In order to use them as outdoor materials, it is necessary to control the thickness of the small number of porous polyurethane soft films to 50 탆 or less .

In the case of separating the soft thin film from the release paper by using a conventional stripping apparatus in the production of a small number of porous polyurethane soft film having a thickness of 50 탆 or less, it is impossible to keep the separation position of the soft thin film and the release paper constant, The excessive softening of the soft thin film after peeling has caused problems of wrinkle generation and hardening of the elongated soft thin film. In order to control the force of the soft thin film to remove the wrinkle and elongate the soft thin film, So that the manufacturing process becomes complicated.

The present invention provides a peeling apparatus for a small number of porous polyurethane soft film which can be controlled to peel off a releasing paper and a soft thin film at a predetermined position from a release paper and a soft thin film having passed through a peeling roller, will be.

Another object of the present invention is to provide a flexible thin film which is wound to remove the wrinkles and remove the tension of the soft thin film by effectively lowering the peeling tension and effectively preventing the soft thin film wound after being peeled from being excessively tensioned. And a peeling device for a small number of porous polyurethane soft film which can omit the step of rewinding.

In order to achieve the above object, according to the present invention, there is provided a laminate supply roller 1 for supplying a laminate on which a flexible thin film is formed on a release paper, a peeling roller 2 for peeling the release paper and the soft thin film, (2) and a release-material-winding roller (6) on a conventional peeling apparatus composed of a flexible thin-film winding roller (3) for winding up a take- (3) is driven in accordance with the vertical distance measured by the distance sensor (4) and a distance sensor (4) for measuring a vertical distance (L1 or L2) between the thin polyurethane flexible thin film A control unit 9 is provided to adjust the rotation speed of the servomotor 8 so that the release paper R and the flexible thin film F can be separated from each other at a predetermined position.

The present invention can control the peeling roller (2) so that the laminate (A) is peeled off at a certain position by the releasing paper (R) and the thin polycational polyurethane flexible film (F) The present invention can effectively prevent the occurrence of wrinkles in the soft thin film wound after peeling due to excessive peeling tension and improve the long-term storage property of the thin thin film through controlling the tension. Thus, rewinding for removing tension and wrinkles can be achieved, The process can be omitted.
