Title: Spool type valve controller for a pneumatic guiding system
Inventor: DUFOUR KENNETH STANLEY
IPC: B65H23/02
Filed: 1985-12-11
Abstract: The invention relates to a direct acting pneumatic control system for controlling a dual diaphragm, or double acting cylinder type automatic web guiding system. A control valve (15) is equipped with a palm or follower (18) which follows the web (10) and continually monitors the web position and activates a control valve spool (37) to modulate the "flow-exhaust" rates to bring the web 10 to the corrected position with no over-run or "hunting" for position. The palm (18) and rod follow the web when the web is moving away from the palm by means of differential pressure across the spool ends with the necessary porting (36c,37a) within the valve to accomplish the spool displacement. The valve has an inlet 40, outlets 50,51 and exhaust 52 and has different sized ends to fluid bias the valve and palm against the web. In the neutral position, the inlet and both outlets are connected.
