Definitions

  • the invention relates to a method for producing Bristle material for bristle products with various types Plastic bristles that are extruded as continuous monofilaments be generated.
  • bristle goods are understood all products where more than one type of Bristles for brushes, brooms, scrubbers, brushes, brush tapes, Mats with bristle trim etc. can be processed.
  • Bristle material is any composition of Bristles of finite length understood that either immediately or after further cutting to the bristle goods is processed.
  • bristle goods are bristle trimmings forming bristles uniform among themselves, so exist made of the same material and have the same geometric Dimensions on. Occasionally there are differences in the length. But there are also bristle products known which the bristle trim from individual bristle bundles or also bristle packs with different types of bristles in the Bundle or package exists (see FR-A-1134245). The diversity lies especially in the bristle diameter or in the bristle material. First and foremost, optical effects, but also the different properties of the bristles be used in order to use different types of bristle goods Produce effects.
  • Plastic bristles are made from endlessly extruded monofilaments prepared (cf. generic EP-A-0 086 412).
  • the monofilaments are made after extrusion spooled. Before winding or as part of another As a rule, the monofilaments are stretched, to give them the desired bending behavior to lend.
  • the molecular longitudinal orientation achieved during stretching is optionally replaced by thermal Stabilize fixed.
  • the monofilaments then become strands merged and from the strands so-called bundles cut to length, the length of which is a multiple of the length of the later bristles. These are enclosed in an envelope Bundles then become so-called short cuts trimmed approximately the length of the bristles correspond.
  • the ones still enclosed by the shell Short cuts then go to brush production, where the Shell separated and the bristles usually on Magazine to be handed over. From the magazine through Compartments peeled off individual bundles, which are then attached to the carrier attached by mechanical or thermal processes become.
  • the leading end of the strand is positioned there, optionally also thermally on the bristle carrier attached and then one of the desired bristle length cut the appropriate length from the endless strand.
  • the invention has for its object a method to create using the manufacture of bristle goods allows different types of plastic bristles, namely regardless of which of the above two procedures applied in the manufacture of the bristle goods and the plastic bristle mixture at the same time cheaper and a mixture of defined composition to ensure.
  • This object is achieved in that different types of endless monofilaments in the for the finished Bristle goods desired composition in the direction their longitudinal extension merged into a mixed strand are and the mixed strand is wound up, and that of the mixed strand for the manufacture of Bristle material required bristle material is cut to length.
  • the desired bristle mixture is thus brought together generated by endless monofilaments. This may be the case the manufacture of the continuous monofilament during winding extrusion, but also later from the production spools happen down. This makes it special possible, in the mixed strand generated from different types Endless monofilaments to a defined composition get that until the bristles are cut to length Final dimension or any intermediate dimension is retained. By eliminating the manual or mechanical mixing process there is also a saving in investment Facilities and space requirements. Furthermore, it cannot unwanted waste of bristle material. In order to can be the highest with simultaneous cost reduction Meet the quality requirements for the finished bristle goods.
  • the invention also does not open up to now given possibility, differently structured and / or to produce profiled bristles in a mixture, by appropriately structured or profiled Endless monofilament, possibly with smooth monofilament the mixed strand are brought together.
  • appropriately structured or profiled Endless monofilament possibly with smooth monofilament the mixed strand are brought together.
  • mechanical or manual mixing can be from such structured or profiled bristles do not produce defined mixtures, as such bristles tend to segregate or not at all let mix.
  • the endless monofilaments can either be single and immediate are brought together to form the mixed strand. Instead it is also possible that two or more strands with each different, but within the strand same endless monofilaments to a single mixed strand be spooled together. This is made possible in particular the bristle goods manufacturer, the wound bristle material to keep in stock and the required mixture if necessary to manufacture.
  • An advantageous variant of the method stands out characterized in that the mixed strand one or more times is rewound. In this way, homogeneous Make fine mixtures.
  • the principle of the invention can be different Realize executions. So it can be provided that the various endless monofilaments in one individual bristle bundle or a bristle pack of Bristleware corresponding composition to one Mixed strand are merged and the mixed strand is wound up, and then before the mixed strand the bundles or packages in the desired length of the Bristles or a multiple thereof can be cut to length.
  • mixed strands are generated, in which the monofilaments in number and quality already have the shape as it will be on the bristle carrier later bristle bundle or bristle pack to be fastened are desired.
  • This version will be chosen especially if it is a bundle of larger diameter, either that the bundle has a correspondingly large number of bristles or has such larger diameter. Also for them Manufacture of bristle packs of larger cross-section this method is suitable.
  • This procedure is also suitable for the so-called Endless processing, in which the unwound strand with its leading end first connected to a carrier will and during or after fastening the Bristles are cut to length from the strand.
  • the attachment usually takes place by thermal processes, namely welding, injection, beating or the like.
  • the method can be done in the same way be carried out that the different types of monofilaments are brought together in a mixed strand and spooled out, in which the monofilaments evenly mixed in one Number that are a multiple of the number of Bristles in a single bundle of bristles, and that of the mixed strand after unwinding bundles with a multiple the length of the bristles are cut to length that the Bund is wrapped with a sheath and then the covered waistband into short cuts in one of the bristles appropriate length is cut from which individual Bundles of different types of bristles by dividing be preserved.
  • the attachment of the bundle can be mechanical Manner, e.g. the well-known punching, by gluing but also with any thermal process.
  • continuous monofilaments can be produced of different diameters and / or materials and / or profile and / or different surface structure and / or color to a mixed strand, if necessary with the intermediate winding of thinner strands.
  • extruders With 1, 2 and 3 extruders are indicated, each with Multiple nozzles are equipped.
  • the endless monofilaments 4 generated by the extruder 1 - if necessary after a stretch and a thermal stabilization - wound on a spool 5.
  • the extruder 2 is a coil 7 and the extruder 3 is followed by a coil 9, which the the extruder 2 leaving monofilament 6 or from Extruder 3 record monofilaments 8 generated.
  • the monofilaments 4, 6 and 8 can, for example, in the Diameter or material, in color or in their surface structure or their transverse or longitudinal profile differentiate. They are each in front of the coils a strand 10, 11 or 12 merged and there will be these strands then wound up.
  • each with different types Monofilament is made by merging these strands and rewinding onto the coil 13 a single mixing strand 14 generated in which the different types of monofilaments defined mixed.
  • the mixed strand 14 with different types Monofilament subtracted and -from its leading Outgoing - wrapped with a sleeve 15.
  • Lengths are wrapped by the mixed strand 14 so-called bundles 16 cut to length, from which by further Cutting several short cuts 17 can be obtained.
  • This Short cuts either become bristle goods immediately processed or to the manufacturer of the bristle goods delivered.
  • the short cuts 17 are at the manufacturing site the bristle goods are freed from the casing and, if necessary magazine.
  • the short cuts that have been stored in magazines then separate bundles 18 and on the bristle carrier 19 attached.
  • the Strand 14 also before winding the sleeve 15 to length be cut off from a covenant.
  • This strand section can be combed out if necessary and then the monofilaments are again combined into a bundle 16 and envelops. This is followed by the production of the Short cuts in the manner described.
  • FIG. 4a shows an embodiment in which Endless monofilaments of different cross-sections are created become.
  • the extruder thus produces 37 monofilaments 40 with a triangular one Cross section wound on a spool 41 be while the extruder 38 monofilaments 42 of circular Cross-section generated, which wound on a coil 43 become.
  • the mixed strand can then be of the coils 41, 43 generated by rewinding.
  • Figure 4b shows one Variant in which the extruder 39 continuous monofilaments of different Cross-sectional shape with a corresponding Nozzle shape created.
  • These different types of endless monofilaments 44, 45 are brought together directly on a coil 46, the mixed strand being formed on this coil becomes. However, the mixed strand can also be rewound can be obtained on another coil.
