PETTINE CON CONFINATORE INCORPORATO, PER TELAIO DI TESSITURA SENZA NAVETTA A INSERZIONE DI TRAMA PNEUMATICA.

摘要

The loom reed (5) is formed of dents (9) defining a channel through which the weft is inserted and is drawn and guided by air jets produced by relay nozzles (3). To form the insertion channel, each dent (9) has a triangular projecting front part formed with a recess (6) opening towards the exterior at its top via an escape slit (7) slightly inclined relative to the longitudinal direction of the dent (9). The recess (6) has an offset (d) towards the front relative to the front straight edge of the dent (9). This feature is suitable for weaving threads with non-twisted, non-interlaced filaments, and enables beating-up to occur near the temples (8) after the weft thread has easily been extracted from the insertion channel via the slit (7).
