  • Patent number: 4614209
    Abstract: In a weaving rotor of a multiple longitudinal traversing shed weaving machine a beat-up lamella of a first beating-up comb lies in a plane extending substantially perpendicular to the rotational axis of the rotor and centrally between two beat-up lamellae of a next following beating-up comb. The greater division or pitch of these beat-up lamellae permits a faultless insertion of the weft threads into the lanes or intermediate spaces of the shed-forming combs. Nevertheless, when considered with regard to two subsequent beat-up operations, each weft thread is practically beat-up as if each beating-up comb were equipped with the full number of lamellae.

  • Patent number: 4492255
    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.
