METHOD AND APPARATUS FOR MOULDING

摘要

In the moulding of cementitious articles, a flexible plastics mould e.g. of LDPE may be used to permit de-moulding of the articles e.g. by flexion of the mould. Moulds filled with hydraulically settable material may be supported in frames configured e.g. with plug and socket formations on upper and lower faces for cooperation with moulds to retain them in position and for cooperation with overlying and underlying frames to permit stacking.
