Patent ID: 6862911

Claim:
A method for cutting a hollow extruded profile section into lengths in a press flow, wherein the extruded profile section, after discharge from a press, is bent simultaneously with or immediately after the forming extrusion process by a force acting on the extruded profile section at right angles to the extrusion direction, one component of the force acting as a tensile or compressive force on the cross-sectional face of the hollow profile section walls during the forming extrusion process, the method comprising the steps of: cutting the extruded profile section into lengths in the press flow by the mechanical action of a saw, and supporting the extruded profile section on a support means during cutting to prevent deformation of the extruded profile resulting from the force exerted on the extruded profile section while it is being cut into lengths, such deformation being prevented by the support means bearing on the extruded profile section during cutting, the extruded profile section being made of an aluminum alloy or a magnesium alloy and having a temperature in the range of 200° C. to 600° C. while it is being cut into lengths.
