Definitions

  • This invention relates to a method and apparatus for crimping a filament tow or fiber tow having a total denier of at least 5,000.
  • an object of this invention is to provide a method for placing the filaments or fibers of a tow of 5,000 denier or more into parallel alignment to insure uniformity and eveness of crimp of the tow in a crimping housing.
  • the present invention feeds the tow to be crimped through means that simultaneously exert transverse forces on the tow to align the individual elements of the tow prior to their entry into the crimping housing. This may be accomplished according to the preferred apparatus of the invention by feeding the tow between one or more groups of intermeshing gear wheels, the midregion of the teeth of said wheels being at a lower height than the teeth edges. This may be explained by reference to the accompany figures.
  • FIG. 1 is an elevational view of an apparatus for the stuffer box crimping ofa tow.
  • FIG. 2 shows. in section. part of the gear wheels on an enlarged scale.
  • FIG. 3 is a sectional view along the line III III in FIG. 2.
  • FIG. 4 shows a different embodiment of the combination of gear wheels.
  • an endless tow I which may be composed of a plurality of bundles, is passed between three successive pairs of intermeshing gear wheels 2, 3 and 4.
  • the teeth 5 are ofa reduced height 6, while the teeth at the sides, or end faces, of the wheels are of normal height 7.
  • the tips of the teeth of height 6 extend only to approximately the circumference of the pitch circle with the radius 8.
  • the teeth 5 repeatedly apply transverse forces to the thickest portions of the tow l lying in the approximately trapezoidal-shaped recesses of the teeth (see FIG. 3).
  • these sides form toothed flanges that enclose the tow 1 from the sides.
  • the stuffing rolls 9 may be in the form of smooth cylindrical rolls of approximately mm in diameter. These rolls are forced towards each other by spring action, as they feed the tow 1 against a wad of stuffed tow already present in the stuffer box I0.
  • a hinged door 11 At the outlet of the stuffer box 10 is a hinged door 11, which is loaded by a weight 12 in order to obtain the desired buckling pressure.
  • FIG. 4 shows a modified arrangement of the gear wheels.
  • the tow I travels over a guiding roller 13 to a central gear wheel 14 of relatively large diameter.
  • Gear wheel 14 meshes with three relatively smaller gear wheels l5, l6, and 17; these three wheels being spaced some distance apart on the periphery of wheel 14. It is not necessary that the peripheral wheels be smaller than the central wheel, however.
  • the teeth of the gear wheels 14, 15, I6 and 17 may have trapezoidal recesses similar to those provided in the teeth of gear wheels 2, 3, and 4 of FIGS. 1, 2, and 3. After the tow has passed the gear wheel 17, it travels to the rolls of a stuffing box crimper similar to FIG. 1.
  • the cross-section of the recess in the teeth of each successive group may be varied progressively from a circular cross section, for instance, down to the final preferred trapezoidal shape before being fed to a stuffer crimper device. This can be especially advantageous in forming a tow of the larger total deniers.
  • Apparatus for stuffer box crimping a filament tow of at least 5,000 total denier comprising:
  • a crimping chamber for receiving the parallel filaments and imparting a crimp to-the tow
  • stuffer rollers for feeding the tow from the alignment zone to the crimping chamber.
