<p>In a press for cutting and bending the leads of semiconductor packages, a series of cams on a common drive shaft operate both the feeding mechanism and the working presses to achieve high speed operation, up to 500 cycles per minute, through accurate timing and avoidance of delays inherent in fluid-operated presses. The path of movement of the packages through the apparatus is linear, and the axis of the camshaft is parallel to the path of movement. <IMAGE></p> |
