Abstract: Fibre loosening device for a spinning unit of a spinning machine. The invention relates to a fibre loosening device for a spinning unit of a spinning machine. Before entering the fibre separating area, the sliver is longitudinally separated into fibre sections fed to a separating region, i.e., to helix-like arranged functional lines on the fibre separating roller, such feeding being non-simultaneous but sequential. The division into the fibre sections is initially carried out by means of protrusions defining grooves therebetween on a condenser, the axial distance between these grooves not being an integer multiple of the helix lead width of the functional lines on the fiber separating roller. The arrangement provides for reducing periodical irregularities of the fibres for the subsequent spinning process.

Abstract: A yarn guide is controlled by a pair of resiliently biased pneumatically operated pistons arranged cooperatively to alternately exert a directional movement on said yarn guide in opposite directions. One of the pistons engaging with the yarn guide to arrest its movement, in the absence of a pneumatic impulse to either piston.

Abstract: A plurality of knitting machines are controlled from a central control device and a common patterning memory. Each knitting machine is provided with its own needle and course counters in which the needle position is determined. The single control device provides separate clock signals to the counters of each machine so that they may be individually switched to the patterning memory. Simutlaneously, the control device provides means by which the output from the memory is switched to the electromagnet controlling needle operation in synchronism with the needle counter.
