Abstract:
A system comprising(a) a first drawing frame having a sliver output where sliver from the first drawing frame is deposited in coiler cans;(b) a second drawing frame having a sliver input where sliver is supplied to said second drawing frame from sliver-filled coiler cans; and(c) a conveyor apparatus for supplying, in a closed circuit, sliver-filled coiler cans from the output of said first drawing frame to the input of said second drawing frame and for supplying empty coiler cans from the input of said second drawing frame to the output of said first drawing frame; said conveyor apparatus including(1) a first storage device for supporting a plurality of sliver-filled coiler cans; said first storage device being formed of a first conveyor track extending between said output of said first drawing frame and said input of said second drawing frame; said first conveyor track having an input end and an output end;(2) a second storage device for supporting a plurality of empty coiler cans; said second storage device being formed of a second conveyor track extending between said input of said second drawing frame and said output of said first drawing frame; said second conveyor track having an input end and an output end; said output end of said second conveyor track joining said input end of said first conveyor track and said output end of said first conveyor track joining said input end of said second conveyor track; said first and second conveyor tracks being mutually non-intersecting and non-overlapping;(3) conveying means for solely unidirectionally advancing the sliver-filled coiler cans and the empty coiler cans in a continuous, non-intersecting and non-overlapping endless path; said conveying means including(i) a first conveying device for moving the sliver-filled coiler cans on and along said first conveyor track; and(ii) a second conveying device for moving the empty coiler cans on and along said second conveyor track.
