发明名称 Device and method for joining layers for forming sheet products and resulting products
摘要 The device comprises an essentially rigid smooth first cylinder ( 1 ) and an essentially rigid second cylinder 83 ), the latter having points ( 3 P), the first and second cylinders rotate in opposite directions about respective axes of rotation ( 1 A, 3 A) and are pressed against each other, thus defining between themselves a lamination nip ( 5 ), through which said at least two layers are passed. There is also a pressure roller 87 ), with a surface ( 7 A) that is less rigid than the first and second cylinders ( 1, 3 ), this roller interacting with the second cylinder and being pressed against it. The pressure roller forms with the second cylinder ( 3 ) an embossing nip ( 9 ) through which the layers (V 1, V 2 ) previously laminated in the lamination nip ( 5 ) are passed and in which they are embossed.
