ABSTRACT:
The binding of free weft thread ends at the exit of the weft thread insertion channel in an air weaving loom, into the fabric edge, is to be avoided. For this purpose it is necessary to straighten out the turbulent weft thread ends. The straightening is accomplished by a blowing nozzle that directs its air stream onto the free weft thread ends in a direction substantially defined by the fabric withdrawal. The auxiliary nozzle is arranged in an auxiliary reed section used for forming an auxiliary selvage. Such a blowing nozzle may be combined with a nozzle for stretching the weft thread end.
