A rotatable element (,) is configured with a helical, endless thread guide passage (,) which is used to twist at least two threads (,), particularly in a weaving machine's selvage forming device (,). The threads (,) are guided in the passage (,) and displaced axially and mutually crossed by rotating the rotatable element.

A gripper weaving machine having at least one rapier (1) which carries a gripper (3) and is driven by a drive wheel (9) and which is guided outside a shed by guide elements (13, 15), where the guide elements are part of guidance devices and are arranged to rotate the rapier (1) about its longitudinal axis (28).

A method and apparatus for removing waste selvages (11) formed when weaving fabric on a loom includes a pair of selvage removal rollers (19, 23) fitted with friction coverings and driven against one another to form a gripping nip for engaging and drawing the waste selvage away from the woven fabric, whereby the waste selvage is first fed to the peripheral surface of the first one of the pair of removal rollers (19) over a wrapping angle larger than 150.degree. and preferably larger than 180.degree., before reaching the clamping nip between the rollers (19,23). Alternate embodiments of the invention are described.

A device for forming a shed in weaving machines includes a harness and coupling elements for coupling the harness to a drive mechanism. The height of the harnesses is made adjustable by mounting respective coupling elements on setting screws integrated into the side beams of the harness elements and movable relative to the side beams for enabling individual height adjustment of each harness element relative to its coupling element. Because the height adjustment is done on the harness itself, the height adjustment can be done when the harness is inside as well as outside the weaving machine. The setting screws extend through the side beams to the coupling elements, which are situated below the harness, adjustment being effected by turning the screws from the top of the side beams to move of the harness up and down relative to the ends of the setting screws and coupling elements coupled thereto at the bottom of the side beams.

A weaving method makes use of a set of weaving frames arranged such that, in each weaving cycle, some of the weaving frames are held in an identical extreme position, while all remaining weaving frames are moved in order to provide different tensions for the top and bottom warp threads at the moment of beating up. The shed is formed so that at the moment of crossing, as the weaving frames change position, the length of the course followed by the crossing warp threads is equal or almost equal to the length of the course followed by the warp threads held in the extreme position.

A pneumatic thread holder for a selvedge device on weaving machines includes a blower nozzle, a support for the weft thread located underneath the nozzle, and an opening for the weft thread in line with the blower nozzle. The opening is enlarged transverse to the blowing direction of the blower nozzle in order to prevent air current reflections or deviations from occurring when the tucking needle passes beneath the opening, thus ensuring that the end of the weft thread remains held in a correct position by the pneumatic holder.
