  • the invention is therefore based on a train for the transport of filaments, in particular carbon filaments, consisting of a number of driven rollers around which the filaments are guided, wherein one of the rollers cooperates with an employee counter-roller and the filaments run through the nip formed in this way.
  • the filaments are endless fibers. A strand or a bundle of filaments forms a cable.
  • Object of the present invention is to improve a generic device.
  • the rollers and their drive are accommodated in a transportable frame unit, wherein a guide is provided in the axial direction of the respective roller and parallel thereto for a cutting device designed as a knife, wherein the guide is designed such that the Cutting device by means of the guide to the roll surface of the roll feasible and in the axial direction along the roll surface of the roll is feasible.
  • a guide is provided in the axial direction of the respective roller and parallel thereto for a cutting device designed as a knife, wherein the guide is designed such that the Cutting device by means of the guide to the roll surface of the roll feasible and in the axial direction along the roll surface of the roll is feasible.
  • the driven rollers are driven according to a preferred embodiment of the invention by a drive via a traction means (chain).
  • the drive further includes the electrical control and the power supply, so that the train of the invention after the mechanical installation only needs to be connected to the network and connected to the control of the fiber line.
  • the preferably mounted on top of the frame drive does not hinder accessibility to the individual rollers of the train.
  • the driven rollers can each be assigned a single motor, so that the rollers can be driven separately from each other. Also, in this case, the individual motors can be controlled separately. The motors can be controlled, for example, by controlling the torques of the respective motors.
  • the non-driven rollers of the inlet and / or outlet are preferably arranged in height adjustable on the frame, so that the height of the cable run can be adjusted. This is particularly advantageous when the train according to the invention is upstream or downstream of a furnace and the filaments combined into cables are in particular carbon filaments. Such devices usually have very narrow input gaps for the cables to be treated, by the adjustability of the cable run can be made to adapt to the particular circumstances.
  • a further embodiment of the invention provides that the non-driven input and / or output roller is coupled to a measuring system for detecting the tension present in the incoming or outgoing cable. This is done for example by a load cell, which is mounted between the frame and the storage of the respective roller.
  • a measuring system designed in this way, the force exerted by the cable on the roller and taking into account the directions of movement, the tensile force prevailing in the cable can be determined.
  • At least one of the driven pull rolls is at least partially connected, that is to say provided with a cover surrounding the roll surface at least in a partial circumferential region.
  • a draw roller is a roller of the train.
  • the cup-shaped covers serve to protect people and prevent hazards due to incoming column, especially in the area between the running on a draw roller cable and the corresponding rotating roller surface.
  • the cover is preferably associated in the partial circumference of the roller surface of the tension roller, around which the filaments bundled in cables are not wound in normal operation.
  • normal operation means that there is no Filamentriss.
  • the torn-off filaments wrap around the roll (s) and, in this case, also the partial circumference of the roll surface of the roll is wrapped with the cables in which the cover is arranged.
  • the cutting device is, for example, a knife attached to an extension, which is pulled by the operator along the guide over the roll surface of the roll. In this case, the cutting device is moved manually. Alternatively, however, the cutting device can also be actuated automatically.
  • a drive for example an electrically driven drive, may be provided, which moves a cutting device, eg a knife, with the aid of the guide to the roller surface and / or preferably moves it in the axial direction along the roller surface.
  • the electric drive can be actuated for example by an operator as soon as the operator determines that it has come to a winding.

  • the middle of the tension rollers Z2 cooperates with a counter roller GW, which is adjustably mounted at its two ends and is adjustable relative to the tension roller Z2.
  • the adjustment of the counter roll GW to the tension roller Z2 is done motor or pneumatically by one associated drive GA1, GA2, which act on the bearings of the counter roll GW and thus enables an exact parallel position of the rollers GW, Z2.
  • FIG. 2 shows the arrangement of the rollers EW, Z1, Z2, Z3, GE, AW; the conveying direction of the filaments F is indicated by the arrows. This also applies to the other figures.
  • the incoming on the top of the inlet roller EW filaments F are deflected by the inlet roller EW down and run around the first, lying below draw roller Z1. From there, the filaments F bundled into cables run to the above lying draw roller Z2 and through the gap formed with the counter roll GW.
  • the filaments F bundled into cables now run down again to the third drawing roller Z3 and then to the outlet roller AW located at the same height as the inlet roller EW. About this exit roller AW leave the bundled to cables filaments F the train again.
  • the wrapping of the inlet and outlet rollers EW, AW through the filaments F bundled into cables is less than 90 °.
  • the looping of the draw rolls Z1, Z2, Z3 through the filaments F bundled into cables is essentially 180 °. This results in a good transmission of the drive torque of the rollers Z1, Z2, Z3 on the bundled filaments F.
  • FIG. 1 and 2 is the arrangement of the rollers EW, Z1, Z2, Z3, AW symmetrical to each other, resulting in a high variability in setting up the train within a fiber strand.
