Definitions

  • This invention relates to apparatus for continuously winding filamentary material such as yarns, tows and monofilaments at high speed into smooth ended cylindrical packages.
  • yarns is used herein in a broad sense to include all filamentary material capable of being wound onto a bobbin.
  • the yarn In the flat winding of yarn, the yarn is frequently directed onto a rotating receiving bobbin by a guide which reciprocates in an axial direction in an attempt to produce a constant helix angle of lay of yarn on the bobbin and thereby produce a uniformly cylindrical package.
  • Examples of prior art apparatus include those in which the guide is controlled by a cam, generally of the barrel type, having a linear track on a majority of its periphery to impart a constant guide velocity axially of the package. Additionally, a short parabolic or otherwise curved sec tion is provided connecting the straight portions of the cam track. The curved section etfects the desired reversal at the end of each package traverse.
  • Other examples include those having various counterbalancing weights and springs mounted on the guide which efiect a speed-up of the guide with respect to the cam follower as the follower slows for a reversal.
  • Another object of the invention is to provide a novel guide system in which the yarn is guided from the outer end of an ela-stomeric mass which is secured to a cam operated traverse bar.
  • Yet another object of this invention is the provision of a yarn guide comprising a pair of clastomeric legs projecting outwardly from a traverse bar, including means for guiding the yarn between the outer ends of the resilient legs and stop means mounted adjacent the legs to limit the pivoting of the legs.
  • a further object of the invention is to provide a guide of the type described in which the mass, length and composition of the guide legs and the positioning of the stop means is such that the guide will be substantially critically damped and thus will not repeatedly oscillate after changing direction at the end of the package.
  • a more general object of the invention is to provide a guide of the type described in which the yarn guiding means will continue to travel in its direction at a substantially constant speed for a short space of time after the traverse bar has reversed its direction with respect to the package being wound.
  • FIGURE 1 is a perspective view of the novel yarn guide mounted on a traverse bar:
  • FIGURE 2 is a sectional view taken substantially along the line 2-2 of FIGURE 1;
  • FIGURE 3 is a sectional view taken substantially along the line 33 of FIGURE 2 (the traverse bar having been removed for clarity).
  • a thread guiding system embodying the principles of this invention is indicated at 10 carried on a traversing bar 12, adjacent the filament receiving package of a conventional high speed winding machine (not shown).
  • the traverse bar 12 is mounted with its longitudinal axis paralleling that of the receiving package and is arranged to reciprocate axially of the package preferably in a horizontal plane.
  • a plurality of guiding systems 10 are mounted on the bar 12 in side by side relationship to guide thread onto a plurality of packages.
  • the bar 12 is preferably reciprocated as by a pin 16 and barrel cam 18 arrangement although the particular form illustrated is merely exemplary being that any means can be employed that will cause the bar to reciprocate axially of the package with a constant speed and a relatively sharp reversal of direction. It is desirable that the bar be moved at constant velocity so that the thread guide will deposit an even lay of filament from one end of the package to the other.
  • the novel guide assembly includes a beam moulding 20, a carrier 22 and a thread guide 24.
  • the beam moulding 2%? is composed of an elastomeric material such as Vulcaprene dipped black butyl rubber having a shore hardness of Of course the exact dimensions and composition of the moulding will depend on the speed and length of the oscillation for which the particular guide system is designed so that the guide will be substantially critically damped as to eliminate repeated oscillation after a revcrsal.
  • the moulding generally comprises a pair of slightly spaced opposed L-shaped legs 26 integrally projecting from a base portion 28 formed of the same material. As" shown the ends 30 of the legs 26 are directed toward one another as to leave smooth faces 32 at the inner extent of each.
  • the thread guide 24 comprises an arcuate segment of a more rigid material suchas mild steel.
  • the thread guide 24 preferably is bent twice adjacent its arcuately outer ends to form L-shaped tabs 31. Adjacent its midpoint, the guide has a circular opening 33 formed therethrough so close to the outer arcuate periphery 34 of the guide as to intersect it and provide an en rance 36 to the opening. Additionally, one or more additional holes 38 maybe formed through the guide to receive a locating tool during the fabrication of the guide system as more fully set forth hereinafter.
  • the carrier 22 as illustrated especially in FIGURES 2 and 3 comprises a generally rectangular plate 44) having a generally rectangular opening 42 formed through the central portion thereof; a U-shaped section 44 having two opposed inwardly directed legs 46 spaced apart by an outer lateral portion 48 having a rectangular opening 5t ⁇ formed therethrough, similar in orientation and dimension to opening 42; and a generally Y-shaped stop member 52 which projects through the openings 54.
  • the three portions of the carrier 22 are associated with one another as by spot welding so that the opening 50 through the -.U-shaped section 44 directly overlies the opening 42 through the rectangular plate and the Y-shaped portion projects through the superposed openings and has its singular leg 56 outermost.
  • the Y-shaped stop preferably has a laterally directed tab 58 at the outeriend of each paired leg 66 which is secured as by spot welding to the inner surfaces of the lateral portion 48 adjacent the periphery of the hole 543.
  • the guiding system It) is preferably assembled by conventional moulding techniques which may include apand the bobbin caused to rotate at a constant high speed.
  • the cam 18, which may be driven from the winding apparatus, engages the pin 16 and causes the bar 12 carrying the novel guide assembly 10 to oscillate back and forth along the package at a constant speed, depositing a uniform lay of filament with each pass.
  • the movement imparted to the guide is best shown by the following summation.
  • the guide is carried in the null position shown in the figures at a constant sped intermediate the end points of its path.
  • composition can be cured and the beam 20 coated with a suitable antioxidizing compound to extend the useful life of the assembly.
  • the Y-shaped stop 52 of the guide system has its singular leg 56 in position midway between the smooth end surfaces of the spaced outer portions 30 of the beam L-shaped legs 26.
  • the guide assembly 10 is suitably mounted to the traverse bar 12 by receiving the bar in the U-shaped section 44 and securing it there by bolts 62. which pass through the inner portions of the legs 46 and over the bar 12 damp out, not only any tendency of the guide to oscillate but also to absorb vibrations in the traverse bar itself, which, due to its length and mass even when made of steel, is not completely inelastic suffering a small degree of compression and extension as it oscillates to and fro.
  • the beam portion of the guide assembly is preferably composed of high hysteresis butyl rubber it is contemplated that other natural or synthetic elastomeric materials having the property of quick, nearly complete recovery after flexure could be used.
  • a high speed winding apparatus for collecting filamentary materials on a rotating package comprising: a traverse bar disposed in a direction parallel to the axis of rotation of said package; means for reciprocating said traverse bar in said direction, filamentary guide means carried by said bar adjacent the package, said guide means comprising an elongated flexible elastomeric portion projecting outwardly from the bar and means mounted on the elastomeric portion adjacent the outer extent thereof for slidingly guiding a yarn for winding on the package.
  • Apparatus as set forth in claim 1 wherein the elastomeric portion comprises two opposed L-shaped legs projecting from said bar as to have the outer portions of the legs directed toward one another, and wherein the yarn carrying means comprises a rigid member secured to each of the legs and arranged to carry a yarn outside and between the outer extent of the legs.
  • Apparatus as set forth in claim 1 additionally comprising positive means fixedly secured with respect to the bar and positioned with respect to the legs to limit the flexure thereof to a predetermined degree.
  • stop means comprises a rigid member positioned between the opposed L-shaped legs.
  • a rotating package a tra erse bar extending in a direction parallel to the rotational axis of the package; means reciprocating the traverse bar axially of the package so that the velocity of the bar is substantially constant between the end points of the reciprocation; a flexible beam mounted on the bar adjacent the package as to extend transversely from the bar; means mounted on the beam adjacent the outer extent thereof for guidingly engaging a yarn for winding on said package, the beam being of such flexibility that the yarn guiding means continues to travel at substantially constant velocity in a first direction for a finite period of time subsequent to the change in direction of the bar at the end .point of a reciprocation.
  • Apparatus as set forth in claim 6 additionally comprising positive stop means fixedly positioned w'ith respect to the bar to limit the flexure of the beam after the bar direction change.
  • the beam comprises a pair of opposed L-shaped legs depending from the traverse bar; the filamentary guide means is secured to each leg adjacent the outer extent of the legs; and the stop means comprises a rigid member positioned between the legs as to be equally spaced from each leg when the legs are unfiexed.
