Abstract: A method for manufacturing a twisted yarn includes the step of removing two rovings from two separate supplies and passing each roving through a separate drawing device. From each roving a separate spun yarn is produced by ring-spinning. Each spun yarn is collected in the form of a bobbin on a yarn carrier of separate hollow spindles, wherein the separate hollow spindles are positioned atop one another. With formation of a yarn balloon the spun yarn is withdrawn from the bobbins and guided through the hollow spindle axle of the respective hollow spindle. The spun yarn withdrawn from the upper one of the hollow spindles is guided through the hollow spindle axle of the lower one of the hollow spindles. Both spun yarns are then guided together to a winding device positioned below the lower one of the hollow spindles. The hollow spindles are rotated as a function of the winding speed of the winding device such that a twist of the spun fibers is at least partially canceled.

Abstract: A spinning ring member supported on an air bearing between the ring member and a ring holder, the air bearing being formed by an axial passageway between the ring holder and the ring member and upper and lower radial passageways. The upper radial passageway is open and unencumbered, and a barrier element is disposed directly in the path of the air flow through the lower radial passageway to interfere with and partially block such air flow, whereby pressurized air within the axial passageway will flow primarily through the upper radial passageway to impose a lifting force on the ring member. The upper and lower radial passageways are provided by upper and lower facing radial walls on the ring member and the ring holder, respectively, that have an equal axial spacing therebetween to provide simultaneous seating of the ring member at both radial walls when the ring member is at its inoperative or at rest position.

Abstract: The invention relates to a bearing housing for driven and air-suspended spinning rings on ring-spinning and ring-twisting machines, whereby a tape drive with tensioning pulleys is provided for the spinning rings. The object of the invention is to decrease the amount of material and working time when the bearing housings are attached (applied) to the ring rail and to shorten the time required for the adjustment of the spinning rings and of the tensioning pulleys. The technical task which is being solved by the invention is constituted by the fact that the number of fastening elements needed for the attachment of the bearing housings to the ring rail is decreased and that the spinning rings are not individually adjusted and that the tensioning pulleys are not adjusted at all. According to the invention, this is accomplished by having at least two spinning rings (2;3) and one tensioning pulley (5) arranged on one bearing housing (1).

Each opening receives a fastener, the fastener extending through the opening and connecting the support to a ring rail. Between the support and the ring rail is a bushing of resilient material which isolates the support from the ring rail so that no portion of the support touches the ring rail and no metal portion of the fastener touches the ring rail. The assembly allows slight movement of the ring with the traveler.

Also the inner ring and/or the spinning ring are provided with at least one slot-opening by means of which traveller debris can escape. Furthermore the distance of the outer upper edge of the inner ring from the traveller guide surface is to be chosen sufficiently large, so that upon restarting of the winding process the traveller does not collide with the inner ring.

Abstract: Each revolving ring of a continuous-spinning frame for textile yarn is mounted on a fluid bearing and driven in rotation by a ring traveler. The resisting torque of the ring is intentionally increased by means of hollow or projecting portions such as fins formed on the ring in order to produce a difference in speed between the normal speed of rotation of the spindle and the speed of rotation of the ring. The result thereby achieved is to ensure uniform tension of the yarn and to improve operating stability of the spinning frame.

Abstract: A free-floating ring is disposed in an annular chamber between a fixed outer ring based on the ring rail and an inner ring which is adjustable up and down axially in relation to the outer ring. The outer ring has circumferentially spaced camming slots in its side wall slidably receiving radial cam pins fixed to the inner adjustable ring. One such cam pin on each inner ring is extended to engage slidably within a slot in an actuating bracket secured to a shifter rod extending longitudinally of the ring rail and guided within bearings on the ring rail. Movement of the shifter rod longitudinally of the ring rail in one direction or the other produces raising or lowering of the gang of inner rings to vary the yarn tension. An opening for yarn threading is provided in the annular side wall of each outer ring.

The flange, bridge and ring body are further configured and dimensioned so that the upper surface of the traveler body is substantially flush with the upper surface of the ring body when the traveler is resting on the flange.
