ABSTRACT:
A cover tape is adhered to a receiving tape which is provided with a plurality of cavities distributed for receiving components, to close the openings of the cavities. In order to measure the force required for stripping the cover tape from the receiving tape, the cover tape is bent to be at a prescribed stripping angle from a longitudinal end thereof to be stripped from the receiving tape, and the cover tape and the receiving tape are moved to be separated at the same speed from each other along loci of linear movement respectively while retaining the stripping angle. Tensile force acting on the cover tape is measured during such movement, thereby determining the force required for stripping the cover tape.
