A roll forming device for plastic flooring utilizes a printed layer unwinding mechanism, a wear-resisting unwinding mechanism and a calender to laminate a substrate layer formed by an extruder, a printed layer and a wear-resisting layer into a whole. The calender includes a gauging roller group, a pre-bonding roller group and a laminating roller group disposed on a rack. The gauging roller group, which is disposed at one side of the pre-bonding roller group and linearly opposite to a discharge port of the extruder. 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.

Absorbent laminated materials that include two spunbond nonwoven layers with a cellulose layer arranged in between the spunbond nonwoven layers are disclosed. The different layers of the absorbent laminated material are bonded through an ultrasonic treatment, and can further undergo an embossing step. In addition, the absorbent laminated materials may be used as disposable wiping products, among other applications.

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 making an electrically-conductive film is provided. The method includes providing a release layer, optionally having a topologically structured surface, and depositing at least one electrically-conductive layer on the release layer whereby the at least one electrically-conductive layer has an outer surface that substantially replicates the topologically structured surface. The electrically-conductive layer can be peeled away from the release layer to obtain the electrically-conductive film. Such electrically-conductive films can be useful in lightning strike applications.

A three-dimensional decorative piece made of a thermoplastic synthetic resin is produced by subjecting, to high-frequency dielectric heating, a decorative piece material that includes an upper layer that includes a thermoplastic synthetic resin film having a vapor-deposited metal layer, an intermediate layer that includes a thermoplastic synthetic resin sheet, and a lower layer that includes a thermal bonding film, the decorative piece including: a first printing layer printed using a transparent color ink, a matte ink, or a glossy ink, as an upper surface of the upper layer; and a second printing layer in which a fine line is printed using a transparent UV ink, on an upper surface of the first printing layer. It is desirable that the fine line of the second printing layer has a width of 0.1 mm to 0.25 mm.
