Kind Code:
Y2
Abstract:
An apparatus (10) for cutting off any defective part of a surface type fastener tape or like strip (F) being fed in a predetermined direction and for splicing the thus created two parts of the strip (F) into a continuous length by forming a fused lap joint of their ends. The strip (F) is fed first through a movable gripping jaw assembly (14) and then through a fixed gripping jaw assembly (12). Disposed between the two gripping jaw assemblies (12, 14), two retractable pairs of cutters (76) cut off any defective part of the strip (F) while the latter is gripped by the jaw assemblies (12, 14), leaving the end portions of the strip (F) protruding from the jaw assemblies (12, 14) toward each other. The relative arrangement of the jaw assemblies (12, 14) is such that the protruding end portions of the strip (F) are offset from each other to an extent approximately equal to the thickness of the strip (F). Thus, upon subsequent linear movement of the movable jaw assembly (14) toward the fixed jaw assembly (12), the one of the two protruding end portions is moved into lapping relation with the other. These lapping end portions are ultrasonically fused together or otherwise united.
