  • the invention consists in the novel steps, combinations and improvements herein shown and described.
  • An object of my invention is to provide a novel process for orientating filaments in a safe, simple, efiicient and inexpensive manner.
  • Another object of my invention is to provide a novel process and apparatus for orientating filaments with low breakage of filaments.
  • Fig. 1 is a front elevation partly in section away of one embodiment of my invention.
  • Fig. 2 is a rear sectional view taken along the line 22 of Fig. 3.
  • Fig. 3 is a side view as taken along the line 3-3 of Fig. 2.
  • Fig. 4 is a plan section taken along line 4-4 of Fig. 3.
  • Fig. 5 is a schematic rear view of the heating arrangement of the present invention.
  • resinous monofilaments as illustrated by polystyrene monofilaments, were oriented or stretched by extrusion into liquid ethylene glycol, glycerinc or concentrated CaCl solution bath at a temperature of approximately 210 to 240 F. From the first bath, the polystyrene was carried into a hotter second bath in the range of 230 to 300 F. where stretching or orientation to the extent of 300-1000% took place. The filament then was passed through water baths to remove the heating solution.
  • the filaments from an extrusion die are brought to their orientation temperature by contacting said filament with a heated moving surface and applying a tensioning force to said filaments while at their orientation temperature. More specifically, the filaments are contacted with and conveyed by at least one and preferably a plurality of heated rollers enclosed in a leak-proof hood member, the natural surface friction of the unoriented filaments preventing slippage at the temperatures involved.
  • the filaments have been drawings, referred to herein and illustrate one form of the serve to and broken atent mounted on shaft 38a, to rotate.
  • the means for indirectly adjusting the filaments to the desired orientation temperature comprises a vertical stack of heated rollers enclosed in a leak-proof housing.
  • This housing may preferably be insulated and provided with a chromium plated or aluminum external surface to minimize radiant heat loss.
  • Three sides of the housing are vertically adjustable by means of a counterweight construction with the back portion of said housing being fixedly secured to a supporting frame to insure a leak-proof construction.
  • the drive shafts of each of the motor-driven rolls extend through the fixed back of said shafts having a floating brass sleeve which fits snugly around the shaft to accommodate different positions of the shaft.
  • Heated rollers 3-11 and rollers 15 and 14 are driven by means of a motor 20 in combination with a conventional variable speed pulley arrangement and multiple chain and sprocket drive.
  • the operation of the roller driving means is as follows. Connected to motor shaft 21 of motor 20 is a variabie speed V pulley 22 (Fig. 1) which drives pulley 24 by means of connecting belt 23. Handwheel 25 is provided to adjust the motor supporting plates which in turn adjust the angle of V pulley 22 which controls the speed of the pulley, as is well known to those skilled in the field, such a construction being conventional.
  • Fixedly mounted on shaft 26 of pulley 24 is a sprocket 27 which drives sprocket 29 through chain 28.
  • Mounted on shaft 30 of sprocket 29 is sprocket 31 and roller 15.
  • roller 15 rotates, as does sprocket 31, which in turn drives sprocket 33 through chain 32.
  • sprocket 35 On the rotation of sprocket 35, sprocket 37 is rotated by means of chain 36, which in turn causes sprocket 38, A continuous chain 39 is driven by sprocket 38 which causes sprockets 4047 to rotate.
  • rollers 11 to 3, respectively, connected to the shafts 38a, 40a to 47a of sprockets 38 and 40 to 47 will also rotate.
  • the chain 39 on passing around sprockets 38 and 40 to 47 continues its path around idler sprockets 48, 49, 50 and 51 to complete a continuous circuit.
  • a housing member comprising integrally connected front 52 and sides 53 and 54 and separate back 55 is provided.
  • Front 52 and sides 53 and 54 are vertically adjustable by means of a counterweight 56 enclosed in casing 57, said counterweight belng attached to one end of rope 58 passing over pulleys 59 and 60 with the other end of said rope 58 being con-- nected to a plate 61 having attached thereto two smallv 3 ropes 62 and 63, each having a bracket 64 and 65 attached to its outer end, said brackets 64 and 65 being connected to sides 53 and 54 respectively.
  • sides 53 and 54 are provided with inwardly turned lips 80 and 81-, respectively, which are adapted to slide between the spaces provided by vertical strips 82, 83, 84 and 85, respectively.
  • Strips 82, 83, 84 and 85, as well as back 55, are connected to frame member 86 by means of bolts 87, 88 respectively, strips 83 and 85 being spaced from said frame by collars 89 and 90.
  • each of the shafts as illustrated by shaft 42 a, has mounted thereon a floating brass bushing or washer 92 which fits snugly between back 55 and plate 91 to accommodate different positions of the shaft.
  • Each of the shafts passes through a ball bearing unit as illustrated by unit 93 mounted in bearing 94 connected to framemember 95.
  • V a I a Steam passing through rotary steam joints 96 to 104 (Fig. 5) is transmitted to rollers 11-3, respectively, by means of pipes 105-113, as illustrated by pipe 108 (Fig.
  • Steam is fed to the pipes 105-113 by passing through common inlet pipe 133 through pipe 134 with portions of said steam being taken off through pipes 113 and 135, said pipes 134, 135 and 113 being respectively provided with valves 136-138, strainers 139-141 and reducing valves discharged from pipe 134 to pipes 105-109; while steam is discharged directly from pipe 135 to pipes 110-112 and directly to pipe 113.
  • the mode of operation of the above described embodi ment is as follows.
  • the housing is in its down position as shown in Fig. 2 and by manipulating the heating arrangement rollers 3-11 are brought to the desired temperatures, depending upon the type of resin that is to be oriented.

  • rollers After the rollers have been adjusted to the desired temperatures, motor is turned on whereby an insig- F.,. preferably 220-240 240-330 F., preferably nificant first portion of the filaments, which is inferior and unsuitable for orientation, is carried by the rolle'rs3-11, 12, 14 and 15 to guides 16 and 17 Where it is threaded; this threading phase requiring only a few seconds.
  • an insig- F. preferably 220-240 240-330 F., preferably nificant first portion of the filaments, which is inferior and unsuitable for orientation
  • the number of rollers used in accordance with my invention will vary depending upon the surface contact that is needed for the particular monofilament that is being oriented. For a needed surface contact the number of rollers that may be used may be accordingly decreased by using rollers of larger diameter to give an equivalent surface contact length, as will be well understood by those skilled in the field.
  • the structure of the housing member may be modified andstill be within the spirit of my invention. For example, in place of the housing member as shown in my illustrated embodiment, a housing member may be used wherein only the front fact of the enclosure slides up down with the back panel, sides and top being stationary.
