Abstract
Abstract A machine for uncoiling and straightening strip stock having a strip stock uncoiler means and an adjustable strip stock peeler means positioned adjacent the uncoiler means for stripping the leading edge of a coil of strip stock away from the body of the coil when the strip stock uncoiler means is actuated. A strip stock threading means is positioned adjacent the uncoiler means for receiving the leading edge of the strip stock coil from the peeler means and imparting to the strip stock a partial removal of the set that has been placed in the strip stock due to its winding into a coil. The threading means feeds the strip stock upwardly through an upper arcuate threading chute which then feeds the strip stock downwardly into a straightening means. A lower arcuate threading chute feeds the strip stock from the straightening means down and under the strip stock uncoiler means and thence to a strip stock processing machine without developing a set in the straightened strip stock.
