High-speed, rotary tablet-forming apparatus wherein dies are filled with product material to be compressed on one turntable and are thereafter transferred to one or more turntables where the said product material is formed into tablets between upper and lower punches. The dies are then returned to the filling table in a closed-loop arrangement. Vacuum is introduced under empty dies on the filling turntable to facilitate rapid filling and elimination of tablet capping and laminating. Further means are provided for direct-die lubrication, eliminating the need for incorporating a lubricant into the product itself, to further enhance cohesiveness of materials being compressed and increase the life of the punches and dies involved.
