Definitions
- the invention relates to a method for manufacturing an optical fiber ribbon having a plurality of parallel op ⁇ tables single fibers, wherein the surface of the individual fibers abschittrise is treated such that the Biegungsabphasen- dependence of the optical attenuation in the treated sections increases.
- the object of the invention is to provide a method for producing an optical fiber ribbon having a plurality of cut from ⁇ treated as individual optical fibers with a comparatively high degree of reproducibility of the required optical performance can be achieved in the fiber ribbon.
- This object is he ⁇ solved with the above-mentioned method invention according to the fact that the fiber ribbon is produced continu ⁇ ously, whereby the individual fibers at least torsion performed between the step of surface treatment and a subsequent process step of merging the purpose of producing the fiber ribbon ⁇ the.
- the torsion-free guidance ensures that a rotation of the treated section on the way of this section from the surface treatment step to the subsequent method step of bringing the individual fibers together in its angular position is not changed. It is therefore possible to combine the individual fibers with a predictable angular position of the surface-treated sections, whereby the bending dependence of the optical behavior of the fiber ribbon can also be accurately predicted.
- ⁇ through can be advantageously the fiber ribbon produced, for example, as a sensor bands with exactly predictable op ⁇ -Nazi properties use.
- a deflection of the individual fibers in the torsion-free guidance by bending the individual fibers takes place.
- a torsion-free guidance is nevertheless advantageously made possible, since the introduction of a bending stress into the individual optical fibers does not produce any torsional stresses in the individual fibers and thus ensures the torsion-free guidance of the individual fibers. If, due to the spatial requirements of the method, guidance of the individual optical fibers is required such that guidance of the respective individual fibers in a plane is not possible, the guidance can be achieved successively in two different planes by bending the individual fibers.
- a particular embodiment of the invention provides that the bending of the individual fibers takes place by deflection rollers over which the individual fibers are guided.
- the use of pulleys has the advantage that in this way a Verbie ⁇ tion of individual fibers with a constant bending radius can be particularly easy to perform.
- the diameter of the pulley ensures at the same time that a certain bending radius of the individual fibers can not be undershot, so that at the same time protection against excessive bending is ensured.
- At least one deflection roller is profiled at the periphery such that the Aufla ⁇ ge specifications the guided on the guide roller individual fibers is increased.
- the profile on the circumference of the deflection roller is adapted to the cross section of the individual fibers to be guided, ie, so to speak, depicts the negative shape of the cross section.
- the profile on the circumference of the deflection rollers can be obtained integrity in addition, for example, by a gummingmaschinenbe ⁇ which additionally complicates slippage of the Einzelfa ⁇ fibers.
- the axes of rotation of the deflection rollers are aligned at least substantially parallel to one another. In this case, it is possible to guide the optical single fibers substantially in one plane, whereby the risk of twisting of the individual fibers is further reduced.
- the effectiveness of the production process can be advantageously further increased if the individual fibers are unwound from supply rolls and then fed into the production process. This allows the process beneficial ⁇ way be carried out continuously over a long period.
- the supply roll further enables a largely torsion-free storage of the individual fibers prior to their processing, so that they can be supplied to the production process in an inherent ⁇ free manner.
- the axes of rotation of the supply rollers are also at least substantially parallel to the axes of rotation of the deflection rollers. In this way, further sources for a possible torsional load of the individual fibers can be eliminated.
- a further increase in the efficiency of the production method can advantageously be achieved by winding the fiber ribbon onto a cable drum.
- a reel-to-reel process can be realized.
- the Erzeu ⁇ supply of the fiber ribbon after the merge of the individual fibers by extrusion coating of the single fibers with a Hüllmate- rial takes place.
- the shell material is advantageous in addition to a protection against rotation of the fiber ribbons to each other also protects against damage to the surface of the individual fibers. This ensures reliable operation during operation of the fiber ribbon, as a violation of the surface of the individual fibers would have a distortion of the damping properties.
- the individual fibers are guided without torsion during the encapsulation and subsequent hardening of the envelope ⁇ material.
- the Hüllmate ⁇ rial that is not yet cured, there is still the risk of torsion of the individual fibers, which would lead to a reduction in the quality of the produced strip.
- a torsion of the individual fibers during the curing process can be effectively prevented by a torsion-free guidance due to the circumstances already explained.
- the hardening of the wrapping material should be understood in the broader sense as any Ver ⁇ consolidate the wrapping material after encapsulation. Curing can for example be done by selecting a suitable plastic by UV light irradiation. When using thermoplastics as wrapping material is understood as a curing process, the cooling and thus solidification of the shell material.
- FIG. 1 schematically shows an embodiment of the method according to Invention ⁇ and Figure 2 shows the section II-II according to FIG. 1
- a production plant according to figure 1 four A ⁇ be zelfasern 11 to a fiber ribbon 12 (which for example, may come as a pedestrian sensor in the bumper of a motor vehicle for switching on set) together after these sections by means of La ⁇ fibers 13 to a surface treatment were subjected.
- the individual fibers 11 are unrolled from supply rolls 14 and run each Umlenkrol ⁇ len 15a on a collecting roller 16 with a relatively large extent together, on which they are performed in parallel according to their location in the fiber sliver 12 to be produced.
- the guide on the deflection rollers 15a simultaneously enables the surface treatment by means of the laser 13, since the deflection rollers 15a form a base on which the individual fibers 11 can be guided past the laser 11 with high precision.
- the four individual fibers are unwound and jointly supplied via further deflection rollers 15b paral lel Gradient ⁇ a extruder 17, in which they are overmoulded with a covering material. Subsequently ⁇ is impactedd the resulting slivers fed to a Aushärtungsrange 18 12 (UV light) having a linear guide 19 for the to be cured optical fiber ribbon 12 and a light source 20 for the necessary for curing electromagnetic radiation.
- the out ⁇ is hardened over a band buffer 21 and thus completed slivers further To ⁇ castors supplied 15c and rolled over them on a cable drum 22nd With the help of the cable drum, the Faserbänd ⁇ Chen can be fed to a further processing.
- the fiber strips are cut into suitable sections and connected as a sensor strip having a light emitting diodes and photodiodes having evaluating unit (not Darge ⁇ asserted).
- a section through the collecting roller 16 and one of the deflection rollers 15a is shown, wherein these rollers are profiled on the circumference in such a way that the individual fiber 11 rests on the profiles 23 over a large part of its circumference.
- the profiles can be provided in a manner not shown with a rubber layer to further complicate slipping of the bands.
- the axes of rotation 24a of the guide rollers 15a and the collecting roller 16 and the axes of rotation 25b of the supply rollers 14 are all parallel to each other, d. H. perpendicular to the plane of the drawing shown in Figure 1.
- the axes of rotation 24 c of the other rollers 15 c, 21 and 22 are perpendicular to the plane of the drawing, so that the winding of the fiber sliver 12 produced can be largely torsion-free.
