Due to a flange-like expansion of the base section of the support element can be the contact surface between the brush body and the support element be enlarged to loosen the support element even better to prevent.
- the bristle bundles are preferably fastened in the bristle body, whereby the individual bristle bundles are characterized by the respective Extend support elements through. Alternatively, you can the bundles of bristles are only attached to the support elements be, between the bristle bundles and the support elements Group liability is achieved.
- the sleeve section or its outer contour be formed essentially cylindrical.
- the necessary Apply bevels and bends In the preparation of of the support element or elements in a form Specialist for easier removal from the mold the necessary Apply bevels and bends.
- the sleeve section can also be designed in this way be that its wall thickness at the end of use Bristles tapered.
- the bending characteristic of the Systems bristle bundle / support element influenced in the desired manner become.
- the shape of the outer sleeve can meet the requirements a desired bend line of the bristle bundle or individual bristles can be adjusted.
- an integral support element interconnected.
- the brush body can completely on the bristle side Integral support element are covered, resulting in a homogeneous Appearance and a high peel strength of the support elements leads.
- Such an integral support element can also be used manufacture in a particularly efficient manner.
- the support element can have a surface formation for enlargement the interface between the two are provided to to improve the peel strength.
- a corresponding increase in surface area can for example by corrugation on one or both parts.
- the attachment of Grooves, ribs, hole patterns or the like can be given.
- One way is to fold a bundle of bristles and then the folded end by means of an anchor in the brush body to fix.
- the anchor for example a plate-like one Metal or plastic part, can with that looped bristle bundle in a provided on the brush body Opening used, for example, punched.
- the bristles can also be made by that the ends of the bristle bundles to be fastened are melted be so that thickenings form. The thickening are then with brush body material or with support element material overmolded, so that the bristle bundles form-fitting being held.
- the brush can be used in a two-component injection molding process are produced, the brush body made of a hard plastic component and the support elements as a bristle border preferably made of a plastic soft component, for example consist of a thermoplastic elastomer, however can also be made from a hard component. Ideally, between the hard component of the brush body and the support element or the support elements composite adhesion realized. With appropriate material management can brush body and support elements in successive Manufacturing steps made in a single mold become.
- a brush body that can be formed in one piece with the handle of the brush 10 is with a variety of in any way producible blind holes 11 provided.
- Each of them serves Blind holes 11 for receiving a bundle of bristles 20 that a variety of, preferably thin, flexible bristles is made of plastic.
- This bundle of bristles 20 is folded or looped around an anchor 40, see that all bristle ends point in one direction.
- Each Bristle bundle is clawed in the brush body 11
- Anchor 40 clamped in its blind hole 11.
- the anchor is formed as a flat plate, which with respect to the Blind hole 11 essentially upright in the brush body 10 is stamped.
