Abstract

A device of compressed fluid for the feeding of material in strip to a press, with two flanges or elements of tighten, of control by fluid, destined to put them in positions of tightening of the band by alternations, a jack of fluid control to move in reciprocation one of said flanges, a valve that subordinates the arrival of air to said controls, and a shutter controlled by fluid coming from the valve to selectively interrupt the arrival of air to said jack command, comprising the improvement that constitute in combination, a selector of two positions placed between the valve and the obturator, and the disposition in the valve of two orifices of exit of fluid destined to open and to close following the movements of the press, corresponding the opening of one with the closing of the other, leading one of said holes to the flanges and to the shutter, and the other only to the shutter, and the selector to be selectively blocked being destined fluid is given to the obturator, which comes from one or the other of said orifices, depending on whether it occupies one or the other of its two positions.
