<p>For use in manufacturing concrete building products in polyurethane moulds, a demoulding apparatus provides a clamping bar which clamps on to a lip of a mould (22) and is then moved with pivotal arms (32, 34) forward and upwardly to effectively strip the edge of the mould (22) from the front end of the respective product (24). The reciprocating mould (22) passes below a roller (66) which moves into engagement with the upper surface of the mould (22) to apply a downwardly directed pressure onto the mould and product, thereby to retain the product (24) on a conveyor (12) and rollers (68), and facilitate stripping of the mould (22) from the product (24). The stripped product (24) moves onto an offtake conveyor (70) and, in the uppermost position of the arm (32, 34), the clamping jaws are released to allow the stripped mould (22) to thereafter fall onto the conveyor (70).</p> |
