20080292740 | SHEET/FILM MOLDING APPARATUS AND SHEET/FILM MOLDING METHOD - A sheet/film molding apparatus includes: a main roll sandwiches and presses, with a touch roll, a resin molten sheet and conveys the sandwiched and pressed resin sheet; and a separating roll separates the resin sheet from an outer peripheral surface of the main roll and conveys the resin sheet. The separating roll has a rubber roll and a metal elastic external cylinder having the rubber roll housed therein and being eccentrically positioned to the rubber roll and thin and easily elastically deformed. Cooling water is supplied between the rubber roll of the separating roll and the metal elastic external cylinder. The resin sheet between the main roll and the metal elastic external cylinder is cooled by allowing the rubber roll to make pressure contact with an inner peripheral surface thereof. The separating roll separates the resin sheet from the outer peripheral surface of the main roll. | 11-27-2008 |

20090250838 | POROUS FILM MANUFACTURING METHOD AND SUCCESSIVE BIAXIAL STRETCHING APPARATUS FOR MANUFACTURING POROUS FILM - Provided is a method for manufacturing a high-quality porous film. Here, while the porous film is being manufactured through forming micropores by stretching, a raw film is prevented from slipping on the surfaces of the respective rolls as much as possible even though the raw film includes oil or liquid paraffin as a solvent. The method is for manufacturing a porous film through forming micropores by successive biaxial stretching.

20110003672 | SHEET OR FILM-FORMING ROLL - A sheet or film-forming roll 10 includes an inner cylinder member 20 having axial parts 21, 22 provided on both sides thereof and rotatably supported by bearing parts 26, 27 through the axial parts 21, 22, a rubber roll 40 fitted to an outer circumferential surface of the inner cylinder member 20, eccentric side plates 53, 54 rotatably fitted to the axial parts 21, 22 of the inner cylinder member 20 respectively, and an elastic outer cylinder member 50 rotatably supported by the eccentric side plates 53, 54. The elastic outer cylinder member 50, which is provided with a thin-walled structure and made from metal, has an inner diameter larger than an outer diameter of the rubber roll 40 to accommodate the rubber roll 40 in an interior 68 thereof, and has inner circumferential surface 50A coming into contact with an outer circumferential surface 40A of the rubber roll 40. | 01-06-2011 |
20120038080 | FILM STRETCHING MACHINE AND FILM STRETCHING METHOD - A film stretching machine includes a clip chain for holding a lateral edge of a film and stretches the film while transporting the film with the clip chain holding the film and traveling, and includes an upper reference rail disposed at an upper side for guiding the clip chain; a lower reference rail disposed at a lower side for guiding the clip chain; a plurality of clips that constitutes the clip chain; an interval adjusting rail for adjusting intervals of the plurality of clips; and interval adjusting links that couple neighboring clips among the plurality of clips and contact with the interval adjusting rail to adjust the intervals of the plurality of clips. According to the film stretching machine, a stretch degree of a film can be adjusted with a simple configuration and little man-hours. | 02-16-2012 |
