Abstract
A ski has better guide properties the sharper the corner areas of the steel edge profiles. Using a laser beam, the corner areas of the steel edge profiles are hardened on the ski.
Claims33
Apparatus for treating the steel edges of skis and other runner devices that have a runner base top layer with a first outer surface, two steel edge profiles mounted on two longitudinal edges of the runner base top layer, each with a second outer surface facing downwards when in use and a third outer surface facing laterally and forming a corner edge area with said second outer surface, comprising:
- a) leveling means for leveling the heights of the first and second outer surfaces if they are not level relative to each other,
- b) laser beam means having a point of incidence for bringing at least the corner edge area to the hardening temperature of the steel edge profile,
- c) means for moving the laser beam and runner device relative to each other in the longitudinal direction of the steel edge profile, and
- d) means for drawing off heat to prevent detrimental heating up of the volume of the runner device around the steel edge profile in the area of the point of incidence of the laser beam.
