ABSTRACT:
A method and device to store a moving strip of material in a continuous strip-feeding system adapted to variations of the feed-in speed in relation to rate of withdrawal, comprises forming a strip into a spiral coil having a constant number of turns and proceeding the strip in substantially the same angular direction with a spare space provided for convolutions to make variations of their mean diameter, and facilitating a change in the length of stored strip without direct forces applied perpendicular to a face of a single, or to a set of separated convolutions; and having the improvement in means to support and to run the strip along the convolutions involved, and comprises at the outer section a separate set of support rollers having at least two driven by a synchronized mechanical transmission from a torque generating unit, and also comprises at the inner section another set of rollers having at least two driven by another synchronized mechanical transmission.
