<p>In methods of this type, the parts to be fixed or the roll material to be laminated are/is transported between two air-impermeable conveyor belts through a heating-pressing zone and thereafter through a cooling zone. …<??>As practice shows, inclusions of air and vapour in the parts to be glued to each other under the effect of heat and pressure often impair the uniform adhesion of the parts glued to each other over their surface. …<??>To remedy this, it is proposed to generate a partial vacuum in the intermediate space (Z) between the two conveyor belts (1.1/1.2, 2.1/2.2). For this purpose, use is made of channel-shaped suction nozzles (8), having flexible sealing strips (8.21, 8.22) and connected to a suction turbine (10), between which nozzles the conveyor belts, arranged one above the other, preferably slide on both sides. …<IMAGE>… </p> |
