Definitions
- the invention relates to a cutting device for a Material web, in particular a paper or cardboard web, with a row of knives that extend across the width of the web extends and has several knives with Distance to each other in a row next to each other are.
- the web is first of all with the help of Cutting device cut in the manner of a perforation so that a series of relatively short cuts is introduced in a row next to each other. Between the short cuts remain webs on which the web still going through.
- This cut which is also called Perforation line can be referred to in one certain distance from the actual separation point be introduced.
- the actual separation takes place then later by moving the web to a specific one Position is subjected to an increased tension.
- the remaining webs then tear off here.
- Such Procedure has the advantage, for example, that the already weakened or perforated web pass through part of a processing device can, for example, locally with an adhesive application to be provided or a winding position to reach.
- the invention has for its object the weakening and the strength of a material web better on each other to be able to vote.
- This task is the cutting device initially mentioned type solved in that a second Row of knives is provided in the second knife spaced apart and parallel can be moved to the first row.
- the knives of the first row and the knives of the second row are initially arranged so that they are at least largely one behind the other in the running direction of the web. In this position, the webs remaining between the incisions have the greatest width. If you now move the two rows of knives against each other transversely to the direction of travel of the web, the knives of the second row come out behind the knives of the first row and narrow the gap, so that the webs that remain after perforating have a smaller width. The smaller the width of the remaining webs, the weaker the web and the less tension that is necessary to tear the web.
- the knives of the first row and the Knives of the second row touch each other.
- the individual cuts can be created continuously, without between the two rows of knives in the Material web or webs remain. With that in mind the individual cuts do not differ from those that with a cutter with only one Knife row can be made.
- the knives of the first row and the Knives in the second row each have a cutting edge and the cutting edges lie against each other.
- the danger that the Ends of each cut result in cracks that result in a unintentional weakening of the web could be kept small.
- At least one position is preferably the second Row adjustable relative to the first row in which all Knives of the second row from the corresponding knives the first row are covered. This position sets the least possible weakening of the web. This position can then be said to be the weakest Goods web can be optimized. If so, webs of goods to be cut, the higher tear strength then the two rows of knives just shifted against each other.
- the knives of the first row and the knives of the second Row each with the same width and the same division exhibit. You could say that you have identical rows of knives use. This configuration is therefore constructive very simple and facilitates stock keeping for the knives.
- the knives in the first row are wider than those in the second Are row and have a different division.
- this Design is no longer necessarily created bars of equal width when the two rows of knives face each other be moved. The probability, that all bars disappear due to a too large displacement, is however relatively small.
- One becomes in both Alternatives of course take any measures to shift the two rows of knives against each other limit, for example a stop for the Provide row of knives to be moved.
- the individual webs that remain should become very thin, it can be better, fewer bridges, but with to provide a larger width. This can be very easy to achieve with the design described.
- the second row of knives is preferred larger than the distance between the knives in the first row. In order to the desired variation of the web widths can be easiest to achieve.
- the knives are preferably the first and the second Row arranged in groups, being between groups a gap remains that is larger than the distance the individual knives in a group.
- This configuration is particularly advantageous if you have two rows of knives used with different width knives, whose division is different from that.
- One can then with the grouped subdivision ensure that in one position only the knives of the first row become active because they are the second row knives cover completely, and in the other extreme position take care of the second row knives that the remaining webs in the web are narrow become.
- the configuration is particularly preferred when the knives interact with a counterholder, that has at least one strut, whose position matches a gap. Through the Subdivision of the knives into groups then remains a relatively wide bridge in the area of the gap. Therefore but relatively wide webs can be cut.
- Fig. 1 shows a cutting device 1 for cutting a web 2, for example a paper web or box.
- the cutting device has a rotary crossbeam 3, to which a knife assembly 4 is attached. If the web 2 moves in the direction of an arrow 5 and the rotary cross member 3 rotated in the direction of an arrow 6 is, then the knife assembly 4 dips into the web and perforate them as described below becomes. If the rotational speed of the rotary crosshead 3 on the feed speed of the web 2 is coordinated, then only arise relatively narrow cuts.
- a counter-holder 7 which has recesses 8 has, in which the knives of the knife assembly 4 enter can.
- the knife arrangement 4 a plurality of knives 9, each in Groups 10 are arranged. Between individual groups there are gaps 11 that are so wide that struts 12 fit between the individual recesses 8 are provided in the counter holder 7.
- the knife 9 can be designed as individual parts and, as shown, parts of a one-piece design Knife bar.
- the knives 9 are, as can be seen from FIGS. 1 and 3, divided into two. So there are a number of first knives 14 and a series of second knives 15 which abut one another.
- the first knives 14 have a Cutting edge 16 on its "back” while the second knife has a cutting edge 17 on it Have "front”.
- the two cutting edges 16, 17 lie on both sides of an imaginary plane and with each other.
- the first knives are located 14 and the second knife 15 are congruent with one another. They are the same size and have the same Distance from each other. The sum of one knife width a and the distance b to the next knife also called "division".
- This cutting plan will be chosen for material web 2 with the lowest tear strength. As can be seen from the following explanation, the remaining webs 19 with the width b are the largest here. For example, one will choose such a cutting plan if the web 2 is a paper with a basis weight of 40 g / m 2 . In this case, the width a of the knives 14, 15 is of the order of 5 mm and the width b of the webs 19 is of the order of 1 mm.
- FIG. 5 shows an embodiment of a knife arrangement 4 ', which largely corresponds to that of FIG. 4.
- the knives 14, 15 are the same size and in the representation 5a arranged congruently to each other.
- the adjustment of the knives to one another is expediently carried out with an eccentric, e.g. on an axial End of the rows of knives is arranged. Since the Adjustment path located in the millimeter range is one such adjustment device sufficient.
- Fig. 6 shows a third embodiment, in the same and corresponding parts with the same reference numerals as shown in Figs. 4 and 5.
- the knives 14 are no longer the same size as the knives 15.
- the knives 15 in the second row have rather a reduced width and a greater distance to each other,
- the division differs the knife 15 from the division of the knife 14. This leaves for example in the left half of FIG. 6a detect.
- 6a shows an operating state in which the knives 15 are completely covered by the knives 14. Accordingly the same cutting plan as in 4a with incisions 18 of width a and webs 19th the width b.
