Class 120(2) The pressure rollers in a gill spinning or roving frame are guided along a straight line passing through the axis of the delivery roller with which they are pressed into contact by a spring connected at one end to a pivoted rod upon which is slidably mounted a half-bearing co-operating with the pressure roller shaft. The pressure rollers 2 are mounted in pairs upon a shaft 3 and co-operate with the delivery roller 1. the ends of the shaft 3 engaging a slotted guide 4 directed towards the axis of the delivery roller. A rod 8 is pivotally connected to a shaft 6 and has slidably mounted thereon a half-bearing 7. A tension spring 10 is connected at one end to the rod 8 and at the other end to a lever 12 by an adjustable screw 11. The lever 12 is pivoted at 22 to a bracket 21 and by depressing the lever 12 the tension in the spring 10 may be increased to any desired value at which position the lever may be held fixed by the co-operation of a locking screw 13 with a slot 14 provided in an extension of the bracket 21. The hole in the lever 12 for the screw 13 is slotted to allow for the arcuate movement of the lever whilst the screw 13 moves in a straight line. The sliver 17, after leaving the gill bars 16 and passing the nip between the rollers, is carried over a guide 18 and through a yarn die 19.
