Definitions
- the invention relates to a method for producing a ski edge prepared for installation in a ski from rolled and tempered material, which on their
- ski edges For the production of ski edges, a steel strip profile is first rolled according to the prior art, which is then hardened and tempered, i.e. is remunerated. In order to avoid signs of corrosion due to oxidation (rust) during transport and storage of these ski edge strip profiles, which are marketed as semi-finished metal products, they are coated with anti-corrosion oil. If necessary, recesses and / or openings are punched into the flank of the strip profile beforehand or subsequently.
- the further processing of the ski edges usually takes place at the ski manufacturer.
- the corrosion protection oil serving as corrosion protection is removed there.
- the ski edge band profile is then sandblasted in order to mechanically detach the oxide skins formed.
- the edge of the ski is coated with a primer coated, embedded in the plastic body of the ski and glued.
- a major disadvantage of this known method for the production of a ski edge is that the ski edge strip material supplied to the ski manufacturer as a semi-finished product has to be prepared with a relatively large production expenditure before it is installed in the ski.
- the removal of corrosion layers, ie the oxide skin, by means of sandblasting or the like, as well as the use of solvents for removing the anti-corrosion oil means a relatively high expenditure of work, time and costs.
- the use of solvents as a rule chlorine-hydrocarbons, is particularly harmful to the environment, both with regard to solvent vapors escaping in the production process and with the disposal of the solvent contaminated with corrosion protection oil.
- the invention proposes that the ski edge tape material be coated with the adhesion promoter (primer) in a continuous operation following the remuneration, at least in the area of the adhesive surfaces, the ski edge tape material being coated immediately before coating reducing conditions is maintained that the surface of the strip material is free of oxide before coating.
- the time-consuming and labor-intensive mechanical removal of oxide skins is completely eliminated.
- Another advantage results from the fact that the primer coating applied to the bare metal serves simultaneously as a corrosion protection layer.
- the application of corrosion protection oil or the like to the ski edge band profile before storage and transport to the ski manufacturer is unnecessary. Accordingly, the laborious, time-consuming and environmentally harmful degreasing of the strip material is also eliminated.
- the primer coating adheres particularly firmly and evenly to the ski edge strip profile in the process according to the invention, because neither corrosion protection oil residues nor corrosion residues impair the homogeneity of the material surface in this process.
- the connection of ski edge band profiles produced by the method according to the invention to a ski body particularly strong and reliable, which makes them particularly suitable for use in the manufacture of snowboards and monoski or other skis that are heavily loaded on the edge - e.g. 3. Slalom ski - are suitable.
- the adhesive used can be easily adapted to the ski edge material and the material of the ski base body, usually PU foam or epoxy laminate.
- the layer thickness of the primer applied to the ski edge can be predefined in a defined manner using the method according to the invention. This results in the possibility of making the primer layer sufficiently thick so that the adhesive joint is sealed. This reliably prevents the penetration of moisture through the adhesive joint into the ski body. Damage caused by condensation can thus be largely ruled out and the durability of ski bodies made of PU foam, for example, is significantly extended.
- the tempering of the ski edge strip material takes place under a reducing atmosphere.
- the ban profile is heated to temperature. heated below the structural transformation temperature. If it is passed through a reducing gas atmosphere - for example an H2 ⁇ N2 mixture - no oxide can form and even slight oxide residues on the surface are removed by the reduction process. After that, the surface is practically oxide-free.
- the ski edge strip material is passed through a reducing pickling bath after hardening and tempering.
- oxide-free surfaces are obtained since a reduction process also takes place on the surface.
- a continuous pickling bath can easily be integrated into existing production systems.
- ski edge tape material is provided with punched-out areas after the adhesion promoter (primer) has been applied.
- Such punchings are used to firmly anchor the ski edge in the ski body and are usually stamped into a flank of the band profile by means of suitable tools.
- the adhesive coating acts as a lubricant.
- ski edge tape material is stripped in a pickling bath before being coated with the adhesion promoter.
- the advantages of the method according to the invention can also be transferred to ski edge materials which are difficult to handle. For example, scaling that occasionally occurs during hardening is removed without residue.
- the ski edge tape material For special applications, it can prove to be advantageous to roughen the ski edge tape material at least on the adhesive surfaces before coating with the adhesion promoter (primer).
- the surface of the adhesive surface is defined roughened or structured by sand or pearl blasting or other methods.
- the surface area enlarged in this way contributes to the fact that on the one hand the primer adheres even more firmly to the ski edge tape material and on the other hand the anchoring of the ski edge in the ski is also improved by means of the adhesive bond.
- An advantageous technical embodiment of the process according to the invention provides that the process steps take place under an inert gas atmosphere (H2-2) before the ski edge strip material is coated with the adhesion promoter. This measure reliably reduces any oxidation during the manufacturing process. Such a configuration is possible with the modern continuous remuneration systems used.
- FIG. 1 schematically shows a device for carrying out the method according to the invention
- FIG. 2 shows a ski edge band profile coated with an adhesion promoter (primer);
- FIG. 3 schematically shows a device for carrying out the method according to the invention in a second embodiment.
- a continuous production plant for ski edge band profile is shown schematically.
- a profile rolling mill with a connected hardening furnace are simply summarized in a block and provided with the reference number 1.
- the outlet of the hardening furnace 1 emerges in the direction of the arrow, i.e. from left to right, bare, oxide-free ski edge tape profile 2.
- a primer coating system which is provided with the reference number 3 as a whole.
- the ski belt profile 2 emerging from the hardening furnace 1 enters the coating system 3 and is guided over a coating roller 4 therein.
- a primer layer 5 is applied to the edge strip profile 2.
- the ski edge belt profile 2 passes through a temperature-controlled drying chamber 6, in which the primer layer 5 hardens.
- the ski edge strip profile 2 is kept under a reducing gas atmosphere, for example H2-N2, up to just before the coating roller 4. This is not emphasized in detail in the drawing.
- the reducing gas atmosphere is implemented in practice by flooding the passage area of the ski edge strip profile 2 with reducing gas.
- ski edge band profile 2 emerging from the primer coating system 3 to the right in the illustration and provided with the primer layer 5 is now ready for further processing and can optionally be wound onto a winding reel (not shown).
- FIG. 2 shows a section of the ski edge strip profile 2 coated by means of the primer coating system 3 from FIG. 1.
- the primer coating 5 covers the adhesive surface of the ski edge tape profile 2 and is shown hatched.
- FIG. 3 shows a second embodiment of a primer coating system in the same representation as in FIG. 1 and provided with the reference number 7. there the same reference numerals as in FIG. 1 are used for identical components.
- the ski edge strip profile in the primer coating system 7 passes through a reducing continuous pickling bath 8, which is arranged in front of the coating roller 4 in the running direction.
- the continuous pickling bath 8 is filled with pickling and neutralizing agents known per se.
- the primer coating system 7 can be flushed with inert gas in order to effectively prevent oxidation after the pickling in the continuous pickling bath 8.
- the ski edge band profile 2 produced according to the method of the invention and provided with a primer layer 5 can now be glued into a ski body, for example by a ski manufacturer.
- the primer coating 5 adheres particularly firmly to the ski edge band profile 2 and at the same time serves as corrosion protection. Further processing of the material surface before installation in the ski is therefore no longer necessary.
