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.
The method of transiently storing a variable length of strip material on two adjacent spiral coils rotating on a common horizontal axis with the convolutions of the coils wound in opposite directions, comprising
An apparatus for storing a variable length of forwardly advancing strip material disposed in two adjacent spiral coils rotatable on a common horizontal axis with the convolutions thereof of substantially the same circumference but coursing in opposite directions, comprising
An apparatus for accumulating transiently a large quantity of rolling sheet material in the course of its travel in a horizontal plane from an intermittently operating source of supply to a continuously operating point of utilization, without twisting the sheet from its planar form, comprising
