ABSTRACT:
A tensioning device to control the dispensing of a large roll of ribbon or tape under a uniform tension as the roll becomes smaller in diameter. The tensioning device comprises a rotatably supported spool that is fixedly positioned and an adjustable roller mounted to a pivot arm, whereby the roller is positioned contiguously with respect to the fixed spool, the ribbon or tape being interposed therebetween. The roller includes an outer pliable frictional cylinder which is rotatably supported on the shaft mounted to the pivot arm in a vise-like arrangement, whereby the frictional cylinder can be squeezed to cause the outer diameter thereof to be adjusted to the proper frictional engagement with the ribbon or tape.
