A rotary tablet press is provided for the manufacture of water soluble tablets by compression of powdered tablet material which does not include hydrophobic lubricants such as magnesium stearate. The tablet press includes a plurality of dies rotatable around a central axis of the press, and upper and lower punches which are rotatable with the dies and slidably mounted for compressive engagement with the dies. A feeder is provided for introducing the powder tablet material through a feed frame and into the dies. The feed frame includes a cam surface for removing the completed tablets from the dies. A brush is rigidly fastened to the feed frame and adapted to engage the working faces of the upper and lower punches to remove tablet material buildup therefrom after each of the punches has released the tablets. The brush is fabricated from food grade materials and includes bristles which extend obliquely relative to the faces of the upper and lower punches. |
