ABSTRACT:
The invention is concerned with an electronic weft or filling thread monitoring device on a gripper shuttle weaving machine provided with means for moving the gripper shuttle, at the end of the shuttle insertion, back from a stop position to a yarn releasing position, and simultaneously tensioning the thread. The monitoring device comprises thread sensing means responsive to thread travel as well as to thread tensioning and provides machine stopping signals when neither continuous thread travel nor thread tensioning occurs in predetermined, machine-controlled monitoring intervals.
