Abstract (en)

[origin: WO8501916A1] A method for producing self-copying printed matter comprising at least two sheets joined to form a so-called form set or the like, which sheets are coated with a copying layer and which printed matter is formed by bringing paper webs coated with copying layer and provided with print to lie one upon the other in an intended order of sequence in a form set or the like, whereafter the paper webs are partially fastened to one another and cut to a length corresponding to the length of a form set. In accordance with the invention, the paper webs are produced by coating a wide paper web (2), having a width corresponding to the total width of the sheets forming part of at least one item of printed matter, in web sections (16-19) of mutually equal width parallel with the paper web (2), each of the web sections having a width corresponding to the width of a finished item of printed matter, such that respective web sections (16-19) are coated with a copying layer on one side (20) the other (21) or on both sides of the paper (2) depending upon whether respective web sections (16-19) are intended to form the uppermost sheet, the lowermost sheet or intermediate sheets in a finished item of printed matter. A thus coated paper web (4) is divided into two or more longitudinally extending narrow paper webs prior to combining the webs to an item of printed matter, each of these narrow paper webs corresponding to a web section (16-19). The invention also relates to paper coated in web sections (16-19) of mutually equal widths parallel with the paper web (2).
