<p>The Multi-part form set comprises several block-like individual sheets which are positioned over one another and exhibit transfer copying properties and at least a bound edge which holds the individual sheets together via a perforated connection. For the purposes of mechanical printing the set has its bound edge attached to an endless band. After the form set has been written on, the endless web (1) is folded or detached along the perforations in such a way that it forms an envelope with a cover sheet and a backing sheet. The endless band is multi-layered so that after the folding process extra sheets can be added between the cover and backing sheets.</p> |
