Abstract
A weft processing apparatus includes a weft releasing device for releasing or detaching a leading end of a weft from the peripheral surface of a weft cheese, a fluid jetting device for moving the released weft leading end to a weft introducing port of a weft length-measuring and reserving apparatus, and a guide device for guiding the weft leading end and the jetted fluid stream. The weft releasing device is in the form of a blow nozzle device or a suction pipe. In the former case, the blow nozzle device serves also as the fluid jetting device. The suction pipe has an intake port provided with a holding member such as a net or brush for temporarily holding the weft in a congregated state.
