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.
Claims14
An apparatus for melting and mechanically applying a fusion adhesive to a workpiece in a gluing machine, comprising chamber means (16, 35), a fusion adhesive supply aperture (30) in said chamber means, heatable melting wall means (22, 36) forming part of said chamber means at one end thereof, said heatable melting wall means comprising outlet holes for the molten fusion adhesive, said apparatus further comprising supply piston means movably supported inside said chamber means, feed unit means operatively connected to said supply piston means, and fusion adhesive magazine means for holding fusion adhesive units (28) operatively located relative to said supply aperture (30) for supplying a fusion adhesive unit from said magazine means through said supply aperture into said chamber means when said supply piston means is in a retracted position whereby said supply piston means is enabled to press fusion adhesive against said heatable melting wall means when said supply piston means are moved out of said retracted position to melt only that quantity of adhesive which is presently needed.
