摘要
Plant comprising a rotary drum with a horizontal rotary axis lined, over its outer cylindrical surface with molding means and adapted to pass said molding means during rotation, before various working stations such as concreting, hardening, stripping and core positioning stations. The drum is equipped with beams with a composite profile fixed, notably by welding, longitudinally on the outer periphery of the drum. The beams have a cross-section which has zones adapted to form a roller track parallel to the longitudinal axis of the drum for the rolling and guidance of compacting means for the concrete. It is equipped with fastening means for the molds in a position situated radially outwards with respect to said roller track. It also has sufficient mechanical strength to absorb the major part of the prestressing forces exerted on the cores in the case of manufacturing prestressed concrete elements.
