Method and apparatus for pneumatic insertion of a weft thread in the shuttle of a multi-feed weaving loom

An apparatus for pneumatic insertion of a weft thread into the shuttle of a multifeed weaving loom having an injector (23) exposed to compressed air to which the weft thread (24, 24a) can be delivered from a thread measurement and supplying apparatus (56, 56a, 57) and which is disposed near the movement path of the shuttles (9) of the multi-feed weaving loom in such a manner that the weft thread can be inserted into a weft thread magazine (29) of one shuttle (9) at a time traveling past the injector,

• characterized in that
• the injector (23) is movably supported along a portion of the movement path of the respective shuttle (9);
• a driver mechanism (30, 40) is coupled to the injector, movement of the injector being synchronized with the movement of the shuttles (9) to provide for coupled movement of the shuttle (9) with the injector (23) at least during the insertion of the weft thread (24) into the weft thread magazine (29) of the respective shuttle (9),
• said driver mechanism controlling movement of the injector beginning at a start position (I), then extending over a predetermined distance (I-II) to a terminal position (II);
• and means (34-38) for effecting said coupled movement of the injector (23) at a predetermined lower speed with respect to the speed of the shuttle (9).
