ABSTRACT:
An accumulating apparatus for storing a variable length of strip material in which said strip is in the form of two adjacent spiral coils mounted on a common horizontal axis. The rolling coils of the accumulator are identical in size but are wound in opposite directions with their inner ends connected to each other by a bridging portion of the strip material which rotates in opposite directions in dependence upon the relative preponderance of the rate of accumulation and/or withdrawal of the strip material into and from the apparatus. Each of the spiral coils is supported on the interior thereof by a system of angularly spaced rollers capable of assuming circular orbits of varying diameters corresponding to the inner diameters of said coils, to control the sag of successive lengths of the strip between the rollers, which facilitates the interface creeping between the successive turns of the coils. This effect may be enhanced by applying tractive forces to the supporting rollers, if found desirable.
