PURPOSE:To make it possible to perform highly accurate measurement at a specified peeling angle and a specified peeling speed, by moving the tip of adhesive tape along a straight moving locus, which forms an angle that is 1/2 the peeling angle at a constant speed. CONSTITUTION:A packed product A with tape is fixed to a supporting table 10. An adhesive tape 3 is separated from the bottom and connected to an adhesive- tape supporting tool 17. With the adhesive tape 3 being tightened, the tool is set so that an adhesive-tape peeling angle theta becomes a specified value and the slant angles of the supporting table 10 and the supporting tool 17 become 1/2 the specified peeling angle theta, i.e., a tip X of the adhesive tape 3 is moved along a straight moving locus S, which forms an angle that is 1/2 the angle theta with respect to the packed product A with tape. The tip X of the adhesive tape 3 is moved along the set state like this at a constant speed. The tensile force at this time is measured. Thus the peeling strength of the adhesive tape 3 is measured. |
