Abstract
A wiper apparatus for sweeping or clearing debris from a surface, such as cuttings generated in a machining operation that have collected on a collecting surface, comprises rotatable wiper arms and dependent wiper blades. The wiper apparatus can be self-powered or it can be driven by a screw mechanism that engages the wiper arms, causing the wiper arms to rotate. The wipers are capable of relative movement in relation to the wiper arms, and the wipers may be rigid or flexible. Springs can be used to mount the wipers to the wiper arms. According to one embodiment, the wiper apparatus comprises a central portion including a hub to which the wiper arms are secured and a base adapted to be secured to the collecting surface. The hub is rotatably mounted to the base.
