Definitions

  • My invention relates to winding machines for producing cross-wound yarn packages, such as cheeses and cones, in which the oncoming yarn is passed upon the yarn package by means of a rotating yarn guide which shifts the yarn back and forth along the package. More particularly, the invention concerns Winding machines in which the two travel limiting stop members are mounted in fixed positions at the rotating yarn guide near the two mutually spaced localities where the oncoming yarn being reciprocated along the yarn package, reverse its direction.
  • the limit stops serve to prevent the yarn from flinging beyond the respective lateral, diametrical planes of the yarn-guiding drum at the reversing locations, in the event the yarn supply is interrupted by tearing of the yarn or depletion of a yarn-supply coil so that the yarn is no longer kept taut on its travel to the guiding drum and, under its own inertia, tends to pass beyond the lateral confines of the guiding drum. If this happens, a so-called throw off may occur, ie the loose yarn end flung beyond the guiding drum may be placed over the lateral face of the yarn package instead of onto the peripheral usrface, or the loose yarn end may become wound about the core of the package.
  • the deflector means extend substantially parallel to the axis of the rotating yarn guide, at least in the region of the above-mentioned reversing localities where the yarn, reciprocating along the yarn package or take-up spool, reverses its stroke direction; and the yarn deflector means are mounted in such a position that the geometric ex- "ice tension of the yarn path on which the oncoming yarn travels toward the deflector means does not intersect the drum or the travel-limiting stops but passes by the drum at a radial distance therefrom and in spaced relation from the limit stops.
  • the yarn-travel deflector means which may be mounted, for example on a bar inter-connecting the two travel-limiting stops, is arranged only in the respective vicinities of the reversing localities because the danger of throw-off turns exist only in these regions.
  • the additional yarn deflecting means extend from one to the other reversing locality of the yarn-guiding drum.
  • the yarn end which in the event of yarn breakage may fling upwardly will whip on a substantially straight line which coincides with the geometrical extension of the yarn travel direction and passes at a radial distance from the drum and the limit stops.
  • the yarn is then caught by one of the limit stops at the reversing localities and passes along a guiding edge of the stop toward the middle of the reciprocating stroke.
  • the yarn is ultimately guided toward the middle of the yarn package and can no longer pass between the limit stops and the yarnguiding drum, thus being prevented from flinging beyond the axial ends of the take-up spool.
  • the yarn deflector means are provided with at least one abutment approximately tangential to the yarn at a reversing locality of the reciprocating stroke. It is particularly advantageous to provide two such abutments at the respective two reversing localities so that they limit the reciprocating stroke of the oncoming yarn at the deflector means and hence before the yarn reaches the above-mentioned stop members.
  • the yarn is permitted to reciprocate only along a stroke length as required for the winding operation so that the yarn is prevented from flinging outwardly eevn before the yarn reaches the travel-limiting stop members.
  • the abutments of the deflector means can be upwardly extended so as to form a deflector contour upwardly inclined toward the middle of the stroke of reciprocating yarn motion. This affords most reliable assurance of having the yarn, when it whips upwardly, in the event of yarn breakage, guided by the abutment contours toward the middle of the guiding drum, thus aiding the effect of the hook-shaped limit stop members located more closely adjacent to the guiding drum.
  • FIG. 1 is a front view of a guiding drum with a yarn package being wound with the aid of a device according to the invention.
  • FIG. 2 is a side elevation of the assembly shown in FIG. 1;
  • FIG. 3 shows a View similar to that of FIG. 1 of a modified device.
  • a yarn package 2 being Wound has its peripheral surface resting upon the cylindrical surface of a guiding drum 1 whose shaft, during winding operation, is driven at constant speed thus frictionally entraining the package for rotation at constant peripheral speed.
  • the yarn F passes from a supply coil (not shown) through a yarn cleaner and tensioner (both not shown) along a fixed guide 7 which, together with the other illustrated components, defines a path for the yarn travelling onto the guiding drum 1 and thence onto the yarn package.
  • the guiding drum 1 is provided with a guiding groove 6 through which the yarn passes.
  • the guiding groove extends peripherally about and longitudinally along the drum and forms a loop closed upon itself so that the oncoming yarn is reciprocated along the guiding drum and hence along the yarn package as the package is being wound.
  • the yarn is twice reversed in its stroke direction at the axially outermost reversing points of the guiding groove 6.
  • the device is provided with two fixed limiting stop members 3 which are upwardly inclinde toward the middle of the stroke and terminate in a hook 4.
  • the stop members 3 have an arcuate shape and extend in close proximity to a peripheral portion of the drum as is apparent from FIG. 2.
  • the yarn passes over an additional yarn deflector 5 consisting of a glide bar which extends parallel to the drum axis along the entire length of the reciprocating stroke between the limits of the two yarn positions denoted in FIG. 1 by F and F respectively.
  • the deflector bar is rigidly joined with the structure that forms the stop members 3 and protrudes from the stop members 3 so that the yarn end, in the event of yarn breakage, can fling upwardly past the guiding drum 1 or the yarn package 2 and past the stop members 3.
  • the additional deflector means do not extend over the entire range of the reciprocating stroke determined by the limit positions F and F of the yarn, but are formed by two guides 10 located only in the vicinity of the respective reversing points where the danger of throw-off turn exists.
  • Each guide 10 is upwardly extended to form an abutment 11 which tangentially almost touches the yarn during stroke reversal, i.e. in the yarn position F or F.
  • the abutments 11 permit the oncoming yarn to reciprocate only along the stroke length required for passing the yarn back and forth along the package, but prevent any further lateral travel of the yarn as may otherwise occur in the event of insuflicient yarn tension of similar irregularities.
  • Each abutment 11 has a deflecting contour inclined toward the middle of the stroke. If the yarn breaks while it runs near a reversing locality, the adjacent deflector contour of the abutment 11 guides the upwardly Whipping yarn end toward the middle of the stroke thus aiding the function of the travel limiting stop members 3.
  • the invention is not limited to the illustrated embodiments.
  • the additional yarn deflector means may also be given a different design, for example in the form of rails, edges, deflector surfaces or the like, and they may be disposed on other places of the machine frame structure.
  • a yarn-package winding device comprising a moving yarn guide for passing the yarn onto the package being wound, said yarn guide having means for reciprocating the oncoming yarn along the package, yarn engaging means spaced from said yarn guide along a length of the oncoming yarn for constraining the length of yarn in a given travel path toward said yarn guide, two normally fixed stop members mounted closely in front of said moving guide near the respective reversing points of the yarn reciprocating stroke and having guide contours inclined toward the middle of the stroke for reducing lateral throw of yarn ends in the event of yarn interruption, said yarn engaging means comprising yarn deflector means extending transverse to said yarn path and substantially in a direction parallel to the reciprocating stroke so as to be engageable by the oncoming yarn ahead of its engagement with said yarn guide for deflecting the oncoming yarn from a first travel path portion to a second travel path portion transverse to said first travel path portion, said yarn deflector means being located near said respective reversing points and spaced from said stop members in a direction opposite to that of said yarn guide, the geometrical extension of
