First, a sample holder (13, 57) is lowered such that a sample is held. Next, a roller (11) or a plate-shaped member (56) is lowered and pressed to an adhesive surface (15A) of a sample (15). At this time, a tape (23) is disposed between the roller (11) or the plate-shaped member (56) and the adhesive surface (15A) of the sample (15), and a fixed pressure load is applied to the sample (15). Then after a fixed period of time has passed, the tape (23) is pulled from the sample (15) by the raising of the roller (11) or the plate-shaped member (56) and an adhesive strength is measured with a load cell (25) according to the tension of the tape (23) at that time. After measuring, a take-up reel (21, 52) is rotated so as to wind up a predetermined pitch of the tape (23), and an unused portion of the tape (23) is reeled out to the tip of the roller (11) or the plate-shaped member (56).
L'invention concerne un procédé permettant de mesurer une force d'adhésion, qui comprend les étapes suivantes : abaisser les éléments de retenue (13,57) d'échantillons, de manière à comprimer un échantillon ; abaisser un rouleau (11) ou un élément lamellaire (56) de manière à agir par pression contre la surface adhésive (15A) de l'échantillon (15), un ruban (23) étant placé entre le rouleau (11) ou l'élément lamellaire (56) et la surface adhésive (15A) de l'échantillon (15) et une charge de compression déterminée à appliquer à l'échantillon (15) ; relever le rouleau (11) ou l'élément lamellaire (56) après un temps déterminé écoulé, de manière à entraîner le ruban hors de l'échantillon (15) afin de mesurer une force de séparation par une cellule de charge (25) utilisant la tension dudit ruban (23), et enrouler le ruban (23) à cet instant par un écartement angulaire déterminé après la mesure, par rotation des bobines (21,52), de sorte à relâcher la partie non utilisée du ruban (23) en direction de l'extrémité du rouleau (11) ou de l'élément lamellaire (56).
