Tension equalizer

摘要

Apparatus for coordinating the transfer of two continuous cords or strips includes a first roll for delivering a first cord or strip, a second roll for delivering a second cord or strip, a drive for the first roll, a drive capable of operating the second roll at speeds different from that of the first roll, and a tension-detecting control arrangement for detecting changes in the tension of the cord or strip being delivered by the first roll and changing the speed of the second roll in response thereto.
