Abstract
A rotary tablet press has upper rams (18) and lower rams (19) which are sealed off from the mould shelf (15) of the press by respective intermediate walls (28) in which all the rams (18,19 respectively) are clamped at their head ends to the free ends of individual sleeves (45), with the other ends of these sleeves being secured to the edges (44) of circular apertures (43) formed in the intermediate walls. These circular apertures (43) surrounding the ram shanks (20) with a spacing, so that the intermediate walls (28) are not stretched when the rams (18 and 19) carry out upward and downward movements.
