摘要： A tablet coating machine for applying a coating to a bed of tablets, the machine comprising a circular drum (5) with frusto-conical ends which is rotated about its axis by suitable means. The periphery of the drum is perforated to allow air to flow through the bed of tablets disposed in the drum. In order to be able to optimise the efficiency of the tablet coating process for different quantities of tablets, the volumetric capacity of the drum is adjustable to achieve a desired tablet depth for the quantity of tablets being processed. More particularly an axially adjustable wall portion (31) is provided within the drum to adjust the length of the tablet containing portion of the drum. The area over which air is sucked from the drum by a suction shoe applied to the periphery thereof is adjustable to tailor it to the length of the tablet containing portion of the drum.

摘要： A rotary tabletting press for the production of tablets comprising a turret driven rotatably and carrying with it a die plate (7; 106) accommodating a plurality of die cavities (9; 114) each comprising a through bore having upper and lower openings. Respective pairs of upper and lower punches (31, 33; 110, 120) to work in each die cavity and wherein tabletting material which enters the die cavities by the upper opening is enclosed within a chamber (19; 122), disposed above the die plate. Means to control closing of the die cavities comprises a fixed scraper blade (25; 228) disposed adjacent the upper surface of the die plate and intercepting the path of the die cavities. The turret comprises axially separable upper and lower parts and the chamber is defined between the upper and lower parts. Also described is a die clamping system whereby a plurality of dies (116) accommodating a respective die cavity are simultaneously located in position. A common die clamping element (150) is used which is located axially when the upper housing part (100) is in its operating position. A shouldered die is employed.
