Abstract

Abstract A cloth beam rests on a pair of driven spaced-parallel rollers. One or more uprights define a sinuous cam to which the cloth beam is coupled to execute reciprocating endwise motion as the axis of the cloth beam is moved away from the plane of the axes of the rollers with growth in the diameter of the roll of cloth wound up on the beam.
