ABSTRACT:
An apparatus for guiding a weft or filling thread in the shed of a weaving machine, the weft thread being driven by a flowing fluid medium, comprises two lamellae combs which can dip into and out of the warp threads. The lamellae or equivalent plate-like guide elements of the lamellae combs each possess a throughpass opening for guiding the weft thread and a thread exit or outlet opening. When the lamellae are in a position completely immersed in the shed they are interleaved or shoved into one another and form a guide channel for the weft threads, this guide channel being coherent or continuous in the weft insertion direction. Hence, the thread exit or outlet openings are sealed, so that the guide channel also is continuously closed in radial direction. The closed guide channel renders possible, on the one hand, a controlled flight of the weft thread, a reduced energy consumption and driving of the weft thread both by a blowing action and also by a suction action and, on the other hand, can be particularly advantageously employed at a multiple longitudinal traversing shed loom containing a weaving rotor.
