Description

Block that can be pulled apart like scales The innovation affects one block that can be pulled apart like a scale.

Blocks that can be pulled apart like scales are used in form technology known per se. In the production of this well-known block is made of a fan-fold or zig-zaek-like folded spine or carrier sheet assumed, its Leporello or Zigzag folds can be pulled apart, with every second of the folds of the Carrier sheet allows you to attach a set of forms, consisting of consists of an original and a copy.

In order to be able to produce these blocks more efficiently, it is already there known to print original and copy on a single sheet, this sheet in an exit center line and fold on both sides, d. H. against each other around 1800 to print staggered places. The relief caused by this type of production but is partly nullified by the fact that the sheets are printed twice must be clamped in the printing press to ensure the printing on both sides to achieve, or that a special machine must be used, which on both sides printed.

The innovation is based on the task of making a scaly-like pull-out To create a block in which the fan-fold or zigzag-shaped spine is omitted comes in which the form sheets only need to be printed on one side and the can be glued by machine.

This task is performed with a double block that can be pulled apart like a scale, consisting of a large number of superimposed, by mutually parallel strip-shaped Adhesive connections of sheets united with one another are solved according to the new invention, that in each case one sheet with the next one on one side by means of a central adhesive connection and with the next one on the other side by two equally spaced from the middle adhesive connection is connected outer adhesive connections, and that the sheet between the Middle adhesive connection and the outer adhesive connection each has two folds, one next to the central adhesive joint and another next to the external adhesive connection.

It can be seen that this arrangement of the adhesive points according to the innovation on one and the same sheet can be repeated as often as desired, so that in the printing press also many forms side by side on a single sheet CD can be printed as the size of the printing press allows; the adhesive bonds for a large number of double-block sheets can also be applied to one sheet at the same time. In this case, the double blocks of forms are cut out of the stack of sheets after the sheets have been combined.

The folds are expediently pre-formed by line perforations. In addition to the line perforations defining the folds, further perforations be provided, which are used to tear off individual sheets of the double block.

The double block can be used as such. It is also possible to produce two single blocks from a double block. This is done by that one cuts through the double block along a center line of the central adhesive connection. The scale-like pull-out of the resulting individual blocks is retained.

The enclosed figures explain the innovation. They represent: 1st figure from above plan view of a double block according to the innovation, 2nd figure of above view of an exploded in the direction perpendicular to the view of the top figure Double block in profile, 3rd figure from above Profile of a half-expanded one Double blocks, 4th figure from above Top view of an exploded double block.

The innovation is particularly clear from the top two figures. In the second figure from above, 1 denotes an original sheet, and 2 denotes a carbon copy sheet. If one takes out the middle original sheet 1, it can be seen that this is connected to the lower copy sheet 2 in two outer splices and with the upper copy sheet 2 in a middle splice. Folded edges are formed between this central adhesive point and the two outer adhesive points, each of which is very close to the adhesive point. The sheet sections lying between the folding edges are decisive for the g Scale width of the scale-like stretched apart block C> in such a way that a flake width is equal to twice the width of the distance between the folds. In the top figure 6 perforations are shown. As can be seen from a comparison of the two top figures that belong together, the 4 inner perforations correspond to the folding edges, while the two outermost perforations are also present and serve to tear off the sheets.

The manufacture of single blocks from the double block according to the two topmost figures are made by separating the double block along one in the middle the dividing line lying in the middle of the adhesive bond.

Claims (3)

Protection claims 1. Double block that can be pulled apart like a scale, In particular, double blocks of forms, consisting of a large number of one on top of the other Sheets, which are bonded by adhesive strips running parallel to one another are combined with each other, characterized in that each sheet with the on the one hand next by a central adhesive connection and with the on the other side, next by two equidistant from the central adhesive joint located outer adhesive connections is connected and that the sheet between the middle adhesive connection and each of the outer adhesive joints has two folds, one next to the central adhesive joint and another next to the external adhesive connection. 2. Double block that can be pulled apart like a scale according to claim 1, characterized in that the folds are formed by perforations. 3. Double block which can be pulled apart like a scale according to claim 1 and / or 2, characterized in that, in addition to the perforations defining the folds, there are further perforations located outside the outer adhesive points. 4. Single block that can be pulled apart like a scale, thus identifiable CD characterized in that it is produced by dividing a double block according to one of Claims 1 to 3 along a center line of the central adhesive connection.
