Definitions

  • the invention relates to a device for multiple passage of at least one fiber cable through an oxidation furnace by means of godets, wherein the at least one fiber cable is deflected via at least one interleaved galette.
  • this conversion requires a period of about 60-90 minutes, during which time the fiber optic cables are expediently passed continuously through the oven or ovens with a defined voltage. In this case, it must be avoided that it comes to fiber clusters such as crossovers, knots or bundles of fiber cables, as this would make the controlled heat dissipation difficult.
  • the furnaces in production facilities have multiple passages, so that the cables can be parallel to each other and meandering through the respective furnace.
  • Pulleys are provided on the outside, because on the one hand temperature-resistant bearings are expensive and on the other hand, in a possible winding formation due to yarn breaks easy access by the plant operator is required.
  • pulleys are freely rotatable and are moved by the fiber cables.
  • the fiber cables are pulled by a train to the furnace, with a train in front of the furnace acting as a brake to build up the fiber tension required for the process.
  • a train in front of the furnace acting as a brake to build up the fiber tension required for the process.
  • this tension measuring rollers are usually provided before the following train, which then generate a signal to adjust the train speed. The voltage transmission or the compensation within the multiple furnace throughput takes place via the freely rotatable pulleys.
  • the GB 1280850 A shows an oxidation furnace in which the endless fibers are passed meandering. The deflection of the fibers via godets, which are arranged outside the furnace. Each galette has its own wave.
  • the US 3,552,923 shows an oxidation furnace in which the fibers are deflected via godets within the furnace.
  • Each galette has its own shaft, which are arranged at an angle to each other.
  • Object of the invention to enable a device for a multiple pass of a fiber cable through an oxidation furnace with a simultaneous voltage compensation.
  • the apparatus for multiple passage of at least one fiber cable through an oxidation furnace godets, wherein the at least one fiber cable is deflected via at least one interleaved galette.
  • the godet comprises a shaft on which at least two individual roles are attachable, each single roll is rotatably mounted on the shaft, a multiple pass through the oxidation furnace is possible, at the same time a voltage compensation of the fiber cable is achieved.
  • the fiber cables are no longer guided around the godets by means of friction, but by the rotatably arranged single role, reduce the tension in the fiber cable.
  • the fiber cables are deflected by a common rotatable galette, whereby a part of the fiber cables slides with friction on the godet, since the fiber cables have different distortions and stresses.
  • the voltages can be reduced by the fiber cable is guided and deflected at each deflection on a galette by a separate single role.
  • Each of these individual rollers may preferably have a rolling, ball or sliding bearing, not shown, for minimizing the frictional resistance.
  • each individual roll has a shoulder at least in the region of one end face. This ensures a leadership of the fiber cable on a single role.
  • An advantageous embodiment is that the single role in the region of the front side with the shoulder has a recess into which the end face of another single role can dip. This prevents the fiber cable between the single rollers can be trapped.
  • a further improvement can be achieved in that the end face, which dips into the recess, also has a shoulder. This also enhances the protection of the fiber cable against pinching in the gap between the single rollers.
  • a centering of the individual rollers to each other can be achieved in that the recess has a conical or concave contour.
  • the end face of the single roller which dips into the recess, a corresponding to the recess conical or convex contour.
  • shoulders which are preferably formed in different heights, the front side with the small shoulder in the recess on the front side with the large shoulder to dive, where there is a sleeve-shaped overlap, in which the fiber cable is not in can get into the gap between the single rollers.
  • a preferred embodiment is that the shafts are mounted in a holder, wherein the angular position of the shafts is adjustable via the holder.
  • the inclination angle and thus the deflection of the fiber cable can be adjusted by the oxidation furnace.
  • FIG. 1 the plan view of an oxidation furnace 1 with bilateral godets 2a, 2b and the fiber cable 3 running thereon is shown schematically.
  • the fiber cable 3 is supplied from the left coming from the oxidation furnace 1 and leaves after several passes the oxidation furnace 1 horizontally offset on the right side. However, it is also possible that the fiber cable 3 leaves the oxidation furnace 1 on the left side, if required by the process or the local conditions.
  • FIG. 2 shows once again a pair of godets 2a, 2b with a fiber cable 3.
  • Each godet 2a, 2b consists of at least two individual rollers 4a, 4b, which are attachable to shafts 5a and 5b.
  • five individual rollers 4a, 4b are mounted on a shaft 5a, 5b.
  • the shafts 5a, 5b are fixed in a two-sided holder, not shown, but can also be mounted only on one side.
  • the brackets are slidably disposed so that the angular position required for the desired offset is adjustable.
  • the upper yarn path where the fiber cable 3 runs from left to right is shown as a solid line
  • the lower yarn path where the fiber cable 3 runs from right to left is shown as a dashed line.
  • FIG. 3 The physical law for the displacement of the fiber cable 3 is in FIG. 3 shown.
  • a thread or a fiber cable 3 is always anxious, due to the transverse forces occurring, to run up perpendicular to a rotating roller or galette 2b at an angle of 90 °.
  • the actual kink in the fiber run arises during the running of the thread or fiber cable 3, when the frictional forces between the fiber cable 3 and the roller surface are no longer sufficient to apply resistance to the axial shear forces. Then the fiber cable 3 slips so far, until the previously running radially over the roller fiber cable 3 forms a straight line with a perpendicular angle to the opposite role.
  • the individual rollers 4 a, 4 b have a large shoulder 7 b in the region of a first end side and a small shoulder 7 a in the region of the second end side.
  • the single roller 4a, 4b has in the region of the first end face, on which the large shoulder 7b is arranged, a recess 8, into which the small shoulder 7a can dip. This avoids that the fiber cable 3 slips into the gap 6 between two individual rollers 4a and jammed there.
  • the large shoulder 7b thus covers the small shoulder 7a of the adjacent single roll 4a, 4b in the manner of a sleeve.
  • a self-centering is achieved by the second end face of the single roll 4a, 4b with the small shoulder 7a has a conical or convex contour.
  • the recess 8 is also conical or concave at the first end face with the large shoulder 7b.
  • the individual rollers 4a, 4b depending on the desired number of passes through the oxidation furnace 1 interchangeable and have a different width. It makes sense always to use individual rolls 4a, 4b with a width whose multiple corresponds to the total width of the oxidation furnace 1 or the width of a godet 2a, 2b.
