Device for testing of tablets, comprising a test chamber, featuring a crushing jaw and a counter jaw opposite it, whereby - a conveyer is arranged to position the tablets to be tested into the test chamber and pushing the tablet material back from the test chamber after testing, and the conveyor consisting of a pivoted round base body, from which several driver arms extending in a radial direction, whereby - the device featuring a computer system, controlling the motion sequences in such a way that one driver arm pushing the tablet into the test chamber, while one adjacent driver arm pushing the tablet material from the test chamber at the same time, and - the distance of the driver arms at the passage to the base body basically corresponds to the breadth of the crushing jaw and the lateral boundary of the test chamber are each respectively formed by two adjacent driver arms in the testing position, and - the device being arranged in such a way that moving the tablets to be tested as well as the tablet material takes place through a rotation movement of the driver, characterised in that - the device featuring a movable sheet metal arranged to position a tablet for testing and - the longitudinal axis of the moving sheet metal strip is oriented at an angle of less than 90 °C to the longitudinal axis of the direction of movement of the breaking jaw and the direction of movement of the metal strip corresponding to the longitudinal axis of the sheet metal strip, - the computer system still controlling the motion sequences in such a way that the conveyer is turned in the direction of rotation from the tablet to the test chamber until the side, situated in front and in direction of rotation of the tablet pushed by the driving arm in direction of rotation, in such a way that the tablet is at least partly situated outside of the test chamber, and - the conveyer subsequently turned in the opposite direction so far until the tablet is finally fully positioned inside the test chamber again. - a conveyer is arranged to position the tablets to be tested into the test chamber and pushing the tablet material back from the test chamber after testing, and the conveyor consisting of a pivoted round base body, from which several driver arms extending in a radial direction, whereby - the device featuring a computer system, controlling the motion sequences in such a way that one driver arm pushing the tablet into the test chamber, while one adjacent driver arm pushing the tablet material from the test chamber at the same time, and - the distance of the driver arms at the passage to the base body basically corresponds to the breadth of the crushing jaw and the lateral boundary of the test chamber are each respectively formed by two adjacent driver arms in the testing position, and - the device being arranged in such a way that moving the tablets to be tested as well as the tablet material takes place through a rotation movement of the driver, - the device featuring a movable sheet metal arranged to position a tablet for testing and - the longitudinal axis of the moving sheet metal strip is oriented at an angle of less than 90 °C to the longitudinal axis of the direction of movement of the breaking jaw and the direction of movement of the metal strip corresponding to the longitudinal axis of the sheet metal strip, - the computer system still controlling the motion sequences in such a way that the conveyer is turned in the direction of rotation from the tablet to the test chamber until the side, situated in front and in direction of rotation of the tablet pushed by the driving arm in direction of rotation, in such a way that the tablet is at least partly situated outside of the test chamber, and - the conveyer subsequently turned in the opposite direction so far until the tablet is finally fully positioned inside the test chamber again.
