Definitions

  • the present invention relates to a singeing device for threads in the textile industry, according to which the thread to be singed is passed axially through a hollow electrically heated cylinder.
  • the invention is characterized primarily in that the electrically heated cylinder through which the thread to be singed is passed, forms an inner cylinder surrounded in radially spaced relationship thereto by an outer cylinder, and in that at least one intermediate cylinder is arranged in radially spaced relationship to said inner and outer cylinders and held in position by the end walls pertaining to said outer cylinder, each of said cylinders -being provided with a longitudinally arranged slot with all of the slots in alignment with each other so that the total passage formed by said slots extends from the outer cylinder into the inner cylinder and through the end walls thereof, said intermediate cylinder or cylinders having the inner ⁇ surface facing said inner cylinder ⁇ designed as reecting mirror service for reecting heat toward said inner cylinder.
  • the exit side of the inner cylinder communicates with conduit means adapted to be connected with a source of air under pressure.
  • the present invention relates to a singeing device for threads which comprises electrically heated hollow cylinders through which the vthread is moved in axial direction.
  • Singeing devices of this type are known and are employed in so-called yarn singeing machines in which the singeing is effected during a respooling or rewinding operation.
  • FIG. 1 diagrammatically illustrates a partial section through a singeing device according to the present invention, said section being taken along the line I-I of FIG. 2.
  • FIG. 2 illustrates a section taken along the line II-ll of FIG. 1.
  • FIG. 3 is a perspective view of the inner cylinder body employed with a singeing device according to the invention.
  • the present invention is based on a singeing device for threads which comprises an electrically heated hollow cylinder through which the thread is moved axially. This movement may be effected in such a way that the thread follows precisely the central axis of the hollow cylinder or, that the thread within the hollow cylinder carries out a slight balloon-shaped movement as a result of which the thread moves along the inner wall of the hollow cylinder so that it will get into contact directly with the heated mantle surface of the hollow cylinder.
  • the hollow cylinder comprises a plurality of individual cylinders which have one longitudinal slot and in radially spaced relationship extend one around the other.
  • the outer cylinder is on both sides provided with a likewise slotted annular end wall. Between the said walls .the individual cylinders are held of which on the inner cylinder there is mounted the heating wire which consists of high heat resistant material of any suitable type.
  • At least one further cylinder between the inner cylinder and the outer cylinder comprises a mirror surface adapted to reflect the heat rays inwardly.
  • An annular passage leads into the exit side of the inner cylinder in a direction counter to the direct-ion of movement of the thread, said annular passage being connectable to a conduit.
  • the singeing device illustrated therein comprises an outer cylinder 1 with a longitudinal slot and wit-h an end wall 2 which is slotted up to the central passage, said end wall 2 forming one piece with the outer cylinder 1.
  • a further end wall 3 which similar .to the end wall 2 has a slot extending to the central passage 4 is inserted into the outer cylinder 1.
  • the outer cylinder 1 and the end walls 2 and 3 may be made of metal, such as aluminum, brass, or the like.
  • the inner cylinder 6 of a high heat resistant material, as for instance ceramic material, which by means of its end has its location properly determined on the end walls 2 and 3.
  • FIG. 3 also shows the ribs 8 which are offset with regard to each other and extend in the longitudinal direction and on the outer surface of the inner cylinder 6.
  • the ribs 8 serve for locating the heating Wire 9 which is passed around the ribs 8 in loops and the ends of which are in conformity with FIG. 1 passed from the outer cylinder 1 and are adapted by means of the contact elements 10 to be connected to a network.
  • the two further cylinders 11 and 12 which each comprise mirror surfaces for reflecting the heat rays inwardly.
  • the end walls 2 and 3 are provided with annular grooves 13 and 14.
  • the cylinders 11 and 12 are similar to the inner cylinder 6 and the outer cylinder 1 provided with a longitudinal slot. As will be evident from FIG. 2, on the inner cylinder 11 at both sides of the slot 7, bent strips 15 extend radially outwardly and have the bent portion 16 located outwardly on the cylinder 1.
  • the further cylinder 12 has its longitudinal edges engage the outside of strips 15.
  • the heating wire 9 When the heating wire 9 is heated by introducing current thereinto, the heat is conveyed to the inner cylinder 6 which in its turn conveys the heat centrally inwardly into the passage formed by the cylinder 6.
  • the radially outwardly conveyed heat is by means of lthe cylinder 11 forming a heat ray reflecting mirror surface reflected radially inwardly and thus aids in the further heating of the inner cylinder ⁇ 6.
  • the cylinder 1 is provided with yan extension 18.
  • the space surrounded there-by is covered by a hood 19.
  • a conduit 20 extends radially from the outside into the space confined by the hood 19.
  • the conduit 20 may be connected for instance to an air circuit.
  • hood 19 is provided with an extension 21 which together with the funnel wall 22 at the end wall 2 forms an -annular passage 23 which latter in a direction counter to the direction of movement of the thread leads into the inner cylinder 6 so that air passing through the conduit 20 into the air chamber of the hood 19 will in a direction counter to the direction of movement of the thread pass through said annular passage 23 into the cylinder 6 whereby the singeing operation is aided considerably and burned residues are blown out of the cylinder 6, and the air acts counter to the upwardly owing off gases. This results in damming up the heat within the inner cylinder ⁇ 6.
  • the insertion of the thread to be singed in the singeing device is effected in a manner known per se radially from the outside through the slot 7 into the interior of the cylinder 6 so that a special ⁇ threading operation becomes superfluous.
  • the slot 7 furthermore offers the possibility in case the thread is at a standstill, for instance as a result of a thread break, of temporarily removing the thread from the singeing device radially outwardly and to knot it together outside the singeing device so that the thread will 'be located inside the singeing device only when the thread is in movement and is subjected to the singeing oper-ation only during its movement.
  • a singeing device for threads which includes: yan inner hollow cylinder consisting of high heat resistant material and defining a passage in axial direction thereof for the thread to be singed, electric heating wire means on the outer surface of said cylinder, an outer cylinder having its mantle surrounding said inner cylinder in radially spaced relationship thereto and being provided with end walls extending to the end portions of the mantle of said inner cylinder, and intermediate cylinder means interposed between and in radially spaced relationship to said inner and outer cylinders while being held in position by said end walls of said outer cylinder, each of said cylinders and cylinder means being provided with a longitudinally arranged slot with all of said slots in alignment with each other so :that the total passage formed by said slots extends from the mantle of the outer cylinder into the axial passage of said inner cylinder and ⁇ through the end walls of said outer cylinder, said intermediate cylinder means having the inner surface thereof facing said inner cylinder and designed as reecting mirror surface for relie
  • a singeing device in which said inner cylinder has a thread inlet and a thread outlet, and conduit means communicating with said thread outlet and adapted to be connected with a source of air under pressure.
  • a singeing device in which the outer mantle surface of said inner cylinder is provided with outwardly extending protrusions, and in which said heating wire means is held in position by said protrusions.
