Patent ID: 7815765

Claim:
A method for manufacturing or forming a laminated synthetic leather, said method comprising: providing a carrying roll, engaging a textile carrier onto said carrying roll, providing and disposing a lamination roll close to said carrying roll, providing an extruder machine to extrude a material into a film, downwardly feeding said film onto said lamination roll, to have said film carried on a roll segment of an outer peripheral portion of said lamination roll, and to have said film to be suitably cooled by said lamination roll, said roll segment having two ends, a first end disposed where the film begins to contact with the lamination roll at 89 degrees above the horizontal plane measured through the plane where the carrying roll and the lamination roll contact intersecting at the lamination roll axis, a second end disposed where the film leaves the lamination roll at 1 degree above the horizontal plane measured through the plane where the carrying roll and the lamination roll contact intersecting at the lamination roll axis, whereby said film contacts said lamination roll over a sufficient segment of the lamination roll to provide a substantially constant thickness of said film, providing a passage in said lamination roll, feeding a cooling fluid through said passage of said lamination roll to cool said lamination roll and to cool said film when said film is carried on said segment of said outer peripheral portion of said lamination roll, compressing said film and said textile carrier together with said carrying roll and said lamination roll, to form said laminated synthetic leather, and to prevent said film from being completely penetrated into said textile carrier, wherein the horizontal plane is horizontal to the ground and the point of contact of said lamination roll and carrying roll is a line, not a plane, said roll segment is the entire surface of said lamination roll that the film contacts.
