Title:
PROGRAM CONTROL APPARATUS FOR OPERATION ELEMENT OF FABRIC SURFACE MAKING MACHINE
Document Type and Number:
Japanese Patent JPS55152847
Kind Code:
A
Abstract:
Apparatus for programming a servo-element for controlling a component of a machine for making a textile web, for example for positioning a guide bar of a knitting machine, comprises a hydraulic servomotor (16) comprising a movable wall in the form of a piston (25) which is connected to the guide bar (11) and having at least one input device (18, 19, 20) having a movable wall also in the form of a piston (30, 31, 32). The total content of hydraulic fluid (33) in the two is constant. The input device (18, 19, 20) displaces hydraulic fluid (33) which is received by the servomotor (16) and moves the servomotor piston (25) and guide bar (11). During the return motion, the servomotor piston (25) pushes the hydraulic fluid (33) back into the input device (18, 19, 20) and thus moves the input device back to the starting position.
