(54)	Process for producing a plate-like prefabricated member

(57) For producing a plate-like prefabricated member (200), concrete is lead into a discharging apparatus, comprising a container (14), a closure (18) and a vibrator (26) attached to the closure (18) such that the material leaving the container and the material discharged into the mould (50) is vibrated. A layer of concrete is cast in a mould (50) and the casting is subsequently dried. By using a casting template (300), webs (206) which form channels (208,210) therebetween can also be performed according to this process .
