with the fibers constituting the fiber bundles of the first invention and the second invention, The compressibility is high, and the amount of deformation due to compression is large. Therefore, the difference between the melting, compressing, and melting portions and the free end cross-sectional area becomes larger, so the free end expands larger and at the same time provides a kind of A radial toothbrush with a higher density of free ends. When a non-woven fabric is used, the abrasive coating is contained by the binder, and a radial toothbrush having a good polishing effect can be provided. Further, when a porous ribbon is used, the pores of the material can exert mechanical friction and clean the object. The dirt adhering to the surface, therefore, can provide a radial toothbrush with a good cleaning effect.

When the seventh invention is used, the first invention, the second invention, the third invention, the fourth invention, the fifth invention, or the sixth invention are freely reproduced in a hemispherical shape (sweet mushroom shape), a spherical shape, or an alien shape. The fixed end side of the radial toothbrush having a dome shape, a conical shape, a cylindrical shape, or the like is integrally attached to the resin handle by fusion or the like, whereby the radial toothbrush is inserted into the oral cavity to reach the target site, and Implement cleaning. Further, when the fiber bundle is melted, compressed, and fused, when the fixing member 47 made of a fixed or rotatable metal or the like is inserted and molded, the toothbrush integrated with the fixing member can be easily produced. The fixing member 47 is capable of detachably attaching the radial toothbrush. Therefore, when the radial toothbrush detachably attached to the fixing member 47 is fixed to the rotating or vibrating electric toothbrush driving shaft tip, A toothbrush that is shaped to clean the area for more effective brushing. Further, the fixed end side fiber bundle in which the radial toothbrush is integrated is regarded as a rotation axis, or is inserted perpendicularly or at an arbitrary angle with respect to the longitudinal axis direction, and when mounted to a resin handle, A radial toothbrush that can be rotated freely in any direction. By arbitrarily adjusting the rotational resistance of the toothbrush mounting shaft, when performing oral cleaning, the radial toothbrush corresponding to the force of pressing the tooth surface or the tooth and the radiation caused by the vertical movement relative to the rotating shaft relative to the handle The stress generated by the rotation of the toothbrush, and moderate rotation, can not only play the role of the user to take a moderate cleaning direction, but also can clean the tooth surface or the flesh with appropriate pressure, so it will not hurt. In addition to the flesh, the fresh toothbrush surface is often brought into contact with the cleaning portion by rotation, so that the cleaning efficiency can be improved.

According to the eighth aspect of the invention, in the first aspect of the invention, the free end of the fiber bundle disposed on one side of the jig is placed on the both sides of the opening of the jig, and is approximately equal in length, and is subjected to the same treatment as in the first invention. a compression fixture with a supersonic fused loudspeaker for melting, compressing, and melting, or a heated fixture, a compression fixture, to melt, compress, and fuse the fiber bundle The cross-sectional area of the fiber bundle inside will be reduced, and the melted fibers will be pushed out to the sides of the jig. Thereby, the both ends of the free end fiber bundles are radially spread on both sides of the jig in the same manner as in the first invention. In other words, in the first aspect of the invention, the fiber bundle which is diffused into a hemispherical dome shape on one side can be reproduced on both sides of the jig, so that it is possible to form a bristles in a spherical shape centering on the melting, compression and fusion portions. Spherical toothbrush. At this time, and before the fiber bundle is cooled and hardened, the free ends of the both ends of the fiber bundle are rotated from the approximate center position of the fiber bundle to the periphery, and the radial or scroll-shaped diffusion jig is rotated to control the free-end fibers on both sides. The deformation of the softened part near the jig and the compression jig can be used to diffuse the free end fiber bundle into any direction and angle, and can impart an arbitrary bristle density according to the purpose or part of use, and can form a uniform whole. Unbiased, a radial toothbrush with uniform radial bristles.

When the ninth invention is used, the approximate center positions of the melted, compressed, and fused portions of the radial toothbrush produced by the first invention, the second invention, the third invention, the fourth invention, the fifth invention, and the sixth invention are maintained. The vertical axis direction is rotated as a center of rotation, or a fixed cutter having a certain angle to the aforementioned rotating shaft is crimped, or a rotary cutter having a desired shape of the inner surface is used to trim the free end fiber. By the tip end of the bundle, it is possible to form an arbitrary shape corresponding to the target cleaning portion such as a hemispherical shape (sweet mushroom shape), a spherical shape, a cannonball shape, a shaped dome shape, a conical shape, or a cylindrical shape. The thus formed radiation toothbrush having a degree of cleaning ability of 180 degrees can reproduce a shape of a toothbrush which can clean a groove, a cavity or a peripheral pocket or an interdental drum type void, which is not accessible to a general toothbrush.

Further, even in the case of the article having the radial toothbrush on both sides as in the eighth invention, when the above-described fixed cutter or rotary cutter is used to trim the radial toothbrushes on both sides, the mushroom-shaped or shaped circle is made. Various shapes such as a top shape, a conical shape, and a cylindrical shape are provided on both sides, and a radial toothbrush covered with a bristles can be provided, and a toothbrush having a high cleaning performance such as a gap between the teeth or a split groove can be provided. In particular, when the radial toothbrushes on both sides are symmetrically trimmed into a hemispherical shape, a radial toothbrush having a true spherical shape can be formed.

When the tenth invention is used, the second invention and the eighth invention are those in which the bristles are evenly arranged by using the diffusion jig. However, when the fiber bundle is melted, compressed, and fused, the hot air and cold air are blown. Or a normal temperature gas, the free end fiber bundle diffusion heat is set to an arbitrary direction and angle to form a desired fiber bundle arrangement direction and arrangement density. The above steps are carried out from the fiber bundle to the respective stages after the melting, and the blowing treatment is performed at an optimum timing, whereby the shape of the fiber bundle at the free end and the radiation are formed by blowing the needle at any point. Any part of the toothbrush can be bent into bristles not only in straight hair. Further, when the cold air or the normal temperature gas is used, the cooling time can be shortened as compared with the natural cooling after the molten fiber bundle is cooled, so that the production efficiency of the radial toothbrush can be improved.

When the eleventh invention is used, when the melting, compressing, and fused portions described in the eighth invention are used as the center, the fiber bundles of the spherical toothbrush having the spherical bristles in total are approximately centered at the center of the fiber bundle to be fused or attached. The resin handle is applied, whereby a spherical toothbrush having a symmetric radial toothbrush on both sides is inserted into the oral cavity to be cleaned by reaching the intended site. In the same way, when the rotational end of the radial toothbrush with the symmetrical radial toothbrush on both sides is fixed, the rotating or vibrating electric toothbrush drives the shaft tip, and the toothbrush is fully inserted at 360 degrees with the bristles. The bristles are in contact with the cleaning area due to the angle or the angle of the holding, so that effective cleaning can be performed frequently. Further, when the integrated melt-fixing portion of the toothbrush is attached to the resin handle as a shaft, the handle-shaped radial toothbrush which is rotatable in all directions can be formed with the angle of attachment of the handle. The rotational resistance of the toothbrush and the bearing can be arbitrarily adjusted, whereby the radial toothbrush that imparts rotational resistance with an appropriate pressure when the handle is cleaned by the handle, is rotated at the correct pressure to contact the tooth surface or the flesh, and is only operated correctly. When cleaning the direction of motion, the radial toothbrush will rotate properly with the stress on the tooth surface or the tooth, and it can often be cleaned while massaging the tooth surface or the flesh with appropriate pressure. Thereby, not only can the tooth damage be prevented, but also the function of guiding the correct brushing method can be exerted, and the cleaning portion can be often contacted with the fresh toothbrush surface by rotation, so that the cleaning efficiency of the toothbrush can be effectively improved.

Further, the radial toothbrush having the entire bristles can be attached to the electric toothbrush at approximately the center position, and the cleaning operation can be efficiently performed by imparting only the rotational motion, the reverse rotational motion, the sound wave, and the ultrasonic vibration. Not only the cleaning in the mouth, but also the comprehensive radial toothbrush with unrestricted contact direction on the surface of the cleaning object, especially for objects with concave and convex parts. When the example is used, when looking at the two-dimensional image of the mirror When washing your face and massaging your face, there is a bristle part that often touches the surface of the skin vertically. Therefore, by simply touching the muscles with a proper pressure by the brush, you can simply move the brush while rubbing the target space, and the tip of the bristle can invade the pores. Improve the cleaning ability by fine unevenness. In this case, the electric toothbrush can of course improve the effect when vibration, sound waves or ultrasonic waves are applied to the spherical radial toothbrush.

However, the fiber system used in the present invention is very slender and is very difficult to handle in the production step. However, as an example of the avoidance method, when the individual radial toothbrush is formed, the small end of the fiber bundle is temporarily fused, whereby When the radial toothbrush is prevented from being easily treated, or when the radial toothbrush is continuously produced, as shown in the twelfth invention, the outer side of the long fiber bundle described in the first, third, fourth, fifth, and sixth inventions has heat shrinkability. A resin film such as a mesh film is tightly bundled into a bundle of fibers having an arbitrary thickness, and is integrated and integrated, whereby it can be handled as a single piece, which is very convenient. When a compression jig is used to compress a fiber bundle which is monolithically integrated by the aforementioned web cover film, one end is cut off, and a heat source such as a heater or a supersonic fusion machine or microwave is used to melt and fuse. In the form of a knot, the web is covered with a web that is not fused to the other fiber bundle at the other end, and the fiber is opened, whereby a radial toothbrush can be formed. Further, although the fiber bundle cutting position covered by the mesh film is formed into a node portion, it can be set to any position at both ends of the compression, fusion, and fusion portions, and the fiber bundles which are not melted at both ends by the peeling are covered. The web is made of a film and the fiber is opened, and the spherical toothbrush is simply mass-produced.

In this way, when the present invention is used, the radial toothbrush can be manufactured in various forms for the purpose of use, not only for the dental cavity forming article, but also for the cosmetic applicator or face brush, or in the general industry. In addition, it can also be used for cleaning abrasive tools, and its use is not only quite extensive, but also, when the spherical bristles are to be reproduced, the density of the bristles of the prior hair-brushing toothbrush is much higher.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 14 are views showing one embodiment of the present invention. In the drawings, the same reference numerals denote the same items, and the basic configuration is the same as the previous items shown in the drawings. However, the figure illustrates the basic features of the radial toothbrush. The fiber bundle is compressed and deformed by melting, compressing, and melting at one end side in the longitudinal direction of the fiber bundle, so that the fibers between the fiber bundle fibers disappear and melt and integrate. At this time, the free end fiber bundle is radially formed by the difference between the cross-sectional area of the fiber bundle at the end of the melted, compressed, and melted limb and the cross-sectional area of the fiber bundle at the free end. As shown in Fig. 1, a nylon 612 long fiber having a diameter of about 0.1 to 0.2 mm is cut into a predetermined length by a cutter, for example, when it is used for a toothbrush in the oral cavity, it is cut into 10 mm. The short fibers of the right and left are in the shape of a pair of teeth, and the fiber bundle 1 is formed by bundling about 300 to 1000 in accordance with the density of the intended toothbrush. The obtained fiber bundle 1 is inserted up and down in the longitudinal direction, and is inserted into a predetermined position in the jig opening portion 6 formed by the jig 3 and the compression jig 4, and at the same time, a compression jig that slides in parallel by the slide guide 5 is used. 4 tightly hold the fiber bundle 1. When the short fiber supply mechanism in this step is implemented by an automatic machine, the plurality of long fibers fed by the pre-bundle can be cut into short fibers of a predetermined length for the purpose of inserting the jig to form a short fiber. Fiber bundle 1. Here, the ultrasonic vibration element 31 is embedded in the center portion, and the compression jig 4 including the slide guide 5 is moved in parallel with the direction of the jig 3 by the restriction of the slide guide 5. The ultrasonic vibration element 31 vibrates, so that the fiber bundle 1 is melted, compressed, and fused to the final destination shape by the jig 3 and the compression jig 4. By the above-mentioned series of steps, the fiber bundle 1 in the opening portion 6 of the jig formed by the jig 3 and the compression jig 4 is reduced in cross-sectional area, but the softened fiber is further flowed out to bear the jig 3 and The outer side of the jig 4 is compressed, and the cross-sectional area of the fiber bundle is reduced, and a difference is made between the cross-sectional area of the fiber bundle at one end side and the free end of the melted, compressed, and melted, as shown in Fig. 2, the free end fiber bundle system Radial spread. When a large amount of fibers are compressed into a fiber bundle in order to increase the fiber density of the radial toothbrush, the above-described compression melting and melting step is carried out in two steps. In other words, in the first compression-melting step, elliptical molding is performed, and in the state in which the shape is maintained, the second compression fusion is performed from the first compression fusion direction in the first straight direction. In the melting industry, the fiber bundle is not deformed by extrusion and is concentric with respect to the center of the fiber bundle. The fiber bundle diffusion spread angle in these compression fusion melting steps can be adjusted by controlling the vibration time of the ultrasonic vibration element 31 and the timing of compressing the compression time of the jig 4, at this time, the fiber extruded by compression Since the beam system maintains fluidity, it is in a state of being easily deformed, and therefore, there is no breakage in the transition portion. Moreover, the diffusion of the free end is caused by the difference in the sectional area of the fiber between the one end side and the free end. Therefore, when the free end uses the sectional area ratio to be larger than the one end side of the pre-melting, compressing and melting, the free The degree of expansion of the end will be greater, and when the opposite material is used, the free end will expand less. At this time, when the fiber bundle is melted and melted, the electric heater is used, or various heat sources such as electromagnetic induction are used to heat the fixture body, the fiber bundle is punched in a state in which the fixture body is heated in advance, and the fiber bundle is bundled. The melting sequence is adjusted by controlling the compression speed, the applied pressure, and the heating temperature. The fibers that are in direct contact with the jig that is heated at this time are melted. Therefore, in order to separate the jig from the resin fiber, the Teflon resin processing or the like is applied to the surface of the jig, and the fiber is integrated after forming. The bundle is easy to remove. Further, in a state in which the metal ring is placed around the compressed portion of the fiber bundle, the metal ring is squeezed and compressed by the stress of the fiber bundle to minimize the recombination of the compressed portion, and at the same time, the compression can be performed. Part of the shape remains stronger.

As described above, the manner in which the self-diffusing radial toothbrush is unfolded can be controlled by melting, compressing, and melting the shape of the free end opening portion on one end side as shown in Fig. 3. As shown in the example, in the case where the opening portion at the time of final compression is shaped into a cross-shaped object such as A, when the fiber bundle fiber inserted into the jig that is opened by C is melted, compressed, and fused, such as D As shown, a radial toothbrush in which the fibers are unfolded into a cross-shaped sector can be obtained when viewed from the longitudinal direction. At this time, when the shape of the opening portion is such as B, the fiber bundle is expanded into a fan shape, and as shown by A and B, the fiber bundle is brought close to the fiber of the jig by imparting a circular bevel shape to the opening direction of the fiber bundle. The smoothness spreads more smoothly, and at the same time, the strength of the fiber on one end side is prevented from being reduced and broken due to fusion and compression. Further, the opening portion 6 which is formed by the jig 3 and the compression jig 4 is different from the object which is closed on the opposite side to the free end of the example, and when a part or all of the opening is opened, the melted fiber is compressed and flows out. The outflow of the part will be reduced, and the amount of spread of the free end fiber bundle will also decrease.

According to the above manufacturing step, a radial toothbrush in which the free end is radially diffused can be formed. However, as shown in Fig. 4, the fiber bundle close to the portion of the jig 3 and the compression jig 4 is melted. Compressed and extruded into a deformable state. At this time, the plate-shaped or spiral-shaped diffusion excitation 32 is rotated and pressure-expanded to excite the rotating shaft 13, so that the surface density of the free end side fiber bundle can be freely adjusted, and at the same time, The direction of the free end fiber bundle with respect to the longitudinal axis direction is formed in an arbitrary direction so that the fiber bundle can be diffused radially from the free end to the periphery from the approximate center position of the fiber bundle. By the toothbrush diffusion mechanism caused by the diffusion excitation 32, the density of the brush of the radial toothbrush can be made uniform, or, conversely, a radial toothbrush having any density change can be formed, and the fiber bundle 1 can be formed. The application range of the constituent material for the fiber material having various mechanical properties is expanded, and at the same time, the vibration timing of the ultrasonic vibration element 31 and the subtle timing adjustment of the compression time by the compression jig 4 can be easily implemented.

Further, when the fiber bundle 1 is set to bear the jig opening portion 6 composed of the jig 3 and the compression jig 4, the fibers constituting the fiber bundle of the radial toothbrush are configured to have the estimated composition When the fiber portion of the radial toothbrush is composed of a resin having different mechanical properties, the hardness or color of the fiber constituting the radial toothbrush 7 can be changed in one radial toothbrush, and the purpose and use can be utilized for the purpose of use. The performance of the method.

Similarly, when the configuration of the fiber bundle 1 is constituted by a single material, it is constituted by either changing the sectional area diameter of the fiber or a spiral or wavy fiber bundle by crimping, whereby the free end side Each of the fibers will have the same effect in rebounding, and even if the fibers of the fiber bundle 1 are formed of a thermoplastic resin non-woven fabric or a porous ribbon having high compressibility, the density of the fiber bundle at the free end can be freely changed, and at the same time, A large spread angle. Further, when a thermoplastic resin non-woven fabric or a porous ribbon having high compressibility or a fiber having a large degree of crimping processing is used, since only the bundle of fibers is simply bundled, the free end can be fully spread and diffused, so that the fiber is eliminated. The cross-sectional area compression of the fiber caused by the lateral melting of the bundle can be sufficiently diffused by melting and melting the small bundle of the fiber bundle, thereby improving production efficiency.

By the above steps, the fibers of the fiber bundle 1 are arranged approximately radially to form the radial toothbrush 7. However, as shown in Fig. 5, when the toothbrush is the same as the general toothbrush, the longitudinal axis of the tooth is opposite from the lip side. When the cleaning operation is performed by abutting the tooth surface in a vertical direction and an appropriate pressure, the tip of the toothbrush is intentionally inserted into the tooth pocket without changing the handle, and the radially dispersed fiber automatically enters the tooth in the radial toothbrush. The cleaning operation is completed by the inside of the periodontal pocket 8 formed by the tooth supporting tissue 10. Further, when viewed from the cheek tongue surface, the form of the tooth portion 9 and the tooth supporting portion 10 (the shape of the edge tooth) is formed into a wave shape in which the arc is connected, and the cleaning operation is performed while sequentially pressing the teeth. At the time, the shape of the radial toothbrush 7 is similar to that of the tooth neck tooth, so that the inside of the tooth pocket 8 can be cleaned efficiently.

As shown in FIG. 6, the radial toothbrush 7 has the cylinder-type dressing cutter 11 having the blade 12 trimmed by the rotation axis 13 from the same direction as the longitudinal axis of the radial toothbrush 7. The shape of the cylindrical pressure cylinder type radial toothbrush 14 can be formed. By changing the shape of the cylinder type radial toothbrush 14 in various shapes, it is possible to form various shapes such as a hemispherical shape (shallow mushroom shape), a spherical shape, or a shaped dome shape in which the axis of rotation of the rotary shaft 13 is centered. Radial toothbrush. Such a representative trimmed radial toothbrush has a curved dressing cutter 15 having a blade edge 12 inclined with respect to the rotating shaft 13 as shown in Fig. 7, and is parallel to the longitudinal axis of the radial toothbrush 7. A method of trimming the rotating shaft 13 while rotating, thereby forming a projectile type radial toothbrush 16. In the above-described dressing method, although it is necessary to rotate in the opposite direction to the curved dressing cutter 15 of the radial toothbrush 7, it is also possible to reproduce the difference from the curved dressing cutter 15 shown in Fig. 6, and to fix the fixed side at the free end. It has a shape that maintains the shape. The shape of the shell-type radial toothbrush 16 is as shown in Fig. 9, which is very suitable for cleaning the two adjacent teeth by forming the interdental drum-shaped void 17 on the flesh side adjacent to the teeth, and at the same time, when in the interdental portion When the shaft fiber 36 is guided by the cannonball type radial toothbrush 16 on the cheek side or the lingual side, the interdental portion 17 can be easily inserted. In the manufacturing method, an object obtained by previously making a small bundle of the bundle of the fiber bundle is opened, and a hole is formed in the center or at any position of the fiber bundle, and the fiber as the guide shaft is inserted into the hole, and is melted and compressed from the periphery at any position of the fiber bundle. By melting, it is possible to form a radial toothbrush having a guide shaft at the center. In this case, the guide shaft can also be compressed and fixed only by the metal ring.

Further, particularly when the riveted metal ring holding portion 38 of the rivet metal ring 37 is attached to the tip end of the electric appliance or the like, the guide shaft fiber 36 prevents the rotating projectile type radial toothbrush 16 from being eccentrically moved and can be comfortably cleaned. In the operation, only the interdental portion 17 can be inserted, and the interdental drum-shaped void 17 formed by the two-tooth and inter-tooth inter-nips can be directly inserted into the tooth line which is difficult to clean, and can also be inserted only between the teeth. The toothbrush is cleaned in the tooth pocket 8 in the interdental drum-shaped recess 17, and the cleaning of the portion is automatically performed. Further, when the projectile-type radial toothbrush 16 is mounted on the electric toothbrush or the like that automatically reverses the movement, the interdental portion cleaning can be performed more efficiently.

The various radial toothbrushes 7 formed in the above-described respective steps are attached to the handle 21 as shown in Fig. 10, and can be easily reached to the intended position. The article shown in the embodiment is capable of smoothly excluding the lips and cheek ribs without any resistance to rotation, front and rear or longitudinal movement when inserted into the oral cavity, and the article of the hemispherical lip guide 20 can be cleanly mounted. Further, although the handle 21 (lip guide 20) and the method of attaching the radial toothbrush 7 may be of a fixed type, the fiber bundle of the radial toothbrush 7 may be rotatably mounted with the longitudinal axis direction as a rotation axis. At the time of cleaning, the radial toothbrush 7 automatically rotates and the fresh toothbrush surface can frequently contact the cleaning portion, and a rubber O-ring or permanent magnet is used on the rotating shaft that is rotatably mounted. When a certain degree of rotational resistance is given to the radial toothbrush 7 when rotating, the object of the fixed radial toothbrush function is often exerted, and the excessive pressure generated by the incorrect cleaning method can be dispersed and removed by automatic rotation because often It can contact the tissue with ideal cleaning pressure, so it won't hurt the flesh. Similarly, the object shown in Fig. 11 is an article attached to the electric toothbrush rotating shaft 22 that generates the rotational motion, and the fiber bundle of the radial toothbrush 7 is attached to the longitudinal axis of the radial tooth axis as a rotating shaft. Thereby, when the rotating shaft 22 is rotated in a predetermined direction or in a reverse rotation motion, the radial toothbrush 7 in which the fiber bundle is approximately the central axis of the longitudinal axis as the rotating shaft can be efficiently cleaned by inheriting the above-described rotational motion. Others, even if it is mounted to an electric toothbrush driving portion that generates mechanical vibration, sound waves, or ultrasonic vibration, it can exhibit a high cleaning ability in conjunction with the shape of the radial toothbrush 7. Further, in particular, when a radial toothbrush is attached to a cleaning device that is electrically driven, it is necessary to be able to replace only the toothbrush portion from the viewpoint of cost. A method of easily forming the above-mentioned toothbrush, as shown in the radial toothbrush of Fig. 5, when the fixing member 47 made of a fixed or rotatable metal or the like is inserted and formed when the fiber bundle is melted, compressed, and fused, It is easy to produce a toothbrush that is integrated with the fixed part 47. At this time, the fiber bundle is melted in advance to produce a fiber bundle having no unevenness, and a hole is formed at a center or an arbitrary position in accordance with the longitudinal direction of the fiber bundle, and the fixing member 47 is set in the hole, by the self-fiber The bundle is compressed and melted, and a radial toothbrush having a fixed part can be formed without using an adhesive.

Fig. 12 is a cross-sectional view showing a method of molding a radial toothbrush in which a fiber bundle is melted, compressed, and melted integrally with respect to a center point, and a fiber bundle is spread and spread on both sides. The fiber bundle 1 is inserted into the circular bevel opening portion 6 at both sides of the jig 3 and the compression jig 4 having the same structure as the object shown in Fig. 1, as shown in Fig. 12, In the direction of the jig 3, while the compression jig in which the ultrasonic vibration element is housed is vibrated, the fiber bundle is melted, compressed, and fused, and the opening portion 6 is compressed, so that the fiber bundles on both sides are radially expanded. Central government integration. After the above steps, the compression jig 4 is moved to enlarge the opening portion 6, and when the elastic force of the fiber bundle 1 is utilized, the integrated portion is symmetric at the center point, and the radial toothbrush which spreads the fiber bundle on both sides is obtained. A slightly spherical toothbrush with a slightly spherical shape can be obtained. In these forming stages, the free end of the radial toothbrush on both sides is rotated from the approximate center position of the fiber bundle to the periphery, and the radial or spiral-shaped diffusion excitation 32 is rotated in the same manner as the object having the radial toothbrush on one side. The diffusion jig is formed by dispersing the free end fiber bundle in any direction and angle by deformation at a softened portion in the vicinity of the opening portion 6 which is formed by the jig 3 and the compression jig 4. A radial toothbrush having a uniform, unbiased radial fiber bundle.

The substantially spherical spherical radial toothbrush 29 thus formed, as shown in Fig. 14, when the integrated cylindrical portion is used as a shaft, the central portion is rotatably attached to the handle 21 with the support pin 28, thereby providing A toothbrush having a handle 21 that has a bristles throughout. The method of setting the rotating shaft and the fixed shaft is not only the object of the illustrated example, but also a hole can be formed in a portion that is integrated into an arbitrary shape. After the shaft is inserted into the hole, the hole is fixedly or rotatably supported, and the mounting is performed in each of the mounting holes. In the method, the rotational resistance can also be controlled by the friction or magnetic force of the rubber sleeve.

The foregoing toothbrush is an object that has bristles and rotates in a certain direction. Therefore, by rotating along the skin secant, the bristles that often meet perpendicularly with the object enter the pores, so that it can be used as an auxiliary device for washing the face. . Further, the spherical radial toothbrush 29 can exhibit a higher cleaning ability when mounted on various electric toothbrush drive shafts, similarly to the radial toothbrush.

Conversely, the diffusion mechanism of the fiber bundle 7 of the radial toothbrush 7 can diffuse the fiber bundle by blowing, as shown in Fig. 13 in addition to the diffusion jig of the diffusion excitation 32 or the like. The hot end, the cold air or the normal temperature gas is ejected by the gas nozzle 26 with respect to the free end fiber bundle which is automatically diffused and expanded by melting, compression and fusion, so that the final fiber bundle arrangement direction and the arrangement density can be formed. The control shutter 27 in the gas nozzle 26 moves to the g direction to control the blowing direction, and simultaneously moves the gas nozzle 26 to the a direction, and blows air from the center portion of the radial toothbrush toward the edge, thereby making the free end fiber bundle Diffusion into arbitrary density, angle, direction and shape to form a uniform and unbiased radial shape.

As described above, when a radial toothbrush of various shapes is produced, the fiber system used in the present invention is very fine, and in the production step, the handling thereof is very difficult, but in order to solve this problem, as shown in the fifteenth X-1, The heat-shrinkable mesh film 39 fixes and integrates the outer side of the long fiber bundle 1 into a fiber bundle of an arbitrary thickness, and the fiber bundle 1 integrated in a rod shape by the mesh film 39 is placed at any position by the compression jig 4 At the same time, it is melted and melted into a knot shape by a heat source such as a heater or a supersonic fusion machine or a microwave, and is sent to the g direction as indicated by X-2. As shown by X-3 and X-4, the knot-shaped fiber bundle compression-melting portion 43 which is sequentially produced is held by the chuck 40 in the a-3, a-2, and a-1 directions, and at the same time, The cutter 41 cuts one end, and at the same time, only the mesh film 39 is cut by the mesh film outer peripheral cutter 42 on the opposite side. As shown by X-5 and X-6, the web film 39 of the fiber bundle 1 which is covered by the chuck 40 at one end is fed into the net film cut line 45 in the d direction by the net film cutter 44 and peeled off as described above. The net film 39, whereby the non-fused portion of the fiber bundle is opened as shown by X-7, so in the X-8 step, when the chuck 40 is at b-1, b-2 and When the b-3 direction is open, the radial toothbrush 7 will fall, and a high-efficiency radial toothbrush can be formed. Further, when a spherical toothbrush having a radial toothbrush on both sides is formed, a mesh film cutter 44 is provided on both sides of the holding portion of the chuck 40, and similarly, on the net film cutter 44 device, the net is fed into the net. A set of film cutting lines 45 to the mesh film 39 on both sides of the chuck 40, and then peeling off the mesh film 39, can be made into a spherical toothbrush.

Using the above method, after the step of Fig. X-4, when the step shown in Fig. 16 is employed, a cannonball type radial toothbrush can be formed. As shown in Fig. 16 Y-1, the end of the chuck is cut, and the other end is cut by the net film outer peripheral cutter 42 to cut only the net film 39, thereby rotating as shown by Y-2. When the cannonball type radial toothbrush moves in the c direction and the net cover film 39 is cut and peeled from the tip end portion of the fiber bundle 1, the fiber bundle 1 is unfolded, and at the same time, the outer cover web film 39 is compressed and detached and opened, so that It is possible to form a radial toothbrush which is slowly deployed and conforms to the shape of the dressing cutter. As shown by Y-4, when the projectile-type dressing cutter 46 is returned in the d direction so that the collet 40 is opened in the directions b-1, b-2, and b-3, the cannonball type toothbrush 16 will fall.

Finally, as shown in Fig. 8, the radial toothbrush having the above-described outer shape is pressed to rotate the zigzag dressing cutter 30 in the b direction while continuing to move in the a direction while rotating in the e direction. In the case of the toothbrush, the shape of each of the radial toothbrushes is added, and the zigzag-like unevenness can be imparted to the surface, and the spherical shape of the sawtooth section or the surface profile such as a disk shape or a profiled cross section can be freely produced. Moreover, the melting, compressing and melting mechanism of the present invention is not limited to a device utilizing ultrasonic friction heat, and a heat source such as microwave or laser may be used, and the trimming form of the radial toothbrush and the integrated portion to be melted may be used. The shape is not limited to the above-described example of the drawings, and of course, the radial toothbrush can be appropriately changed in shape when the radial toothbrush of the present invention is attached to various instruments without departing from the gist of the present invention.
