An apparatus for sawing different kinds of materials has a supporting frame including a girder-type construction defining an opening for the feed-through of materials to be cut in longitudinal direction by a saw blade. A supporting platform for materials to be cut includes a carriage platform for materials to be cut includes a carriage displaceable in longitudinal direction, and a clamping arrangement for materials to be cut is located on the carriage. At least one supporting bracket is positioned laterally of the saw blade in front and back regions of the frame and mounted on said carriage, and an upper and lower cross-beam is provided for each supporting bracket, with each lower cross-beam being arranged at a distance from the carrier. Vertically movable rods are arranged between the upper and lower cross-beams and carry a clamping device for materials to be cut. The saw blades may be slanted for increased efficiency and durability.
