Abstract (en)
A method for realising optimised four-ply toilet paper in which plies (21-24) are fed to a gluing group thereof for realising a log, which foresees introducing the plies (21-24) between two steel rollers (26, 26') after at least a pair of plies (21-22; 21-23) is made to pass between a first pair of rubber and steel rollers (25 and 26, respectively) and has received glue through a roller (27) and the remaining plies are made to pass into a second pair of rubber and steel rollers (25' and 26', respectively), once again separating at least one outer ply (21; 21,22,23) from said four-plies (21-24) to feed it to a pair of rollers (29, 30), one (30) of which foresees an imprinted design before receiving glue from a further roller (31), and finally feeding at least one outer ply (21; 21,22,23) provided with glue and the remaining plies (22-24; 24) to a coupling roller (32) which determines the final sticking together of the four plies (21-24). The steel cylinders (26, 26') are alternatively of the point-to-point type. <IMAGE>
