ABSTRACT:
A process for measuring the adhesive power of pressure-sensitive adhesives, especially adhesive tapes or sheets; it is also related to a device for implementing this process. This process consists in causing a ball to fall freely onto the adhesive surface of the tape or sheet and exerting a vertical upwardly directed separating force upon the ball, the measurement of the adhesive power of the adhesive being a function of the time comprised between the instant when the separating force is initially exerted upon the ball and the instant when the ball returns to its initial starting point.
