Definitions

  • the invention relates to a method for producing a brush or a paintbrush, in particular a paintbrush such as a nail polish brush, by fastening at least one bundle of bristles to a support section of the brush or the paintbrush without anchoring.
  • the invention also relates to a device for producing a brush or a paintbrush, by means of which at least one bundle of bristles is fastened to the brush or the paintbrush without anchoring.
  • Anchors are either metal plates or wire loops that lock folded bundles of bristles to a holding section of the brush or paintbrush and cut into the edge of the corresponding opening.
  • the holding section of the brush is the part of the brush body to which at least one bundle of bristles is attached.
  • the holding section is an integral part of the brush body.
  • Another variant provides for the brush body to be made of several parts, so that a type of plate or tube is first produced, to which or in which the bundle of bristles is then attached. This separate part is then connected to the rest of the brush body.
  • the rest of the brush body can already be manufactured and form a separate part, which is then connected to the bristled part, for example by gluing.
  • the bristled part can also be overmolded, whereby the rest of the brush body is then manufactured.
  • the bristle bundle is attached by the openings in the corresponding part with the holding section.
  • the bristle ends are connected to one another at the back, for example by thermal forming, ie melting.
  • This section of the brush is then covered at the back by means of a cover or by means of an overmoulding.
  • Another possibility for fastening without an anchor is to arrange the bristle bundle(s) in an injection moulding tool insert and, after the bristles have been connected at the back, to overmould the bundle(s) at their rear end.
  • the bristle bundles are taken from a magazine in which the bristles are arranged next to each other and are stored under lateral pre-tension.
  • a so-called bundle remover takes an individual bundle from this magazine.
  • a brush manufacturing machine which has a multiple feed for strand-shaped bristle material with a feed device for the bristle strands. Furthermore, a cutting device for bristle bundles and a feed device for feeding the bristle bundles to a device for connecting the bristle bundles to a brush body are provided. Shearing devices for cutting the bristle strands are arranged next to them. The bristle strands are introduced into a bundle carrier and then cut off so that bristle bundles are formed in the bundle carrier. The bristle bundles are then pushed into a perforated plate by a pusher.
  • the EN 10 2009 053 663 A1 discloses a method for the anchorless production of bristle goods.
  • Strand-shaped bristle material is introduced into a bundle carrier and a bristle bundle is then formed by cutting the strand-shaped bristle material with a knife.
  • the bristle bundle is then transported into the bristle body using compressed air.
  • the brush body acts as a holding section for the bristle bundle.
  • the present invention provides a method for producing a brush and an apparatus for producing a brush in which the bristle supply is simplified.
  • the bundle carrier is already the holding section of the brush or paintbrush itself.
  • the holding section is therefore part of the later brush or paintbrush body.
  • the holding section itself can merge into the rest of the brush or paintbrush body as one piece and form a section of it. This is the case, for example, when the entire brush body of a toothbrush, including the head, neck and handle, is manufactured in advance and then stuffed and possibly only overmolded on the back in the head area.
  • the holding section can be a previously manufactured component, for example a plate with one or more openings or a sleeve on a paintbrush. This stuffed component is then part of the later brush or paintbrush body by being subsequently connected to the rest of the brush or paintbrush body, for example by overmolded or by attaching it to another prefabricated part of the body, e.g. the handle.
  • the already cut bristles are not taken from a magazine, but immediately before the production of the brush or paintbrush, they are taken from at least one endless spool and only cut off in the bundle carrier. This means that this cutting of the bristles takes place in the device for producing the brush itself.
  • the fibers are of course preferably arranged parallel in the spool and not twisted together as in a rope.
  • strands can be pulled off several spools at the same time and combined into a common strand. This common strand is then inserted into the opening of the bundle carrier and then cut off.
  • strands can also be pulled from several spools at the same time and pushed into several openings in the bundle carrier and then cut off.
  • several spools can also be combined to form one strand.
  • the strands can be different, i.e. have different fibers in color or cross-section, for example.
  • the bristle bundle can be held on or in the holder section in such a way that it has an arched front bundle end when viewed from the side of the bristles or when viewed from above. This improves the application of the paint, particularly with a nail polish brush.
  • the unwinding of the strand from the spool can be carried out by at least one roller acting on the drawn-off section of the strand.
  • This roller is driven, although of course a non-driven or driven counter-roller can also be present if necessary, so that the strand is clamped between the rollers.
  • rollers for several spools to unwind strands simultaneously.
  • the multiple strands from several spools can be unwound by a driven roller.
  • This roller has sections separated from each other, for example by providing intermediate discs that form rollers between them. Each roller can then be assigned to one strand.
  • the roller or rollers can have a profiled outer surface that engages the strand and changes the cross-sectional shape of the strand and thus the position of the fibers on the output side. This means that an intermediate stage to the final cross-sectional shape of the bristle bundle or the final cross-sectional shape of the bristle bundle can be formed via the profiled outer surface.
  • the strand(s) do not have to be in their final position in the bundle carrier before they are cut. Rather, it is possible to move the bristle bundle further into the bundle carrier towards the front after cutting, for example using a type of stamp or a type of moving plate.
  • the bristle material can be inserted so far into the bundle carrier when it comes from the spool that it already protrudes from the front.
  • the bristle ends protruding from the back can then be attached to the holder section.
  • One way of attaching them is to fuse the bristle ends protruding from the back together after passing through the holder section.
  • the material of the holder section can also be fuse together, although this is not absolutely necessary. However, since the materials of the bristles and the holder section can also be different, it is also optionally possible for only the bristle ends to be fuse together at the back to form a homogeneous section, thus preventing them from being pulled out to the front.
  • the holder section can be attached to a handle, as briefly mentioned above.
  • This handle can be coupled to the bundle carrier, for example, via a snap connection.
  • the brush body (intermediate magazine or plate as part of the complete brush body or brush body itself) has several openings, these can be equipped by one or more coils with bundles of bristles that are then later separated.
  • the bobbin(s) or the brush body are moved in two directions, e.g. with or without the use of an insertion device between the roller and the brush body, in order to achieve a relative movement of these parts. For example, one hole after the other is plugged with a bobbin and after the strand has been inserted it is cut off.
  • strands and spools with different fibers can be used.
  • three spools may be sufficient.
  • Spools can also be switched on or off during a filling process of a brush body with multiple openings when their strand is no longer needed. Furthermore, strands can also be inserted one after the other into the same opening in the insertion device so that it positions different strands one after the other.
  • strands can also be combined if large tufts need to be created in the brush. For example, for a toothbrush with 20 holes, it may be necessary to use 25 spools, where the strands from ten spools are combined into five common strands.
  • the bundle carrier is the holding section of the brush or paintbrush itself, whereby the holding section is a section that merges integrally into the rest of the brush or paintbrush body or is a separate, previously manufactured component that is part of the later bundle carrier.
  • the feeding device can have at least one roller engaging the withdrawn portion of the strand for withdrawing the strand.
  • rollers can be present.
  • sections separated from one another on a roller can also form the rollers.
  • Each roller is assigned to one strand of a spool.
  • a profiled outer surface can be present on the roller or rollers in order to change the cross-sectional profile of the strand on the output side.
  • an insertion device with at least one insertion channel can be provided.
  • the end of the strand is first inserted into this insertion channel and then threaded through.
  • the end of the insertion channel on the opposite side should be opposite the rear mouth of the opening on the bundle carrier, whereby the bundle carrier and insertion device can also be minimally spaced from each other.
  • the insertion device can also be used to align or combine several strands from several coils.
  • the strands of these several coils extend through the insertion device and/or several strands in the insertion device combine to form one strand on the output side.
  • the opening or, depending on whether an introduction device is also provided the introduction device has different cross-sections at the inlet side of the opening or the introduction channel compared to the outlet side.
  • the channel or the opening can narrow in a funnel shape, or several sub-channels can be provided on the inlet side, which then combine to form a common channel on the outlet side.
  • Another possibility is to form several sub-sections on the inlet side, for example like a cloverleaf, which are separated from one another in sections, whereas the opening or the channel on the outlet side then has a completely different cross-sectional shape.
  • the insertion channel or opening on the back can have a different cross-section at the mouth than on the front to make it easier to thread the strand(s) and/or to change the cross-section of the strand(s).
  • the insertion channel or opening can taper from the back to the front mouth and/or the front and back mouths can have different cross-sectional shapes.
  • Cross-sectional shapes means that the shape itself is different, i.e. not just a change from a small circle to a larger circle, for example, or from a small rectangle to a larger rectangle, but that the insertion channel or opening changes, for example, from a circular mouth on the back to an oval or rectangular mouth on the front.
  • the term "different cross-section" includes both changes in the cross-sectional shape and just changes in the cross-sectional area, i.e. from a small rectangle to a larger rectangle.
  • the device according to the invention can also have several spools on which strands are wound and which are combined to form a common strand or which are inserted into separate openings in bundle carriers.
  • an alignment tool can be provided.
  • the shape of the at least one bristle bundle is determined using this alignment tool, with the alignment tool being arranged on the front of the holding section.
  • this alignment tool can be provided with channels or openings that run at an angle and/or have a specific cross-sectional shape (arched, rectangular or the like).
  • the bristle bundle(s) are pushed into the channel(s) or opening(s), thereby retaining a specific shape, and only then are the bristles attached to the holding section, for example by fusing them together on the back or by overmolding them. This list is not exhaustive.
  • the bundle carrier can be an intermediate magazine reused in the device, which is equipped with the at least one cut-to-length bundle of bristles and from which the at least one bundle of bristles is pushed in particular into the holding section and then fastened to the holding section.
  • the intermediate magazine can form an injection molding tool insert, or the bundle(s) of bristles are pushed further from the intermediate magazine into an injection molding tool insert and then finally overmolded.
  • the device can be designed such that the feeding device pushes the severed bundle of bristles further into the holding section so that the bundle of bristles and previously the strand(s) are not already in their final position before cutting.

This may depend on the desired profile of the bristle bundle 16.
  • FIG 4 is shown schematically how the device for producing the brush can be designed.
  • the bristles are not taken from a magazine in which the bristles are already cut to length, but rather endless spools 24 to 28 are used for production, on which strands 30 to 34 of fibers arranged next to one another are rolled up.

  • These strands 30 to 34 are unrolled from the spools 24 to 28, for example by rollers 36 to 38 (and usually also corresponding counter rollers, which are not shown here for the sake of simplicity) engaging the respective strand 30 to 34 and unrolling it.
  • the device for producing the brush has an introduction device 42 between the rollers 36 to 40 and the bundle carrier 14, which is shown in a simplified manner and in which the strands 30 to 34 are combined to form a common strand 44.
  • the introduction device has an introduction channel 46 which has a rear (in Figure 4 visible) and an opposite mouth on the front.
