Definitions

  • the invention relates to a device for spreading a fiber bundle and a related method.
  • the apparatus comprises a so-called tension buildup unit consisting of a series of statically arranged round bars and a stress reduction unit consisting of a series of driven rollers, the static bars and the driven rollers being arranged perpendicular to the direction of the passing fiber bundle forms a wrapping contact with the surface of the row of static bars and driven rollers.
  • the driven rollers are operated at a higher differential speed with respect to the speed of the running fiber bundle, whereby a spreading effect of the fiber bundle is achieved.
  • the fiber bundles first make a direct sheathing contact with the surface of the static rods to subsequently make a direct sheathing contact with the series of driven rollers.
  • the driven rollers are operated at a peripheral surface speed which is at least three times the speed of the moving fiber bundle. This speed difference controls the tension of the fiber bundle.
  • Strangbahnen are textile materials in which the individual threads are distributed in a continuous yarn path, just the strand web, evenly in the transverse direction.
  • This treatment of the strand web corresponds to the actual spreading.
  • the strand web is moved forward under a tension, which, however, is small enough so that the threads do not break.
  • the strand webs are passed over rollers and a plurality of grooved, combined and rotatably driven units such that the strand web is separated by the webs located between the grooves and thus displaced in the transverse direction, wherein a smoothing of Strangbahn takes place by the strand web is again guided by redirecting them after their division via fixed rods.
  • a disadvantage of this method is that lane formation is not avoided in spread strand webs, especially not if lower basis weights are to be sought. The tendency to form a lane is greater, the greater the spread and thus the lower the weight per unit area of the spread fiber bundle.
  • the known spreading device has a convexly curved Sp Drownde, which imparts a direction component perpendicular to the longitudinal extent of the fiber filament bundle to the guided over the Sp Dahl tile to be spread fiber filament bundle.
  • the fiber filament bundle can be placed on the convexly bent spreading edge under tension and then moved away again with at least one direction component vertically from the filament fiber bundle.
  • This known device is now characterized in that rotary shafts with convexly bent rods are combined in one device such that the convexly curved rods serving as wings interlock with one another by the rotationally driven rotary shafts in such a way that fiber filament bundles introduced under tension into the spreading device join with each other between the edge regions changing clamping force can be clamped. Due to the changing clamping force is to be achieved that the filaments gradually shift in the width direction, so that when leaving the spreading a splayed tape is present.
  • the disadvantage of such devices is that low basis weights are hardly achievable if lane formation is to be avoided.
  • EP 1 172 191 B1 a production apparatus and a production method for opened fiber bundles and a prepreg production method are known.
  • the spreading device has two rollers held in contact with a traveling fiber bundle and a base body which reciprocates to be repeatedly and periodically repeatedly brought into contact with and taken away from the traveling fiber bundle.
  • the arrangement is now designed such that the running fiber bundle between the rollers receives no pressure when it is not in contact with the rollers.
  • the peripheral surface speed of at least one of the rolls is kept lower than the running speed of the running fiber bundle.
  • the base body is pivoted back and forth with an oscillation frequency and a defined amplitude so that the fiber bundle is applied to the rollers.
  • the object of the present invention to provide an apparatus and a method for spreading a fiber bundle, by means of which a high quality and uniformity of the spread-out fiber bundle, while achieving extremely low basis weight, and a high production speed can be achieved.
  • the device for spreading a fiber bundle generally has a fiber bundle stock, from which the fiber bundle to be spread is conveyed and can be supplied to a fiber consumption via a resistor and at least one first pulse drive cooperating with the resistor.
  • the fiber bundle supply is wound up on a spool, from which the fiber bundle can be fed after passing through the actual spreader spreading device, the fiber consumption being either a take-up roller that is wide in accordance with the spreading or a direct segmented tray on a multiaxial cover, for example.
  • the fiber consumption is in any case constructed so that it is able to exert a corresponding withdrawal tension on the finished spread fiber bundle.
  • an additional speed component in its conveying direction and an additional speed component counter to the conveying direction during spreading are now impressed alternately by means of the pulse drive in predetermined frequencies to the fiber bundle.
  • an additional velocity component in predetermined sequences can be imposed on the fiber bundle only in the conveying direction of the fiber bundle or in predeterminable sequences only counter to the conveying direction of the fiber bundle during spreading.
  • a significant advantage of the device according to the invention is that all expandable materials including steel can be spread with high quality and off-gauge to very low basis weights.
  • Another significant advantage is that between the fiber bundle supply and the first resistor already a very large spread can take place when the fiber bundle supply is preferably already designed as an additional pulse drive. This can be achieved at or after the first resistance degrees of expansion of 25 ° to 30 °, which corresponds to 8 to 10 times, which is feasible in conventional devices with normal spreading.
  • the extremely great advantage of the device according to the invention is clear, and therein is also a significant cause that very high degrees of expansion and thus very low basis weights can be achieved, which are not even approachable with devices according to the prior art.
  • the predefinable sequences of the additional speed components are variable by means of a control device for the pulse drive with respect to their frequencies and / or amplitudes to achieve a predeterminable basis weight.
  • the control device controls the pulse drives in accordance with the material to be spread and the surface weight to be achieved be in terms of their frequencies and their amplitudes or in terms of their frequencies or their amplitudes. This results in an extremely high flexibility of the device with regard to the desired spreading result to be achieved different materials of the fiber bundles to be spread.
  • this has at least one spreader bar which is transversely deflected relative to the conveying direction of the fiber bundle and over which the fiber bundle can be guided with a defined wrap angle.
  • the defined wrap angle is formed in accordance with the transverse offset of the spreader bar to the plane spanned by the spread fiber bundle conveyor plane.
  • the resistor may also be a blowing or suction device, may be formed as a clamping device of a mechanical or electromagnetic type or as an electromagnetic fiber bundle deflection device.
  • the decisive factor is that, according to the invention, the resistance is exerted on the spread fiber bundle passing through the spreading device such that the individual filaments of the fiber bundle are forced to arrange themselves more and more adjacent to one another so that a spreading of the fiber bundle withdrawn or conveyed away from the fiber bundle supply takes place.
  • the fiber bundle supply is arranged on a non-rotating spool and is removable from this.
  • the coil is arranged in the conveying direction of the fiber bundle before the resistor, after which the first pulse drive is arranged. This order ensures that the fiber bundle is pulled off via the resistor against the braking effect of the coil, so that the fiber bundle is always impressed a voltage.
  • the throughput speed of the fiber bundle supply by the device according to the invention is impressed by the pulse drive in addition a corresponding speed component, which is impressed substantially in the direction of the plane formed by the spreader when passing through the conveyor, in the direction of the passage of the fiber bundle or against the direction of the fiber bundle by the spreading device.
  • the non-rotating spool is preferably designed as a driven spool, which in particular is a spool driven in predeterminable sequences in the direction of rotation in the manner of a second impulse drive.
  • the predeterminable sequences of the velocity components of this second pulse drive are out of phase with those of the first pulse drive.
  • the resistor is arranged downstream of the first pulse drive. In such a case, preferably only the first pulse drive is provided for the spreading device.
  • the device is preferably designed such that the spread fiber bundle is received on a load arranged downstream of the resistor and configured as a winder.
  • the device therefore basically consists of fiber bundle stock, first pulse drive, resistor and consumer, for example in the form of a winder. It is preferably also possible and conceivable that the fiber bundle supply is designed in particular in the form of a driven coil as the first impulse drive.
  • the winder is driven at a constant winding speed.
  • the constant winding speed is to ensure that during the spreading the fiber bundle is subjected to a tensile force.
  • the tensile force may preferably have such a size that even with directed against the direction of passage of the spread fiber bundle in the sense of a negative velocity component additional velocity component, the resulting speed from the flow rate of the fiber bundle and against the direction of passage directed additional velocity component is positive.
  • the additional speed component it is also possible for the additional speed component to have a size such that, at least for a short time, the resulting speed from the passage speed of the fiber bundle and additional speed component directed counter to the passage direction is zero.
  • the winder of the device is preferably designed to be driven in the manner of a second, additional impulse drive whose predefinable sequences of the speed components are out of phase with those of the first impulse drive.
  • the predeterminable sequences of the velocity components which are impressed on the fiber bundle as it passes through the device during the spreading process, so to speak, cross the fiber bundle by means of such a coil driven in predeterminable sequences in the direction of rotation in the manner of a second impulse drive, whereby the individual filaments in their Endeavor to arrange themselves next to each other should be supported.
  • the pulse drive according to the invention or the device with such pulse drives can be achieved that a nearly ideal spread is achieved, in which the desired extremely low basis weights can be achieved and in which, so to speak, ideally the spreading takes place in such a way that no lane formation occurs at all, but filament is arranged next to filament. It is, however, in principle also possible to drive the spreading so far that the individual filaments are even arranged at a certain distance from each other. Such layers to be produced later in multiaxial layers may make sense depending on the application. The basis weights of such layers may be even lower than previously stated.
  • the resistor is followed by an additional, second impulse drive, which is not the winder, which nevertheless is like the principal mode of operation of the impulse drives , namely vorgebare sequences of the velocity component phase-shifted generated to those of the first pulse drive.
  • the control in the presence of a first impulse drive and a second, additional impulse drive, the control can now be made so that either the first or the second additional impulse drive operates as a pulse drive and the non-fiber sequences predeterminable sequences of velocity components during the spreading impelling impulse so to speak is neutralized.
  • Neutralization is understood here to mean that the predefinable sequences of the velocity components in the non-effective pulse drive are not impressed on the fiber bundle, but that the fiber bundle passes through the pulse drive only without such an effect.
  • the method for spreading a fiber bundle according to the invention at defined conveying speeds comprises a first step according to the invention, in which the conveying speed of the fiber bundle during the Spreading a pulsating velocity component is impressed.
