Claims12
Method for guiding a saw blade (1) having a cutting surface, comprising disposing at least one guide stop (2) at least on one side of the blade in sliding contact with the blade at an area apart from the cutting surface to guide the blade, and forming, as a sliding surface between the blade (1) and the guide stop (2), a layer of intermediate agent (3) in a substantially solid state on a surface of the guide stop (2) which faces the blade (1) by cooling the surface of the guide stop (2) which faces the blade (1).
Apparatus for guiding a saw blade (1) having a cutting surface, said apparatus comprising at least one guide body (4) provided with at least one stop face (2) disposed against the side of the blade (1) in sliding contact with the blade at an area apart from the cutting surface, characterised in in that means for creating, as a sliding surface between the saw blade (1) and guide body (4), a layer of intermediate agent (3) in a substantially solid state on the stop face (2) is provided in conjunction with the apparatus, said means comprising elements (5,6,8) for cooling the stop face (2) from a location external to guide body (4).
