ABSTRACT:
A device for automatically supplying a strip of elastic tape material to a sewing machine under tension. The device uniquely combines a tape supply mechanism, for tractively propelling the tape, and a tape tensioning assembly which guides the tape along a predetermined path of travel while measuring the amount or degree of tape tension. The tape supplied is under the control of the tape tensioning apparatus which may include a mechanism for selectively modulating the degree of tape tension.
