Abstract

A woodworking machine tool has a rotary cutter covered by a protective plate (6) resting on the surface of the worktable when not in operation, with a swinging arm (12a) at the front, and another (18b) at the rear which act as sensors, so that when the leading edge of an workpiece (B) contacts the first arm (12a), the plate is lifted clear, and when the leading edge contacts the second arm (12b), the plate is held down on the workpiece. these detectors actuate a spring loaded single acting valve which operates a hydraulic circuit to control the raising and lowering of the pressure plate, this plate being supported on a system of cross slides mounted to travel alongside the worktable.
