ABSTRACT:
In a system (300) for prefabricating strings of pocket welts on a continuous basis, the assembly proceeds along one side of a table (12). Adhesive backed fabric tape (48) from a supply reel (50 ) is indexed into a bonding station where sections of fabric (154) are positioned by photoelectric sensors (306, 308) and adhesively attached to the fabric tape. The fabric tape (48) is indexed to an adhesive application station (310) where an adhesive layer is bonded to the fabric tape and the backing layer separated at a backing separator (356). The fabric tape (48) then moves to a bonding/folding station (420) where the fabric pieces are folded and bonded to form the welts. Forward and rearward centering assemblies (424,426) employ front and rear positioning fingers (428, 430) to center the fabric tape in the folding/bonding station (420).
