ABSTRACT:
This device designed for weaving machines enabling a weft selection, comprises for each prefeed and measurement device (1), an electric drive motor (8) having a controlled angular position, such as a "step" motor. The angular position of the main shaft (14) of the weaving machine, detected by means of a coder wheel (24), is converted into pulses (D) which are supplied by a "switching system" (15) which may be switched from the weft selection control (16) to the electronic power circuit (17) associated with the motor (8) of the prefeed device (1) selected. It is therefore possible to drive the shaft (5) of the selected prefeed device through a predetermined number of rotations synchronously with the rotation of the main shaft (14) of the weaving machine.
