Abstract
An evaluation subject formed by a cut sample of a conveyor belt is mounted on a flat substrate with an inner periphery-side cover rubber layer located on the upper side, a support roller mounted in a frame is horizontally pulled and rolled in the longitudinal direction of the evaluation subject by pulling the frame by a wire while the support roller is pressed vertically downward against the upper surface of the evaluation subject at a preset pressure using a pneumatic cylinder without substantial deformation of the outer peripheral surface thereof, and tensile force in a horizontal direction measured at this time by a tensile force sensor connected to the wire is evaluated as resistance to moving over the support roller.
