Abstract: A traveler is formed by a base material consisting of hard steel wire, a nitrogen compound layer, and a sulfide layer such that the nitrogen layer is on the base material side. The nitrogen compound layer and the sulfide layer are formed by executing sulphonitriding treatment on the hard steel wire bent into a traveler shape. The borders between the base material, the nitrogen compound layer, and the sulfide layer are diffused. The spinning machine traveler is used without a running-in operation even when spinning operation is performed at an ultra high spindle rotational speed in excess of 25,000 rpm at the initial use of the traveler, and the service life is also elongated.

Abstract: The ring traveler (10) according to the invention has a noncoated core (20) which consists of iron material and which is provided with an, if appropriate, multipart nitrided edge layer (23; 24) at least in the region of the running surfaces (1) with which said core slides on a ring of a ring spinning or ring twisting machine.

Abstract: The present invention is related to a pneumatic control ring (1) with application in ring twisting machines, continuous spinning frames, and double twisting frames, made of sintered, porous material and with a chamber (4) in which an air-lubricant mixture is pressure injected, which creates an air cushion between the ring (1) and the thread and produces constant and homogeneous lubrication in the contact area between them, in order to avoid the balloon effect and to prevent the thread from wearing down by friction against a surface which is the balloon control ring, facilitating high speed thread processing.

Abstract: The invention relates to a refrigerating-lubricating cursor ring that can be used in ring twisting machines, continuous ring spinning machines and double twisting machines. Said ring serves as a guide for a cursor (3) and comprises a cylindrical, hollow ring (1) made of a porous material, said ring being provided with chamber (6) into which an air-lubricant/refrigerant mixture is injected by pressure, thereby creating an air cushion between the ring (1) and the cursor (3) that prevents mutual friction, lubricates the contact area between said ring and cursor and cools them to prevent wear and heating of the ring (1) and cursor (3) at high speeds. This makes it possible to significantly increase the working speed of the rings in twisting and continuous spinning machine.

Abstract: A spinning ring, in which a ring flange portion 101 making a track permitting a ring traveller to run thereon is divided into an inner flange 103 and an outer flange 106, the inner flange 103 is continuously formed from a sheet steel, the outer flange is formed together and integral with a ring neck portion 109 and a mount portion 102 by cutting, the inner flange 103 and the outer flange 106 are secured to each other by a securing means, and a ring flange portion 101 is provided in an upper portion of the spinning ring 100. The spinning ring enables enhancing the ring flange portion in accuracy and wear resistance, and preventing fine vibrations of the ring flange portion from causing abnormal wear of and shortening of service life of a ring traveller and the ring flange portion and frequent yarn breakage leading to reduction in productivity and falling-off of the ring flange portion due to shock.

Abstract: Disclosed is an improved ring and traveller system for spinning and twisting frames. At least the surface of the ring coming into contact with the traveller consists of a polycrystalline ceramic material and the ceramic surface of the ring has a surface structure with rounded grain boundaries which form a storage volume for a self-generating lubricating film of fibers. The traveller consists of a resilient carrier material, especially metal, and has a metal and/or ceramic surface, the hardness of which is greater than the hardness of the ceramic surface of the ring.

The particular composition comprises an iron replacement composition such as copper selenide. The coating may be applied to rings and travelers in thicknesses of from about 0.001 mils to about 0.05 mils.

Abstract: A process and apparatus for lubricating a ring traveler of ring spinning or ring twisting frame is disclosed in which lubricant is supplied to the ring traveller (18) and to the contact surface between the spinning or twisting ring (12, 16) and the ring traveller (18) from a lubricant store (24), which is disposed on the inside of the spinning or twisting ring (12) and which is provided on its upper side with lubricant outlet openings. The air current which rises during the spinning or twisting serves to convey the lubricant. Such lubrication makes it possible to operate the ring traveller (18) at a greater rotational speed, without increasing its wear. The productivity of the machine is thus increased by this a greater rotational speed.

Abstract: For improving the lubrication of the rotary rings in spinning and twisting frames, a device is provided which is composed by an annular oil reservoir formed in the ring carrier immediately below the stator body, the bottom edge of the rotor body projecting into the oil reservoir and being at a distance from the inner wall of the reservoir so as to form an air passage through which atmospherical air can be drawn into the reservoir when the ring is rapidly rotated: an atomization of the oil is thus originated and the airborne oil particles may reach all the points to be lubricated.

Abstract: A twister ring lubricant is formulated using a major portion of paraffin wax and a minor portion of conventional oil or grease. In the manufacture of ply which is used in making cord, the individual filaments are fed through the eye of a nylon traveler which spins around a steel twister ring.

The twister ring lubricant reduces the sliding friction between the nylon traveler and the steel twister ring.
