Abstract: In a process for edging metal strips, especially nonferrous metal strips, by means of an edging machine wherein the longitudinally driven metal strip is guided between an upper and a lower linear guide and cutting tools are disposed successively along the line of movement of the strip, on either side of the linear guides. It is proposed according to the invention that a liquid or gaseous fluid be forced out of the central part of the linear guides at individual points along the line of movement, into the clearance between the metal strip and the linear guides. In a linear guide for carrying out this process, provision is made according to the invention such that, in each linear guide face confronting the metal strip, there are a series of grooves running longitudinally along the center of the guide, the grooves being separate from one another and connected to inlets for the fluid.

Abstract: Chip remover for machines which perform a machining operation, especially on metallic workpieces, such as strip edging machines, turning machines, etc. The chip remover has a stretched spiral rotating about its longitudinal axis with successive turns spaced apart from one another. The free upper end of the spiral extends into the chip discharge area of the machining tool. This spiral carries the chips away from the area about the tool to assure unhampered machining. The spiral is in the form of a hollow helix and is surrounded, on the outside, with only minimal clearance, by a non-rotating guide tube having an open-topped slot running lengthwise of the tube. The upper end of the helix extends freely out of the tube.
