More Information
Summary:A pinch roll unit (24,26) for either propelling or retarding a product moving along the pass line (PL) of a rolling mill comprises a pair of levers (30a,30b) mounted for rotation about parallel first axes (A1). Roll shafts (32a,32b) are carried by the levers with each roll shaft being journalled for rotation about a second axis (A2) parallel to the first axis of its respective lever. Pinch rolls (34) are carried by the roll shafts and are positioned to define a gap therebetween for receiving the product. An electrically powered first motor (36) operates via a linkage to rotate the levers about the first axes and to move the pinch rolls between open positions spaced from the product, and closed positions contacting and gripping the product therebetween. An electrically powered second motor (56) rotatably drives the pinch rolls.
