Claims7
An apparatus for unwinding a substantially round coil of strip material, said apparatus comprising:
- a frame including first and second opposingly positioned upstanding side members;
- a plurality of spacedly positioned rollers for engaging the periphery of said coil over a substantial arc to rotate and position said coil within said apparatus, each of said rollers having a first end portion securedly positioned to said first upstanding side member of said frame and a second end portion securedly positioned to said second upstanding side member of said frame;
- first and second opposingly positioned alignment members movably oriented within said apparatus substantially between said first and second upstanding side members for moving toward and away from each other to engage the sides of said coil and maintain alignment thereof;
- motion means including a pair of hydraulically actuated piston members, each of said piston members operatively connected to one of said alignment members for imparting motion thereto to provide said movement of said alignment members toward and away from each other;
- and
- drive means operatively joined to at least one of said spacedly positioned rollers for driving said roller to provide said rotation of said coil within said apparatus.
