Title:
GUIDE ROLLER AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2013/021478
Kind Code:
A1
Abstract:
A cylindrical guide roller is provided with a first fiber-reinforced resin layer (3), a second fiber-reinforced resin layer (4) which is provided on the first layer (3), and a diamond-like carbon film (5) which is provided on the second layer (4). The orientation of the reinforcing fibers of the first layer (3) is different from the direction of the axis of the roller. The orientation of the reinforcing fibers of the second layer (4) is the same as the direction of the axis of the roller. This method for manufacturing the roller includes a step which forms a roll of a first prepreg sheet, a step which winds a second prepreg sheet on the roll, a step which heats and cures the roll, a step which adjusts the surface roughness and roundness of the surface of the roll by grinding the surface of the roll, and a step which forms a diamond-like carbon film on the surface of the roll by an ion implantation method. The second prepreg sheet is formed by impregnating an epoxy resin into a carbon fiber sheet.
