Abstract
A method and device allow automatic trimming of samples for the measurement of the rheological properties of material samples by way of a plate/plate rheometer. In order to strip the protruding portion of the material sample arranged between the plates that projects over the circular circumferential edges of the rheometer plates—a cutting edge, which at its setting angle with respect to the tangent is pressed against the circular circumferential edge of the plates at the line of contact and pertains to the blade of the stripping tool that is stayed, in particular articulated, by means of a holding strut at a holding point of a holding block, and the plates of the rheometer —relative to each other—are moved in rotation in a circle with respect to each other in at least a fully circumferential circular rotational movement, wherein the circular rotational movement is guided in such a way that the real or virtual relative rotational advance of the cutting edge of the stripping-tool blade is effected counter to the virtual or real circumferential circular rotational advance respectively of the rheometer plates.
