Abstract

938,996. Moulding-machines. STONEWALLWORK Ltd. July 16, 1962 [July 19, 1961], No. 26225/61. Class 83 (1). A moulding machine comprises two diaphragms 1, 2 and provision for introducing a fluid-pressure medium such as water outside the outer diaphragm 2 to lift and support the diaphragms in an adjustable initial position, and means for introducing a fluid pressure medium such as compressed air between the two diaphragms for consolidating the moulding medium in the flask by means of the inner diaphragm 1.
