Kind Code:
A
Abstract:
Continuous unwinding apparatus for web material comprises a pair of opposed end stands, each of which carries a pair of roll-carrying arms mounted for independent rotation on a common axis, and a splicer assembly is mounted for adjusting movement with respect to the end stands to accommodate rolls of definite diameters. There is no center shaft between the end stands, but separate drives couple opposed pairs of arms and provide for driving each coupled pair in either direction in any desired speed. An outstanding characteristic of the apparatus is that the movements of each pair of arms between splicing and final unwinding positions are confined to two quadrants of rotation.
