Abstract: A simulation device for the screw joint simulation of a nutrunner includes a test connecting element rigidly connected to a brake unit. The nutrunner can be coupled to the test connecting element and activated to exert a torque that rotates the test connecting element about an axis of rotation. Activation of the brake unit brakes the test connecting element. A torque transducer includes a rotational angle transducer for measuring a rotational angle by which the test connecting element rotates about the rotation axis. The simulation device includes a zero mark, and the brake unit can be adjusted to a zero angle with respect to the zero mark.

Abstract: A knife holder 1 for a cutting knife 2 of a microtome for cutting samples is described. Knife holder 1 has a pressure plate 3 for locking the cutting knife in the knife holder and for discharging the cut sample. A U-shaped frame 4, open toward edge 5 of cutting knife 2, is associated with pressure plate 3.

Abstract: A bearer strip having components arranged in several parallel rows with variable spacing between the rows so as to increase packing density while providing sufficient empty space for introducing free flowing plastic on the bearer strip.

Abstract: A paper web impregnated with a liquid resin and following impregnation is coated with an abrasive particle containing coating mass or composition and then dried before a liquid resin is applied which does not contain the abrasive particles. The web is then finally dried and the resulting paper is particularly suitable as a cover sheet in the hot pressing of laminates since it minimizes wear of the laminate press.

Abstract: The sailing and floating of the sheets which has occurred uncontrollably at certain speeds is avoided so that an exact stacking is permitted at high speeds. The vacuum conveyor is a vacuum belt conveyor whose vacuum box with circulating vacuum belts extends over the entire stacking location and the brake device. The brake device comprises an upper circulating belt supported by a vacuum chamber whose upper strand reaches up to the stacking location. Thus the sheets during the stacking process are guided precisely and do not float freely.
