Abstract
A novel arrangement for the air circuit conduit lines of a pneumatically operated feeder for punch presses and the like. In order to insure that the stock gripping action of the feeder occurs before the initiation of the feed motion of the feed slide of the feeder a physically circuitous or roundabout path is provided for the air flowing between the control valve and the head end of the main feed cylinder. In this arrangement the main cylinder is located in the control circuit so as to be effectively disposed downstream of the stock grip cylinders when pressure air is directed to the main cylinder and so as to be effectively disposed upstream of said grip cylinders when pressure air is exhausted from said main cylinder. This arrangement will facilitate the establishment of the short but necessary time delay needed to enable the completion of the stock grip and release actions before movement of the feed slide commences.
