Abstract

1387536 Spinning yarn from sliver TOYODA JIDOSHOKKI SEISAKUSHO KK 19 Oct 1973 [19 Oct 1972] 48883/73 Headings DID and D1F In the supply of slivers to one or both sides of a spinning frame 1 from cans and the removal of empty cans therefrom, Figs. 2 and 3, immediately before the slivers in cans b in an inside row run out, a sufficient number of full cans a is moved automatically along a supply path 15 and these cans are stopped opposite their respective spinning stations. Thereafter, replacement of cans is effected automatically by piecing the leading ends of sliver in the full cans with the trailing ends of sliver remaining in cans b and then simultaneously moving cans in the same direction so as to push empty cans d onto path 14 for removal by a conveyor passing through a space 12 in the frame, move outside cans c (which at this stage are half-full of sliver) to an inside row, and move full cans a to an outside row. In a can circulating system, Fig. 1, for distribution and transportation of cans between drawing frames 4 and spinning frames 1, full cans a available on a conveyor 5 moving in the direction of arrow A are directed through leading means 9 onto paths 15 in the direction of arrow B as required by the frames, and empty cans d are returned along path 6.
