Abstract
In a system for making bonded belt loops, a layer of thermally activated adhesive material is provided on one side of a strip of interfacing material. The reverse side of a strip of belt loop material is engaged with the side of the strip of interfacing material opposite the adhesive layer. An endless belt is utilized to transport the strip of belt loop material and the strip of interfacing material along support structure and into engagement with a revolving bonded drum. Rotating knives are disposed on opposite sides of the support structure for trimming the strip of belt loop material to a predetermined width. Thereafter a folding apparatus is utilized to fold the opposite edges of the strip of belt loop material around the strip of interfacing material. The bonding drum includes heating apparatus and functions to activate the adhesive layer on the strip of interfacing material. Simultaneously the endless belt engages the folded edges of the strip of belt loop material with the activated adhesive layer, thereby permanently bonding the strip of belt loop material to the strip of interfacing material.
