  • Patent number: 5253681
    Abstract: The reed of an air weaving loom is divided into spaced sections for forming a fabric gap. The warp threads are guided through the reed sections, but are absent in a zone of the fabric gap. The weft threads that would bridge the fabric gap are cut in the gap and formed into a selvage. The gap, is formed where the reed sections are spaced from each other to form a breach. A reed filler member is mounted in a stationary position in the reed breach, so that the filler member aligns with the reed sections when the reed is in the rear position. Only the reed sections perform the beat-up motion.

  • Patent number: 4540028
    Abstract: The invention relates to a shuttleless weaving machine with a reciprocating filling yarn inserting gripping member or rapier and a reciprocating pulling out gripping member or rapier forming a gripper device (1). In order to shorten the waste in filling yarn and to present a filling yarn (S1) selected by a yarn feed system in a specific position, the feed system forms a fanning-out arrangement in such a manner that each of the yarn guides (3), when in its operational position (3'), always assumes the same position. A holding device (8) for the cut-off end of the selected filling yarn (S1) is made to sufficiently yield the held yarn end, whereby the yarn end held by the holding device (8) can be retracted a distance by a controlled yarn retraction system (4, 12). The yarn retraction system (4, 12) is located between the path of the gripper device (1) and the yarn guides (3) of the feed system.
