提高第一幅面状材料的第一表面和第二幅面状材料的第一表面之间的粘附力的方法
摘要：
本发明涉及提高第一幅面状材料的第一表面和第二幅面状材料的第一表面之间的粘附力的方法，其中将所述第一幅面状材料和所述第二幅面状材料连续地并且以相同的幅面方向引导至层压辊隙，在所述辊隙中将所述第一幅面状材料和所述第二幅面状材料各自以其第一表面层压在一起，用等离子体在整个面积上处理所述第一幅面状材料和所述第二幅面状材料两者的第一表面，并且特别地以这种方式，使得等离子体从所述层压辊隙前的区域开始连续地作用在两个第一表面上直至进入所述层压辊隙，所述层压辊隙由加压辊和反向加压辊形成，并且辊的至少一个表面或两个表面装配有电介质，等离子体或电晕由喷嘴产生，其中所述第一幅面状材料包括胶粘剂组合物层，将所述胶粘剂组合物层如此布置在所述第一幅面状材料中，使得其形成第一幅面状材料的第一表面。
摘要（英）：

The invention relates to a method for increasing the adhesion between the first surface of a first web-type material and a first surface of a second web-type material, the first web-type material and the second web-type material being supplied to a lamination nip continuously and with the same direction of the web. In said nip, the first surface of the first web-type material and of the second web-type material are laminated together and both first surfaces of the first web-type material and of the second web-type material are treated with a plasma over the whole surface, in particular such that the plasma acts continuously on the two first surfaces starting from a region in front of the lamination nip to right into the lamination nip. The lamination nip is formed by a pressure roller and a counter-pressure roller and at least one of the surfaces of the rollers or both are equipped with a dielectric. The plasma or the corona is produced by a nozzle. The first web-type material comprises an adhesive compound layer which is arranged in the first web-type material such as to form the first surface of the first web-type material.
