ABSTRACT:
Apparatus for use in the adhesion measurement of an adhesive sheet comprising a standard surface to be sticked with a main portion of the adhesive sheet, a take-up roller for pulling and taking up the free end portion of the sheet while peeling the sticked sheet portion from the standard surface by the rotation thereof, a source of driving force for rotating the take-up roller, and a torque meter interposed between the source of driving force and the take-up roller for generating torque signals corresponding to the adhesion of the adhesive sheet. The apparatus further includes: a base table extending in parallel with the standard surface; and track rolling members operatively connected to the take-up roller and mounted to a machine frame supporting the take-up roller, the torque meter and the source of driving force, and the rolling members being adapted to roll on the standard surface at the same speed with the peripheral speeed of the take-up roller.
