PROBLEM TO BE SOLVED: To provide a gripper feeder which can realize a feeding frequency similar to that of a roller feeder.;SOLUTION: The invention relates to a device for intermittently feeding a band-shaped or wire-shaped semifinished product (22) to a press. The device comprises a pair of mobile grippers (4, 7) which moves forward and backward during feeding, a pair of clamping grippers (24, 27) which hold and fix the semifinished product (22) and do not move at a non-feed stage, and a control rocker (12) equipped with rocker drives (40, 42, 42a, 44 and 45) which are connected to one control end of the control rocker (12). The mobile grippers (4, 7) and the clamping grippers (24, 27) are coupled each other by the control end of the control rocker (12) with the rocker drives (40, 42, 42a, 44 and 45).;COPYRIGHT: (C)2008,JPO&INPIT
