Abstract
In a method for connecting bristles to a bristle carrier, each of which is made of thermoplastic material, at least the ends of the bristles are heated so that a reversal of the molecules from an oriented stretched form to a non-oriented balled form takes place and thereby forms a thickening on the bristle ends, upon which the bristles with their thickened ends are inserted into the melted bristle carrier until the melt of the carrier flows behind the thickened end whereby after hardening of the melt an interlocking shape connection is obtained between the bristles and the bristle carrier which joint may also include, in the case of corresponding work material pairs, a material bonding, the interlocking shape connection being independent of the type of materials used for the two parts.
Claims7
A method for connecting bristles to a bristle carrier both of which are made of thermoplastic material, said method comprising the steps of:
- melting a bundle of such bristles at one end to such an extent that a reversal of their oriented, stretched molecular form takes place converting the molecules to a non-oriented balled form and thereby thickening the bristle ends to form a thickening on said one end of said bundle,
- melting said bristle carrier at a bristle receiving surface,
- forming a recess in the melted material of said bristle carrier for receiving said bristle bundle,
- during the forming of said recess displacing the material of said bristle carrier to form a bead surrounding said recess and extending outwardly from said bristle receiving surface of said bristle carrier, and
- inserting said thickening of said bristle bundle into the melted bristle carrier until the melt of the bristle carrier flows around and thereby encloses said thickening of said bundle.
