A method of making and using computer paper as a roll and a device for carrying out the use phase.

The invention relates to a method for producing and using computer paper as a roll. The invention also relates to a device for carrying out the operating step of the method.

Chain forms used in computer printers today are produced on an expensive printing press, regardless of whether the forms are printed or not. In practice, the method works by first making a paper web of suitable width as a roll. From the roll, the webs are passed through a printing machine, where edge holes are made in the web for the printer's pulling device, as well as cross-perforation at a distance corresponding to the desired form length. The web is folded from the perforation points and folded into boxes into a package. The printer pulls the pleated web out of the box with its own puller.

The object of the invention is to provide a method and a device by means of which the use of expensive printing machines for the production of computer paper can be avoided, while achieving a higher production speed and a smaller storage volume.

This object is achieved on the basis of the features set out in the appended claims.

The invention will now be described with reference to the accompanying drawings, in which Figure 1 shows a schematic side view of an apparatus for carrying out the manufacturing method according to the invention and Figure 2 shows a schematic side view of an apparatus for carrying out the method.

In Fig. 1, reference numeral 1 denotes an automatic output winding station in which a paper web 9 is drawn from a large and wide paper roll 7. The width of the roll 7 may be several meters (e.g. 1.5 ... 8.6 m) and the diameter e.g. 1.5. ..

2.2 m. The web 9 is led through the web guide station 2 to the edge perforation unit 3, where the longitudinal rows of holes are driven by the perforating rollers, the width of which is standardized according to the pulling devices of the printers. In the longitudinal cutting station 4, the web 9 is divided by longitudinal cuts into several narrow webs, the width of which corresponds to the final working width of the computer printer. The web strips formed in the cross-perforation station 5 are perforated transversely with a distance corresponding to the desired fold length. The computer paper webs 10 thus prepared are wound into small rolls 8 in an automatic take-up reel unit 6. The weight of the small rolls 8 can be, for example, 9 to 12 kg, whereby they can be handled by hand in office conditions.

In the application of the computer paper (Fig. 2), the small roller 8 is placed on the spool of the commissioning device, which is connected to the motor 13, which is controlled by the printer 11, as shown by the dotted line 12. The motor 13 rotates the roller 8 as the printer 11 pulls the paper. In this case, the drive of the printer 11 does not have to rotate the roller 8, the inertia of which in many cases is too great for the drive of the printer. The printed paper web folds at the cross-perforations and folds in the usual way into the box 14.

Claims (2)

1. A method for making and using ATK paper as roll goods, characterized in that, from wide paper rolls (7), several narrower small rolls (8) are produced by ATK paper by interposing in the paper web, (I) between the rollers (7, 8) make longitudinal rows on both sides of the prospective longitudinal points, (II) longitudinal sections and (III) transverse perforations in a known manner. to correspond to the desired sheet size, after which the webs separated by longitudinal sections are flushed into small rollers (8) from which the ATK paper is put into use by pulling the paper web (10) from the roll (8) to a printer (11) thus, through the paper feeding of the printer. control is controlled the rotation reducing motor (13) of a roller (8). 2. Device for carrying out the commissioning stage in a method according to claim 1, characterized in that the commissioning device of the small rollers (8) joins a motor (13) which receives its control from the printer (11) so that the ATK paper web (10) between the roller (8) and the printer (11) is sufficiently loosened to allow the pulling device of the printer (11) to pull the paper web (10) from the roller (8).
