Abstract
Two horizontally spaced adjacent stacks of vertically spaced support plates are vertically displaceable for aligning any of the plates with a fixed take-off station. A supply of strip material is provided on each plate and may be gripped between a fixed continuously driven roller and a displaceable roller. A controller may move any of the displaceable rollers toward or away from the respective fixed roller in order to pinch the strip material from the respective supply and feed it into the take-off guide aligned therewith.
Claims11
A feed apparatus for strip material, said apparatus comprising:
- a stack of support plates spaced apart one above another in an upright direction;
- means on each of said plates for holding a supply of strip material therein;
- means for displacing said stack in said upright direction through a plurality of positions each corresponding to alignment of a respective one of said plates with a fixed take-off guide;
- a fixed roller on each of said plates;
- a displaceable roller on each of said plates movable toward and away from the respective fixed roller;
- means on each of said plates for moving the respective displaceble roller toward the respective fixed roller for pinching the strip material from the respective supply;
- means for rotating one of said rollers on each plate and thereby pulling the material off the respective supply when same is pinched between the respective rollers;
- and
- means for displacing each of said plates out of said stack in a transverse direction transverse to the upright direction.

A feed apparatus for strip material, said apparatus comprising:
- a stack of support plates spaced apart in a direction;
- means on each of said plates for holding a supply of strip material thereon;
- means for displacing said stack in said direction through a plurality of positions each corresponding to alignment of a respective one of said plates with a fixed take-off guide;
- a fixed roller on each of said plates;
- a displaceable roller on each of said plates movable toward and away from the respective fixed roller;
- means on each of said plates for moving the respective displaceable roller toward the respective fixed roller for pinching the strip material from the respective supply;
- means for rotating one of said rollers on each plate and thereby pulling the material off the respective supply when same is pinched between the respective rollers;
- sensor means adjacent each supply for generating an output when the respective supply is exhausted;
- and
- control means connected to all of said sensor means, to said means for displacing said stack, and to all of said means for rotating for reverse-rotating a one of said rollers when the respective sensor means generates its output and for thereafter displacing another plate into alignment with said take-off guide.
