Abstract

892,794. Moulding curved concrete or resin articles. MATTHEWS, G., and MATTHEWS, D. E. Sept. 30, 1959 [April 2, 1959], No. 11250/59. Class 87(2). A fluid moulding material, e.g. a synthetic resin or concrete, is placed on a flexible sheet 1, covered by another flexible sheet 5, the two sheets anchored at their perimeter by a clamp 3 to a base 2, and the sheets distended by fluid pressure to mould the material into a dome. In a modification, Fig. 5, a tube of bulged cross-section is formed using a mandrel 8 and flexible tubes 7, 11.
