Abstract
On shuttleless looms on which wefts are inserted into sheds being carried on air or water jet flow, the leading end of the inserted weft is urged sideways to move forward across a detecting zone of a photoelectric detection mechanism fixed forward of the cross-fell line by a pair of forks on the lathe which assume a position forward of the cloth-fell line at the very moment of cloth-fell beating and is held in a limited space on the forward side of the detecting zone, thereby non-contact type photoelectric detection of success in weft insertion being practiced without faulty double detection to be caused by whipping of the weft end. For water jet looms, occurence of noises in the detection to be caused by wetting can be prevented by provision of pneumatic air blowing devices, and waterproof sheltering arrangements for the photoelectric system that permits the passage of light as well as the passage of the weft end.
