Definitions

  • the chamber-blow box assembly is generally designated by numeral 12 and is comprised of sideleg-likemembers 27-and 28 project in parallel relation from the; bottom or -lower end of the assembly 12.
  • the assem bly lz is'rotated clockwise from the broken to the full line positionsof Figure 1 it moves up slightly into of a spinneret and for spinning in, the lack of a seal between the side walls and the perforated wall results in air leakage which deleteriously affects the properties of the spun threads.
  • Figure l is a view partially in elevation and partially in section showing in full lines the spinning chamber and blow box of the present invention in the position assumed during normal spinning operations and, in broken lines, the position which the box assumes when access to the spinning plate is required, as in spinning in;
  • Figure 2 is a view in section taken on the line 2-2 of Figure 1;
  • Figure 3 is a view similar to Figure 2 but showing an internal modification of the spinning chamber.
  • the numeral 10 designates the spinning assembly from which the melt is extruded (see arrow) in known manner through centrally disposed orifices in a spinning plate walls 13 and 14 interconnected by-an integral wall 15 atone end audterminatingin flanges 16" and 17 at the respective other .ends.
  • Extending between side walls13 andl14 are three perforated plates 18, 19 and 20 which are hermeticallysealed at their margins to the side Walls 13, and 14.
  • -The.plates 18, 19 and 20 subdivide the assembly -12 into a spinning chamber 21 and blow box 22.
  • the blow box isv supplied with air through a con-' duit 23'havingtherein a damper type valve 24.
  • the conduit 23 connects to'a bottom plate 25 constitutinga part of the, blow box 12.
  • the spinning chamber 21 and blow box 22 are defined to some extent by common parts and that the assembly 12 is a rigid self-sustaining structure completely free of leakage. Thus the path of air flow from the blow box 22 into and through the spinning chamber is accurately controlled.
  • the assembly 12 by bodily rotating the assembly 12 to the broken line position of Figure 1, easy access is had to the spinning plate or plates as may be required during spinning in.
  • the three screens or perforate plates 18, 19 and 20 serve accurately to orient cooling air flow for movement transversely of the chamber 21 and out of the open back of that chamber.
  • the threads leaving the chamber 21 pass through the well 26 to collection, not shown.
  • baflies extending parallel to the side walls of the chamber may be used.
  • a typical arrangement of these is shown in Figure 3.
  • the baflies are designated by numerals 31, 32 and 33. Since the structure depicted in Figure 3 is otherwise the same as that shown in Figure 2, like numerals are used to designate like parts.
  • a single assembly 12 can serve four spinning positions, one in each of the compartments into which the chamber 21 is divided by the partitions 31, 32 and 33. These four positions are disposed along a radial line of spinneret 11, which line extends normal to the plane of the paper as viewed in Figure 1.
  • the baffles prevent the separate threads from creating mutually interfering turbulence.
  • the assembly .12 Upon spinning in, the assembly .12 is tilted about pivot 29 from the full line position of Figure 1 to the dotted line'position, which provides unobstructed access to the spinning assembly 10 for installation or cleaning of a spinneret 11, for temporary collection of unsatisfactory portions of freshly extruded filaments in a manner known to the art, and for eventual threading in of the filaments.
  • the assembly 12 7 2,947,029 Patented Aug. 2; 1960 1 is pivoted to the full line position where it may be locked by latch means (not shown).
  • a melt spinning apparatus comprising'an-extrus'ionassembly having a spinning plate for -'extruding"a plu-' rality of threads in adjacent parallel patlisfa-pair of side walls and an integral back wall defining an elongated chamber, at least one perforated plate hermetically sealed at the edges thereof to said side Walls and through which ⁇ a gaseous medium is supplied to cool saidlthreads, the elongated chamber being disposed coaxially beneath said spinning plate and movable both axially-and'radially withrespect thereto from an operative position wherein the upper edge of said chamber is urged in sealed relationship against said extrusion assembly and said walls sur round the thread path to an inoperative unsealed position wherein the upper edge of said chamber is spaced axially and radially from said extrusion assembly and said walls are displaced laterally with respect to said thread path, a leg attached to and depending from the lower edge of each sidewall of said elongated chamber, said legs being disposed on
