Abstract

A method and a device for widening thin films by gripping the two sides of high-molecule thin film and conveying it to the down stream side, mainly comprising: a first belt device(A) having a pair of wheels for expanding the down stream side of the moving direction of high-molecule thin film into a sector shape; a second flexible belt device(B) located above the first belt device(A) of which outside belt surface contacting the outside belt surface of device(B); the said pair of wheels in device(A) capable of moving along the axis 15a and movable in horizontal direction; thereby, adjusting the angle formed by the pair of wheels under the circumstance of unchanged conveying distance in the direction of high-molecule thin film; the outside belt surface of device(B) contacting and applying a pressure on the outside belt surface of device(A) via spring elements, the two sides of high-molecule film gripped between the two outside surfaces and conveyed to the down stream side for widening.
