ABSTRACT:
In order to monitor the correct receiving of an inserted weft yarn by a gripper in a receiving unit of a shuttleless weaving loom a detector is provided which is stationary mounted on the receiving side in an interspace between said gripper and a slay bar or reed of said weaving loom. Said detector comprises a plate-member projecting into said interspace or gap and having an inclined flank which is contacted by the weft yarn on his path between the inserting position and the beaten-up position. The passing of the weft yarn over this flank is detected by measuring potential variations in the detector during a defined phase of the machine cycle.
