Definitions

  • the metallic body has an inner peripheral region where the plastic ring is located to be supported by the metallic body, and at this inner peripheral region the metallic body is formed with a circumferential cavity communicating with a source of lubrication.
  • the metallic body is also formed with a plurality of ducts communicating with this circumferential cavity and leading therefrom to an exterior surface of the metallic body, so that part of the lubricant will discharge onto the latter exterior surface to form a film which will lubricate the contact between the traveller and the lower annular surface of the metallic body.
  • the present invention relates to the spinning of yarn.
  • the present invention relates to the spinning of yarn on ring spinners where the yarn is twisted while the bobbin rotates with 'the yarn being displaced along an annular ring by a traveller which moves around and slides along this ring.
  • the invention relates in particular to a ring spinner of this type where the ring is made of a plastic, such as a synthetic polymer, while the body which supports the ring is made of metal.
  • the ring In order to avoid any possible damage to the plastic ring, particularly at its edges when the traveller is assembled with the ring, it is essential that the ring does not extend beyond the confines or outer limiting edges of the metallic body which carries the ring.
  • the inner peripheral surface of the ring forms the primary contact surface for the traveller which slides on the synthetic polymer material of the ring. This material has excellent sliding properties for the traveller.
  • the traveller slides in a highly advantageous manner along the inner periphery of such a ring made of a plastic such as a synthetic polymer material
  • the traveller also slides along a lower annular surface portion of the metallic supporting body which carries the ring, and at this location there is a secondary annular area of sliding contact where metal slides on metal because both the supporting body for the ring and the traveller itself are made of metal.
  • this secondary area of sliding contact for the traveller there is friction between metal rubbing on metal.
  • Yet another object of the present invention is to provide a construction which will reliably prevent any of the lubricant from being spattered on the cop, so that the ring spinner of the invention may be used for spinning both wool and cotton. Soiling of the cotton with spattered oil is, as is well known, particularly undesirable with respect to subsequent processing of the yarn, and this disadvantage is avoided with the structure of the invention which prevents spattering of oil.
  • An additional object of the present invention is to provide a construction which enables a wick in a lubricating cavity of the metallic body to be inserted into the latter cavity after the ring is mounted on a part of the metallic body, so that undesirable displacement of the wick, which frequently takes place when the ring is mounted after the wick is located in the cavity, can be avoided.
  • the plastic ring has an inner peripheral surface slidably engaged by the rotary traveller.
  • This plastic ring is carried by a metallic body at an inner peripheral region of the latter.
  • This inner peripheral region of the metallic body is formed with a circumferential cavity which communicates with a source of lubricant.
  • the metallic body is formed with a plurality of ducts communicating with this cavity and discharging onto an exterior surface of the metallic body so that a film of lubricant will become located at this exterior surface of the metallic body.
  • the traveller slidably engages a lower annular surface portion of the metallic body, and the lubricant which discharges onto the exterior surface of the metallic body forms a film lubricating the secondary area of contact between the traveller and the lower annular surface of the metallic supporting body.
  • the ring spinner illustrated therein includes a metallic body I which has an inner annular region where the metallic body 1 carries the plastic ring 2 which is made of a plastic such as a synthetic polymer material.
  • the metallic ring-supporting body I is made of one piece of metal, whereas in the embodiment of FIG. 2 the ring-supporting body is made of lupper part I a and a lower part lb.
  • This lower part lb of FIG. 2 is formed with the stepped inner peripheral region 3 providing the upwardly directed shoulder which receives the lower outer peripheral region of the ring 2 so as to support the latter.
  • the upper part 1a extends over the top surface of the ring 2, in the embodiment of FIG. 2, and the body parts la and lb are held together by screws 4. It will be noted that with the one-piece body embodiment of FIG. 1 the ring 2 also is mounted on an upwardly directed shoulder forming part of the stepped inner peripheral region 3 of the body 1.
  • a traveller 5 slides in a well-known manner along the inner peripheral surface of the ring 2, being pressed against this inner surface by centrifugal force during operation of the spinner.
  • the contact surface 6, shown by a heavy line in FIGS. 1 and 2 forms the primary area of sliding for the traveller 5 where the traveller 5 engages the inner peripheral surface of the ring 2 which has excellent sliding properties. as pointed out above.
  • the inner peripheral region of the metallic supporting body of both embodiments is formed with a circumferential cavity 8 which surrounds the ring 2 and which communicates through a pasage 9 with a lubricant supply which is not illustrated.
  • the metallic supporting body of both embodiments is formed with a plurality of ducts 10 communicating with the lower portion of the cavity 8 and leading therefrom to the exterior surface of the metallic supporting body. It will be noted that this exterior surface onto which the ducts l discharge is of a frustoconical configuration situated outwardly beyond and extending upwardly from the secondary area of contact 7 between the traveller and the ring-supporting body.
  • axes of the ducts form elements of a cone whose apex is situated in the central vertical axis of the ring spinner.
  • the cavity 8 isfilled with a woolen wick 11 which is loosely coiled in the cavity 8 and extends out through the passage 9.
  • Felt blocks or pads 12 fill up the ducts 10.
  • the lubricant flows out through the ducts 10 to reach the exterior lower frustoconical outer surface portion of the metallic ring-supporting body, and due to gravity and capillary action a film of lubricant covers not only the exterior outer frustoconical surface of the metallic ring-supporting body but also the lower annular surface region 7, and the inner surface situated inwardly of and extending upwardly from this lower annular surface 7 is also lubricated with the film of lubricant as the result of capillary action.
  • the secondary surface area 7 is very effectively lubricated and the lubricant will very reliably become situated at the particular location of the secondary surface 7 irrespective of any changes in this location due to wearing of the parts.
  • the wick 11 is first coiled into the circumferential cavity 8 of the metallic body 1. Then the ring 2 is inserted into the body 1, so as to enclose the wick within the cavity 8.
  • the wick 11 is coiled into the circumferential cavity 8 which is still accessible because the top of the cavity has not yet been covered by the upper body part la.
  • the top body part la is fastened to the lower body part lb by the screws 4.
  • the supply of the lubricant onto the exterior outer frustoconical surface of the metallic ring-supporting body prevents the lubricant from being spattered onto the cop, so that the ring assembly may be reliably used for spinning both wool and cotton without any danger of soiling the yarn to undesirably afiect the subsequent processing thereof.
  • FIG. 2 The embodiment of FIG. 2 according to which the metallic ring-supporting body is composed of a pair of parts is of particular advantage since it makes the assembly much easier, particularly with respect to the lubricating wick 11.
  • the lubricating wick is prevented from being undesirably displaced or carried away when the ring is assembled with the supporting body.
  • FIG. 1 where the ring 2 is necessarily assembled with the body 1 after the wick 11 has been coiled into the cavity 8 it is possible for the ring to engage the wick and undesirably displace it.
  • a spinning ring assembly comprising a spinning ring and a traveller which travels thereabout, a plastic ring having an inner surface along which the traveller slides, and a metallic body having an inner peripheral region carrying said plastic ring, said inner peripheral region of said metallic body being formed with a circumferential cavity communicating with a lubricant supply, and said metallic body being formed with a plurality of ducts communicating with said cavity and leading therefrom to an exterior surface of said metallic body.
