Abstract

For improving an adequate statement about the processing properties of granulated material to be added to unvulcanized rubber a testing device is used consisting of a support for the test sample, a wedge-shaped tool and a linearly acting pressure generator, whereby as support, bearing means for agglomerates are arranged on either side of the working plane of the movable wedge-shaped tool with bearing forces acting predominantly parallel thereto.
