Abstract

The method of producing bristle arrangements for brushes and the apparatus (1), the carrier plate (17) and the brush (60) fitted with such a carrier plate (17) make it possible to simplify the operation of producing bristle arrangements for brushes, inter alia, in that the clusters (5) of bristles, which are transported to the bristle-retaining plate (9) by way of the transporting apparatus (6) using a gas stream or air stream, are discharged electrostatically as they are being transported by way of the transporting apparatus (6), and therefore they can be transported more easily through the transporting apparatus (6), and in that they reduce the outlay required for the anchor-free fastening of clusters (5) of bristles in a carrier plate (17), since the carrier plate (17) has rear-side material protrusions (54), which are fused and then pressed into a cluster-fastening plane in order for clusters(5, 5a) of bristles which have been introduced into the perforations (24) of the carrier plate (17) to be straightforwardly connected in a form-fitting and/or force-fitting manner to the carrier plate (17) (Figure 3).

Description

Small carrier plate and brush, especially a toothbrush with a small carrier plate

The present invention is a method for making a brush, especially a brushing field of a toothbrush, which is taken out of a material containing a stock of brush filaments and gathered into a bundle of bristles, followed by a flow of gas or air. The guide bristles are passed through a bundle of containment means and a delivery device comprising a hollow conduit attached thereto and then placed in a bore of a retaining plate.

The present invention relates to a small carrier plate having a plurality of holes through which a small carrier plate passes, and a bundle of bristles composed of brush filaments can be inserted into the holes and can be fixed to the small carrier plate without a fixture.

The invention further relates to a brush, and more particularly to a toothbrush having a handle and a brush head, the brush head having a small carrier plate holder and a small carrier plate with a bundle of bristles secured therein.

The foregoing method can be carried out on a device for manufacturing a brush, in particular a toothbrush, a brushing field, the device having a material cartridge containing a stock of brush filaments, and at least one removal device for removing individual tufts of bristles from the bristles inventory And having a delivery device having a hollow catheter, bristles The bundle can be delivered by a gas stream or air stream through the delivery device to a bore of a holding plate.

The foregoing methods, small carrier plates, brushes, and devices for making the bristle field are known in various forms.

In a method and apparatus for manufacturing a bristle field known in the prior art, when a bundle of individual bristle filaments is fed through a conveyor using a gas stream or an air stream, the brush filament may be fed to the apparatus. A problem occurs in the section or station behind the conveyor.

It may happen, for example, that individual bristle filaments or even whole tufts of bristles are retained in the conveyor and cannot reach their destination. In particular, when the brush filament is a very fine brush filament, it is particularly difficult to reliably feed the brush filament via the conveying device.

Also in the small carrier plate and the brush equipped with such a small carrier plate as known in the prior art, the bristle bundle is fed to the small carrier plate according to a method as described above and on a device as described above, in a non-fixed manner It can cause problems when fixed.

A conventional small carrier plate and a toothbrush equipped with such a small carrier plate are, for example, required to feed the brush filaments gathered into a bundle of bristles into the holes of the small carrier plate, and to wrap the ends of the individual bristle bundles positioned in the holes in a material package The blister is shot and the bristles are fixed in the holes. It is also known that the bristle filaments are gathered in a bundled manner and have been melted to each other before being transported to a small carrier sheet where the tufts of bristles need to be placed.

Once the end of the melted bristle bundle reaches the small carrier plate, it enters The ends of the holes that enter the small carrier plate and are mutually melted are coated and ejected, so that the bristle bundles are fixed to the bundle holding plate.

The object of the invention is therefore to provide a small carrier plate and brush as defined above, in particular a toothbrush which allows the bristle field to be produced in an efficient and simple manner and thus allows an efficient and simple brush, in particular a toothbrush. , the manufacture.

In order to better understand the present invention, the technical field of making a bristle field and a brush will first be described in detail by way of a particularly advantageous embodiment of the invention for producing a bristle field that best represents the quality of the invention.

In the method defined above, in order to be able to manufacture the bristle field more efficiently and simply, and thus to manufacture the brush more efficiently and simply, especially the toothbrush, in particular, the bristle filaments constituting the bristle bundle are conveyed to the bundle by the conveying device. Static discharge when holding the board.

Particularly in the so-called chemically sharpened brush filament feed, since it is characterized by a particularly fine silk thickness, the conveying device is always blocked in the prior art prior art methods, and the reason is found to be the bristles constituting the bristle bundle. Electrostatic charging of silk. Due to the frictional effect on the brush filaments of the tufts during transport of the conveyor, whether via gas or air flow, whether through the material of the hollow conduit through which the tufts are transported, the tufts of bristles and the bundles contained therein The brush filament may be electrostatically charged, causing it to adhere to the components of the delivery device, in particular to the hollow catheter of the delivery device, and cannot be reliably Guide through the delivery device. In addition, there is even a danger that the brush filaments are strongly electrostatically charged during transport via the transport device such that they block the transport device, and preferably the flow of the brush filaments leading to the bundle retaining plate is reduced.

This disadvantage can be avoided by electrostatic discharge through the brush filament during transport. Finally, a method can be obtained which is particularly effective in feeding a particularly fine brush, that is to say such a chemical sharpener, to the bundle holding plate by means of a gas stream or an air stream for further processing.

For the reliable discharge of the tufts of bristles, it is particularly advantageous if the bristles constituting the bristles are electrostatically discharged during their transport via the bundle accommodating device of the transport device and/or as they are transported via the hollow conduit of the transport device to the bundle retaining plate.

In particular, the electrostatic discharge in the delivery of the brush filaments via the beam holding device prevents electrostatic charging of the brush filaments starting from one of its transport via the transport device.

An electrostatic discharge of an optional or additional brush filament that is delivered to the bundle retaining plate via the hollow conduit of the delivery device prevents the brush filament from rubbing against the inside of the hollow conduit and electrostatically charging and blocking the hollow conduit.

A particularly simple but equally reliable brush filament electrostatic discharge is that the brush filaments constituting the tuft of bristles are electrostatically discharged when transported via a transport device, in particular when transported via a beam holding device and/or via a hollow conduit to a bundle retaining plate. Ground.

For this purpose, the tufts of bristles can be transported to the bundle holding plate when they are transported via the transport device, in particular via the beam accommodating device and/or via the hollow conduit. At the time, it is at least guided through an electrical contact or a ground contact provided on the conveying device for electrostatic discharge and comes into contact with it. It should be noted that the at least one electrical contact or ground contact can be provided, for example, in the beam receiving device and/or also in the hollow conduit.

The brush filaments constituting the tufts in this way achieve a particularly simple but reliable electrostatic discharge. It should be pointed out here that the electrostatic discharge of the bristle filaments constituting the tuft of bristles in their transport via the transport device not only allows the release of the electrostatic charge accumulated on the bristles, but also allows the electrostatic charging of the bristles to be avoided, in particular due to electrostatic charging. The friction of the bristle filaments constituting the bristle bundle is generated when being conveyed by the conveying device.

In an embodiment of the method it can be provided that the bundle of bristles is placed directly into the aperture of a small carrier plate by the bundle retaining plate. In a particularly advantageous embodiment of the method, it is possible to provide, in particular by means of a compression rod, the bundle of bristles from a tapered funnel channel of a funnel plate into a hole in a small carrier plate. This practice can be significant because it would be extremely laborious to complete the compression density of the bristle bundles required for a high quality small carrier plate implant by a gas or air stream alone. In practice, the bundle of bristles to be fed is first forced through the funnel passage of the funnel plate to achieve the desired density in a relatively simple manner, particularly when a compression rod is used.

In order to fix the bristle bundle to the small carrier plate in a non-fixing manner, the material protruding from the rear side and the rear side of the small carrier plate away from the bristle bundle can be arranged to be heated and melted at a welding station, and melted. Material The raised melt is pressed into one of the fixed faces of the bundle of bristles so that the melt flows in, especially from the rear side of the small carrier plate, between the ends of the bundle of bristles, and/or between the ends of the ends of the bundle of bristles, after which It can be hardened and connected to the bundle of bristles and small carrier plates. Thus, the bristle bundle can be fixed to the small carrier plate in a form-fitting and/or force-fitting manner because the melt is pressed to the tuft fixing surface and can be similarly fitted to the bristle bundle end.

In this way, a particularly simple method can be produced which secures the tufts of bristles in a small carrier plate without the need for a fixture.

Advantageously, the material bulge on the small carrier plate is heated, melted by at least one melting rod, and pressed to a fixed surface of the bristles to secure the bristles to the small carrier plate.

The advantages of the method are particularly useful when a bundle of bristles composed of chemically sharpened brush filaments is fed to the bundle retaining plate. This is also known as the chemically tapered wire-CTF's brush which is characterized by its particularly slender, free-to-use wire end, which has heretofore enabled such a filament to be flowed by a conveying device by gas or air flow. The feeding is very difficult, for which reason the particularly fine brush filaments are electrostatically charged in this case and thus cause uneconomical.

In a further embodiment of the method it can be provided that the bristle filaments are fed to a transfer station in a wire reel which is wrapped by a particularly elastic and/or airtight sheath. The wire tray fed to the transfer station can then be sucked by at least one of the suction jaws assigned to the transfer station, and the at least one suction claw contacts and sucks the free upper side of the wire tray, whereby the needle is particularly flexible And/or airtight bundles The longitudinal axis of the brush filament is drawn inwardly in the direction of the longitudinal center axis at right angles to the upper side of the wire disc, whereby the brush filament of the wire tray sucked by the yarn can be stabilized. After suction, the wire disc can be handed over to the de-station station at one of the rear stations of the transfer station by at least one suction claw. The bundle of wire spools can be opened and removed in addition to the station, after which the filaments released by the bundle can be fed to one or the preceding material, preferably for automated feeding.

It is pointed out here that the wire disc of the chemically sharpened brush has an elastic and/or airtight sheath, as previously described in DE 10 2013 003 249, the document relates to a method for producing such a wire .

The mode of action of the aforementioned removal station is described, for example, in the German patent application DE 10 2014 109 320.

Advantageously, the wire disc is subjected to a spin finish having an antistatic additive of CFT's which additionally reduces the tendency of the brush filament to electrostatically charge during transport.

In a further advantageous embodiment of the aforementioned method, it can be provided that the wire feed is fed to the transfer station, in particular at least one of the load-bearing surfaces of the feed station, which is preferably designed as a conveyor belt, at least to the transfer station. a claw.

This approach further enhances the efficiency and automation of the aforementioned methods.

The method can be further simplified for a person familiar with the implementation of the method in that the wire disc is individually and/or delivered at the feed station, in particular at least one bearing surface which is preferably designed as a conveyor belt. Inside the container Maintaining, and if desired, manual, preferably taken directly from the delivery container, is moved to at least one of the load-bearing surfaces, but particularly transverse to the direction of transport of the at least one load-bearing surface. Thus, those skilled in the art to carry out the invention can prepare a certain number of delivery containers with a wire disc placed on the loading surface of the feed station designed as a conveyor belt, if desired, that is, when the wire has been placed on the loading surface of the feed station. The disc can be replenished when it is used up by the subsequent stations. Depending on the number of spools on the load-bearing surface and depending on the processing time, ie the time required to process a single disc at each subsequent station, the person familiar with the method has sufficient time to perform other tasks, taking care of the feed only at regular intervals. Station, add more wire trays, so that the rest of the automated manufacturing process can be left unaffected.

The object of the invention is characterized in that the small carrier plate as defined above is characterized by the first item of the patent application and, in particular, by a small carrier plate having a plurality of material projections on the side of the bristle bundle which is remote from the insertion opening. As a result, the material protrusion can be melted and can be pressed into a bundle of fixing faces for fixing the bundle of bristles to the small carrier plate.

One such small carrier plate allows the tufts of bristles to be secured in a non-fixative manner on a small carrier plate without the need to weld the bundle of bristles that need to be secured in the small carrier plate to each other prior to feeding to the small carrier plate. The small carrier plate of the invention thus supports the execution of the aforementioned method in a particularly advantageous manner and practice.

In one embodiment of the small carrier plate, it can be provided that the tufts of bristles that can be placed or placed in the holes are formed by sharpened brush filaments, in particular by chemically sharpened brush filaments. This bristles at least after it is fixed to the small carrier plate The bundle can form a brushed field of sharpened brush filaments, in particular a brushed field of chemically sharpened brush filaments.

In a further embodiment of the small carrier plate, it can be provided that one of the tufts of bristles that can be placed or placed in the aperture is formed by a sharpened brush filament, in particular a chemically sharpened brush filament, which can be placed The other part of the tuft of hair that has been or has been placed in the hole is made up of a conventional brush. By conventional bristle filament is meant a bristle filament that has substantially the same or the same cross-section over at least a substantial portion of its length or its entire length. The bundle of bristles composed of sharpened brush filaments and the bundle of bristles composed of conventional bristles constitute a mixed bristle field at least after they are secured to the small carrier plate.

The brush filaments may be composed of polyamide and/or polyester. However, the preference is that traditional brush filaments, especially those with the same cross section, are composed of polyamide, while sharpened brush filaments, especially chemically sharpened brush filaments, are composed of polyester, in particular poly(p-phenylene). Made up of butylene formate (abbreviated PBT).

The characteristic of polyesters is that they contain only a small amount or even no moisture at all. In particular, brine may be used on the chemical sharpening of the brush filaments and then removed in a cleaning procedure. In this case, the cleaning brush filaments may have to be dried for subsequent processing. The use of polyester as a material for chemically sharpened brush filaments, and the fact that the polyester contains only a small amount or no moisture at all, contributes to the drying process of the brushed filaments and accelerates the drying. The drying process in this way can be carried out on a scale that is meaningful for a pair of industries.

Advantageously, the bristle bundle is melted after the material bulge, and is melted After the solution material is pressed into the beam fixing surface, it is connected to the small carrier plate by shape fitting and/or force fitting. In this way, a reliable bundle of bristles can be secured in or on the small carrier plate, which can withstand the pull-out force received.

Advantageously, the material projections are designed to be knob-shaped, and the material projections can be laterally projected from the rear side of the small carrier plate. Lateral means that in this connection, the material bulge substantially continues the bundle of bristles placed in the small carrier plate and may protrude from the rear side of the small carrier plate. Advantageously, the longitudinal center axis of one of the material projections is at right angles to the rear side of the small carrier plate.

Furthermore, it can be provided that the material projections are distributed evenly around the holes of the small carrier plate or between the holes. This method facilitates the uniform distribution of the melt, in particular after the melt is pressed into the bundle fixing surface, evenly distributed on the rear side of the small carrier plate and between the end portions of the bristle bundles and especially in the individual bristle filaments of the tufts of bristles And thus contribute to the reliable attachment of the bristle bundles within the small carrier plate.

In order to be able to produce bristle fields having different tufts of bristles, it is advantageous if the holes in the small carrier have different cross sections. Thus, the holes can have, for example, a circular arc and/or an olive shape and/or a circular shape and/or a polygonal cross section. The combination of holes with different cross sections is feasible. In addition, the holes can be designed to grow holes.

The small carrier plate of the invention can be produced in a particularly simple manner, in that the material projection is integrally connected to the small carrier plate and/or when the material projection is composed of the same material as the small carrier plate, in particular a meltable plastic. The composition of the material is preferably a thermoplastic material. The material constituting the material protrusion may have a lower or higher melting ratio than the material constituting the bristles and/or the tuft of bristles point. A typical material constituting a small carrier plate and/or a material protrusion on the rear side of the small carrier plate is a plastic material polypropylene. A typical material constituting the bristle bundle and the bristle filament is polybutylene terephthalate (abbreviated PBT).

Advantageously, the material projection tapers towards its free end, in particular tapered. When the material protrusion has a tapered shape, the material protrusion is significantly more meltable when the melting rod is pressed.

It is particularly advantageous for the small carrier plate to have an infinitely long and closed, in particular right-angle, confinement ring projecting from the rear side of the small carrier plate on its rear side away from the tuft of bristles. This restriction ring can surround the hole and the material projection and includes the rear side of the small carrier plate. The limiting ring on the rear side of the small carrier plate prevents the molten material of the molten material from overflowing laterally under the pressure of the welding rod, and additionally contributes to melting when the molten material is pressed to the bundle fixing surface of the small carrier plate. Reliable guidance of material bumps.

In order to prevent the melt from being extruded laterally, it is particularly reliable that the limiting ring of the small carrier plate has at least one half of the height of the material of the material provided on the rear side of the small carrier plate. In a particularly advantageous embodiment of the small carrier plate, the limiting ring can be raised above the material of the rear side of the small carrier plate, in particular twice as high. Thus, when the molten material is pressed, in particular by a melting rod, to the beam-fixing plane of the small carrier plate, the molten material of the molten material protrusion can be prevented particularly reliably and laterally.

In a further advantageous embodiment of the small carrier plate according to the invention, it can be provided that the small carrier plate is at least behind the bristle bundle, at least in the tuft of bristles After being placed in the hole and/or after the material bulge is melted and pressed, it has a cover, in particular an in-mold method that can be injection molded or injection molded. This cover shields the melted material projections on the back side of the small carrier plate together with the ends of the tufts of bristles. In addition, the cover helps the bristles to be properly secured in their position of use and provides a flat surface on the back side of the small carrier plate, facilitating the attachment of the small carrier plate to a brush, particularly to a toothbrush.

The object of the present invention is achieved by the feature of claim 13 in the brush of the above-mentioned definition, in particular by means of a small carrier plate as a small carrier plate of the invention, that is to say according to patent claims 1 to 12 Any one of them, and reached.

It may be particularly advantageous for the small carrier plate to be clamped in the small carrier plate receiver. Additionally or additionally, the small carrier plate is glued in the small carrier plate holder and/or welded, in particular by an ultrasonic welding method. In this way, the small carrier plate can be securely attached to the brush.

Another method of attaching the small carrier plate to the brush is that the small carrier plate is attached to the brush by an in-mold method, in particular to a small carrier plate holder of the brush.

The small carrier sheets of the present invention allow for processing, particularly in the apparatus for making brushes, particularly toothbrushes, of the above-described methods, using the aforementioned methods. The device has an independent inventive quality and is particularly characterized in that the delivery device is electrically grounded to release electrostatic charges attached to the brush filaments and/or tufts that need to be transported.

By means of at least one removal device, the individual tufts of bristles can be taken out of the bristles of the bristles with the bristles, in order to be able to feed the tufts of bristles to the conveying device, it is advantageous for the conveying device to have at least one accommodating device, the side of the hollow conduit material The end is then placed on it. Advantageously, the at least one bundle of receiving means and/or the hollow conduit can be electrically grounded, the static charge is drawn away by the brush filaments to be transported and by the bundle of bristles, and the brush filaments and/or tufts of bristles to be transported are avoided. Electrostatic charging occurs as it is transported by the transport device.

In order to effectively dissociate the electrostatic charge, it may be advantageous for the at least one of the at least one containment device and/or the at least one of the hollow conduits to have at least one electrically grounded contact or ground contact, the pair of tufts and/or included The brush filaments in the tufts are intermittently contacted at least in time when transported via the beam holding device and/or via at least one hollow conduit.

Preferably, or copper, which is in contact with the bristle bundle and/or the bristle filaments contained therein.

It is advantageous for the hollow conduit of the device to be formed as a tube from an elastic material and/or as a Bowden sleeve and/or as a tube connection from a conductive material, in particular from metal, to steel, not Stainless steel or copper is preferred. However, it is preferred to use a hollow conduit constructed of a Bowden sleeve, which is particularly cost effective and well suited to conduct off electrostatic charges.

A particularly efficient tuft of bristles is fed to a bundle of holding plates on the apparatus in that the conveyor has a number of hollow conduits corresponding to the number of apertures in the bundle retaining plate.

Advantageously, especially in view of the implementation of the aforementioned method, it is advantageous for the bundle retaining plate to be designed as a transport plate that can be transferred to a subsequent processing device, in particular to a welding station. In a further embodiment of the invention, the bundle retaining plate can additionally have at least one small carrier plate holder for the use of a small carrier plate on the side of the transport device remote from the receiving position, the small carrier plate being particularly patented Request any one of items 1 to 12.

It has to be pointed out that the bundle retaining plate can also be a brush partial body or an injection-type insert which can be processed at subsequent stations of the device after loading the bundle of bristles.

In a further embodiment of the device, it is particularly important to provide that the hollow conduits of the delivery device each lead to a guiding channel of a guiding element. This guiding element can also be referred to as a feed block. The guiding channels of the guiding elements or the feed blocks are each designed as a through opening. It should be noted that the distance from the leading side of the guiding channel to each other may be smaller than the distance from the introduction side. It is particularly advantageous if the outlet of the feed channel corresponds to the combination of the holes of the bundle holding plate on which the tufts of bristles are to be inserted and/or is arranged to open into these holes. In this way, the insertion of the bundle holding plate after the bristle bundle has been fed by the conveying device can be carried out particularly efficiently.

The feed channels of the guiding elements or the guiding blocks act as the same funnel, and the bundles of bristles to be fed are fed into the holding plate in close proximity to each other during their transport.

In order to be able to place the tufts of bristles into the holes of the small carrier plate held on the device at the required compression density, it is advantageous for the device to have a bundle between the bundle retaining plate and a small carrier plate to which the bristles are to be inserted. A funnel plate, preferably as described in any one of claims 1 to 12, having a funnel passage that tapers in particular toward the direction of transport of the tufts of bristles. The tufts of bristles are arranged in a bundle holding plate and directed toward a small carrier plate to be inserted, through which the tufts of bristles can be introduced by the bundle holding plates and held on the funnel plate to be held on the small carrier plates of the funnel plates. It is better in the middle of the hole in the carrier plate. Advantageously, the inlet of the funnel passage corresponds in number and in combination to the outlet of the bore of the bundle retaining plate, and the outlet of the funnel passage corresponds in number and in combination to the bore of the small carrier plate. Furthermore, it is advantageous if the outlet opening of the funnel channel is held in the hole of one of the small carrier plates on the funnel plate so that the bundle of bristles is introduced as easily as possible from the bundle holding plate via the funnel plate into the small carrier plate to be inserted.

In order for the bristle bundle fed by the conveyor of the bundle holding plate to reliably enter the aperture of a small carrier plate held on the funnel plate via the funnel plate at a desired compression density, the device may have a compression station, The station has at least one compression rod having a number and combination of the same as the hole of the bundle holding plate and/or coincident with the funnel channel of the funnel plate and/or coincident with the hole of the small carrier plate Compressed finger. By means of the compression finger, in particular the tufts of bristles placed in the funnel plate and/or the bundle holding plate can be placed in the device, in particular on the funnel plate and/or the holding plate, small In the hole of the carrier plate.

In this way, the bristle filaments that are assembled into a tuft of bristles can be fed in a low compression density necessary for transporting the conveying device by a gas or air stream, and then mechanically placed by means of a compression rod to be held small. The holes in the carrier plate are simultaneously compressed to the desired higher compression density. In particular, at higher compression densities, the mechanical compression of the tufts of bristles can also contribute to the aforementioned funnel passage of the funnel plate, representing a particularly simple way of compressing and arranging the bristle bundles into a small load-bearing plate. .

In particular, it may be advantageous to carry out the foregoing method, the apparatus having a transport jaw and a welding station. The transport jaws may be preferably designed as a turntable having at least one transport receptacle for use with a funnel panel and/or a bundle retaining plate loaded with tufts of bristles and/or having at least one small carrier plate. It must be pointed out that the bundle retaining plate, which can additionally assume the function of the conveying plate, can be transported to the welding station by means of the conveying jaws after loading the bundle of bristles and/or loading at least one small carrier plate, and the bundle of bristles is The welding station can be connected to at least one small carrier plate, in particular in a form-fitting and/or force-fitting manner.

In one embodiment of the invention, the at least one weld bar can be heated to a temperature of about 500 ° C to weld the bundle of bristles to each of the small carrier plates.

It is to be noted here that the use of a small carrier plate of the invention according to any one of claims 1 to 12, together with the device described above, greatly simplifies the manufacture of the tufts of bristles, in particular if the foregoing description is also used The method.

If the brush filaments used are chemically sharpened brush filaments, so-called chemically tapered filaments CTF's, the advantages of the device for making tufts of bristles can be particularly large, since these particularly delicate brush filaments are When the gas stream or the air stream is transported via the transport device, electrostatic charging may be significantly encountered, so that the feeding of such chemically sharpened brush filaments can only be accomplished with disproportionately large expenditures.

Advantageously, the device has a de-stacking station that is placed in front of the material cassette for removing the brush filaments by a bundle of bundles in the wire disc. The de-stacking station can have at least one cutting device having at least one cutting tool for cutting the bundle of the wire disc and having at least one gripping mechanism for removing the opened bundle.

It is easier to suck at least one of the suction claws of the transfer station and then carry out the processing of at least one wire tray in such a manner that the bundle of the wire tray is held in one set. The sleeve is radially tightened in the longitudinal direction of the use position to gather the brush filaments in the wire disc so that the upper side of the front end of the disc has no sleeve.

Advantageously, the sleeve is designed as an infinitely long strip, that is to say as a coil, designed as an overlapping section of the brushed bundle of filaments, or as an overlapping sleeve. Advantageously, the height of the bundle corresponds to the length of the filament of the wire disc.

The material suitable for the sheath is both elastic and airtight, such as polyethylene, preferably PE-LD.

Furthermore, the device can have one and a, for example the aforementioned feed station, which is connected to the transfer station, which comprises at least one, in particular a conveyor belt, which is designed as a conveyor belt. The wire disc can be fed to the transfer station and/or to at least one of the suction jaws on at least one of the load-bearing surfaces. In order to be able to reliably pick individual individual discs from the bearing surface, for example by means of suction jaws, it is advantageous for the spindle to maintain a distance on at least one bearing surface which is preferably a conveyor belt designed as a conveyor belt. In order to maintain the distance of the wire disc on the bearing surface, the bearing surface can have receiving recesses which are preferably arranged in a plurality of distances, in particular in the conveying direction, in which individual wire discs are placed, and in which the wire disc can be continuously transported. .

If the feed station is at least one of its longitudinal sides, in particular one of the longitudinal sides of at least one of the load-bearing surfaces, having at least one fixed storage surface adjacent to the at least one load-bearing surface for individually prepared wire spools And/or for at least part In the case of a delivery container for the partial loading of the wire disc, the bearing surfaces, in particular the receiving recesses of the bearing surface which are designed to be spaced apart from each other on the bearing surface, can be used to load the wire disc very quickly and efficiently when required. To this end, the wire disc can be placed on the carrying surface or taken out from the adjacent storage surface or directly removed from the ready delivery container, which can also be held on the adjacent storage surface as long as it is on the carrying surface There is again space for feeding to the transfer station and/or to the wire tray of the at least one gripper fed to the transfer station.

It has to be pointed out that the storage surface is in particular designed in the form of a flat plate and/or a long plate and can advantageously extend over at least a portion of the length of the bearing surface, but is fixed relative to the bearing surface.

It will be apparent that the apparatus of the present invention can have more than one bundle retaining plate and/or funnel plate.

It is better to use thermoplastic plastic. The material constituting the bristle filaments 2, 2a and/or the bristle bundles 5, 5a may have a lower melting point than the melting point of the material from which the material projection 54 is made. However, an embodiment is preferred in which the material constituting the material projection 54 has a lower melting point which is lower than the melting point of the material constituting the bristle filaments 2, 2a and/or the bristle bundles 5, 5a.

3 to 5 and FIG. 6 to FIG. 9 additionally show that the small carrier plate 17 has an infinitely long and closed restriction ring which is protruded from the rear side 53 of the small carrier plate 17 at its rear side 53 away from the bristle bundles 5, 5a. 55, which surrounds the aperture 24 and the material projection 54 and comprises a rear side 53 of the small carrier plate 17. The limiting ring 55 of the small carrier plate 17 is at least one height equal to one half of the height of the material projection 54 provided on the rear side 53 of the small carrier plate 17.

In the embodiment in which one of the small carrier plates 17 is not shown, the restriction ring 55 is higher than the material projections 54 on the rear side 53 of the small carrier plate 17.

In the embodiment of the small carrier plate 17 shown in Figures 6 to 9, it is provided on its rear side 53 away from the bundle of bristles 5, 5a, at least after the bristles 5 are placed in the holes 24 and/or in the material bulge After melting and being pressed, it has a cover 59. This cover 59 has been shown in Figure 9 and can be injection molded, for example, in an in-mold process.

Then, the material protrusion 54 protruding backward from the rear side 53 of the small carrier plate 17 away from the bristle bundle 5 is heated and melted in the welding station 15 to connect the bristle bundles 5, 5a and the small carrier plates 17, and the material convex after melting One of the melts 54 is pressed into the fixed faces of the bristle bundles 5, 5a, so that the melt flows between the ends of the bristle bundles protruding from the rear side 53 of each of the small carrier plates 17 and between the bristle filaments of the bristle bundles 5, 5a And then solidify.

The material projection 54 on the small carrier plate 17 is heated by the welding rod 32, melted and pressed into one of the fixing faces of the bristle bundles 5, 5a, and the bristle bundles 5, 5a are fixed to the small carrier plate 17.

The bristle bundles fed to the bundle holding plate 9 as needed may be the tufts 5 of the conventional bristle 2 and/or the bristle 2a from the chemically sharpened - so-called CTF's or chemically tapered filaments - 5a.

The brush wires 2, 2a are bundled by a flexible and airtight sheath 35 It is fed to the transfer station 42 in the wire tray 36. The wire spool 36 fed to the transfer station 42 is then sucked by a suction jaw 43 disposed to the transfer station 42, the suction jaw 43 contacting the free upper or front end side 46 of the wire spool 36 with its suction plate 45 and sucking it.

In particular, the elastic and airtight sheath 35, previously referred to as the sleeve, is oriented transversely to the longitudinal axis of the brush 2, 2a and inwardly to the longitudinal axis at right angles to the upper side 46 of each disk 36. Suction is applied, and via this, the bristle filaments 2, 2a of the sucked wire disc 36 are stabilized.

After the suction claw 43 sucks a wire tray 36, the wire tray 36 is transferred to the removal station 34 by the suction claws 43.

The wire tray 36 fed to the transfer station 42 in the drawing, at least when it is composed of the chemically sharpened brush 2a, is subjected to a spinning finish containing antistatic additives for CFT's as previously described. The electrostatic charging of the brush filaments 2, 2a when transported by the transport device 6 is reduced.

According to Figure 1, the gripper 43 is provided on a retainer 56 which in turn is slidable in a rail system 57. The suction claws 43 can be slid in the horizontal direction as well as in the vertical direction by means of the holder 56, and the individual wire trays 36 are transferred from the transfer station 42 to the removal station 34.

At the removal station 34, the bundle 35 of the wire reel 36 is opened and removed, and the bristle filaments 2, 2a released by the sheath 35 are automatically fed to the material crucible 3.

The device 1 has a feed station 47 before the transfer station 42. In this embodiment, the wire tray 36 is fed to the transfer station by means of a feed station on a bearing surface of a total of three feed stations 47 designed as conveyor belts 48. 42 and the suction claw 43 of the transfer station.

The wire tray 36 is held at the feed station 47 on three load-bearing surfaces designed as a conveyor belt 48, or as shown in Figure 1, in the delivery container 52, and is preferably manually, if desired, directly The delivery container 52 comes out and is moved to three carrying surfaces designed as conveyor belts 48, in particular in the direction of transport of the three conveyor belts 48.

The present method and apparatus 1 for making a brush bristle field, a small carrier plate 17 and a brush 60 loaded with such a small carrier plate 17 allow for a simplified brushing of the brushing field, among other things, by a gas The bristle bundles 5, 5a, which are conveyed by the conveying device 6 to the bundle holding plate 9 via the conveying device 6, are electrostatically discharged when they are conveyed by the conveying device 6, so that they can be conveyed more easily via the conveying device 6, and in that the bristle bundle 5 is lowered, 5a is fixed in the small carrier plate 17 in a non-fixative manner, since the small carrier plate 17 has a material protrusion 54 on the rear side which is melted and then pressed into a bundle of fixing faces, which will be placed into a small carrier. The bristle bundles 5, 5a in the holes 24 of the plate 17 are joined to the small carrier plate 17 in a simple manner in a form-fitting and/or force-fitting manner.
