Title:
ADHESIVE BINDING METHOD AND DEVICE FOR CARRYING OUT THIS METHOD
Document Type and Number:
WIPO Patent Application WO2005023555
Kind Code:
A3
Abstract:
In order to produce an adhesive binding for bookbinding, in which the sheets, in quarto format, are perforated on the folding edge, folded, provided with adhesive on the folding edge and assembled to form an inner book, the perforating process is carried out on the folding edge in such a manner that two interrupted perforation lines (12, 13) are punched, these perforation lines being parallel at a short distance from one another, offset in a longitudinal direction, and forming a widened folding edge (14). The punch locations of both perforation lines (12, 13) are, along the folding edge (14), offset by the length of one perforating tooth. The quarto format sheets, which are folded on the folding edge (14) and which are assembled and squeezed to form an inner book, are provided with the application of adhesive on surfaces, which are formed by the double perforating and which are assigned to one another, between full locations of one perforation line (12) and full locations of the other perforation line (13).
