Title:
CONTACT ROLL, FILM WINDING DEVICE, AND MANUFACTURING METHOD FOR FILM ROLL
Document Type and Number:
Japanese Patent JP2023111872
Kind Code:
A
Abstract:
To provide a contact roll capable of sufficiently reducing wrinkles and electrostatic charges of a film roll over a long period, even in manufacturing a film roll having high surface smoothness.SOLUTION: A contact roll has a first layer made of an elastic body on a core material, and a second layer that is the outermost layer on the outside of the first layer, where a static friction coefficient μ0 of the surface of the second layer is more than 0.20 and 0.30 or less, and a volume resistivity ρ of the second layer is 1.0×103 Ωcm or more and 1.0×108 Ωcm or less.SELECTED DRAWING: Figure 2
