  • Patent number: 3968817
    Abstract: Method of and apparatus for continuous progressive beating up of weft in travelling-wave shedding looms with simultaneous picking of weft threads into the warp in which the weft in the shed is affected by a beating up force progressing in the weaving direction. The weft is first affected by a beating up force which is the resultant of a force acting in the direction of the weaving plane and another force acting in the direction towards the weaving plane, and then is affected by a beating up force acting in the direction of the weaving plane, while the beating up force continuously progresses in accordance with the travelling shed weaves along the whole warp width.

  • Patent number: 3933183
    Abstract: Method of and apparatus for eliminating a chain formation of wefts not transferred into the beat-up position of a travelling-wave shedding loom with weft inserters and a rotary reed comprising discs with cutouts for engaging weft and displacing it to the fabric fell. An interwoven but not transferred weft is introduced into the cutouts of the discs of the rotary reed; such cutouts corresponding to the next weft inserter, in lieu of the weft from said next weft inserter. The weft from the next weft inserter is introduced into the cutouts of the discs of the rotary reed, such cutouts corresponding to the next following weft inserter. Due to this phase-shift corresponding to the distance between two weft inserters following after each other, all the other wefts are successively directed into the cutouts of the discs of the rotary reed until the loom stops.
