Test device for determining block strength by dispersions, varnishes, bandage devices etc. has contact pressure device for setting constant contact pressure to fitted elements

摘要

Two contact plates (1,15) for accommodating at least two flat elements (10) and at least a contact pressure device (16) for setting a constant contact pressure to the fitted elements (10). A contact pressure device is formed as a spiral spring (16). A measurement scale (18) is arranged with the contact plate (15) for measuring the length of the spring (16). The measurement scale (18) is a measuring tube monitoring a direction in a frame plate (2). The upper termination edge of slider (17) can serve as readout device for the measurement scale (18).
