ABSTRACT:
A conveyor table is provided on a floor mounted support frame and a pair of tool guides are disposed horizontally and laterally above and below the conveyor table. Several readily removable tool and cutter assemblies, each having a freely rotatable, circular blade with teeth, are slidably mounted on the tool guides. Setscrews are provided on the tool and cutter assemblies to secure them on the tool guides in relatively opposing, vertically aligned pairs. Electrically powered drive units are disposed upstream and downstream of the tool and cutter assemblies to engage a sheet of wallboard, hold it against the conveyor table and move it between the opposing pairs of tool and cutter assemblies.
