The pre-bonding roller group includes a large roller and a plurality of guide rollers disposed around the large roller, and at least one first heating unit is disposed in the large roller or a position corresponding to an outer edge of the roller surface. The laminating roller group, which is disposed at the other side of the pre-bonding roller group.

The present application relates to a laminating machine, including a first heating device, a first sheet material device, a second sheet material device, and a first combining device, the first combining device includes a heating mechanism and a rolling mechanism. A first sheet material, a first material strip, and a second sheet material are heated and pressed by the heating mechanism and the rolling mechanism, compared with a combination method of a PET film and an oven, it is not necessary to set arrange the PET film, cost of the PET film, arranging a PET film unwinding mechanism, and arranging a PET film winding mechanism is reduced, and occupied space is reduced, manufacturing cost is reduced, and there is no need to set up a longer oven, which improves combination efficiency and production efficiency, and further saves space and reduces device cost.

A composite fabric includes a nonwoven fabric layer having non-bonded areas and a structured film layer discontinuously bonded to the nonwoven fabric layer. The discontinuously bonded nonwoven fabric layer and the structured film layer share an overlapping area with at least one set of coincident bond sites. The discontinuously bonded nonwoven fabric does not have another bonding pattern in the overlapping area distinct from the at least one set of coincident bond sites. A method of forming a composite fabric is also described. The method includes forming a fiber layer including a mat of at least partially unconsolidated fibers, positioning a structured film layer and the fiber layer such that they overlap, and discontinuously bonding the mat into a discontinuously bonded nonwoven fabric while simultaneously bonding the structured film layer to the nonwoven fabric layer. An apparatus for forming a composite fabric is also described.

The present invention relates to a method for surface coating a plane metal substrate, the method comprising the following steps: Providing a coiled plane metal substrate; unwinding the coiled plane metal substrate; applying a polyester based adhesive onto a top surface of the unwound plane metal substrate, and laminating a film comprising a base acrylic layer onto the polyester based adhesive, thereby forming a laminated assembly. The invention further relates to a pre-coated metal substrate obtainable by the method according to the invention, and to a product comprising a pre-coated metal substrate according to the invention.

A method of evaluating a laminate formed of two or more layers bonded to each other includes an image obtaining step of obtaining a two-dimensional image of the laminate; a detecting step of detecting air-pocket corresponding regions from a two-dimensional image; a characteristic value obtaining step of determining a characteristic value related to areas of the air-pocket corresponding regions; and an evaluation step of evaluating the laminate based on the characteristic value. is a method of evaluating a laminate.

A lamination method, includes: a first coating step of applying any one of a main agent M and a curing agent H of a two-component curable adhesive as a coating liquid to a first web W1; a second coating step of applying the other one of the main agent M and the curing agent H as a coating liquid to a second web W2; and a bonding step of bonding a coating liquid-coated surface of the first web W1 and a coating liquid-coated surface of the second web W2, and of combining the main agent M and the curing agent H to increase a molecular weight. In addition, in the first coating step and the second coating step, the main agent M or the curing agent H is applied by a gravure coater.
