Definitions

  • a yam heater for heating a plurality of yarns in a multistation yarn processing machine has a single heating unit sandwiched in heat-conducting relationship between two thermally conductive plates, each of which is provided at its side facing away from the heating unit with heater tubes through which the yarn is to pass. These heater tubes may extend in parallelism or at an angle of inclination to an edge of the respectively associated plate.
  • This invention relates to yarn heaters.
  • This invention comprises a yarn heater for heating a plurality of yarns in a multistation yarn processing machine, comprising a plurality of heater tubes on one side of a heat conductive plate, in good thermal contact therewith, and a heating element supplying heat uniformly to the other side of said plate.
  • Said heating element may comprise an electric resistance heating wire or strip embedded in a mat of electrically insulating material.
  • Said mat may be of glass fibre.
  • Said plate may be of a heat conductive metal such as aluminum.
  • the tubes may be in castings bolted or otherwise secured to the plate.
  • the castings may have a iiat face against the said plate and a bore parallel to the face which houses a tubular insert.
  • the castings preferably extend substantially the full length of the plate.
  • the heater tubes preferably have a smooth internal surface, and can be of stainless steel.
  • the heating element may be sandwiched between two heat conductive plates, each having attached tubes, so that the heater lis double sided.
  • the heater may comprise an envelope for the tubes, plate and element, packed with insulating material such as glass bre.
  • the plate may be substantially rectangular, with the tubes parallel to one edge thereof. Otherwise, the tubes may be at an inclination to an edge of the plate.
  • the heater may have a centrally located temperature sensing device for controlling the temperature of the heater.
  • the invention also comprises a multistation yarn processing machine comprising such a heater.
  • a multistation yarn processing machine comprising such a heater.
  • Such machine may be a false twist crimping machine, when the heater may be located with the path of the yarns after the false twisting device, whereby to effect reheating of the false twist crimping yarn.
  • FIG. 1 is a part sectional front elevation
  • FIG. 2 is a plan
  • FIG. 3 is a sectional side elevation showing the location of the heater in a false twist crimping machine
  • FIG. 4 is a part diagrammatic elevation of another embodiment.
  • FIGS. l to 3 illustrate a yarn heater 11 for a plurality ice of yarns 12 in a multistation false twist crimping machine, comprising a plurality of heater tubes 13 on one side of a heat conductive aluminum plate 14, in good thermal contact therewith, and a heating element 15 supplying heat uniformly to the other side of said plate 14.
  • the heating element 15 comprises an electric resistance heating wire or strip 16 embedded in a mat 17 of electrically insulating glass fibre material.
  • the tubes 13 are in castings 18 bolted to the plate 14.
  • the castings 18 each have a llat face 18a against the plate 14 and a bore parallelto the face 18a which houses a tube 13.
  • the tubes 13 have smooth internal surfaces and are of stainless steel.
  • the heating element 15 is sandwiched between two aluminum plates 14, each having tubes 13 so that the heater is double sided.
  • each casting 18 may be attached to its plate by one bolt, and the two plates 14 and the element 15 fastened together by bolts passing through the entire assembly from one casting 18 to a casting 18 on the opposite Iface.
  • the castings 18 eX- tend substantially the full length of the plate 14.
  • the heater comprises an envelope for the tubes 13, plates 14 and element 15, in the form of a sheet metal box 22 packed with insulating material 23 such as glass fibre.
  • the tubes 13 have collars 24 which locate in the top of the box 22.
  • Power is conveniently supplied to the element at a point 25 located centrally of the mat 17, and a temperature sensing element 26 controls the amount of electrical energy supplied to the resistance element 16 to maintain a uniform processing temperature.
  • the heat conductive plates 14 are rectangular, and the tubes 13 are parallel to one edge, which is arranged vertically in the machine. It is, however, possible, as shown in FIG. 3 to mount the tubes 13 at an inclination to the bottom edge of the plates 14, so that relatively long yarn paths can be accommodated within a small vertical extent.
  • the plate 14 can be in the form of a parallelogram as shown, as can also the box 22, if desired.
  • a yarn heater for heating a plurality of yarns in a yarn processing machine comprising a pair of plates of thermally conductive material having respective inwardly directed juxtaposed sides, and respective outwardly directed sides; a single heating device sandwiched between said inwardly directed sides in thermally conductive relationship with said plates; and a first and second plurality of heater tubes provided on the respective outwardly directed sides in thermally conductive relationship with said plates, and adapted for passage of yarns to be heated.
  • a yarn heater as defined in claim 1 further comprising castings of thermally conductive material secured to the respective plates and each having a flat face contacting one of said outwardly directed sides, and a plurality of bores extending in at least substantial parallelism with the plane of said flat face; and wherein said heater tubes are tubular inserts accommodated in said bores.
  • a yarn heater a defined in claim 1, wherein said plates each have at least one edge; and wherein said heater tubes have longitudinal axes which extend at an inclination to said edge.
