ABSTRACT:
A feeder mechanism for feeding a sheet of metal to be blanked in a zigzag fashion in cooperation with a sheet of metal feeder mechanism of a press. A reversible D.C. motor is employed for reciprocating the sheet of metal in a direction at right angles to the sheet of metal feed direction of the press. The forward and reverse rotation and its cycle of the D.C. motor are controlled by a controller in synchronism with the feeding speed of the sheet of metal. The rotational motion of the D.C. motor is translated into a linear reciprocating motion of a die set by a rack and pinion mechanism. The rack is connected to the die set and is reciprocated in a direction at right angles to the sheet of metal feed direction of the press.
