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.
