Abstract
A sled which is mounted between an uncoiler and a multiple-head or arbor type slitter and which carries a pair of pinch rolls and a peeler. The sled is adapted for longitudinal movement between the slitter and the uncoiler to allow indexing of the slitter arbors and feeding of the coil initially into the slitter.
Claims4
In combination, a slitter having multiple pairs of arbors, said pairs of arbors being generally radially oriented and rotatable in a general horizontal plane whereby one selected pair of arbors can be positioned across a material pass line and a second pair of arbors can be pretooled for a subsequent slitting operation, an uncoiler having arbor means for carrying a coil of sheet material, and a sled positioned between said slitter and said uncoiler, said sled carrying a pair of pinch rolls and a peeler, means for mounting said sled for shiftable movement along said material pass line between a position adjacent the slitter and an extended position spaced sufficiently from the slitter to allow rotation of said second pair of arbors across the material pass line, and means mounting said peeler for movement between a lowered inoperative position and an upper operative position for directing the leading edge of said sheet material from the uncoiler towards said slitter when the sled is in its said extended position.
