Definitions

  • a yarn heater assembly is provided with or formed with an endwise extension of that part of the heater assembly which provides a heating zone for a running yarn or yarns, said endwise extension forming a housing for fume removal means which are thereby incorporated as part of the heater assembly.
  • the endwise extension may be formed to provide an open-sided lengthwise recess which houses a coextensive box-like suction chamber along the length of which the running yarn or yarns travels adjacent one wall of the chamber, said wall being provided with inlet means through which fumes given off by the yarn are drawn into the suction chamber.
  • said inlet means is a slot running lengthwise of the chamber wall.
  • Both ends of a yarn heater assembly may be provided with or formed with an endwise extension each housing fume removal means, or only one endwise extension may be provided at the exit end of the heater assembly as regards the direction of yarn travel.
  • the elongated heaters currently in use are usually located in a processing machine in an upright disposition, or may even be inclined to reduce the overall height of the machine.
  • yarns run from bottom to top of the machine the tendency of the fumes to rise is assisted by the running yarns and it has been proposed to locate common fume extraction equipment adjacent the tops of the heaters for serving all heaters in a row.
  • FIG. 1 is a fragmentary front view of one end portion of a yarn heater assembly according to the invention.
  • FIG. 1a shows a modification of FIG. 1
  • FIG. 2 is an end view of the heater assembly of FIG. 1.
  • FIG. 1 two yarns 10 are indicated as running downwardly through an upright heater assembly indicated generally at A.
  • the yarns 10 are heated by running in lengthwise grooves 11 of a heater plate 12, and the chain-dot line 13 of FIG. 1 denotes the bottom end of that part of the heater assembly which is actually involved in heating the yarns, the heater plate 12 being located in an opensided channel-like lengthwise recess provided by a casing 14 which in generally well-known manner encloses heating means for the heater plate, such as electrical heating elements with insulation to limit heat loss (not shown), although other methods of heating could be employed.
  • heating means for the heater plate such as electrical heating elements with insulation to limit heat loss (not shown), although other methods of heating could be employed.
  • the casing 14 of the heater assembly is formed with an integral endwise extension 15 which has the same contours as the main casing 14 and which could be a separately formed part secured to the main casing instead of being integral therewith.
  • the endwise extension 15 forms a housing for fume removal means which is thereby incorporated as part of the heater assembly, the extension 15 being shaped to the same cross-sectional contour as the main casing 14 to provide an open-sided lengthwise recess 16 through which the yarns 10 travel, the recess housing a co-extensive box-like suction chamber 17 which is secured by its rear wall 18 to the rear wall 19 of the extension.
  • the suction chamber 17 is conveniently made from sheet metal by fabrication, its rear wall 18 and side walls being formed by bending a first sheet metal strip to channel shape, and its front wall 21 being provided by the base of a second sheet metal strip also bent to channel shape and having its side walls 22 secured as by welding to the inner faces of the side walls 20 of the first channel shape strip.
  • the second bent strip provides an open-ended channel through which the yarns 10 travel from the heater plate 12, but the ends of the suction chamber 17 are otherwise closed, the base of the channel for the yarns 10 being the front wall 21 of the box-like suction chamber thus fabricated.
  • the two yarns 10 run along the length of the suction chamber adjacent its front wall 21, which is provided with inlet means in the form of a lengthwise slot 23, through which fumes given off by the yarn are drawn into the suction chamber 17.
  • inlet means instead of a slot may be used, such as a row of holes or short slots 23a (see FIG. 1a).
  • the suction chamber 17 is connected to an exhaust pipe 24, preferably near the bottom end of the chamber, which is connected to a source of suction so that fumes and condensate are drawn from the chamber of disposal.
  • its front wall 21 can also be provided with a condensate drain hole 25(FIG. 1), through which is sucked for disposal any condensate which may form on the front wall 21 of the chamber and flow down the front wall. More than one such drain hole can be provided in the front wall 21.
  • the hole 25 seen in FIG. 1 is located on the right hand side of the front wall near its bottom end, and would be so located if the heater assembly shown upright were inclined to the right.
  • Near the drain hole 25 is shown a shallow ledge 26 for trapping any condensate flowing down the front wall 21. There could be further such ledges near further drain holes in the front wall 21.
  • a yarn heater assembly comprising means defining an elongate heating zone for at least one running yarn, the improvement comprising an endwise longitudinally projecting extension at one end at least of said assembly, and fume removal means incorporated in said extension.
  • a yarn heater assembly comprising means defining an elongate heating zone for at least one running yarn, the improvement comprising an endwise longitudinally projecting extension at one end at least of said assembly, said extension being formed to provide an open-sided lengthwise recess, a box-like suction chamber housed in said recess to be co-extensive therewith, a lengthwise front wall of said suction chamber adjacent which the running yarn travels, inlet means in said front wall through which fumes given off by the yarn are drawn into the suction chamber, and means for applying suction to said suction chamber.
  • Yarn heater assembly according to claim 2, and further comprising at least one condensate drain hole in said chamber front wall, and at least one condensate trapping ledge adjacent said drain hole.
