Abstract:
A combined material straightening and feed apparatus advance strip stock to a using station in synchronization with the operating cycles of the using station, the apparatus comprising:a) a first feed roll journaled for rotation about a first axis, b) a second feed roll journaled for rotation about a second axis parallel to the first axis and for swinging between first and second material-advancing positions, toward and away from the first feed roll, respectively, c) a first operator operably connected to move the second feed roll between said material-advancing positions, d) a first set of straightening rolls journaled for rotation about a first set of axes parallel to said first axis, e) a second set of straightening rolls journaled for rotation about a second set of axes parallel to the first set of axes and for swinging between first and second material-straightening positions, toward and away from the first set of straightening rollers, respectively, independently of the swinging of the second feed roll, f) a second operator operably connected to move the second set of straightening rolls between said material-straightening positions, and g) control apparatus connected to the operators for effecting synchronized movement of said second feed roll and said second set of straightening rolls between said first and second associated positions.
