Abstract: Brassiere tapes having a body portion and a pair of overlapping tabs extending outwardly therefrom are manufactured by providing a continuous strip of material for the tapes having fastener elements spaced along the strip and layers in the body portion and in each of the tabs weldable with ultrasonic vibratory energy. The tabs are separated physically from each other such that the individual layers in the strip may be simultaneously severed and welded across the body portion and the tabs when interposed between ultrasonically vibrating horn and anvil devices, except that the tabs which are physically separated from each other are not welded to each other. Compliant means for mounting of the anvil is provided so that the cutting edge for severing the tapes from the strip which is associated with the anvil is not readily dulled by the repetitive contacting engagement of the horn and anvil surfaces in the operative position.

Abstract: Brassiere tapes having a body portion and a pair of overlapping tabs extending outwardly therefrom are manufactured by providing a continuous strip of the tape material having elements spaced there along and layers at least in the body portion-forming part thereof. The material is weldable with ultrasonic vibratory energy, and the tabs are separated physically from each other while simultaneously maintained in acoustical energy coupling relation to each other, such that the individual layers of material in the strip are welded together across the body portion of a tape defined thereby and the tabs are individually welded along an edge but not welded together when interposed between an ultrasonically vibrating horn and an anvil. The strip is advanced on an intermittent basis between the horn and the anvil by the elements for continuously producing tapes having a desired number of elements thereon.
