714,195. Preparing fibres for spinning. FRASER & SONS, Ltd., D. Dec. 31, 1952 IMarch 1, 1952], No. 5448/52. Class 120(1) Apparatus for producing sliver rolls of bast or leaf fibres consists in the combination of a hackling machine or spreader 1 of the type comprising slow-moving pins, fast-moving pins and a pair of drawing rollers, and a roll former 4 including driving rollers 5, the tractive force applied to the sliver by the driving rollers and the sliver roll pressing thereon being alone used to draw the sliver band through a condensing conductor 8 mounted between the drawing rollers 2 and the roll former; the delivery rollers which are usually used to draw the sliver through the conductor are dispensed with, whereby oil-in-water emulsion sprayed through a nozzle 20 on to the sliver passing through conductor 8 is not, as previously, largely squeezed out at the nip of the delivery rollers. The peripheral speed of rollers 5 exceeds that of rollers 2. Conductor 8, which is removable, is located in position by notched brackets 10 resting on a horizontal bar 11 on the hackling machine and a clip 17 engaging a plate 16 on the roll former. An angularly adjustable plate 14 projects inwardly through each side wall 13 of the conductor to control the width of the sliver band. The end portion of the conductor adjacent rollers 2 is hinged at 18 so as to be movable downwards in the event of lapping of rollers 2, this portion of the conductor being maintained in operative position by spring catches 19.
