ABSTRACT:
To introduce weft threads (31) or picks of finite length into a storage shuttle (1), the shuttle is formed with a longitudinal recess (4) which is divided into two chambers (11, 12) by a longitudinally extending separating wall (8) leaving a gap (10) between the bottom edge of the separating wall and the bottom wall (6) of the recess (4). Bristles or hairs extend preferably from both sides of the separating wall (8) towards the opposite wall (5, 5') defining the recess (4). A weft thread injector (2) is positioned to engage into the first chamber (11) to pneumatically inject the weft thread into the first chamber, to be retained in undulating or zig-zag pattern in the first chamber. Air is deflected by 180.degree. around the gap (10) and exhausted at an exhaust opening (14) leading from the second chamber (12). Preferably, a thread brake (19) is located at the trailing end of the shuttle, in the direction of relative movement between the shuttle and the injector to clamp the end of the injected weft thread.
