摘要: A twist generator for a running fiber aggregate possesses two friction discs rotating in opposite directions and having end faces turned towards one another for the twisting of the fiber aggregate running between the friction discs. One friction disc is made flexible and is pressed by pressure rollers towards the end face of the other friction disc and consequently against the fiber aggregate. To allow defined conditions to be obtained as regards pressing force, there are two pressure rollers, of which one is arranged shortly before and the other shortly after the thread contact point of the friction discs in the direction of movement of the flexible friction disc. The two pressure rollers are mounted next to one another, but preferably offset in the direction of movement of the fiber aggregate, on a carrier which is pivotably fastened to a spring-loaded lever. The distribution of the pressing force to the two pressure rollers can be changed by adjusting the carrier relative to this lever.

摘要: The device is composed of a spindle (7) which is provided with a drive means (9 and 10), and of a member for providing a twist, in the form of a bell (1), which encloses the spindle and can be rotated about the extended spindle axis. The bell is mounted independently of the spindle and provided with a drive means (5 and 6), which is furnished with a built-in freewheel (4) to enable the bell to rotate more rapidly than its drive means.

摘要: The object of the process is to produce a yarn comprising a core of continuous filament and a sheath of staple fibers. The staple fibers are delivered to a suction surface comprising a perforated collecting surface exposed to relative suction in a suction zone, the fibers being conveyed in a current of air moving virtually at right angles to the surfaces of two counter-rotating friction discs having narrowly spaced opposing faces defining a gap. From the suction zone, the staple fibers are transferred, generally at right angles to the axis of the current of air, into the gap. The continuous filament is united with the staple fibers in the suction zone, and both components are twisted in the gap between the counter-rotating friction discs.

摘要: Pressure between rollers in each set thereof in a drawing frame is maintained by oil pressure in a main pipe circuit connected to piston and cylinder assemblies allocated to the sets of rollers. A motor driven pump feeds oil from a tank through a feed pipe to the main circuit except when a first solenoid-controlled valve directs the oil through a first return-flow pipe branched from the feed pipe. So long as a pressure gauge connected to the main circuit is indicating the pressure to be below a minimum, it excites the first solenoid-controlled valve to close the first return-flow pipe. When, as a result of lapping on a drafting roller the gauge indicates a maximum pressure, it causes the machine to stop. A second solenoid-controlled valve has its excitation periodically suppressed to open a passage through a second return-flow pipe to prevent the temperature of the drawing frame from overheating the main pipe circuit.
