Abstract
A guide rail for an apparatus for processing concrete and rock, especially for concrete saws or for core drilling equipment, including supporting and guiding surfaces extending in the longitudinal direction, for the apparatus housing, and a profile extending parallel to the supporting and guiding surfaces and having contacting edges disposed at regular intervals from one another and extending transversely to the longitudinal direction, for an advancing mechanism provided at the processing apparatus, with the guide rail being formed of a sheet metal profile by bending an elongate, bent part, punched out of sheet metal, with the supporting and guiding surfaces and the profile for the advancing mechanism being integrated as one piece in the sheet metal profile.
