Abstract
In a selvage laying equipment a catcher nozzle (44) with a catcher channel (45) lying in axial prolongation of the nozzle and a threader nozzle (41) with a catcher channel (42) lying in axial prolongation of the nozzle are arranged in a carrier (54) with the axes of their air jets crossing one another, which enables a narrow construction of the device for threading the end (21a) of the weft yarn into the eye or hook of the selvage laying needle (11) and hence short ends (21a) to the weft yarn and narrow selvages, respectively. Bits of dirt such as fluff are reliably carried away from the gap (55) in the carrier (54) as well as from the catcher channels (42, 45) and the formation of an air dam is prevented.
