Abstract
881,777. Feeding moulding material to moulds. NOKEL, W., and SCHRADER, H. May 29, 1959, [July 5, 1958] No. 18338/59. Class 87(2). [Also in Groups XXII and XXX] The lining member 7 of a machine for blowing moulding material into boxes e.g. when making ceramic or masonry mouldings, is made of an air-permeable porous material such as sintered metal, porous plastics, ceramic or ceramic made particularly porous by means of gas formers or burning-out materials. The porosity may be different in parts of the member, by using different wall thicknesses or materials with varying porosity.
