发明名称 Roadway grooving apparatus
摘要 A machine for cutting transverse grooves in a concrete road surface includes a rotary cutter head supported on a carriage that can be shifted longitudinally along the machine frame structure. By using a combination of motions of the frame structure and cutter head carriage it is possible to form grooves spanning substantially the entire distance from one curb to the other curb during a single pass of the machine.
