Abstract

Weft thread distributor apparatus for a series shed weaving machine in which a weft thread is fed into a connection channel via a supply nozzle and is distributed within the connection channel to shoot-in tubes. In order to achieve a trouble-free cutting off of the inserted weft and rerouting of the new weft thread tip a cutting device is placed spatially between the shoot-in tube and the clamping device in order that a retraction force and a loop standing under said retraction force are already formed due to of the supply nozzle and the injector nozzle prior to the stopping of the weft thread in the clamping device. During the stopping in the clamping device the thread is pre-tensioned in the cutting device and can be cut without difficulty. The loop unwraps itself and a new weft thread tip is inserted into the shoot-in tube.
