Abstract
A pneumatic control arrangement for a high speed dual slide feeder for punch presses and the like; the feeder comprising two reciprocating feed slides which are respectively reciprocated by two main fluid motors and which respectively carry two gripper fluid motors. These four fluid motors are adapted to be sequentially controlled by only two control lines which arranged in a cross over type circuit and which have opposite pressure-exhaust conditions existing therein. This arrangement permits a substantial simplification in the valving and in the associated control lines over that normally required to produce the rapid successive alternate stock feed strokes of said feed slides; such thereby substantially reducing the cost of the feeder while increasing the reliability and durability thereof.
