Abstract

During the formation of a shed (2), the compensation of the warp-thread length in the event of a shed change and the setting of a different degree of tension of the shed branches (5, 6), the warp threads (1) are maintained under a tension which is near the introductory tension of the warp threads, specifically during the rotation of the main shaft through an angular sector of 250 DEG -340 DEG . At the moment when the weft thread is beaten up (4), a maximum tension, which is achieved during the rotation of the main shaft through an angular sector of 110 DEG -20 DEG , is imparted to the warp threads (1). There is an apparatus (11) which guarantees the varying degree of tension of the shed branches (5, 6) of the shed (2) and which possesses guide bars (12, 13) arranged so as to be capable of oscillating alternately in the vertical plane. There is a compensating element (14) which is mounted between the guide bars (12, 13), with the possibility of periodic action on the warp threads (1) in order to lift these between the guide bars (12, 13) at the moment when the weft thread is beaten up (4). This makes it possible to generate a brief maximum load on the warp threads only at the moment of beating up (4) of the weft thread, thereby affording the possibility of reducing the breaking frequency of the warp threads (1) during weaving and guaranteeing the production of denser fabrics.
