Abstract:
1. An apparatus for winding up a strip, the apparatus comprising: a pair of rotor disks spaced along and rotatable about an axis; a beam extending axially between and fixing the disks together for joint synchronous rotation; two angularly offset pairs of axially spaced holders axially shiftable along the beam; a respective spreadable head on each of the holders, the head of one of the holders being axially aligned with the head of the other of the holders of the respective pair; means for rotating the disks, beam, and holders synchronously about the axis with the pairs of heads traveling angularly between a winding position and a transfer position offset angularly from the winding position; a pair of drive shafts extending along the axis inside the beam; respective means for transmitting torque from each of the shafts to a respective one of the heads of each of the pairs; respective drive means connected to the shafts for rotating the shafts and thereby rotating the respective winding heads and winding up a strip engaged with the winding heads; and respective actuators for axially shifting each of the holders on the beams independently of the other holders between a closely juxtaposed position when in the winding position for holding and winding a strip and a widely juxtaposed position when in the transfer position for removal of a wound strip.
