Definitions
- the invention relates to a process for the production of bristle bundles or individual bristles made of plastic for brushes, brooms, brushes or the like.
- endless monofilaments and winding them either directly onto a spool or in a whole or part of the number of bristles in the bundle Number are brought together, the resulting bundle of strands is twisted and this is wound onto a spool from which the monofilament or bundle strand is drawn off cyclically or continuously and cut to the bristle length, and before or after each individual bristle or bristle bundle on the brush or broom -or brush body to be attached.
- plastic bristles offer the advantage that they can be produced from endless monofilaments by extruders or spinning. The monofilaments are then combined into a strand, wrapped in paper or film packaging and cut to the desired bristle length.
- the invention has for its object to further develop the method described above in such a way that the influence of the lack of creep resistance of the plastic is reduced and even after prolonged storage perfect bristles can be obtained.
- This object is achieved in that the monofilament or the twisted bundle strand are wound in the cheese.
- the monofilament or the twisted bundle strand is not wound in the circumferential direction, but with an adjustable pitch on a bobbin with the Erbais that the Radius of curvature of the bundle strand or of the monofilament can be increased considerably compared to a parallel winding with the same size of the coil. Even if this radius of curvature can no longer be canceled by cold flow, it does not interfere with the later processing of the bristle bundles or bristles, since after cutting the length of the individual bristles is small enough to obtain an approximately rectilinear product.
- the method according to the invention has a further considerable advantage. While previously only flange coils could be used in the production of endless bristles, simple flangeless bobbin tubes or bobbin cores can now be used, since a cross wrap has the advantage that the individual bobbins cannot slide off the bobbin.
- the sput core which can be designed in its simplest form as a cardboard sleeve, has a significantly lower weight than a flange coil, so that the ratio of tare weight and net weight is considerably more favorable. The material and transport costs can be reduced considerably.
- the package can also be wound up without a core.
- these self-supporting cross winding the spools are completely saved and the cheaper storage and transportation costs are even greater.
- the procedure is preferably such that the twisted bundle of oil bundles is initially in a parallel position, e.g. on one or more large production spools, wound up, then drawn off from this parallel winding and then wound up in a cheese winding process.
- this allows the manufacture of the bundle strand and the cross winding to be separated from one another by using the parallel winding as a buffer. This also makes it possible, if necessary, to wind up several bundle strands from different production spools onto a spool core using the cross-winding method.
- the method according to the invention also opens up the possibility for the brush, broom and brush industry that the bundle strands or the monofilaments are drawn off from the cross winder in the direction of the winding axis and processed further.
- the take-off takes place tangentially and in cycles, whereby a constant change of acceleration and deceleration of the bundle strands or the individual bristles is necessary.
- the drive of the trigger device and the suspension of the coils is therefore relatively complex.
- the cross wrap produced according to the invention the bundle strands or the individual bristles can be pulled off in the direction of the vetch or parallel to it. This considerably simplifies the bobbin holder and the take-off device.
- the invention is based on a known device which generates one or more extrusion lines tion of endless monofilaments, a device for merging the monofilaments to form a bundle strand and twisting the same, and a winding stand for winding up the bundle strand.
- the device for bringing them together into a bundle strand and for twisting the same is eliminated.
- a bobbin is also not absolutely necessary here, since the monofilaments can also be wound directly onto a bobbin in the cross winding process.
- the above-mentioned device is characterized according to the invention by a twisted bundle strand or the monofilament-receiving cross winder with delivery mechanism and a flange-less, large-diameter flanged bobbin tube arranged thereon. According to the invention, it is also possible to produce a self-supporting cross wrap without a coil sleeve.
- twisting device such as twisting device, cross winder with delivery mechanism, flangeless, cylindrical or conical bobbin tubes and core-free winding are known in the prior art, for which reason a detailed description can be omitted here.
- a winding stand is arranged behind the twisting device, which initially serves to form a parallel winding, and that the bobbin thus produced with a parallel winding can be attached to the supply unit of the cross-winder.
- the invention is based on known brushing, brooming and brushing machines, which extrude one or more receptacles for the coil and take-off devices for the bundle or the monofi I and cutting devices for cutting to bristle length.
- Such machines are characterized according to the invention in that the receptacles are set up on the machines for the storage of bobbin tubes or self-supporting cross windings and that the pulling direction of the withdrawal devices coincides approximately with the axis of the bobbin tubes or the cross bobbin or runs parallel to it.
- a plurality of extruders 1 can be seen, which produce a plurality of monofit endless bristles 2.
- the monofilaments are brought together to form a strand 5, which is drawn off from a cheese winder 6 via a feed mechanism 4.
- a cylindrical bobbin tube 7 is seated on the cheese winder 6, on which the monofilament strand is wound into a cylindrical cheese 8.
- the device shown in FIG. 3 is located in front of the brush, broom or brush machine. It either has, as shown in the upper left part, several horizontally mounted axes for receiving the bobbin tubes 7 or the cross wrap 8 in a horizontal position or, as shown in the lower left part of FIG. 3, several vertical axes for receiving the bobbin tubes 7 or the cross wrap in a vertical position.
- a take-off device 9 is arranged behind the receptacles for the bobbin tubes 7, which pulls the monofilament strand from the bobbin tubes 7, the withdrawal taking place approximately tangentially when the bobbin tubes 7 are stored horizontally, but axially parallel to the cross-winding 8 when stored vertically.
- a cutting device 10 which cuts the monofilament strand intermittently to the desired bristle length, so that the individual bristles on the machine behind it, which is otherwise known, into the body of the implement, e.g. a brush, a brush, a broom or the like. can be used.
- a twisted bundle strand is produced.
- the continuous monofilaments 2 produced by the extruders 1 reach a twisting device 11 via a junction 3 as a parallel strand 5.
- the twisted strand 12 is then twisted in front of this twisting device Coils bocks 13 and a flange coil 14 withdrawn and wound into a parallel winding 15 ( Figure 2a).
- the twisted bundle strand 12 is then drawn off from the parallel winding 15 of the flange spool 14, which is optionally converted into a vertical position, via a delivery mechanism 4 from a cheese winder 6.
- This also has a cylindrical bobbin 7 of large diameter, on which a self-supporting cylindrical cross wrap 8 is produced from the bundle strand 12.
- a conical bobbin tube 16 can also be arranged on the cheese winder 6, so that a conical bobbin 17 is formed (FIG. 2c). Both cross windings 8 and 17 are processed further in the manner shown in FIG. 3, a bristle bundle of slightly twisted individual bristles being obtained behind the cutting device 10.
Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Borstenbündeln oder Einzelborsten aus Kunststoff für Bürsten, Besen, Pinsel od. dgl., indem Endlos-Monofile hergestellt und diese entweder unmittelbar auf eine Spule aufgewickelt oder in ei ner ganz oder tei Isweise der Borstenzahl im Bündel entsprechenden Anzahl zusammengeführt werden, der entstehende Bündel strang verdrillt und dieser auf eine Spule aufgewickelt t wird, von der die Monofile bzw. der Bündelstrang taktweise oder kontinuierlich abgezogen und auf Borstenlänge abgeschnitten, und zuvor oder danach jede Einzelborste bzw. jedes Borstenbündel am Bürsten-, Besen-oder Pinselkörper befestigt werden.The invention relates to a process for the production of bristle bundles or individual bristles made of plastic for brushes, brooms, brushes or the like. By producing endless monofilaments and winding them either directly onto a spool or in a whole or part of the number of bristles in the bundle Number are brought together, the resulting bundle of strands is twisted and this is wound onto a spool from which the monofilament or bundle strand is drawn off cyclically or continuously and cut to the bristle length, and before or after each individual bristle or bristle bundle on the brush or broom -or brush body to be attached.
Die Herstellung von Borsten und deren Verarbeitung in der Bürsten-, Besen- und Pinselindustrie erfolgt seit Jahrzehnten im wesentlichen unverändert. Wie bei der Verarbeitung von Natur borsten, muß auch bei Kunststoffborsten - mit Ausnahme dort, wo nur Einzelborsten eingesetzt werden - zunächst ein Bündel hergestellt werden, in welchem die Borsten in der gewünschten Anzahl vorliegen. Dieses Borstenbündel wird dann in den Bürsten-, Besen- oder Pinselkörper eingesetzt und an diesem befestigt, z.B. durch Stopfen, Kleben, Schweißen (bei Kunststoffborsten), Kitten od. dgt. Kunststoffborsten bieten dabei verarbeitungstechnisch den Vorteil, daß sie aus Endlos-Monofilen im Wege des Extrudi erens oder Spinnens hergestellt t werden können. D i e Monofile werden dann zu einem Strang zusammengefaßt, dieser in eine Papier- oder Folienverpackung eingehüllt und auf die gewünschte Borstenl änge zugeschnitten.The manufacture of bristles and their processing in the brush, broom and brush industry has been essentially unchanged for decades. As with the processing of natural bristles, also with plastic bristles - with the exception of where only single bristles are used - a bundle must first be made in which the bristles in the desired number. This bundle of bristles is then inserted into and attached to the brush, broom or brush body, for example by plugging, gluing, welding (in the case of plastic bristles), kittens or the like. In terms of processing technology, plastic bristles offer the advantage that they can be produced from endless monofilaments by extruders or spinning. The monofilaments are then combined into a strand, wrapped in paper or film packaging and cut to the desired bristle length.
Bei der Verarbeitung in der Bürsten-, Besen- und Pinselindustrie muß dann das Borstenbündel von Hand von seiner Verpackung befreit und fortlaufend in das Magazin der Bürsten-, Besen- oder Pinselmaschine eingegeben werden. Damit konnte zwar - gegenüber Naturborsten - eine erhebliche Vereinfachung und Verbilligung bei der Herstellung der Borsten erreicht werden, ihre Verarbeitung jedoch blieb unverändert kostenaufwendig. So muß z.B. das Maschinenpersonal zwischen 15 und 30 % der Zeit - je nach Verfahren - für die Versorgung der Maschine mit Borsten aufwenden.When processing in the brush, broom and brush industry, the bundle of bristles must then be freed of its packaging by hand and continuously inserted into the magazine of the brush, broom or brush machine. Although this - compared to natural bristles - made it considerably easier and cheaper to manufacture the bristles, their processing remained costly. For example, the machine personnel spend 15 to 30% of the time - depending on the procedure - for supplying the machine with bristles.
Seit vielen Jahren ist man bemüht, diesen aufwendigen Verarbeitungsgang zu sparen und statt dessen Endlosborsten unmittelbar zu verarbeiten. Es wird dabei so vorgegangen, daß bei der Borstenherstellung ein Bündelstrang aus Endlos-Monofilen verdrillt und auf einer Flanschspule in Parallellage aufgewickelt wird. Durch das Verdrillen des Bündelstrangs wird eine Schlaufenbildung vermieden. Die Flanschspul e mit dem Parallelwickel wird dann an den Bürsten- bzw. Besenhersteller geliefert. Die Bürsten- bzw. Besenmaschine besitzt eine Aufnahme für die Flanschspule, von der der Bündelstrang etwa tangential und taktweise abgezogen und einer Schneideinrichtung zugeführt wird, die den Bündelstrang auf die gewünschte Borstenlänge ablängt. Das einzelne Borstenbündel gelangt dann direkt in die Stopfwerkzeuge zur Befestigung am Bürsten-oder Besenkörper. Es sind mehrere Maschinen zur Verarbeitung solcher Endlosborsten entwickelt worden. Derartige Lösungen haben sich aber in der Praxis nicht durchgesetzt.For many years, efforts have been made to save this complex processing step and instead to process endless bristles directly. The procedure is such that a bundle of endless monofilaments is twisted during bristle production and wound up in parallel on a flange spool. Loop twisting is avoided by twisting the bundle strand. The flange spool with the parallel winding is then delivered to the brush or broom manufacturer. The brush or broom machine has a receptacle for the flange spool, from which the bundle strand is drawn off approximately tangentially and intermittently and fed to a cutting device which cuts the bundle strand to the desired bristle length. The single bundle of bristles then goes directly into the tamping tools for attachment to the brush or broom body. Several machines for processing such endless bristles have been developed. However, such solutions have not become established in practice.
Verfahren der zuvor geschi lderten oder ähnl i chen Art haben den Nachtei daß bei vertretbarer Baugröße und handhabungsf ähigem Gewicht der Flanschspulen deren Durchmesser nicht allzu groß werden darf, um eine ausreichende Länge unterbringen zu können. Dies führt dazu, daß der Bündelstrang bzw. die Monofile vor allem im inneren Bereich der Flanschspule mit einem vergleichsweise kl einen Krümmungsradius aufgewickelt t werden muß. Da annähernd jeder Kunststoff, vor allem aber die für Borsten eingesetzten Kunststoffe keine ausreichende Kriechfestigkeit besitzen bzw. Kaltfluß-Erschei nungen zeigen, führt insbesondere eine längere Lagerung auf der Spule zu einer bleibenden Krümmung, die durch die Rückstellkräfte der Borste nicht überwunden werden kann. Das geradlinige Ausrichten der Borste ist praktisch unmöglich. Es dürfen deshalb solche Spu-Ien zwischen dem Wickel vorgang und der Verarbei tung ni cht allzu lange gelagert werden.Processes of the previously described or similar type have the disadvantage that, with an acceptable size and manageable weight of the flange coils, their diameter must not be too large in order to accommodate a sufficient length. This leads to the fact that the bundle strand or the monofilaments must be wound up with a comparatively small radius of curvature, especially in the inner region of the flange coil. Since almost every plastic, but especially the plastics used for bristles do not have sufficient creep resistance or show cold flow phenomena, longer storage on the coil in particular leads to a permanent curvature which cannot be overcome by the restoring forces of the bristle. Aligning the bristle in a straight line is practically impossible. It is therefore not allowed to store such spools between the winding process and the processing for too long.
Der Erfindung liegt die Aufgabe zugrunde, das eingangs beschriebene Verfahren dahingehend weiterzuentwickeln, daß der Einfluß der mangelnden Kriechfestigkei t des Kunststoffs reduziert und auch nach längerer Lagerung noch einwandfreie Borsten erhal ten werden können.The invention has for its object to further develop the method described above in such a way that the influence of the lack of creep resistance of the plastic is reduced and even after prolonged storage perfect bristles can be obtained.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Monofile bzw. der verdrillte Bündel strang im Kreuzspul verfahren aufgewickelt werden.This object is achieved in that the monofilament or the twisted bundle strand are wound in the cheese.
Beim Kreuzspulverfahren wird das Monofil bzw. der verdrillte Bündelstrang nicht in Umfangsrichtung, sondern mit einer einstellbaren Steigung auf einem Spulenkern aufgewickelt mit dem Erbais, daß der Krümmungsradius des Bündelstrangs bzw. des Monofils bei gleicher Baugröße der Spule gegenüber einem Parallelwickel erheblich vergrößert werden kann. Selbst wenn dieser Krümmungsradius durch Kaltfluß nicht mehr aufhebbar sein sollte, stört di es bei der späteren Verarbeitung der Borstenbündel bzw. Borsten nicht, da nach dem Zuschneiden die Länge der einzelnen Bor ste klein genug ist, um ein annähernd geradliniges Erzeugnis zu erhalten.In the cheese winding process, the monofilament or the twisted bundle strand is not wound in the circumferential direction, but with an adjustable pitch on a bobbin with the Erbais that the Radius of curvature of the bundle strand or of the monofilament can be increased considerably compared to a parallel winding with the same size of the coil. Even if this radius of curvature can no longer be canceled by cold flow, it does not interfere with the later processing of the bristle bundles or bristles, since after cutting the length of the individual bristles is small enough to obtain an approximately rectilinear product.
Darüber hinaus bringt das erfindungsgemäße Verfahren einen weiteren beachtlichen Vorteil. Während bisher bei der Herstellung von Endlosborsten ausschließlich Flanschspulen eingesetzt werd en konnten, lassen sich nun einfache flanschlose Spulenhülsen bzw. Spulenkerne verwenden, da ein Kreuzwickel den Vorteil hat, daß die einzelnen Wickel lagen von der Spule nicht abrutschen können. Der Sputenkern, der in seiner einfachsten Ausführung als Papphülse ausgebildet sein kann, weist ein wesentlich geringeres Gewicht als eine Flanschspule auf, so daß sich das Verhältnis von Tara- und Nettogewicht erheblich günstiger darstellt. Die Material- und Transportkosten lassen sich damit beachtlich reduzieren. Untersuchungen in der Praxis haben ergeben, daß beispielsweise di e Kosten der Spule gegenüber herkömmlichen Flanschspul en nur etwa ein Drittel betragen, wobei zugleich bis zum achtfachen Borstengewicht untergebracht werden kann. Gleichzeitig ergi bt sich gegenüber den Flanschspulen ein erheblich geringerer Raumbedarf, besonders bei der Lagerung und dem Transport der Leerspulen, insbesondere wenn die Spulenhülsen konisch gestaltet werden.In addition, the method according to the invention has a further considerable advantage. While previously only flange coils could be used in the production of endless bristles, simple flangeless bobbin tubes or bobbin cores can now be used, since a cross wrap has the advantage that the individual bobbins cannot slide off the bobbin. The sput core, which can be designed in its simplest form as a cardboard sleeve, has a significantly lower weight than a flange coil, so that the ratio of tare weight and net weight is considerably more favorable. The material and transport costs can be reduced considerably. Practical studies have shown that, for example, the cost of the coil compared to conventional flange coils is only about a third, and at the same time it can accommodate up to eight times the bristle weight. At the same time, compared to the flange coils, there is a considerably smaller space requirement, particularly when storing and transporting the empty coils, especially if the coil sleeves are conical.
Das Kreuzspul verfahren läßt erfindungsgemäß auch ein Aufwickeln ohne Spul enkern zu. Bei diesen selbsttragenden Kreuzwickeln werden die Spulen völlig eingespart und die Verbilligung der Lagerung und Transportkosten ist noch größer.According to the invention, the package can also be wound up without a core. With these self-supporting cross winding, the spools are completely saved and the cheaper storage and transportation costs are even greater.
Durch den größeren Spuleninhalt werden sowohl die Laufzeiten beim Aufwickeln in der Borstenfertigung, als auch beim Abwickeln in der Bürsten-, Besen- und Pinselfertigung erheblich verlängert, so daß die Spulen weniger häufig ausgewechselt werden müssen.Due to the larger spool content, both the runtimes during winding in bristle production and during unwinding in brush, broom and brush production are considerably extended, so that the spools do not have to be replaced as often.
Bei dem erfindungsgemäßen Verfahren wi rd vorzugswei se so vorgegangen, daß der oder die verdrillten Bünde lstränge zunächst in Parallellage, z.B. auf eine oder mehrere große Produktionsspulen, aufgewickelt, daraufhin von diesem Parallelwickel abgezogen und anschliessend im Kreuzspulverfahren aufgewickelt werden. Dadurch lassen sich in verfahrenstechnischer Hinsicht die Herstellung des Bünd el strang s und das Kreuzwickeln voneinander trennen, indem als Zwischenspeicher der Parallelwickel dient. Dies ermöglicht auch, im Bedarfsfall mehrere Bündel stränge von verschiedenen Produktionsspulen auf einen Spulenkern im Kreuzspulverfahren aufzuwickeln.In the method according to the invention, the procedure is preferably such that the twisted bundle of oil bundles is initially in a parallel position, e.g. on one or more large production spools, wound up, then drawn off from this parallel winding and then wound up in a cheese winding process. In terms of process engineering, this allows the manufacture of the bundle strand and the cross winding to be separated from one another by using the parallel winding as a buffer. This also makes it possible, if necessary, to wind up several bundle strands from different production spools onto a spool core using the cross-winding method.
Das erfindungsgemäße Verfahren eröffnet für die Bürsten-, Besen-und Pinselindustrie ferner die Möglichkeit, daß der oder die Bündelstränge bzw. die Monofile von dem Kreuzwickel in Richtung der Wickelachse abgezogen und weiterverarbeitet werden. Bei herkömmlichen FI anschspulen erfolgt der Abzug tangential und taktweise, wobei ein ständiger Wechsel von Beschleunigung und Verzögerung der Bündelstränge bzw. der Einzelborsten notwendig ist. Der Antrieb der Abzugseinrichtung und die Aufhängung der Spulen ist deshalb relativ aufwendig. Durch den erfindungsgemäß erzeugten Kreuzwickel können die Bündelstränge bzw. die Einze lborsten in Richtung der Wicke lachse bzw. parallel dazu abgezogen werden. Damit vereinfachen sich die Spul enhalterung und die Abzugseinrichtung erheblich.The method according to the invention also opens up the possibility for the brush, broom and brush industry that the bundle strands or the monofilaments are drawn off from the cross winder in the direction of the winding axis and processed further. In the case of conventional RW windings, the take-off takes place tangentially and in cycles, whereby a constant change of acceleration and deceleration of the bundle strands or the individual bristles is necessary. The drive of the trigger device and the suspension of the coils is therefore relatively complex. By means of the cross wrap produced according to the invention, the bundle strands or the individual bristles can be pulled off in the direction of the vetch or parallel to it. This considerably simplifies the bobbin holder and the take-off device.
Zur Durchführung des Verfahrens geht die Erfindung von einer bekannten Vorrichtung aus, die aus ein oder mehreren Extrusiionsstraßen zur Erzeugung von Endlos-Monofilen, einer Einrichtung zum Zusammenführen der Monofile zu einem Bündelstrang und zum Verdrillen desselben sowie einem Spulbock zum Aufwickeln des Bündel strangs besteht. Bei Monofilen entfällt die Einrichtung zum Zusammenführen derselben zu einem Bündelstrang und zum Verdrillen desselben. Hier ist auch nicht unbedingt ein Spulbock erforderlich, da die Monofile auch direkt im Kreuzspulverfahren auf einen Spulenkern aufgewickelt werden können. Die zuvor genannte Vorrichtung zeichnet sich erfindungsgemäß aus durch eine den verdrillten Bündel strang oder die Monofile aufnehm ende Kreuzspulmaschine mit Lieferwerk und eine darauf angeordnete, den Kreuzwickel aufnehmende, flanschlose Spulenhülse großen Durchmessers. Erfind ungsgemäß i st dabei auch die Herstel lung ei nes selbsttragenden Kreuzwickels ohne Spulenhülse möglich.In order to carry out the method, the invention is based on a known device which generates one or more extrusion lines tion of endless monofilaments, a device for merging the monofilaments to form a bundle strand and twisting the same, and a winding stand for winding up the bundle strand. In the case of monofilaments, the device for bringing them together into a bundle strand and for twisting the same is eliminated. A bobbin is also not absolutely necessary here, since the monofilaments can also be wound directly onto a bobbin in the cross winding process. The above-mentioned device is characterized according to the invention by a twisted bundle strand or the monofilament-receiving cross winder with delivery mechanism and a flange-less, large-diameter flanged bobbin tube arranged thereon. According to the invention, it is also possible to produce a self-supporting cross wrap without a coil sleeve.
Die erfindungsgemäß eingesetzten Einrichtungen, wie Verdrilleinrichtung, Kreuzspulmaschine mit Lieferwerk, flanschlose, zylindrische oder konische Spulenhülsen sowie ein kernfreies Wickeln sind im Stand der Technik bekannt, weshalb eine nähere Beschreibung hier unterbleiben kann.The devices used according to the invention, such as twisting device, cross winder with delivery mechanism, flangeless, cylindrical or conical bobbin tubes and core-free winding are known in the prior art, for which reason a detailed description can be omitted here.
Mit Vorteil ist bei der zuvor geschilderten Vorrichtung vorgesehen, daß hinter der Verdrilleinrichtung ein Spulbock angeordnet ist, der zunächst zur Bildung eines Parallelwickels dient, und daß die solchermaßen hergestellte Spule mit Parallelwickel am Lieferwerk der Kreuzspulmaschine anbringbar ist. Hiermit lassen sich die Herstel lung der Endl os-Monofile u nd die Erzeugung des Kreuzwickels räumlich und zeitlich voneinander trennen, was in verfahrenstechnischer Hinsicht einige Vorteile bietet.It is advantageously provided in the previously described device that a winding stand is arranged behind the twisting device, which initially serves to form a parallel winding, and that the bobbin thus produced with a parallel winding can be attached to the supply unit of the cross-winder. This allows the manufacture of the endless monofilaments and the generation of the cross wrap to be separated from one another in terms of space and time, which offers a number of advantages in terms of process technology.
Für die Weiterverarbeitung des Kreuzwicke Is geht die Erfindung von bekannten Bürsten-, Besen- und Pinselmaschinen aus, di e eine oder mehrere Aufnahmen für die Spule, Abzugseinrichtungen für den Bündel strang bzw. di e Monofi I e sowi e Schnei dei nri chtungen zum Ablängen auf Borstenlänge aufweisen. Solche Maschinen zeichnen sich erfindungsgemäß dadurch aus, daß die Aufnahmen an den Maschinen zur Lagerung von Spulenhülsen bzw. von selbsttragenden Kreuzwickeln eingerichtet sind und daß die Zugrichtung der Abzugseinrichtungen mit der Achse der Spulenhülsen bzw. des Kreuzwickels etwa zusammenfällt oder parallel zu dieser verläuft.For the further processing of the cross wrap Is, the invention is based on known brushing, brooming and brushing machines, which extrude one or more receptacles for the coil and take-off devices for the bundle or the monofi I and cutting devices for cutting to bristle length. Such machines are characterized according to the invention in that the receptacles are set up on the machines for the storage of bobbin tubes or self-supporting cross windings and that the pulling direction of the withdrawal devices coincides approximately with the axis of the bobbin tubes or the cross bobbin or runs parallel to it.
Auch diese Bautei le der erfindungsgemäßen Vorrichtung sind für sich auf anderen Einsatzgebieten bekannt, so daß sich eine detaillierte Beschreibung und zeichnerische Darstellung erübrigt.These components le of the device according to the invention are known per se in other areas of application, so that a detailed description and graphic representation is unnecessary.
Insgesamt schafft das erfindungsgemäße Verfahren für die Bürsten-, Besen- und Pinsel i ndustri e di e Voraussetzungen für ei ne vol lautomatische Fort tigung.Overall, the method according to the invention for the brush, broom and brush industries creates the prerequisites for a completely Lautomatic continuation.

Hinter den Aufnahmen für die Spulenhülsen 7 ist eine Abzugeinrichtung 9 angeordnet, die den Monofilenstrang von den Spulenhülsen 7 abzieht, wobei der Abzug bei horizontaler Lagerung der Spulenhülsen 7 etwa tangential, bei vertikaler Lagerung hingegen achsparallel zum Kreuzwickel 8 erfolgt. Hinter dem Abzugswerk 9 ist eine Schneideinrichtung 10 angeordnet, die den Monofilenstrang taktweise auf die gewünschte Borstenlänge abschneidet, so daß die Einzelborsten an der dahinter angeordneten, im übrigen aber bekannten Maschine in den Körper des Arbeitsgerätes, z.B. einer Bürste, eines Pinsels, eines Besens od.dgl. eingesetzt werden können.The device shown in FIG. 3 is located in front of the brush, broom or brush machine.
