An electronic fast-starting system for a textile loom in which an asynchronous driving motor, whose phase windings are triangularly connected, is mechanically connected to the main crank shaft of the loom and is controlled by an inverter/controller receiving not only the set speed value but also the outlet signal of a speed detector situated on the main crank shaft.

Electronic fast-starting system, particularly suitable for an air loom

A system for maintaining a constant terry height in forming a terry cloth despite loom stoppage, e.g., to correct yarn breakage. The system includes a proximity sensor which is positioned at a predetermined distance from a floating roller, and on the same side of the floating roller as a loading spring. The proximity sensor causes stoppage of an electric motor of the feed beam for the terry warp yarns which were previously driven in a forward direction by the electric control center. Upon sensing movement of the floating roller by a predetermined distance, the electrical control sensor causes motion inversion of the electric motor to reverse the movement of the feed beam for the terry warp yarns.
