A loom of dual rapier arm type comprising:
- a giver arm attached to the loom on the side where the weft fiber is fed to the loom;
- a taker arm attached to the loom on the side opposite of the weft fiber feeding system;
- a transfer device connected to the giver arm device which traverses the shed of the loom;
- a weft fiber feeding system attached to the loom which feeds weft fiber to the transfer device on the giver arm;
- a retaining disc which is attached to the transfer device;
- wherein the transfer device is fitted to the giver arm in its default position at the weft fiber feeding side of the loom so that a weft fiber is fed into the retaining disc;
- wherein the retaining disc holds a weft fiber in a fixed orientation as it travels through the shed;
- one set of projecting pins, the taker projecting pins, attached to the taker arm side of the transfer device;
- one or more capture arms attached to the taker arm;
- wherein the capture arms capture the taker projecting pins when the giver arm meets the taker arm in the middle of the shed of the loom and the transfer device can slide longitudinally along the frame of the giver arm such that it travels with the taker arm after capture, drawing the retainer disc and weft fiber through the width of the loom's shed;
- a spring loaded deflection plate attached to the giver arm;
- one or more return arms connected to the deflection plate which are operationally associated with the deflection plate such that when the deflection plate is down with the spring compressed, the return arms are down and when the spring forces the deflection plate up, the return arms are raised into their return position;
- wherein the default position of the return arms and deflection plate is the down position when the transfer device is on the giver arm at the side of insertion and the return arms and deflection plate move to the up position when the transfer device moves from the giver arm to the taker arm after the rapier arms meet in the middle of the loom's shed;
- a pinion connected to the hub of at least one of the return arms;
- a rack engages the pinion and the operation of the pinion on the rack translates the rotation of the return arms to a linear movement of the rack such that the rack moves along the longitudinal direction of giver arm;
- an actuator shaft connected to the rack which moves linearly along the longitudinal direction of the giver arm such that the actuator shaft extends beyond the end of the giver arm when the return arms move to the up position;
- an actuator lever attached to the taker arm such that the extended actuator shaft of the giver arm can move the actuator lever when the giver arm and taker arm meet;
- wherein the actuator lever is operationally associated with the capture arms of the taker arm such that when the actuator lever is moved by the extended actuator shaft of the giver arm, the capture arms move and release the taker projecting pins on the transfer device;
- a set of projecting pins, the receiver projecting pins, connected to the giver side of the transfer device such that when the giver arm and taker arm meet, the return arms are in a position to capture the receiver projecting pins and return the transfer device to the giver arm.
