Embodiment Construction

[0011] Below, based on Figure 1 ~ Figure 3 , a wrinkle removing device for a sheet W according to an embodiment of the present invention will be described.

[0012] The sheet W is a synthetic resin film, for example, a separator used in a lithium ion battery, and is made of polypropylene, polyethylene, or the like. The width of the sheet W is, for example, 300 mm to 500 mm.

[0013] The wrinkle removal device of the present embodiment is incorporated in a stretching system 10 that stretches a long sheet W such as an optical film while heating it in the longitudinal direction.

[0014] like figure 1 As shown, the stretching system 10 is composed of a sheet W unwinding device 12 , a longitudinal stretching device 14 , a preheating device 16 , a heating longitudinal stretching device 18 , a fixing device 20 , a cooling device 22 and a winding device 24 . The stretching system 10 stretches the sheet W in the longitudinal direction while heating the sheet W while increasing the...

Abstract

PROBLEM TO BE SOLVED: To provide a wrinkle removing device that can remove a wrinkle generated in a running web W.SOLUTION: The wrinkle removing device has a pre-heating wrinkle-removing roll 38 that is pressed to the running web W while being rotated. A rotation speed of the pre-heating wrinkle-removing roll 38 is faster than a running speed of the web W, and a temperature of the pre-heating wrinkle-removing roll 38 is higher than a temperature of the web W.

Description

technical field [0001] The invention relates to a wrinkle removing device for removing wrinkles of a strip-shaped sheet (Japanese: ウエブ). Background technique [0002] Conventionally, there has been proposed a wrinkle removing device that removes wrinkles by bringing a raw material (Japanese: 原反) into contact with a heating drum. This wrinkle removal device is a device that removes wrinkles generated on a raw material by running the raw material through a heating drum (for example, Japanese Patent Application Laid-Open No. 4-240260). [0003] Optical films are used in recent liquid crystal display devices and the like, and when producing these optical films, elongated films may be stretched in the longitudinal direction. When the film is stretched in the longitudinal direction, wrinkles may be generated in the longitudinal direction of the film. However, there is a problem that wrinkles generated on the above-mentioned film cannot be removed even if the above-mentioned wrin...
