Abstract
A rotary tablet press, with a rotor driven by a driving motor, which has a die plate as well as an upper and a lower guiding for upper and lower punches, which co-operate with bores of the die plate, a stationary housing closely surrounding the rotor, which constitutes a pressing room, and with at least one ring-shaped sealing arrangement, which seals the housing against a punch guiding, wherein the sealing arrangement has a ring-shaped holder inside the housing, wherein the ring-shaped holder is axially movable between a first and a second position by means of a stationarily arranged lifting device, the sealing arrangement has a first sealing portion, which is continuously in engagement with a first sealing surface of the housing in the first and in the second position, and a second sealing portion which is in engagement with a second sealing surface of the punch guiding with a first sealing force in the first position and is in engagement with the second sealing surface in the second position either with a second sealing force, which is smaller than the first sealing force, or is out of engagement with the same.
