Definitions

  • the present invention relates to a method for pulling sawtooth wires on a roller to be equipped with a clothing for textile machines.
  • Rollers equipped with a saw tooth set are used in a wide variety of textile machines, e.g. in carding machines, in opening devices, impact devices, tearing devices, cleaning devices, etc.
  • the fiber material processed by these sawtooth rollers should be distributed as regularly as possible. This requires a random tip distribution of the sets.
  • this is not achieved by the known methods for applying the sawtooth wires to the rollers because the tip distribution is at least partially regular, so that lanes form between the tips, within which the fiber material is hardly or at least incompletely exposed to the tips. This fact has already been counteracted by pulling several sawtooth wires next to each other onto a respective roller. However, these methods did not lead to the desired success.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, achieves the object of providing a method for pulling on sawtooth wires on a roller, in which a temporary guide member is arranged on the roller at both ends, which is used to guide at least the first gear serves the winding running in an axial direction of the roller, each subsequent course being passed through the respective preceding course, and then the guide member is removed and the winding running in the opposite direction takes place, the first course of which is guided by the first course of the original winding becomes.
  • Figure 1 shows schematically a roller to be equipped with a set and a groove pierced therein
  • Figure 2 shows schematically the beginning of the application of a first sawtooth wire section
  • FIG. 3 shows schematically the application of the second sawtooth wire section
  • Figures 4 and 5 show different embodiments of sawtooth wires.
  • Figure 1 shows a smooth-walled roller 1, which is to be equipped with a set.
  • the axial length of the roller 1 depends on the respective later use.
  • the roller body can be solid or a hollow cylinder, ie a piece of pipe.
  • Shaft ends 8, 9 for the respective bearings are indicated on both sides.
  • a groove 7 is now inserted into the jacket of the roller at an area which has the same distance from both ends of the roller.
  • This groove 7 is sinusoidal and is self-contained. In the illustrated embodiment, only one groove 7 is indicated.
  • a plurality of grooves can also be arranged at a respective distance, or a single groove 7 can then be present, which, however, does not have the same distance from both ends of the roller 1.
  • a flat wire 2 is now inserted into this groove 7, see FIG. 2, and in places, e.g. locked by spot welding or by soldering in the groove 7.
  • a first sawtooth wire section 3 is placed against one side of the flat wire 2, connected to it at least in places and then wound around the roller 1.
  • This winding is now carried out on the right-hand section of the roller 1, the winding direction being indicated by the arrow 4.
  • the first course of the winding is led through the flat wire 2 and the subsequent courses, continuing to the right in the direction of arrow 4, through the respective previous course, winding in a known manner up to the edge wire (not shown). So that the right half of the roller 1 is completely wrapped.
  • the sinusoidal shape of the flat wire 2 now ensures that there is a random distribution of the wire tips, which results in an optimal tip distribution.
  • the flat wire 2 is now removed next to the first sawtooth wire 3, since it could otherwise form an empty space along the circumference of the roller 1.
  • the first sawtooth wire 3 For this purpose, for example, as shown in FIG. 3, it is ground down to the circumference of the roller 1.
  • the removal can obviously also be done in other ways.
  • the winding of the second sawtooth wire section 5 is started. Its first handling is guided by the first handling of the first sawtooth wire section 3, so that the sinusoidal shape is again present here.
  • the winding of the second sawtooth wire section 5 takes place in the direction of the arrow 6 (see FIG. 3), with each passage again being led through the preceding one and the winding being carried out up to the edge wire on the left.
  • the entire roller 1 is now equipped with the clothing continuous
  • sawtooth wires or their feet can be used, for example, these sawtooth wire sections can be used as shown in FIG. 3, linked or, as shown in FIG. 4, locked.
  • first sawtooth wire section 3 and a single sawtooth wire section 5 there is only a single first sawtooth wire section 3 and a single sawtooth wire section 5.
  • a plurality of first sawtooth wire sections 3 and a plurality of second sawtooth wire sections 5 are wound parallel to one another onto the respective roller section. Accordingly, only a respective section of a respective first sawtooth wire section would then be connected to a section of the flat wire 2, with successive courses of the individual sawtooth wire sections resting against the one of the plurality of parallel first sawtooth wire sections closest to it.
  • the plurality of second sawtooth wire sections would then also be connected to and guided by only one section of a first sawtooth wire 3, which previously previously touched the guide member 2 which has now been removed.
  • the further mutual guidance of the further gears of the plurality of second sawtooth wire sections 5 would then take place in accordance with the process described above when wrapping with the first sawtooth wire section 3.
  • the roller 1 would be wrapped in the region of the arrow 4 with a plurality of first sawtooth wire sections 3 and the side indicated by the arrow 6 with a plurality of second sawtooth wire sections 5, the respective gears running parallel to one another.
