Abstract

1427078 Shedding motions ALMHULTS BRUKS AB 3 July 1973 [3 Oct 1972] 31597/ 73 Heading DIE A semi-closed shed shedding motion comprises oscillating levers 17, 18, which, through toggle linkages 9, 10 and 25, 24 alter the position of a pivoted lever 5, 4 controlling through a linkage 11 the heald shaft, the making and breaking of toggle linkages being controlled by a three arm lever 1, 2, 3 operated by a link 21 from a pattern reading mechanism, so that if a heald shaft is to be moved from top or bottom shed position, Figure 6, to the other, Figure 8, lever 1, 2, 3, is pivoted from the position of Figure 6 to that of Figure 5 such that as arms 17 and 18 pivot outwardly then inwardly again, toggle 9, 10 straightens and 25, 24 breaks, and if the heald shaft is to be moved to semi-closed position, lever 1, 2, 3, remains where it is and as the levers 17 and 17 move out then in, toggle 9, 10 partially straightens, Fig. 8 and moves the heald shaft close to the plane of the cloth. Levers 17, and 18 are oscillated once every pick by an eccentric 12.
