An analysis of the motion of a ball rolling on a pressure sensitive adhesive tape at a constant velocity was carried out theoretically and experimentally. In the experimental analysis, a rotary drum tack tester and a spherical probe tack tester were developed to quantitatively analyze rolling ball tack. Applying the results obtained by the two testers, actual adhesive and plowing moments and impressive moment were determined independently as a function of the rolling velocity of 11.1 mm (14/32 in.) diameter steel balls. The most important results were that the impressive force acting between the ball and the adhesive was far greater than the gravitational force due to the mass of the rolling ball and that the plowing moment played an important role in rolling resistance.
