Abstract
A portion of a melting or fusing adhesive in the form of a cartridge is melted in a melting chamber and supplied under pressure to an adhesive applying device. The latter includes a melting chamber with a heated facing wall having exit holes therein through which the molten adhesive may be pressed out by a piston movable in the melting chamber by way of a power drive. The starting and stopping of the adhesive supply is controlled by the movement of a work piece past the adhesive applying device.
Claims4
A method for melting and applying fusion adhesive to a work piece in a gluing machine, comprising the steps of:
- supplying the fusion adhesive from a magazine into a melting chamber, pressing said fusion adhesive by power operated feed advance means in the direction and against a heatable melting wall, melting only a zone of the fusion adhesive which rests against said melting wall, supplying the molten adhesive under pressure to an applicator device, and initiating the operation of said feed advance means for the fusion adhesive in response to the movement of said work piece through the gluing machine.
