APPARATUS FOR DIRECTING WEFT THREAD INTO A GROOVE OF A ROTARY REED OF WEAVING LOOMS

A traveling-wave shedding loom havng a plurality of weft inserting means adapted to follow an endless path and each carrying each a pirn with a necessary weft thread length to be inserted into said wave-travelling shed, a plurality of spooling heads designed to follow, within a certain section, the same endless path as said weft inserting means and to pay off said necessary weft thread length to the respective weft inserting means within said certain section of said endless path, said weft inserting means leaving then said respective spooling head and proceeding on its course toward the wave-traveling shed along a straight path, and a rotary reed comprising a plurality of recessed discs disposed face-to-face on a common shaft in such relative angular position that said recesses together form a helical groove to receive the weft threads for conveying it to a beat-up position adjacent the fell of the woven fabric being produced, the axis of said rotary reed being parallel to said straight path of said weft inserting means. The loom includes a weft thread deflecting element disposed between said rotary reed and the path of said spooling heads and adapted to reciprocate between two extreme positions while shunting said weft thread in each of said extreme positions and between them so as to correct an angle of the weft thread entering and already received by said helical groove in said rotary reed to correspond to the lead angle of said groove. The weft thread, in one of said extreme positions of said weft thread deflecting element, is beaten up to the fell of woven fabric by the first or foremost disc of said rotary reed.
