Definitions
- the invention relates to a method for producing bristle material for bristle products with various types of plastic bristles, which are produced by extrusion as endless monofilaments.
- bristle goods are understood to mean all products in which more than one type of bristle is processed into brushes, brooms, scrubbers, brushes, brush belts, mats with bristle trimmings, etc.
- Bristle material is understood to mean any composition of bristles of finite length that is processed either directly or after further cutting to form the bristle product.
- the bristles forming the bristle stock are predominantly uniform among themselves, that is to say they consist of the same material and have the same geometric dimensions. There are occasional differences in length. But there are also bristle products known which the bristle stock consists of individual bristle bundles or bristle packs with different types of bristles in the bundle or pack. The diversity lies in particular in the bristle diameter or also in the bristle material. This is primarily intended to use optical effects, but also the different properties of the bristles, in order to produce various effects when the bristle goods are used.
- the best known are mixtures of natural bristles and plastic bristles, with the mixture primarily replacing the expensive natural fibers in part, without having to completely forego the advantageous properties of the natural bristles. Such mixtures are particularly well-known for brushes and brooms.
- Plastic bristles are made from endlessly extruded monofilms.
- the monofilaments are wound up after extrusion. Before winding or in the course of further rewinding, the monofilaments are usually stretched in order to give them the desired bending behavior. The molecular longitudinal orientation achieved during stretching is optionally also fixed by thermal stabilization.
- the monofilaments are then brought together to form strands and cut from the strands so-called bundles, the length of which is a multiple of the length of the later bristles. These bundles enclosed with a sheath are then cut into so-called short cuts which correspond approximately to the length of the bristles.
- the short cuts which are still enclosed by the sheath, then go to the brush production, where the sheath is separated and the bristles are usually transferred to a magazine. Individual bundles are withdrawn from the magazine by division, which are then attached to the carrier by mechanical or thermal methods become .
- the endless monofilaments are processed directly by the spool, in that the monofilament strand, in which the monofilaments are present in a number corresponding to the later bundle or stock, is drawn off directly to the place of manufacture.
- the leading end of the strand is positioned there, optionally also thermally attached to the bristle carrier, and then a length corresponding to the desired bristle length is cut off from the endless strand.
- the aforementioned mixing can be done not perform at all.
- the invention has for its object to provide a method which enables the production of bristle goods with different types of plastic bristles, regardless of which of the two aforementioned methods is used in the manufacture of the bristle goods, and at the same time to cheapen the plastic bristle mixture and to ensure a mixture of defined composition.
- This object is achieved in that the various types of endless monofilaments are brought together immediately after the extrusion to form the mixing strand and the mixing strand is cut to the bristle material required for the manufacture of the bristle products.
- the desired bristle mixture is thus produced by bringing together endless monofilaments. This can be done on the occasion of the production of the continuous monofilaments during winding after extrusion, but also later from the production spools. This makes it possible, in particular, to obtain a defined composition in the mixed strand produced from various types of endless monofilaments, which is retained until the bristles are cut to length or any intermediate dimension.
- the elimination of the manual or mechanical mixing process also results in a saving in invenive facilities and space requirements. Furthermore, undesirable waste of bristle material cannot occur. This allows the highest quality requirements for the finished bristle product to be met while at the same time reducing costs.
- the invention also opens up the possibility, hitherto not given, of different structures and / or to produce profiled bristles in a mixture by combining appropriately structured or profiled endless monofilaments, optionally with smooth monofilaments, to form the mixed strand.
- the endless monofilaments can either be combined individually and directly to form the mixed strand. Instead, it is also possible for two or more strands, each with different types, but identical monofilaments within the strand, to be wound together to form a single mixed strand. This enables the bristle goods manufacturer in particular to keep the wound bristle material in stock and to produce the desired mixture if required.
- An advantageous variant of the method is characterized in that the mixed strand is rewound one or more times. In this way, homogeneous fine mixtures can be produced.
- the principle according to the invention can be implemented in different versions. It can be provided that the various types of endless monofilaments in a composition corresponding to an individual bristle bundle or a bristle bundle of the bristle product
- Mixing strand are brought together and the mixing strand is wound up, and that the bundles or packages are then cut to the desired length of the bristles or a multiple thereof before the mixing strand.
- mixed strands are produced in which the number and properties of the monofilaments are already in the form which is desired in the bristle bundle or bristle pack to be attached to the bristle carrier later.
- This version will be chosen especially when it comes to bundles of larger diameter, be it that the bundle has a correspondingly large number of bristles or such larger diameter. This method is also suitable for the production of bristle packs of larger cross-section.
- This procedure is also suitable for so-called endless processing, in which the unwinding strand is first connected to a carrier with its leading end and the bristles are cut to length from the strand during or after fastening.
- the attachment is usually carried out by thermal methods, namely welding, injection, injection or the like.
- the method can also be carried out in such a way that the different types of monofilaments are brought together and spooled out in a mixing strand in which the monofilaments are uniformly mixed in a number which is a multiple of the number of bristles in a single bristle bundle, and in that from the mixed strand after unwinding coils with a multiple of the length of the bristles are cut to length, that the bundle is enclosed with a sheath and then the covered bundle is cut into short cuts in a length corresponding to the bristles, from which individual bundles of different types of bristles are cut by compartments be preserved.
- the bundles can be fastened mechanically, e.g. the known punching, but also done by gluing with any thermal process.
- endless monofilaments of different diameters and / or materials and / or profiles and / or different surface structures and / or colors can be combined to form a mixed strand, optionally with intermediate winding of thinner strands.
- FIG. 1 shows a view of a plant for producing the bristle material and the finished bristle product in the "in-line” process
- Figure 2 shows a variant of the method according to
- Figure 3 shows several versions of a plant for producing a mixed strand
- FIG. 4 further designs for producing a mixed strand and Figure 5 shows a last variant with coextrusion of different types of monofilaments.
- extruders which are each equipped with multiple nozzles.
- the extruders 1 and 3 work with triple nozzles, the extruder 2 with a quadruple nozzle, this number being only an example of any other, in particular higher number of nozzles.
- the endless monofilaments 4 produced by the extruder 1 are wound up on a spool 5, if appropriate after a stretching section and thermal stabilization.
- a spool 7 is connected downstream of the extruder 2 and a spool 9 downstream of the extruder 3, which spools accommodate the monofilaments 6 leaving the extruder 2 or the monofilaments 8 produced by the extruder 3.
- the monofilaments 4, 6 and 8 can differ, for example, in diameter or material, in color or also in their surface structure or in their transverse or longitudinal profile. They are each brought together in front of the bobbins to form a strand 10, 11 or 12 and these strands are then wound up.
- a single mixing strand 14 is produced by merging these strands and rewinding onto the spool 13, in which the different types of monofilaments are present in a defined mixture.
- the mixed strand 14 is drawn off from the bobbin 13 with various monofilaments and, starting from its leading end, is wrapped with a sheath 15. So-called bundles 16 are cut to length from the wrapped mixed strand 14, from which by further lengths Cutting several short cuts 17 can be obtained. These short cuts are either processed directly into bristle goods or delivered to the bristle goods manufacturer. The short cuts 17 are freed from the sheath at the production site of the bristle goods and, if necessary, are stored in a magazine. Individual bundles 18 are then divided from the stored short cuts and attached to the bristle carrier 19.
- the strand 14 can also be cut to the length of a bundle before the cover 15 is wound up.
- This strand section can, if necessary, be combed out and then the monofilaments are again combined and wrapped in a bundle 16. This is followed by the production of the short cuts in the manner described.
- monofilaments 8 with different cross-sections and / or cross-sectional shapes and / or different colors are produced by the extruder 3 and these are brought together directly on the spool 9 to form a mixed strand.
- This mixed strand with different types of monofilaments in a defined mixture is either drawn off directly from the bobbin 9 or after a rewinding process and transferred directly to the brush production.
- the strand is attached with its leading end to the bristle carrier, for example in a thermal process. In connection or after fastening, the strand is cut to the desired size, as indicated at 20.
- a plurality of coils with identical strands are preferably put together to form a coil set, and all bundles 21 on the bristle carrier 19 are pulled off by pulling off the strands attached at the same time.
- the several coils can also contain mixed strands with monofilaments of different compositions, so that 19 bundles with bristles of different compositions can be fastened to the bristle carrier in a predetermined geometric distribution.
- FIG. 3 shows three extruders 24, 25 and 26 which are used for the coextrusion of various types of endless monofilaments 27 to 32, which differ, for example, in their diameter, color or the like and after winding onto the coils 33, 34 and 35, on which premixing is already taking place, are brought together to form a mixed strand.
- This is indicated in FIG. 5 in another variant, where the different types of monofilaments are spooled directly onto a spool 36 to form a mixed strand.
- FIG. 4a shows an embodiment in which endless monofilaments of different cross sections are generated.
- the extruder 37 thus produces monofilaments 40 with a triangular cross section, which are wound on a spool 41 are produced while the extruder 38 monofilaments 42 of kr-ice-shaped cross section, which are wound on a spool 43.
- the mixed strand of the coils 41, 43 can then be produced by rewinding.
- FIG. 4b shows a variant in which the extruder produces 39 endless monofilaments of various cross-sectional shapes with a corresponding nozzle shape.
- These different types of endless monofilaments 44, 45 are brought together directly on a spool 46, the mixed strand being formed on this spool. However, the mixed strand can also be obtained by rewinding onto a further spool.
