Abstract
A clip (10) has a frame (31) and a flapper (32). Two dry bearings (37) are inserted into a hole (32d) formed in the flapper. Then an attaching shaft (35) is inserted from one of the holes (34a) in the frame (31) to the other through the dry bearings (37), so as to swingably attaching the flapper (32) to the frame (31). DAIDAYNE DDK 01 of DAIDO METAL Corp. is used as the dry bearing (37). A first and a second clip covers (51,52) are provided to cover the clips (10). Fresh air feeding pipes (55) are connected to the first and second clip covers (51,52). Fresh air is fed from the fresh air feeding pipes (55) toward the clips (10) through air outlets (56) provided in the first and second clip covers (51,52).
Claims13
A tenter device used in a solution casting apparatus comprising:
- clips for clipping a film and moving for transporting said film, between a clip start position for clipping lateral edges of a film and a clip release position for releasing said clipping of said film;
- a dry air blower for feeding dry air toward said film for drying said film while said film is transported;
- and
- a clip cover for covering a moving path of said clip in clipping said film;
- and
- a fresh air blower for feeding fresh air into inside of said clip cover so as to prevent said dry air in outside of said clip cover blowing into inside of said clip cover.
A film drying method for drying a film produced by solution casting, said film being dried by dry air fed from a dry air blower while said film is transported, said transporting of said film being performed by clips for clipping said film and moving between a clip start position for clipping lateral edges of said film and a clip release position for releasing said clipping of said film, said film drying method comprising:
- moving said clip, which is covered by a clip cover, cyclically from said clip start position to said clip release position;
- and
- feeding fresh air into the inside of said clip cover by a fresh air blower so as to prevent said dry air outside of said clip cover from blowing into the inside of said clip cover.
