    摘要： A yarn feeder is provided with a motorized, yarn-winding rotary drum (12) which is rotatable with respect to a motor-housing (16) and is adapted to have a plurality of yarn loops (Y) wound on itself, which are adapted to be unwound upon request from a downstream machine. A sensor comprises light-emitting means (42) and light-receving means (44), at least one of which is to be fixed to the rotary drum (12), which operatively define a light connection passing through a detection area (30c) of the rotary drum (12) which is adapted to be repeatedly engaged by the yarn during its rotational unwinding movement. The unwinding of yarn from the rotary drum is determined on the basis of the variation of light resulting from the yarn (Y) transiting on the detection area (30c).

    摘要： A motorized, yarn-winding rotary drum (12) rotatably supported with respect to a motor-housing (16) is adapted to have a plurality of yarn loops (Y) wound on itself, which are adapted to be unwound upon request from a downstream machine. A yarn-unwinding sensor counts the yarn loops unwinding from the rotary drum (12) and comprises light-emitting means (42) and light-receiving means (44), both integral with the motor-housing (16), one of which has an annular configuration operatively facing an annular surface (30a) of the rotary drum (12) from which the yarn is unwound. Light-guiding means (66) integral with the rotary drum (12) guide the light from the light-emitting means (42) to the light-receiving means (44) through a light passage (30c) defined on the annular surface (30a). The unwinding of yarn from the rotary drum (12) is determined on the basis of the light dimming resulting from the yarn transiting on the light passage (30c).

    摘要： The three-way connector comprises a first, a second and a third gates (CN_in, CN_out, CN_C) directly connected to one another. The first and second gate are pluggable onto respective spans (I1, I2) of a bus, and the third gate is connectable to a weft feeder (A1, A2, A3). The three-way connector further comprises a permanent memory (E2P) containing an identifying code for the associated weft feeder. A managing unit (SG) drives a serial bus (BUS) to which a plurality of weft feeders are connected. The serial bus comprises said cable spans (I1, I2), serially connected to one another through the first and second gates of the connectors, the weft feeders being connected to respective third gates of the connectors.
