<p>Abstract Rotary tablet making machine Compression station (6) of the machine (1) comprises a stationary bottom actuator circular disc (13) disposed in the path of the lower punches of the machine in the radial direction of the bottom actuator disc and having a first flat surface (15) at the top most circumference thereof and a stationary top actuator circular disc (16) disposed vertically aligned with the bottom actuator disc in the path of the upper punches of the machine in the radial direction of the top actuator disc and having a second flat surface (18) at the bottom most circumference thereof matching with and aligned with the first flat surface at the top most circumference of the bottom actuator disc. An endless roller chain (19) is rotatably mounted over the respective actuator disc. A roller chain consists of a plurality of compression segments (20). Each compression segment has a flat outer face (22) corresponding to and matching with the first and second flat surfaces at the outer circumference of the respective actuator disc and a roller (25) rotatably held at the inner face of the compression segment making a line contact with the outer circumference of the respective actuator disc. Punch heads (10a, 9a) of the lower and upper punches engage against the flat outer faces of the respective roller chain (Fig 5).</p> |
