  • Patent number: 4009239
    Abstract: Chemical tablets for insertion into settling tanks and the like to dissolve solid waste material are formed in a tablet making press having a female die section which is charged with chemical in powder form. One end of an elongated strip of water soluble paper, having a heat and pressure activated adhesive coating on one surface extends between the female die and the male die carried by the press ram and is advanced in timed relation to the motion of the press. The male die section has a sharpened edge and is heated. As it moves into contact with the female die section it cuts out a separator from the sheet strip and adheres it to the tablet as it is formed. A plurality of such tablets are stacked in a cylindrical container with the separators disposed between adjacent tablets to prevent the tablets from sticking together. In use, the tablet with the separator is thrown into the settling tank and the paper separator is dissolved along with the other solid waste material.
