CONTROL APPARATUS FOR WAVE SHED FORMING MEANS

摘要

Apparatus for controlling the movement of shaft rods in progressive shed looms, that is, weaving looms which perform the simultaneous weaving of weft threads, the shaft rods performing a wave-like harmoniously repeated continuous shedding movement by individual sections. Counter-movement of at least two shaft rods of one section moving in forced opposite directions is provided by one lever means which is phase shifted with respect to the other sections and reciprocates in accordance with the phase shift. The ratio of arms of the lever means is changeable, the point of tipping of the lever means being adjustable. To close the sheds, the symmetrically dead center area of the lifting means of the shaft rods is symmetrically limited, and thereafter the said shaft rods are displaced into alignment.
