ABSTRACT:
A tablet making machine of the kind including a rotor having a die table carrying dies and opposed pairs of punches which operate in the dies, under the control of fixed position cams to form tablets in the dies is described. The rotor is carried by bearings mounted on an intermediate axially extending portion of a spindle fixed on the machine frame at its opposite ends. The rotor is made removable from the machine together with the intermediate spindle portion and the rotor bearings for replacement by a separately serviced rotor. In this fashion, downtime is reduced for tool and product changeover.
