Abstract: The gluing together of flat materials between belt faces (21, 22), facing one another, of belt conveyors (15, 16) arranged over one another is effected usually with the application of heat and pressure. However there are pressure sensitive materials that with the gluing may only be impinged with a slight pressure. Here already the weight of the sagging belt face (21) of the upper belt conveyor may lead to an excessive pressure loading and a permanent deformation of the materials caused by way of this. The invention solves the mentioned problem in that the upper belt face (21) located above the materials to be glued is held up without contact, e.g., by means of suction nozzles or magnets. The sagging of the belt face (21) is alleviated by way of this and an undesirable high pressure loading of the materials to be glued is avoided. By way of the contactless holding-up of the belt face (21) the suction nozzles or magnets do not interfere.
