Manufacturing method of dried film roll |
| abstract |
An object of the present invention is to reduce the occurrence of film breakage in the portion holding the film in the tenter stretching device. The present invention provides a method for producing a film roll, comprising a step of unwinding a film from a raw film roll and conveying a film roll using a tenter stretching device to produce a dried film roll. The process of unloading the film, the process of drying while holding both ends of the film parallel to the conveying direction of the film, the process of releasing the holding after drying, and the process of winding the film to obtain a dried film roll step, the holding part is formed by a base and a holding part, the film is held between the base and the holding part, and the space between the base and the holding part The entire end portion of the film contact surface of the grip portion that is in contact with the film has a curved shape smaller than the thickness of the film. |
