PCT No. PCT/GB94/02308 Sec. 371 Date Jul. 29, 1996 Sec. 102(e) Date Jul. 29, 1996 PCT Filed Oct. 20, 1994 PCT Pub. No. WO95/11119 PCT Pub. Date Apr. 27, 1995For use in manufacturing concreted building products in polyurethane molds, a demolding apparatus provides a clamping bar which clamps on to a lip of a mold (22) and is then moved with pivotal arms (32,34) forward and upwardly to effectively strip the edge of the mold (22) form the front end of the respective product (24). The reciprocating mold (22) passes below a roller (66) which moves into engagement with the upper surface of the mold (22) to apply a downwardly directed pressure onto the mold and product, thereby to retain the product (24) on a conveyor (12) and rollers (68), and facilitate stripping of the mold (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 mold (22) to thereafter fall onto the conveyor (70). |
