Class 120(3) The sliver output of textile processing machines is delivered into rectangular cans subdivided into rectangular compartments which are filled by relative longitudinal traversing motion between a coiler-head and the can. Each sliver coil may have a diameter equal to the width of a compartment. The can width may correspond with the width of a draw-frame feeding sliver thereto and the can may be proportioned and/or subdivided to suit the dimensions of the succeeding machine. Thus, the width of each compartment in a can used at a carding engine is related to the gauge of a draw-frame i.e. for 18 inch or 20 inch gauge draw-frame cans with three or four compartments each 6 inches or 5 inches wide could be used at the card and two such cans fed to one head of the frame, placed one behind the other, at the finished draw-frame, or for direct sliver-to-yarn spinning frames, such as described in Specification 723,470, a can may have three or four compartments each corresponding in width to the spindle gauge, or, for feeding combers with 20 inch heads, a can may comprise four 5 inch wide compartments each of which could be divided to form eight compartments in the can. In preparing fibre for combing, eight card slivers are doubled, with draft less than 8, at each delivery of the first draw-frame to produce coarse sliver which is fed into a four-compartment can and three such cans are creeled at a second draw-frame, the twelve slivers contained in such cans being doubled, at a draft of 12, to produce coarse sliver which is coiled into an eight compartment can and used to feed one head of a comber, modified for sliver feed, or made into a lap to feed a conventional comber. In the apparatus shown, sliver 12 is delivered from a four-head draw-frame into cans 11, each divided into compartments 112, 113, 114, 115, by four coilers 10 each comprising a plate 101 driven from a shaft 103 by spiral gears 104 and 105 to rotate in a fixed plate 102 and carrying a tube 106 by which sliver is coiled within a compartment. Each can is mounted on a tray 13 on a platform 131 comprising shoes 15 which slide upon bars 16 between limit stops 17 to permit movement of the platform relative to a carriage 14 (in the direction of the arrow A) equal to the distance between centre lines of adjacent compartments. The carriage 14 is supported by brackets 18 slidable on bars 19 between limit stops 21 and a nut 22 co-operates with a driven right- and left-hand threaded screw 23 to effect traversing motion of the carriage, with automatic reversal at the end of each stroke, through a distance sufficient to permit sliver coils to be deposited throughout the length of the compartments. When the compartments 112, 114 are full (as determined by a measuring mechanism 24), the platform 131 is moved into position over the compartments 113, 115 (without interrupting the sliver delivery or the carriage traverse) by means of solenoids 25 and 125 electrically connected to and energized sequentially by the mechanism 24. When solenoid' 25 is energized, a bar 26 is retracted, withdrawing a peg 37 from a slot 36 in a bar 34 and causing a lever 27, 28, to pivot until the arm 28 abuts on arm 30 (and extends a spring 32) and thereby pushes a peg 35 to force a bar 34 and the platform 131 to the left; during the latter movement, a peg 135 engages an arm 130, tensioning the spring 132 and moving members 127-132, associated with the solenoid 125, to the position shown in respect of members 27-32 (in preparation for movement of the platform 131 to the right during subsequent filling of fresh cans) and finally, a peg 137 enters a slot 136 to lock the bar 34.
