Definitions

  • the present invention overcomes the difficulties and deficiencies encountered by such prior arrangements, and additionally provides other advantages and benefits, by severing textile fabric with high velocity impingement of a heated fluid.
  • Such severance of textile fabrics proceeds irrespective of whether the fabric is composed of yarns which are fully thermoplastic in nature, blended thermoplastic and natural fiber, or wholly natural fiber.
  • the high velocity heated fluid stream is not subject to becoming dulled and does not accumulate deposits of textile material so as to loose efficiency.
  • the compressed air, on contacting of the textile fabric, is to be at a temperature at least sufficient to soften any thermoplastic content of yarns forming the fabric and be moving at a velocity at least sufficient to separate the softened yarns.
  • a further object of this invention is the formation of a smooth edge along a fabric by the severance of yarns forming the fabric through high velocity impingement of the heated fluid stream thereagainst.
  • a sealed edge having ravel resistance characteristics is obtained by the softening and adhesion of the yarns in accordance with the method of the invention.
  • FIG. 1 is a perspective view of one textile fabric forming apparatus incorporating a fabric severing means in accordance with this invention
  • FIG. 2 is an enlarged plan view of a portion of the apparatus of FIG. 1, illustrating the apparatus of this invention
  • FIG. 3 is an elevation view, partially in section, taken generally along the line 33 in FIG. 2;
  • FIG. 4 is an elevation view, partially in section, taken generally along the line 4-4 in FIG. 2;
  • FIG. 5 is an enlarged fragmentary view, partially in section, taken generally along the line 55 in FIG. 4.
  • FIG. 1 The accompanying drawings illustrate the anticipation that this invention is useful with a textile loom (generally indicated at 10 in FIG. 1) of the shuttleless type in which textile fabric is formed by the delivery of warp yarns by warp handling instrumentalities and the insertion of weft yarns into the warp yarns by weft yarn carrier instrumentalities.
  • One conventional type of shuttleless textile weaving machine to which this invention has been applied is the Draper DSL machine commercially available in the United States from the Draper Division of Rockwell International. It is believed that machines of this type are generally known to persons working in the textile industry and, for that reason, detailed description of the DSL apparatus and its operating instrumentalities will not be given here.
  • Fabric F produced on the loom 10 moves from the fell at which warp and weft yarns are interwoven toward a breast beam 11 of the loom, with a side edge portion of the fabric engaging the temples 12 (FIG. 2). Adjacent the breast beam 11, the fabric is passed about a take-off or sand roll 14, which maintains the fabric in tension and aligned with a predetermined path of travel (FIG. 3). As will be pointed out more fully hereinafter it is an important feature of this invention that the fabric be tensioned and guided along a predetermined path of travel.
  • the loom has mounted thereon means for severing the fabric F adjacent a longitudinal side edge thereof.
  • the severing means generally indicated at 15, directs a heated fluid stream to impinge against the fabric at high velocity, so as to sever the fabric as described more fully hereinafter.
  • the pressurized fluid employed is a compressed gas and particularly, compressed air. Air was chosen for use in an operating embodiment from which the present drawings were taken due to the usual availability of compressed air in textile mills.
  • the air is delivered to the severing means through a conduit 16 which is suitably connected with an appropriate source (as schematically illustrated in FIG. 1).
  • the severing means 15 includes a thermally insulating casing 18 within which is positioned an electrical resistance fluid heater l9 having resistance wires 20 about which compressed air is directed to flow (FIGS. 4 and 5). Electrical current is supplied to the resistance wires 20 through suitable conductors 21, 22 from a suitable source (schematically illustrated in FIG. 1). As was the case with the selection of compressed air delivered from an appropriate source, selection of an electrical resistance heater means was influenced by the usual availability of electrical current in textile mills.'Other gases or heaters may, of course, be adapted to the present invention.
  • Heated compresed air passing from the electrical heater 19 is directed, by an outlet conduit 24, toward the predetermined path in which the fabric F is guided and against a portion of the fabric which is under tension.
  • the location of impingement is spaced inwardly from a side edge of the fabric (FIG. 2).
  • the heated air flow is directed to impinge upon the fabric F at 90 to the path of movement thereof (FIGS. 3 and 4).
  • the fabric F passes above an underlying support plate 25, which has an opening therethrough for passage of the air stream.
  • the impingement of the heated air stream severs the yarns of the fabric F.
  • the yarns of the fabric are predominantly or wholly thermoplastic materials, softening of these yarns assures production of a ravel resistant edge along the resulting longitudinal side edge of the fabric F.
  • the support plate 25 and the casing 18 of the severing means 15 are maintained in operative position by a mounting bracket 26 secured to the breast beam 11 of the loom 10 by appropriate fastener means.
  • Polypropylene will soften in a range of from about 275 to about 330 Fahrenheit and will melt in a range of from about 320 to 350 Fahrenheit. These temperature ranges may be considered as representing ranges in which operation in accordance with the present invention will occur and have been contemplated as operative with blends of thermoplastic and natural fiber and with natural fiber alone. Early experimentation with arrangements as contemplated by the present invention obtained satisfactory operation with such a range of fabrics at temperatures of at least about l,000 Fahrenheit. Typically, where an electrical resistance heater such as the heater 19 is employed, the application of voltages on the order of 40 to volts to a heater rated at 500 watts when operated at 110 volts will achieve the necessary temperatures.
  • the unheated velocity was approximately l0,000 feet per minute. With the application of approximately 55 volts the air was heated to a temperature of approximately 520 Fahrenheit and the velocity was increased to about 12,500 feet per minute.
  • One example of a material which has been satisfactorily severed in accordance with this invention, while being formed, is a relatively light weight shirting constructed with a plain weave having 44 warp ends per inch and 40 picks per inch.
  • both warp and filling yarns were a 250 denier zero twist bright polyester. Satisfactory cutting was achieved, with this relatively light weight fabric, at an air pressure of about 0.5 psi and a voltage of about 50 volts.
  • Another example of a fabric satisfactorily severed in accordance with this invention was a 10 ounce ulcery having filling yarns of percent cotton and warp yarns of 65 percent polyester and 35 percent cotton. A limited number of 100 percent polyester warp yarns were introduced at one side edge and medially of the width of the fabric, in order to provide for assured sealing of side edges to be produced in accordance with this invention. Satisfactory severing was achieved at air pressures of approximately 4 pounds per square inch and applied voltages on the order of 50 volts.
  • a method of severing a length of textile fabric comprising the steps of moving fabric along a predetermined path of travel while imposing on the fabric forces tensioning the fabric in the plane of the path and while contacting one face of the fabric to restrain the fabric against movement in one direction transversely away from the plane of the path, delivering a flowing stream of gas while heating the gas stream to an elevated temperature and while directing the heated gas stream in the one direction for impingement against the moving and tensioned fabric at a location generally opposite the restraining contact therewith, and severing the fabric with the heated gas stream.
  • a woven textile fabric which includes at least some thermally degradable yarns, the fabric having at at least one edge successive separated weft yarn ends protruding therefrom and said loom having means for moving the fabric along a predetermined path of travel from the fabric forming location and means for imposing on the fabric forces tensioning the fabric in the plane of the path of travel; means for severing the fabric along a warpwise longitudinal line spaced inwardly of but adjacent to said one edge, said severing means comprising thermally insulating housing means mounted on said loom, means for supplying a flowing stream of noncombustible gas, means mounted within said housing means for receiving the gas stream and for heating the same to an elevated temperature of at least about 500F., and means for directing the heated gas stream transversely of said plane of the path and for impinging the heated gas stream against a face of the tensioned fabric at a velocity of at least about 6,000 feet per minute to
