    摘要： A laminating machine for producing multilayer films, which comprises at least one first unwinding assembly (3) for a first film (4), at least one second unwinding assembly (6) for a second film (7), and at least one third unwinding assembly (9) for a third film (10); laminating means (12) being for laminating together the films (4, 7, 10), with the interposition of an adhesive material, in order to obtain a multilayer laminated film (13), and applicator means (14) of the adhesive material, which are arranged upstream of the laminating means (12); downstream of the laminating means (12), there is also at least one winding assembly (15) for the multilayer laminated film (13); the first unwinding assembly (3) and the second unwinding assembly (6) are arranged along a first direction of extension (100a) of the machine; the third unwinding assembly (9) is arranged along a second direction of extension (100b) of the machine which is substantially transverse with respect to the first direction of extension (100a), and is positioned laterally with respect to a vertical plane (101) which is substantially parallel to the first direction of extension (100a) and passes through the first unwinding assembly (3) and the second unwinding assembly (6).

    摘要： The present invention concerns a plant (I) for the production of multilayer panels comprising: an operating station (3) capable of applying an adhesive material on at least a surface of a first layer (10) and/or at least one surface of a second layer (11), to be combined with said first layer (10); a support conveyor (55), arranged downstream of said operating station (3), intended to receive said first layer (10); an overlapping station (5) arranged adjacent to said support conveyor (55) and intended to receive said second layer (11) from said operating station (3), wherein said overlapping station (5) is configured to overlap said second layer (11) on said first layer (10), so that said at least one surface of said first layer (10) is in contact with said at least one surface of said second layer (11) to form a multilayer panel.
    The present invention also concerns an overlapping station (5) and a method of producing multilayer panels.

    摘要： The present invention is a method for separating a copper-copper laminate having a first structure in which a first copper conductor film is provided on a joining surface, a second structure in which a second copper conductor film is provided on a joining surface, and a cross-linking layer that includes nanocrystals of copper(II) oxide and that is located between the joining surfaces of the first and second structures, the method for separating a copper-copper laminate involving cooling the cross-linking layer to a temperature equal to or lower than the antiferromagnetic magnetic transition temperature of copper(II) oxide and separating the joining surfaces of the first and second structures. The temperature to which the cross-linking layer is cooled may be lower than the temperature at which the thermal expansion coefficient of at least the copper(II) oxide transitions to a negative value. The nanocrystals of copper(II) oxide included in the cross-linking layer may be derived from a cross-linked substance produced through a vapor-assisted procedure for irradiating the nanocrystals with vacuum-ultraviolet light.
