The invention relates to a method for producing bristle fields for brushes or bristle bundles for brushes, wherein bristle tufts are filled into holes of molds, wherein first the bristle tufts are formed from single bristles by a bristle supply is separated into bristle tufts, after which the bristles tufts of the mold with Help supplied an air flow and introduced into the perforations of the mold.

The invention further relates to a device for producing bristle fields for brushes or bristle bundles for brushes, in which the ends of individual plastic bristles of a bristle tuft are fused together and / or with those of a neighboring tuft, with a perforated shape, in which holes each a bristle tuft fits, with supply lines are provided to the mold and leads to each hole to be filled a conduit to which lines means for generating an air flow to the mold can be connected.

From DE-PS 845933 it is already known to deduct the bristles of bristle tufts continuously as strands of a supply and to introduce in continuous perforations of a half-mold. At their side facing away from the later-to-be-merged attachment end, these strands are each cut off to form bristles of a predetermined length, the later working ends of the bristles being formed at the interface. This means that these working ends are sharp-edged and lead to a danger or injury to the gums, for example, when used in toothbrushes. When used as a hairbrush, the scalp is correspondingly at risk. This applies even more to who · the working ends of the plastic bristles should also be placed within a tuft in a special geometric shape, so the individual tufts, for example, conical, hemispherical or beveled, for example, when brushing better in the interstices to be able to penetrate between individual teeth.

It has therefore undergone trimmed bristles subsequent processing, by which the later working end of each bristle is to be rounded more or less. However, this is only possible if and only within limits, if an overall flat bristle field is present or maintained.

From DE-OS 2335Ί68 it is known to remove the bristles in each case in tufts from a bristle stock using a Entnahmplattc with clamping holes and convert into tubular individual forms, the arrangement of the arrangement of the sampling tube must correspond exactly. There is the significant problem that the edges of the sampling tube on the one hand and the edges of the individual forms on the other hand can lead to compressions of slightly laterally projecting bristles, so that in a short time the exact parallel position of the bristles in the bristle magazine or supply is no longer given and the tufts not can be more complete. In addition, a lot of time and a difficult and mechanically sophisticated device is required to perform this type of feeding a mold with bristles, so that the device according to this document can not fulfill the purpose in a rational and inexpensive form and above all as fast as possible bristles to summarize bristle fields.

From DE-OS 3405001 a method of the type mentioned above has become known with a corresponding device, wherein the mentioned air flow is generated by compressed air. This means that the bristles before being transported in the form not only tuft-wise divided, but also already must be fused together as a Befc promotion of tufted, but still individual bristles by lines with the aid of compressed air inevitably to iiiner mutual turbulence of the individual bristles and to different fast promotions of these bristles fü.iren and outside the particular on curvatures of the lines there is a risk that bristles get stuck and then form a jam. In a complex manner, therefore, bristle tufts must first be separated and fused, before they can then be brought with compressed air into a mold, where their fused ends must be overmoulded again.

This also makes it possible to achieve no rational and above all fast production of brush fields and brushes or brushes. There is therefore the object to provide a method and also a device of the type mentioned above, which can be formed in a simple and efficient way from Einzelboisten bristle tufts bristle fields, where the bristle tufts and the entire bristle field arbitrary geometric arrangements of the free working ends of the individual Bristles may have and in which the ends of the individual bristle tufts may thus be spherical, conical, pointed, bevelled, etc., but in spite of such geometric shapes of the tufts, the individual bristles may be rounded. At the same time a rational and fast brush or brush production should be possible.

To solve this problem, the method of the type mentioned above is characterized in that the air flow for conveying the bristle tufts is generated with negative pressure and that the later free working ends facing away from the bristles are subsequently fused to the introduction into the perforations of the mold.

Thus, the later working ends can be rounded before being introduced into the mold. Instead of the recent removal of bristles and their merger into individual tufts, which then have to be encapsulated in another form, so the tuft of not yet fused bristles can be transported much faster with the help of the negative pressure in a form where the fusion and connection takes place , so that a higher Produktiansgeschwindigkeit is possible. In addition, there is a cheaper and faster transport of the bristles into the mold. Even relatively long conveyor lines can be overcome in this way. Since the flow is caused by negative pressure and not as in other air or gas transportations by pressure, more favorable flow conditions are possible in which mutual turbulence of the individual bristles or even congestion can be avoided.

The bristles can be introduced into the mold in approximately vertical orientation. This has the advantage that the insertion of the bristles into the mold can be assisted by gravity.

It is particularly useful if the bristle tufts are sucked through a placed on the form, with matching holes wia the mold equipped holding plate, after which the fusible ends of the bristles over the plate survive or at least in one after the top of the plate towards expanding Punching range project, and then when these bristles are fused together and / or with the plate or with this in the same direction as the protruding ends of the bristles protruding projections and optionally with the ends of the neighboring bristle tufts.

By such a holding and adapter plate, the tuft-like sucking of the bristles in the form can be improved insofar as especially contrary to the suction expanding perforations of this plate lead the individual tufts targeted in the perforations of the half-mold and can occur. At the same time, the ends of the bristle tufts to be joined are held together well and the heat of fusion to be applied at these ends is kept away from the bristle areas by the plate which are not to be fused together. In addition, this plate allows a better Verbindu ng with a later brush body or may even be directly even the brush body. If, for example, the holding plate is subsequently encapsulated, it is again possible to prevent melt of the spray material from getting between the individual bristles, thereby bonding and connecting the bristle tufts to an excessively long length. In this way, each individual bristle of a bristle tuft remains free of the afterbias,

so that the elasticity of the single bristle remains intact despite the fusing and bonding over or in the holding plate below the same.

If protrusions protruding from the holding plate are likewise fused with the bristle ends projecting there first, a very stable connection of all bristles within such a bristle field with holding plate results.

A further improvement and refinement of the method according to the invention for mutual fixing of the individual bristles with one another and also with the holding plate can be achieved by utilizing the conveyance of the bristles by means of underpressure ii the shape in that, after the ends of the bristles have melted, they are still soft or doughy Melt under pressure, in particular set negative pressure and thereby at least partially pressed within the holding plate spaces between the bristles and / or between them and the holding plate is pressed or sucked. The melt can thus further stabilize the bristle areas located inside the holding plate and, above all, seal off the interstices otherwise located between bristles in such a way that no bacteria and no toothpaste sludge can penetrate. In an advantageous manner, the negative pressure which also serves for conveying into the mold can be utilized. After fusing the bristles, the holding plate can be connected to a brush body, in particular welded, high-frequency welded, glued, permanently locked or screwed. As a result, even such bristle tufts, which are only balled by their fusion, but otherwise still be displaced relative to the holding plate, are secured against axial displacement during pressurization. After the connection to the holding plate, the bristle field can then be ejected from the mold together with the holding plate or with the brush body.

By filling the bristles by means of negative pressure in the mold, there are a variety of benefits not only in the transport, which in contrast to a compressed air transport practically trouble-free and still very effective and fast can be done and the promotion of not yet connected, but only tuft-like isolated bristles allowed, but it can easily be combined bristles of different properties in one and the same bristle field. For example, softer bristles with harder bristles may be grouped together in any bristle pattern by having a portion of the suction lines lead to a supply of bristle tufts with softer bristles, while harder bristles from another supply provide additional suction lines to the same shape but other perforations therein can be. Also differently colored bristle tufts are possible within a bristle field, so that the brush manufacturer hai the possibility to influence the aesthetic effect of the brush by differently colored bristle tufts. He can even achieve, for example, by using only a single bristle tuft with respect to the other bristle tufts of other color a mark of origin of his brush.

Nevertheless, the speed of operation and in particular the speed of filling the mold is not affected and, since no mechanical transport means, but a generated by vacuum gas flow is used to transfer the bristle tufts in the form is also a problem-free overflow without congestion, compression and without Crossing of individual bristles, for example, on line bends or Mündunnseintritt in the recess of the mold possible, especially when the negative pressure is applied to the mold, so that the negative pressure automatically directs the bristles in the mold, thereby thereby and by the ability to simultaneously all Fill bristles of a bristle field via corresponding parallel vacuum lines in the mold, very high speeds are possible. The inventive device of the type mentioned is to solve the problem is characterized in that the mouths of the lines and the mold are movable relative to each other and that the form has a terminal for applying a negative pressure to the individual perforations.

Since the negative pressure is applied to the perforations of the mold, so formed when connecting the mouths of the lines with the entrances of the holes or a holding plate thereon a continuous, under suction pressure airway into the holes in, so that the bristles of the individual lines be safely transferred to the mold. In this case, it does not matter in an advantageous manner if, during transport of the bristle tufts, individual bristles of such a tuft are conveyed faster than the others, because they are all targeted into a perforation and then receive the predetermined desired tuft shape through the perforation form. Since the mouths of the lines and the mold are movable relative to each other, in particular the mouths can also be moved away from the mold, on the one hand different bristle fields form and on the other hand the required access for a melting device for subsequent fusion of the bristles with each other and / or with a holding plate create. In this case, both the line mouths and the molds can be movable, so that the molds can be transported, for example, in a manner to be described after their filling to a melting station, while already a new form can be brought into the region of the mouths of the lines.

The guide lines may be at their insertion end-at which the bristles are sucked into the lines-the distance from each other, or be adjustable to the distance to each other, in which the tufts are provided before their insertion into the mold, and the outlets or mouths of the lines may be provided or adjustable in the position of use in the distance and the arrangement corresponding to the hole arrangement of the mold and / or a holding plate. Since each bristle tufts after its formation of a bristle supply has its own supply line to the corresponding perforation of the mold, can be in this way any geometric arrangements of bristle tufts form each other and feed any shape by the lines can be adjusted to each. An expedient embodiment of the device consists in the fact that at least one bristle magazine can be provided, in which the individual bristles are pressed against a sliding and / or rotary removal slide, and that the removal slide movable transversely to the removal arranged at a distance from each other, the bristle supply facing, open recesses for forming bristle tufts and with its recesses having this region from the bristle magazine to below the individual openings of the lines is displaced or rotated. It can thus in a very simple manner with the help of such a removal slide, in which the bristle facing edge edge-open recesses or recesses are provided according to the shape and size of the bristle tufts later, the respective bristle tufts are formed and transferred to the inlet region of the suction lines, said after Exit from the bristle magazine corresponding counterholder the open-edged recesses with the individual bristle tufts

shut down. The individual openings of the suction lines can be oriented in a simple manner to those points or be in which the bristle tufts are located after removal by means of the slider. Simple and fast back and forth movements of this slider are therefore sufficient to form the desired bristle tufts from a supply of individual bristles and position them so that they can be sucked into the mold in the manner already mentioned. As lines hoses and / or pipes may be provided and in particular in the region of the insertion end and / or the mouth can be flexible to adjust these areas, the lines. This facilitates the already mentioned adjustment and mobility especially in the mouth areas.

Embodiments of the supply lines and in particular their inlet openings and also the outlets are the subject matter of claims 11 and 12. The measures specified therein facilitate on the one hand the safe sucking of all bristles of a bristle tufts and on the other hand the assignment to a holding plate and their perforation pattern.

In order to further improve the introduction of the individual bristles into the perforation of the mold and in particular to achieve a dense filling with as many bristles as possible in such a perforation ο that the "last" incoming bristles compresses already located in the perforations bristles, it is expedient If the speed of introduction of the bristles is increased by the fact that the mouths of the lines have tapers or constrictions, preferably in the manner of a venturi nozzle, with subsequent widening increased to the degree of constriction, so that the bristles get into the hole of the mold with a correspondingly high speed and a correspondingly high momentum and can push between already in the l.ochung located bristles because of their previously already balled ends other bristle not me hr passes into the perforation, it may still be advantageous in the subsequent fusion process, because it can then be mitverschmolzen with the protruding and merging ends of the filled bristles.

Another embodiment of the device of very considerable importance may be that the holes for receiving the bristle tufts are in the form of blind holes whose bottom or inner end faces have a negative shape or contour for forming the ends of the respective bristle tufts and, for example, as a hollow cone or tip, hollow hemisphere, chamfer, plane or a combination of these molds are formed. Thus, when sucking a bristle tuft equal to the geometric shape of its subsequent working end are made so that trimming the working ends of the bristle tufts after the summary bristle fields is no longer required and thus the working ends of the individual bristles can be rounded from the outset.

Of all holes or perforations of the mold can each have a suction duct laterally above the bottom thereof, optionally right angles and these channels can lead to the suction connection and be summarized. As a result, the suction pressure is maintained up to the inside of the perforations of the mold, but without individual bristles can be drawn into the suction channels, as would be possible with a connection in extension of the perforations of the mold.

An alternative solution with respect to the suction connections may consist in that the bottoms of the perforations in the mold are provided in a porous insert, in particular in a ceramic insert, sintered insert, sieve, felt, textiles or the like, under which one connected to the vacuum connection or provided chamber od. Like. Is provided. In this case, the negative pressure can be applied directly in extension of the individual perforations, since the pores of such a porous insert are much smaller than the cross section of a single bristle.

In order to increase the security that each bristle tufts after filling in the mold has the desired geomtrical training and above all all individual bristles in the correct position in their longitudinal direction, the bottoms of the individual perforations of the front side of slidable in the punch punches be formed, which are arranged during filling deeper than when fusing the bristles and in a the exact tuft length corresponding height, possibly via the suction channels of the perforations, can be raised. Thus, the suction channels can be relatively low, so that the bristles are sucked correspondingly deep into the holes. However, if due to a certain distance of the suction channels of the Lochungsboden the one or the other bristle does not initially reach this floor, this is nevertheless accomplished by the subsequent lifting of the floors.

A further embodiment of the invention of its own worthy of protection may consist in a device of the type mentioned in that the bottoms of the perforations or holes of the form are corrugated or profiled or roughened, with individual bristles each between the thereby formed elevations and others on these elevations fit, so that the individual bristles of a bristle tufts have slightly different lengths at the free end of working. It has been found that a much better cleaning result can be achieved with such toothbrushes, in which not only the working end of the entire bristle tufts has a favorable geometric shape, but also in which the individual bristles of a bristle tufts not all exactly on the surface of this geometric shape lie, but each have slightly different lengths, so that therefore individual bristles slightly overcoming neighboring bristles.

when the said corrugation or profiling or roughening is provided at the bottoms of the perforations of the mold, the desired arrangement of the free ends of the bristles being particularly easily and quickly achieved when sucked into the mold and in particular subsequently the soil is still in a final state Altitude is shifted.

Further embodiments of the device according to the invention are subject matter of claims 18 to 25.

In this case, claim 18 specifies a configuration with which simultaneously several shapes can be charged in the same advantageous manner with bristles, so that an even more efficient and faster brush production is possible.

This is also the measure of claim 19, but also includes a way, as in the same bristle field different bristles and / or bristle tufts can be arranged.

Claim 20 represents a simple and expedient embodiment, as with a single slider already a much larger number of bristle tufts and possibly also can be provided by different bristles, as in each of the bristle magazines mentioned therein different bristles can be kept.

Claim 21 is concerned with the possibility of further accelerating and rationalizing the manufacture, thereby increasing the possibility of combining different bristles and shapes of tufts of bristles.

Claim 23 is an embodiment of the entire apparatus in such a way that also the individual working steps, such as the filling of the mold, the subsequent fusing and the connection to a brush body, can each be carried out approximately simultaneously.

An essential embodiment of the device includes claim 25, wherein the holding and insertion plate mentioned therein, which has already been mentioned above, initially part of the device, but later forms part of the brush produced. Before each filling of a mold so nsus such plate is to supply, for which purpose a workstation for placing such holding plates on the molds may be provided on the chain belt according to claim 24 before the station for filling the molds

In addition, the improvement of the retraction of the bristles and better holding the bristle tufts especially after fusing and possibly when overmolding the fused bristle ends, this plate has the additional advantage that they provide the brush manufacturer further design options z. B. offers the effect that this plate and the actual brush body can be colored differently. Are the holes of the plate slightly conical, resulting in so-called open bristle bundles, in which the individual bristles are not compressed by an anchor and therefore stand separately from each other and thus can achieve better cleaning results.

A significant advantage of filling the mold with the help of negative pressure is that possibly at the bristle ends by their rounding still stuck-on grinding dust is virtually completely removed, while previously in the conventional punching this grinding dust could hardly be removed and each new toothbrush a considerable amount of such Abrasive dust adheres.

Since the bristles are sucked in and fixed by fusing to the holding plate, the conventional anchor attachment eliminates the notches caused by the Ankerbefostigung that could previously lead to stress cracks in the bristle field. Thus, it is also avoided that individual bristles emigrate into such anchor furrows and then protrude individually.

In this case, all these advantages are achieved especially when combining one or more of the features described above and included in the claims and measures at a very efficient and fast production, in which all bristles of a bristle field can be filled simultaneously in the mold.

In cases where, in each case, the bristles of individual bristle tufts fused, but the bristle tufts are not connected to each other at the same time, these bristle tufts fused to bristle tufts can be advantageously used to make brushes, advantageously producing the individual bristle bundles with high bristle tufts Working speed and precision and at the same time good strength of the bristle bundles can be done.

If bristle fields are to be formed from continuous bristle tufts with a retaining plate connecting and stabilizing them, however, it is favorable if the perforations in the retaining plate on the upper side facing away from the working ends of the bristles have depressions which absorb the fused ends of the bristles of the individual bristle tufts and which optionally merge into one another at the mutually facing edges below the plate surface.

Further, on the side of the holding and insertion plate, on which the bristles to be fused protrude between the perforations, protrusions, protrusions, knobs or the like, of fusible material. With these, the protruding bristles can then be fused, if a corresponding fusible plug is pressed down sufficiently far until it touches these projections, nubs or the like and the bristle ends, melts and simultaneously upsets. The melt, which is formed by the bristle ends and these projections of the plate can then flow into one another and to a certain extent cause welding, especially when the bristles and the plate consist of the same material. But even with different materials, this results in an intimate connection between the bristles and the plate.

The holding plate may have a flange or a sealing lip, which engages over the edge after insertion into a receiving the receiving plate in the recess of the brush body. This prevents, for example, detergent gradually penetrate into the holding plate in receiving recess and deteriorate the appearance of the brush and also gradually loosen the connection. In the claims 29 and 30, a likewise suitable for solving the problem device of the type mentioned above, which allows a leadless supply of the bristles to the forms and their perforations, but again in an advantageous manner negative pressure for introducing the bristles in the perforations of Forms is used. Such a device is advantageous when a separating slide for the bristle tufts can be moved directly above the inlet openings of the mold or the holding plate lying thereon.

The claims 32 and 33 relate to the rotary sampling slide, which allows a significant acceleration of the workflow vind the bristle supply because it can be continuously moved in the same direction and rotated, so the time for a free stroke, the case of a sliding withdrawal slide for the return movement the or the bristle magazines is saved.

A device indicated as a whole by 1, especially in FIGS. 1, 14, 14 and 15, is used for producing bristle fields 2 (cf., for example, FIGS. 8, 9 and 10) or brushes 3 (cf., in turn, FIG and 10). The ends of individual plastic bristles 4 of a bristle tufts 5 according to FIG. 5 or FIG. 6 are fused together and / or with those of a neighboring tuft. To the device 1 according to FIGS. 1 and 4 belongs a perforated 6 form 7, which is a half-mold, i. whose holes are 6 blind holes. In each of these holes 6 a bristle tufts 5 fits, but the ends to be fused 8 of the bristles 4 according to FIG. 1 survive.

According to Fig. 1.4 u. 14, the mold 7 gohörende to the device 7 has a connection or connecting piece 9 for applying a negative pressure to the individual perforations 6 and there are supply lines 10, hereinafter also referred to simply as lines 10, provided with each to be filled hole 6 a line 10th leads. The cross sections of these lines 10 correspond to at least those of them to be transported and leading to bristle tufts 5, so that each line 10 can trahsportieren each a tufts 5. The mouths 11 of the lines 10 and the mold 7 are movable relative to each other, as indicated in Fig. 1 and 14 by the double arrow PF 1 for the mouths 11 and in Figure 4 by the arrow Pf 2 for the mold 7.

At their insertion end 12, the guide lines 10 have the distance from each other or are optionally adjustable to such a distance, in which the bristle tufts 5 are provided before their introduction into the mold 7 according to FIGS. 1 and 2. In Fig. 1 it is shown that while the insertion ends 12 are formed or held together by an insertion plate 13. The outlets or orifices 11 of the lines 10 are provided or einsteilbar according to FIG. 1 in the position of use in the distance and the arrangement corresponding to the example in Fig. 3 recognizable hole arrangement of the mold 7 or according to Fig. 1 auflegbaren to the holding plate 14 , Thus, the bristles can be sucked by applying a negative pressure to the terminal 9 at the entrances 12, transported through the lines 10 and drawn into the perforations 6 of the mold 7, in which case of course the Mündungon 11 of the line 10 to the mold 7 and Retaining plate 14 are lowered or the mold 7 is raised.

According to FIGS. 1, 2, 4, 14 and 15, at least one bristle magazine 15 also belongs to the device, wherein in the exemplary embodiment two such bristle magazines 15 are provided with removal points 16 facing each other, which are under pressure from respective opposite sides according to the arrows Pf 3, so that the bristles 4 located in them are brought again and again to the sampling points 16 out and printed. As a result, the bristles 4 are pressed against a removal slide 17 which limits the bristle supply at these removal points 16. This transversely to the removal point 16 movable removal slide 17 has shown in FIG. 2 with spaced apart, the bristle supply respectively facing and this edge-open recesses or recesses 18 for forming the bristle tufts 5. This removal slide 17 is with this these recesses 18 having area the bristle magazine 15 to below the insertion openings 12 of the lines 10 slidably, the drawings show this displacement position.

As lines 10 hoses and / or tubes may be provided, in particular in the region of the insertion end 12 and / or the mouth 11 for carrying out the adjustment movement of these areas, the lines 10 are flexible. The introducers 12 of the lines 10 are connected to an insertion head, in the embodiment of the aforementioned insertion plate 13, or attached to such an insertion head. In this case, the insertion openings 19 are funnel-shaped in the exemplary embodiment with a tapered course of a larger cross-section on the line cross-section, so that all individual bristles 4 of a respective bristle tufts 5 can be sucked in with correspondingly high security and transported on in tufts.

In the exemplary embodiment, the outlets or mouths 11 of the lines 10 are further connected to each other and thereby fixed to an orifice plate 20. If the assignment of the individual orifices 11 to change a bristle image to be changed, the orifice plate 20 may be replaced.

In Figs. 1,4,5,6,14 u. 15 clearly shows that the perforations β for receiving the bristle tufts 5 in the form 7 are blind holes whose bottoms 21 or inner end faces have a negative shape or contour for shaping the free ends of the respective tufts 5 and, for example, as a hollow cone or tip, Hollow hemisphere (FIG. 6), chamfer, plane (middle bristle tufts of FIG. 5) or a combination of these hollow shapes can be formed. When sucking the bristle tufts 5 so the free working ends of these bristle tufts are brought into a desired shape at the same time, without the need for subsequent trimming or shaping of these working ends of the bristle tufts 5, so that the individual bristles can be rounded before.

Of all holes or perforations 6 of the mold 7 each may above the floor 21 suction channels laterally, possibly right-angled depart and these channels can lead to the suction port 9 or be summarized. In the embodiment of FIG. 1.14 u. 15, however, another solution is shown, in which the bottoms 21 of Lochungan 6 in the mold 7 in a porous insert 22, z. B, a sintered or ceramic insert, are provided, under which a provided with the vacuum port 9 chamber 23 is provided. In this way, the suction flow can be directed to the innermost ends of the perforations 6 in the longitudinal direction of the bristles 4 to be inserted and sucked. In Figs. 10 to 12 it is shown that expediently the individual bristles 4 of a bristle tufts 5 z. B. may have two different lengths to achieve a better cleaning effect. This can be achieved in a manner not further illustrated in the drawings by corrugating or profiling or roughening the bottoms 21 of the perforations 6 of the mold 7, with individual bristles 4 each fitting between the raised portions and others corresponding to these raised portions Single bristles 4 of a bristle tufts 5 at the free end of the work obtained especially in Fig. 12 clearly distinguishable slightly different lengths.

Also not closer is shown in the drawing, that the bottoms 21 of the individual perforations 6 may be formed by the front side of each of the perforations 6 displaceable punches, which are arranged during filling deeper than the fusion of the bristles 4 and in one of the exact tuft length corresponding height, possibly via the outgoing of the perforations 6 suction channels, can be raised. Thereby, the desired final length of the individual bristles and bristle tufts is achieved with great certainty, even if e.g. when sucking a bristle tufts one or the other bristle within the perforation 6 with respect to the other remains slightly, which is especially not completely ruled out when the suction channels go off to the side of the holes.

It should be noted that more tufts 10 may be provided for bristle tufts 5 on the device 1, as a single form 7 perforations 6, so that at the same time a plurality of bristle-field forming molds 7 can be fed, whereby the production speed in the production of bristle fields and / or brushes 3 can be significantly increased.

In Fig. 2 it is indicated that the slide 17 for separating the bristle tufts 5 when removing the bristles 4 from the bristle magazine 15 different recesses or recesses 18 to form different bristle tufts 5 and in particular to form bristle tufts 5 different thickness and / or cross-sectional shape , In Fig. 3 it can be seen that bristle fields and bristle images are conceivable in which on the one hand round, on the other hand square and also elongated cross-sections of bristle tufts 5 are provided, wherein also the cross-sectional sizes may be different. This can be borne by corresponding cross-sectional areas on the recesses 18. The shaping of the cross-sectional contour of the individual bristle tufts can then take place in the mold 7 and / or the holding plate 14. Since the device 1 in the exemplary embodiment 2 has bristle magazines 15 lying opposite one another and the slide 17 located transversely to them and the bristles 4 located therein has recesses 18 for separating bristle tufts 5 at its two longitudinal sides, during the production of the bristle fields 2 and / or the bristles 3 bristles of different thickness, quality, flexibility and / or color are combined. The association ratio of such different tufts of bristles to one another can also be preselected by different numbers of recesses 18 on the removal slider 17.

Of course, several bristle magazines 15 or pairs of such magazines 15 and associated removal slide 17 may be provided to the inlet heads 13 of the suction guides 10 to allow an even higher production rate and possibly the feeding of even more forms 7 simultaneously.

It should be mentioned at this point that the supply lines 10 for the bristle tufts 5 from the slider 17 to the molds 7 about 1mm-10mm diameter, z. B. about 2 mm or 5mm inner diameter, depending on how djck the individual bristle tufts are 5. The length of the supply lines 10 may be about 1 m-10m, for example about 5m, as experiments have shown, without any of the sucked bristles in the line 10 remain. Thus, an optimal for the production process assignment of the bristle magazines 15 to the molds 7 can be selected. A further advantageous embodiment of the device 1 can be seen in Fig.4. Accordingly, the molds 7 are arranged on a conveyor or chain belt 24 or the like. Feed means via whose upper run in the feed direction according to the arrow Pf 2 one behind the other the mouth 11 of the supply lines 10, next to a heating or melting station 25 for melting the bristle ends and, if necessary In turn, in the feed direction next to it, a feed device for brush body 26 and / or an ultrasonic welding device 27 or adhesive device are arranged. At the lower run of the belt 24 can be seen the ejection station 28 for the finished brushes. 3

As already mentioned, when filling the mold 7 between this and the mouth 11 of the lines 10 as shown in FIG. 1, a holding and insertion plate 14 is arranged for the bristles 4, the passage hole jngen 6a in the arrangement in which the bristle tufts 5 to a bristle field are summarized and from which the bristles 4 used in the mold protrude when merging with their ends 8. This autlegbare on the form 7 holding plate 14 can dt . consist of the material from which also the brush body 26 is made, so that the welding or bonding with the brush body 26, which is still imminent in Fig. 8 and already performed in Fig. 10, is simpler and more durable possible. It can be seen in Fig. 4 that in front of the station for filling the bristles 4 in the mold 7 is still a work station 29 is arranged, in which the holding plates 14 are fed and placed on the mold 7.

In Fig. 8 is still indicated that this plate 14 may have a suitably circumferential sealing flange 30 which covers the joint between the plate 14 and the recess 31 of the brush body 26 after bonding and so the life of the brush, especially in their use extended as a toothbrush on, because a penetration of detergent u. Like. Be more effectively prevented in this area.

In Fig. 1,6,14 and 15 it can be seen that the Lochungon have 6a in the holding plate 14 on the working ends of the bristles 4 facing away from top depressions 6b, so expand to this top. In these expansions or depressions 6b of the perforations 6a, the fused ends 8 of the bristles 4 of the individual bristle tufts are located after the fusing according to FIG. 6, wherein it is also indicated in FIG. 6 that these depressions 6b lie below the plate surface with the facing one another Edges can merge into one another, so that therefore the fused bristle ends can be partially connected and merged with those of the neighboring tufts in accordance with FIG. In FIGS. 6 and also 10 it can be seen that the webs of the holding plate 14 remaining between adjacent perforations 6a have a lower height than corresponds to the entire plate thickness. Thus, not only the bristles 4 of a bristle tuft 5 know each other at these points of reduced web height, but also the adjacent bristle tufts 5 are fused together, as indicated in FIGS. 6 and 10. Thus, in this solution, the individual bristle tufts are already well secured against pivoting, so that only the individual bristles 4 can be bent out due to their elasticity.

If, at the same time, after the ends 8 of the bristles 4 have melted, the still soft or doughy melt is placed under the negative pressure, which also serves to convey the bristles 4 into the mold 7, this melt can in part lie in the holding plate 14 between the bristles sucked and thus the strength of the anchorage can be further improved.

In Fig. 14 and 15 is still indicated that on the side of the holding plate 14, on which the bristles 4 to be fused with their ends 8 protrude between the perforations 6a projections, protrusions, knobs 33 or the like may be made of fusible material, which can also be melted at the same time with the melting of the bristles and fused with them, so that the connection with the holding plate 14 is even better and more intimate. This applies both when the holding plate 14 is made of the same material as the bristles 4, as well as if another material is provided, which can still mix wholly or partially with the bristle material and causes a stable anchoring of the bristles 4.

If such additional nubs 33 are also melted together, the intermediate spaces recognizable between the fused areas in FIG. 7 can also be filled with molten and again solidified plastic compound. Fig. 9 shows that the Hdlteplatte 14 may also be directly itself the brush body, in which the bristle tufts 5 are inserted and to which they are fused, it is then expedient to complete the side provided with this merge with a cover plate 32 in particular, if only the bristles 4 of the bristle tufts 5 are fused together and not with the neighboring tufts, as shown in FIG. 5.

With the above-described device 1, brushes 3 or bristle fields 2 can be produced, wherein bristle bundles or tufts 5 are filled into the perforations 6 of the molds 7 and then to the ends 8 facing away from the later free working ends of the plastic bristles 4 in the direction shown in FIG. 5 or 6 fused manner are fused, wherein Fig. 5 shows a merger only at the individual tufts 5, Fig. 6 and 7 but a fusion each with the neighboring tufts. The procedure is such that initially the bristle tufts 5 are formed from single bristles 4 by a bristle supply is separated into bristle tufts 5, that then the bristles 4 sucked in tufts, fed to the mold 7 and sucked into the holes 6 of the mold 7 and then fused , In this case, the feeding and filling in the mold in a workstation, the subsequent merging done in a neighboring workstation, so that during the fusing of the bristles already a filling process in a next form 7 can be performed. The bristle tufts 5 are thereby sucked according to the embodiment by the laid on the mold 7, equipped with matching holes 6a holding plate 14, the merging ends 8 of the bristles 4 on the plate 14 survive or at least in one to the top of the plate 14 out 6 b extend (Fig. 6), and that subsequently the bristles 4 are melted together and optionally with those of the neighboring bristle tufts and also with nubs 33 of the holding plate 14. After the bristles 4 have been fused together, the holding plate 14 can be connected to a brush body 26, in particular welded or glued, which in turn can take place after a feed movement in another workstation, while at the preceding workstations the preceding method steps are parallel and simultaneous at a subsequent workstation Shape can be performed. Finally, the bristle field is ejected after the connection with the holding plate 14 by the fusing of the bristles or with the brush body 26 from the mold 7.

The fact that this method and its individual steps simultaneously at different workstations and u.U. can be performed simultaneously in several forms and no longer every single bundle of bristles 5 must be stuffed into the perforation of a brush body, over conventional brush production method significantly increased production speed can be achieved. At the same time a favorable anchoring of the bristles is achieved by the merger and also a convenient connection with a brush body, in case of need not only bristles 4 different halves and shape, but also different holding and shape, but also different colors and with different arrangement at their working ends can be combined.

To produce brushes or bristle fields bristle tufts 5 are formed from single bristles 4 and then tufts filled in holes 6 of half-molds 7 and then fused to the holding ends 8. This is done in an expedient manner in that a bristle magazine 15 with a corresponding bristle supply the bristles 4 are removed and thereby separated into bristle tufts 15, then sucked these bristles 4 in tufts by individual lines 10 associated with them and fed to the mold 7 and thereby in the perforations. 6 the molds 7 are sucked. They can simultaneously be sucked through inserted into the mold 7 or in a recess provided therein holding plate 14, with which they are connected by the subsequent fusion process, so that the connection of the bristles to the brush body 26 is considerably simplified, since such Retaining plate 14 can be well welded or glued to a brush body 26 or even form this brush body 26 itself. It should be mentioned at this point that when merging only each of the individual bristle tufts in the manner shown in Fig. 5 single bristle bundles arise, which instead of a compound with the aid of the support plate 14 to a bristle field also easy

can be used as part of a brush in its manufacture. Thus, the above-described procedure and the above-described and subsequently explained modified device can also be used for the production of bristle bundles for brush and thereby allow a large number in a short time. The device 1 shown in Fig. 14 corresponds in essential parts of the apparatus of FIG. 1 and therefore has for most parts such as the mold 7 and the lines 10 matching reference numerals. The separation of the bristle tufts 5 is done in the manner already described above. In addition, in this case, too, the isolated bristle tufts 5 are fed to the mold or molds 7 with the aid of an air flow which is produced when a negative pressure is applied to the mold 7. It is provided in this embodiment that the mouths 11 of the lines 10 tapers or constrictions 34 with subsequent extension 35, ie in the mouths 11 each have a kind Venturi nozzle is disposed within which the air flow is accelerated due to this cross-sectional constriction. Experiments have shown that under certain circumstances, the bristle tufts 5 are pulled slightly longer during their transport through the lines 10, because initially medium bristles can be transported slightly faster than the applied to the line walls bristles. This can be exploited by an increased insertion speed with the aid of the mentioned constriction 34 in the perforations 6a of the holding plate 14 and 6 of the mold 7, wherein this higher insertion speed also increases the momentum or the kinetic energy of the individual bristles 4, so that even the last bristles Such a convenient design of the bristle supply is possible precisely because of the conveyance with the aid of negative pressure, while a transport mittols compressed air at the entrance to the nozzles to considerable traffic jams could lead through approximately transversely positioned bristles.

Even if one or the other last introduced bristles no longer completely enters the respective perforation 6 of the mold 7, but remains with a considerable part of their length or even completely above the top of the holding plate 14, it can be mitverschmolzen in the subsequent fusion process and thus to increase the strength of the entire produced bristle field, consisting of bristle tufts 5 and the holding plate 14, contribute. In the case of the apparatus 1 recognizable in FIG. 15, the mold 7 with its perforations 6 and the lay-up holding plate 14 with upstanding knobs 33 is again provided, but the bristles or bristle tufts 5 are supplied in a simple manner. For this purpose, a generally designated 37 feeding device for detecting and transporting the bristle tufts 5 is provided in each case to the perforations 6 of the mold 7, the one tufts 5 individually holding slide in this case the already described in the previous devices removal slide 17- and an apertured feed plate 38. On this feed plate 38, the bristle tufts 5 are displaceable by means of the slider 17 transversely to their orientation direction. The feeder plate 38 has passages 39 which are disposed in alignment with the perforations 6 of the mold 7, or are associated with it in flight from the separating and feeding of the tufts V <ynes. Thus, in this embodiment, the bristle tufts 5 can not only be formed and separated in an advantageous manner with the aid of the removal slide 17, but also be supplied virtually directly to the mold 7.

It can be seen in Fig. 15 further, that the mold 7 in turn a vacuum port 9 below a porous, the ends of the perforations 7 containing insert 22, so that in this case by applying a negative pressure, an air flow can be generated, the causes the introduction of the bristles 4 in the holes 6 of the mold 7 or at least supported, since in the illustrated arrangement - as in the above-mentioned embodiments, in addition, the gravity is effective.

While the devices according to FIGS. 1, 4 and 14 can bridge a large distance between the bristle supply and the mold, the device according to FIG. 15 permits a construction with a small footprint.

It should be noted that the bristle tufts 5 may contain a different number of individual bristles 4 and that in the extreme case, only a single bristle 4 can be provided and transported in the manner described in the form and by a holding plate 14. Just in this case, the constriction 34 shown in FIG. 14 may be useful to accelerate such a few or a single bristle 14, but also-as in the embodiment of FIG. 14 -central to introduce themselves into the respective hole 6.

The introduction of only a single bristle 4 in a perforation 6 of the mold 7 is especially favorable, νγβηη relatively thick bristles, possibly with spherically thickened working ends on a brush are desired in the z. B. may be a massage effect in the foreground. Even such a single bristle can be thickened at its end by fusing and connected to the support plate 14. -

Here, too, a fusion with the holding plate 14, be it that of the same material, be it that it is made of a different material than the bristles 4, with the aid of nubs 33 on the holding plate 14 expedient to, as in the embodiments described above, to make a permanent connection between the bristles and the holding plate 14.

In Fig. 16 with respect to the removal slide 17 is a comparison with FIG. 2 modified embodiment shown, but matching parts have even with a changed outer design matching reference numerals. In this case, the extraction slide 17 is rotatable in this embodiment, d. H. it can be rotated when removing the bristles 4 from the or the bristle magazines 15 and when conveying to the insertion openings 12 or the passages 39 and from there again to the respective bristle magazine in a constant rotational direction Pf 4 and thus rotate only with one direction of rotation. Thus eliminating the need for the reciprocable slide 17 shown in FIG. 2 Leerhub, through which the slide 17 with its recesses 18 must be moved back to the bristle magazine 15. Due to this continuous direction of movement and operation as well as the avoidance of a loss of time by such an idle stroke, the feed with bristles and thus the entire workflow can be significantly accelerated. After a partial revolution between the respective removal positions of z. B. 90 °, a holding position for the transfer of the bristles 4 may be provided. It can be seen in Fig. 16 that serving as a removal slide 17 turntable is acted upon by two opposing bristle magazines 15, but at four points open-edged recesses 18 for the bristles 4, so that always on the one hand such recesses 18 in the bristle magazines 15 and on the other are arranged in the area of transfer to the forms out. As in the embodiment of FIG. 2, the open-edged recesses 18 are held closed by a portion of the rotary path by lateral guides 18a to set the bristles.

The rotatable removal slide 17 is a turntable with a circular circumference and a central axis of rotation and the recesses 18 are arranged open edge on the circumference of this turntable. As mentioned, dubei two, but possibly also z. B. four or with correspondingly large circumference of the turntable even more ßorstenmagazine 15 along the circumference of the turntable spaced apart, only between these bristle magazines 15 each enough space for the holding position and the transfer point to the insertion openings 12 or passages 39, respectively lead to the form 7, must be present. Again, the open-edged Ausnehmungan 18 different contours and cross-sections have to form different bristle tufts.
