Abstract
A machine for casting concrete panels. The machine disclosed casts hollow core concrete panels in a single casting operation utilizing a slipform technique to fill cores with core material which can be dumped from the core after curing of the concrete has been accomplished. Vibration of the slipform during casting facilitates free flow of concrete around the slipform and core material extruded from slipforms. The slipfom has a closed front portion which is tapered to a reduced cross section. The machine utilizes a casting pallet employing improved side form cleaning apparatus. The machine also includes improved finishing screeds for applying decorative three-dimensional finishes on the top surface of cast panels.
