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. Advancing the strip between the horn and the anvil is accomplished by means of the elements on the strip for continuously producing tapes having a desired number of elements thereon.
