Definitions
- the invention relates to a method for producing blanks from an elastic paper, for example from a creped paper, paper webs drawn off from a roll being brought together in pairs one above the other and then the blanks being cut out in a rotary cutter comprising two rollers.
- the invention further relates to an apparatus for performing such a method.
- the present invention has for its object to develop a method for producing blanks from an elastic paper, preferably a creped paper, in which web tension problems are avoided in a simple manner and which overall enables extremely economical production of blanks.
- This object is achieved in that first all paper webs are pulled from a common mother roll and formed by cutting the stripped mother roll web and then two paper webs are brought together and then cut alternately starting from the two sides of the superimposed paper webs in the rotary cutter.
- a device for carrying out the method, comprising a roll holder and a rotary cutting device comprising two rolls, the rolls of which are designed as transport rolls at least on a partial area of their circumference, is characterized in that both rolls are provided with cutting knives arranged offset in the circumferential direction and in their cutting knife-free areas are designed as counter-rollers for the cutting knife-equipped areas of the other roller.
- Such a rotary cutter of a corresponding device allows on the one hand the problem-free transport of the two superimposed paper webs and on the other hand the equally perfect and mutual cutting of the superimposed paper webs leading to the tension compensation.
- FIG. 1 shows a schematic illustration of an apparatus for producing blanks from creped paper. Overall, this device is provided with reference number 10.
- the essential components of this device initially include a roll holder 11 for a mother roll 12, a cutting mechanism 13 for longitudinally cutting the mother roll web 12a drawn off from the mother roll 12 into two individual paper webs, two folding stations 15 for folding together the two paper webs 14, two embossing stations 16 for embossing cutting boundary lines in the Area of the folded paper webs 14 and a rotary cutter 17 in which the two folded, embossed paper webs 14 are brought together and cut.
- the rotary cutter 17 is shown in FIGS. 2 to 4.
- This rotary cutter 17 comprises two rollers 18 and 19, each of which is provided with cutting knives 20 and 21, respectively.
- each roller 18 and 19 each extend only over a partial area of the circumference of said rollers 18 and 19.
- this area equipped with cutting knives 20 and 21 corresponds in each case to approximately half the circumference of the two cutting rollers 18 and 19.
- FIG 4 also makes it clear that the cutting knives 20 and 21 of the two rollers 18 and 19 are offset from one another in the circumferential direction.
- rollers 18 and 19 are designed as counter-rollers for the areas of the other roller equipped with the cutting knife.
- rollers 18 and 19 are designed as transport rollers in a known and therefore not shown in detail.
- FIG. 4 also shows very clearly that with a rotary cutter 17 designed in this way, two superimposed paper webs 14 are cut alternately starting from the two sides of the superimposed paper webs 14.
- the two cutting knives 20 and 21 of the two rollers 18 and 19 are to be designed in mirror image to one another in order to always achieve the same cut shape, regardless whether to cut with the roller 18 or the roller 19.
- the shape of these bag-like blanks 22 can essentially be described as trapezoidal.
- the rotary knives 23 of this cutting mechanism 13a have a wave shape, as seen in the circumferential direction, so that there is a wave shape in the region of the cutting edges with respect to the paper webs 14 cut from the mother roll web 12a.
- This waveform permits a largely waste-free arrangement of the individual blanks 23, which partially overlaps in the longitudinal direction of the paper webs 14, which FIG. 6 shows very clearly.
- the two folded and embossed paper webs 14 are brought together and placed one above the other in the rotary cutter 17, the structure and mode of operation of which were explained above.
