Abstract (en)
[origin: EP0274737A2] The front sheet (38') of a paper web (34) provided with transverse perforations (37') is separated along a separation line (T), which runs adjacently to and at a small distance from a transverse perforation (37'). The paper strip (40) formed in this way is coated with adhesive. Then, the one end of another paper web is applied to this paper strip (40) provided with an adhesive coating (42), without the transverse perforation (37') being covered. The two paper webs are thus spliced together while leaving free the transverse perforation (37'). This makes it possible for the spliced material webs to be folded or separated along this transverse perforation (37'), without leading to difficulties. The "fold memory" created by a prior prefolding at the transverse perforation (37') is maintained. <IMAGE>
