Definitions
- the invention relates to a slitter for a Material web with an inlet section, an outlet section and in between a cutter one arranged in the area of at least one edge Edge trimming device for producing an edge strip.
- the invention is based on a paper web described as an example of the material web. she is but can also be used with other material webs, for example for foils made of plastic or metal or for cardboard.
- the desired smooth edge which will later be available for sale Winding rolls to a flat face leads. Since the paper webs in usually cut into several partial webs anyway be, the width for a user, for example a print shop that is manageable can be found at this Opportunity also with the edges of the paper web trimming. In the cutter are therefore in usually in the area of the two longitudinal edges of the paper web Knives or other cutting tools arranged, which should smooth the edges of the paper web that they cut off a relatively narrow margin. The edge trim can be made directly in the paper mill the pulper to be fed back into the Production cycle to arrive.
- the invention has for its object the quality to improve the bleed.
- This task is the beginning of a slitter mentioned type solved in that the edge trimming device a pulling device is assigned, that acts on the edge strip.
- the traction device is preferably a pair of clamping rollers educated. With a pair of pinch rollers apply a relatively clearly defined tension, so that the edge strip with the necessary tension is pulled.
- both rollers of the Project the pair of pinch rollers laterally over the edge strips and one running to the side of the edge strip Affect the area of the material web.
- the pair of pinch rollers at least covers the cutting line, so that the main part of the material web and the edge strip is subjected to the same tensile force become. This allows a very clean one Cut, especially when the pinch roller pair arranged relatively close to the edge trimmer is.
- One roller of the pair of pinch rollers is advantageous designed as a guide roller for the cut material web. Since you cut the material web around anyway the guide roller must guide to further processing can be fed, this guide roller also the same use as a roller of the pinch roller pair.
- one roller of the pair of pinch rollers is as Pinch roller trained only on the verge and the adjacent strip of the material web acts. You can then use a roller with relative for the pinch roller use short axial length so that the additional Compared to conventional roll cutters, small remains.
- the material web is advantageously behind in the running direction an edge strip receptacle is arranged in the pulling device. So you can take the border strip a little further arrange away from the edge trimmer and nevertheless, a targeted feed to the verge intake to reach.
- the supply takes place through the Towing equipment.
- the traction device can thus be denser be moved towards the edge trimmer, which in turn improves the quality of the edge trim allowed.
- the edge strip receptacle is advantageously used as a suction device educated.
- the edge strip is thus relatively quickly from the area behind the drawbar away.
- the tension arrangement is advantageously a spreader device subordinate.
- the spreader device works but only on the cut main part of the Material web, but not on the edge strips. Hereby the partial webs are a small distance separated from each other.
- the traction device is advantageously a further treatment device for the material web without edge strips subordinate, with means being provided which Tensions of the further processing device and the traction device match up.
- a post-processing facility is for example a roll winder, where the material web or its partial webs too Winding rolls are wound up. For winding up is one some tension necessary. If you take the tension that the pulling device on the edge strips and if necessary exercises adjacent areas of the web so synchronizes or matches to get a clean edge trim without doing so a pulling direction deviating from the running direction to get the web of material.
- a slitter winder 1 serves a material web 2, for example a paper web, into several partial webs 3 and to divide two edge strips 4. Tried here one, for example, damage to the Edges 5 of the material web 2 have occurred, so cut off.
- the winder 1 has this in a known manner a cutting device 6, the several, on the Width of the material web 2 distributed knife 7 and in the Near the edges 5 each has a knife 8.
- Knives serve as edge trimming device.
- "Knives” are understood to mean all cutting devices with which a longitudinal section of the material web 2 is possible. Usually these are against each other running knife disks based on the silhouette principle work. But there are also others Cutting devices conceivable, such as those with sharp water jets or with laser jets work.
- the tension of the partial webs 3 in the further processing device 10 determine and to a control device 19 pass on.
- the control device 19 is with the drives 20 then to be used for the Pinch rollers 16 connected. In this way it is possible the tensile stresses for the edge strips 4 in particular to precisely match the tensile stresses of the partial webs 3, so that no change by the pinch rollers 4 the course of the partial webs 3 is effected.
- An inlet section is located in front of the cutting device 6 21, arranged in the further guide rollers 18 could be.
