Device for making a preparatory incision longitudinally of an animal extremity part with first and second bones articulated by a joint.

摘要

A device (1, 9; 109) for making a preparatory incision longitudinally of an animal extremity part (L) having a first bone and a second bone articulated by a joint, and surrounded by meat. The device (1, 9; 109) includes an elongate linear guide member (15; 115), a cutting unit (21; 121) associated with the elongate linear guide member for translating movement lengthwise thereof. The cutting unit (21; 121) includes a cutting knife (51; 151A, 151B) mounted for movement between a first position and a second position in a first plane. A conveyor (5, 7; 201, 207A, B) is arranged for transporting animal extremity parts (L) through a path coincident with the cutting unit (21; 121). The device (1, 9; 109) further includes a primary drive mechanism (19, 39; 119, 139) for moving the cutting unit (21; 121) lengthwise of the elongate linear guide member (15; 115). The device (1, 9; 109) also includes a secondary drive mechanism (23, 27; 123, 127) for moving the cutting knife (51; 151A, 151B) between the first position for receiving an animal extremity part (L) transported by the conveyor (5, 7; 201, 207A, B) in the cutting unit (21; 121), and the second position for performing the preparatory incision longitudinally of the animal extremity part received in the cutting unit.
