Title: Striker mechanism for shuttle - for weft insertion in a loom
IPC: D03D49/38
Filed: 1970-12-29
Abstract: Striker mechanism for a shuttle loom, has a conical roller which imparts an acceleration to the shuttle over the whole width of the reed, depending on the initial speed of the shuttle, so that its inertia carries it through the shed as a result of the terminal velocity of the accelerated motion. A rotational velocity > half that of the main shaft of the loom, i.e. the usual velocity of the weft cam and equal to an integral multiple of this half speed is given to the weft pulley which is periodically inactive when the running of the conical roll over the nose of the weft cam does not coincide with the introduction of the weft yarn, so that the maximum speed given to the weft roll is increased and the time required for its movement over the cam nose is reduced along an equal arc of the nose profile.
