Abstract

For directed mounting of a measurement strip in a length measuring system in which two bodies are arranged so as to be displaceable relative to one another, lateral mounting elements are fastened along the length of the measurement strip at a machine part against which the measurement strip is mounted before the measurement strip is fastened to this body.

Claims

1. A method for directed mounting of a measurement strip in a length measuring system comprising the steps of:

providing a first body at which the measurement strip is mounted and a second body which is displaceable relative to the first body;

arranging a mounting device at the movable second body;

fastening mounting elements by means of said mounting device in alignment with a movement path of the second body at the first body before the measurement strip is fastened to the first body; and

mounting the measurement strip along said mounting elements.

2. The method according to claim 1, wherein the mounting elements are arranged in such a way that the measurement scale can be inserted therebetween in a positive engagement and so as to be retainable.

3. The method according to claim 1, wherein the mounting elements are at least one of being self-adhesive and being provided with a protective strip.

4. The method according to claim 3, wherein the protective strips of the mounting elements are pulled off before fastening to the receiving surface.

5. The method according to claim 1, wherein the measurement strip is glued in between the mounting elements.

6. The method according to claim 1, wherein the measurement strip is fastened by an adhesive foil.

7. The method according to claim 1, wherein the measurement strip is fastened by means of a viscous adhesive film.

8. The method according to claim 1, wherein the mounting elements are individual partial mounting elements arranged one after another in the moving path of the second body and the individual mounting elements are arranged in one method step, and wherein the individual mounting elements are interrupted at least at joint locations of the partial mounting elements and wherein the measurement step is mounted along the mounting elements in a continuous manner after mounting of the individual partial mounting elements.

9. A device for directed mounting of a measurement strip of a length measuring system on a first body, comprising:

a second body which is displaceable relative to the first body;

a mounting device at the movable second body; and

mounting elements on the first body which are fastened by the mounting device in alignment with a movement path of the second body, whereby the measuring strip is to align by the fastened mounting elements.

10. The mounting device according to claim 9, wherein the mounting elements have guide channels for guiding the measuring strip.

11. The mounting device according to claim 9, wherein means are provided for applying contact pressure to the mounting elements.

12. The device according to claim 9, wherein said mounting elements have adhesive protective foils and wherein means are provided for pulling off adhesive protective foils of the mounting elements.
