US 5,529,257 A · Strip accumulator

Abstract

A strip accumulator for forming a length of strip material into a storage coil composed of an inner set of convolutions and an outer set of convolutions and an outer set of convolutions interconnected by a free reverse bend which will move freely in opposite paths, the strip being supported on one edge on a horizontally disposed supporting surface with the inner set of convolutions built up around an inner arbor, the outer set of convolutions being formed on a moving supporting surface being driven in timed relation to the feeding speed of the strip being accumulated providing a free-formed outer set of convolutions to the elimination of an outer roll basket and roll adjusting mechanism heretofore employed to form and support the outer set of convolutions in the storage coil.

Dependent claims

A strip accumulator for forming a length of strip into a storage coil composed of an inner set of convolutions and an interconnected outer set of convolutions, including:

a horizontally disposed support for receiving an edge of a length of strip travelling along a first path, said support including an annular outer support and a coaxially disposed inner support mounted to rotate independently of the annular outer support;
feed means for delivering strip on edge onto said support at a predetermined speed;
an inner arbor positioned centrally of said support and including an annular array of parallel spaced apart rollers adapted to rotate about axes inclined slightly from a vertical axis;
and
driven means forming a part of said support to impart rotational movement to said strip at a predetermined rate of rotation whereby the strip is caused to travel a helical path about said inner arbor to exit said arbor along a second path at a level above the first path.
