ABSTRACT:
The invention relates to weaving mechanisms and can be used to advantage in wave-type shedding looms. The mechanism includes a plurality of toothed discs mounted in a staggered fashion on a shaft and defining a helical surface having a portion of a varying radius diminishing axially in the direction of the advancing motion of the helical surface. Underlying the discs are support rollers with lugs defining a helical surface engaging the helical surface defined by the valleys of the discs and likewise having a portion of a varying radius, engaging the corresponding portion of the helical surface defined by the valleys. Such an embodiment simplifies the structure of the mechanism and obviates the need in a drive of the support rollers.
