Abstract

1,239,979. Shuttleless ribbon looms. BREVITEX ETAB POUR L'EXPLOITATION DE BREVETS TEXTILES. 31 July, 1968 [25 Sept., 1967], No. 36561/68. Heading D1E. Weft inserter, Fig. 3. Two meshing gears 8, 9 have crank pins 8', 9' which engage a hole and a slot in a weft inserting needle 2; the resulting revolution of the crank pins in opposite directions causes the eye 2' of the needle to pass through the shed along a path 13a and to return along a path near the fell. Knitting selvedges, Fig. 10. As shown, a selvedge thread 31 is raised above the weft thread 38 by a guide eye 5 so that a loop of selvedge thread is drawn over the weft thread as the knitting needle 3 retracts; a loop of weft is formed around the loop of selvedge thread as the weft inserter 2 retracts, resulting in the selvedge thread being knitted through the looped ends of the picks. The weft inserting needle is arched at 2" to clear the eye 5. Alternatively, the loops of weft may be knitted together, with or without a selvedge thread. Smallware looms. A number of weaving units may be mounted in a row, with driving shafts extending along the row.
