摘要

APPARATUS AND METHOD FOR MANUFACTURING ARTICLES FROM CHALK OR THE LIKE AN APPARATUS AND METHOD FOR MANUFACTURING PIECES OF TAILOR'S CHALK IS DISCLOSED. THE INGREDIENTS OF THE CHALK ARE FORMED INTO A PLURALITY OF PELLETS (51). THESE PELLETS ARE LOADED INTO A HOUSING (1). A HELICAL MEMBER (11) MOVES THE PELLETS ALONG THE HOUSING TOWARDS THE OUTLET (5). A CYLINDRICAL FLUID CONTAINER (23) 10 RECEIVES A CONTINUOUS SUPPLY OF COLD WATER WHICH COOLS THE MATERIAL IN THE HOUSING. ANOTHER CYLINDRICAL FLUID CONTAINER (25) ALSO CONTAINS WATER. THE WATER IN THIS CONTAINER IS MAINTAINED AT A STABLE TEMPERATURE EQUIVALENT TO THE HEAT GENERATED BY THE ROTATION OF THE HELICAL MEMBER. THE MATERIAL IN THE HOUSING I NEXT PASSES TO A HEATER (27) WHICH MELTS THE MATERIAL SO THAT IT CAN BE FORMED 15 INTO PIECES OF TAILOR'S CHALK BY INJECTION MOULDING (35 - 41).
