The device applies to earth mechanics. It can be used to determine the draw-out limits with a reduced influence of the subjective factor when reading the results. The device consists of a bundle of twisted rollers (1) spinning around their axis. One of the ends of the rollers is attached to an upper support plate (2) and the other end is connected to a bottom support plate (3) by a calibrating gap between them. Each of the support plates (2,3) is permanently fixed to a vertical stand (4). The twisted rollers (1) are connected to a driving unit (5,6) at the upper end of the stand (4).<IMAGE>
