Abstract
A retention nozzle is provided at the catch side of the weaving machine for clamping or retaining the weft thread end during severance of the weft thread by means of a shear. A transfer nozzle is also provided at the catch side. When the weft thread lies over the transfer nozzle after being severed, the transfer nozzle is supplied with blower air and subsequently the supply of blower air to the retention nozzle is interrupted. In this manner the weft thread end is withdrawn from a catch channel of the retention nozzle and blown into a catch channel of the transfer nozzle. During this operation, the weft thread end is conducted through an eyelet of a selvedge-laying needle and thereby transferred to the latter. The retention nozzle permits severance of the weft thread by means of the shear even before the weft thread is in alignment with the eyelet of the selvedge-laying needle and the transfer nozzle.
