PURPOSE:To make it possible to correspond freely with die dimensions to be variously altered only by one alignment mechanism, by setting a rotary angle of a cam with a digitally set actuator, and by advancing or retreating two sets of alignment detents perpendicular to each other to put a die therebetween or to release it. CONSTITUTION:When a pulley 12 is rotated through another pulley 10 and a belt 14 by driving an actuator 8, a cam 16 is rotated and therefore alignment detents 18, 18a are advanced or retreated to put a die 20 therebetween or to release it. At this time, the dimensions and shapes of the cam, etc., are selected so that there exists a straight relation between rotary angles of the stepping motor for the actuator 8 and the detent intervals between the alignment detents 18, 18a. The intervals between the alignment detents 18, 18a and 19, 19a are set by feeding numerical values to the actuators 8, 9 independently. By setting longitudinal and transverse sizes of a die 20 into a controller 24 with a key board, the longitudinal and transverse detent intervals putting the die 20 therebetween can be controlled to become the die dimensions. |
