Abstract
Continuous strip accumulator includes a convolution transfer annulus providing for controlled expansion and contraction of the stored convolutions between inner and outer sections within the accumulator. During mill match operation of the accumulator, the convolution transfer annulus is retained against movement but still provides support for the strip material as it moves from the inner section to the outer section. A differential drive between the entry and exit pinch rolls provides for mechanical synchronous operation of the entry and exit pinch rolls during the mill match mode. During the welding mode, when it is desired to replenish the supply of strip material, movement of the incoming strip is stopped and the convolution transfer annulus is driven by the differential drive in a direction causing positive transfer of the convolutions from the outer section to the inner section in mechanical synchronism with the exit pinch rolls to provide a continuous uninterrupted supply of strip material to the mill. After the supply has been replenished, the entry pinch rolls are accelerated to fill speed during which the differential drive first causes the convolution transfer annulus to …
