Abstract

1432838 Lined concrete mould HUMES Ltd 22 May 1973 [25 May 1972] 24392/73 Heading B5A A reinforced concrete pipe 7 or other concrete article is formed in a hollow, rigid, outer mould member 1 that is open at opposite ends, and is lined by a flexible member 10 attached at one end to one end 12 of the mould member. The mould member 1 may be tapered, or define a bell end for moulding a pipe, and is in one piece or divided. In use, the lining 10 is inserted into the mould member 1 while inflated by pressurized air, and is attached at its one end by a clip 12. Pallets 4 and 6 close the mould member ends using clips 8 and 9. A concrete pipe is moulded centrifugally, with the mould, member axis horizontal or vertical, and the axis is then placed vertically for stripping. While the upper pallet 4 is held stationary, the mould member 1 is lifted to peel away the lining 10 from the green pipe, aided by lubrication between the lining and member 1.
