Concrete layer forming machine - with light concrete feed and adjustable roller comaction for layer on three sides of heavy core

摘要

The forming machine is for production of concrete layers on constructional elements e.g. beams, window sills etc. At least one feed funnel allows light concrete (6) to be fed into the system. A set of rotatable directioning or compacting rollers (10) are mounted below each feed funnel (3'). Each compacting roller (10) is height adjustable. The roller is constructed such that a side layer of light concrete (6') is provided along the sides of the heavy concrete core (8). The heavy concrete core is coated on three sides with light concrete in this fashion.
