Abstract (en)

Pneumatic weft tensioning safety device for air looms, of the type in which a weft yarn (F) is launched by air jets into a launching channel (5) formed in the loom reed (3) and, at the outlet of the shed, the free end of said yarn is deviated towards the inlet mouth of a lateral weft tensioning channel (11) by an air jet (12) substantially transversal to the direction of said launching channel (5). The lateral weft tensioning channel (11) has an arc-shaped path and leads into a channel extension (6) of said launching channel (5). Means (13) to detect the presence of the weft are positioned in said channel extension (6), downstream of the outlet mouth of said lateral channel (11). <IMAGE>
