ABSTRACT:
A mechanism for driving a beat-up reed and a selvedged forming needle in timed relation in a needle loom is disclosed. The mechanism comprises a pair of parallel spaced first and second rock shafts to which a reed carrier arm and a selvedge forming needle carrier arm are respectively attached. Only one of the first and second rock shafts is driven by a drive means to oscillate through a predetermined angle. There is a linkage connecting the first and second rock shafts for transmitting such oscillatory motion of one of the first and second rock shafts to the other. The linkage includes a pair of levers angularly adjustably connected to the first and second rock shafts, respectively, and a link connected at opposite ends to respective free ends of the levers.
