Arrangement for determining the relative position of two bodies that are movable in relation to each other, and process for producing such an arrangement
First Claim
1. An arrangement for determining the relative position of two bodies movable in relation to each other, comprising:
- a first body;
a second body movable relative to the first body;
a separate measuring tape applied to the first body and having a longitudinal direction;
the measuring tape having at least one track of measuring markings which are distributed along the tape in said longitudinal direction;
a sensor carried by the second body for movement along the track of measuring markings in the course of relative movement between the two bodies, the sensor being responsive to the measuring markings; and
the measuring tape being attached to the first body at at least two attachment points, which attachments points are arranged at a distance from each other in the longitudinal direction of the tape, and being elastically stretched between the attachment points in the longitudinal direction of the tape.

Abstract
In an arrangement for determining the relative position of two bodies (3, 7) that are movable relative to each other, a separate measuring tape (29) is attached to a first (3) of the two bodies (3, 7). The measuring tape includes at least one track of measuring markings, distributed in the longitudinal direction of the tape. The second (7) of the two bodies (3, 7) carries a sensor arrangement (31) which responds to the measuring markings and travels along the track, in the course of relative movement between the two bodies (3, 7). The measuring tape (29) is attached to the first body (3), at at least two attachment points that are arranged at a distance from each other in the longitudinal direction of the tape, and is elastically stretched between the attachment points in the longitudinal direction of the tape.

20. An arrangement for determining the relative position of two bodies movable in relation to each other, comprising:
-
a first body, the first body carrying measuring markings which are distributed over a marking range;
a second body, the second body movable relative to the first body and carrying a sensor which responds to the measuring markings upon traveling thereover in the course of relative movement between the two bodies;
a cover tape which is separate from the first body and which covers the measuring markings, the cover tape having a flat side that is directed towards supporting surfaces on the first body, the cover tape being attached to the first body along each of the two longitudinally extending edges of the cover tape by at least one longitudinal welding seam; and
the longitudinal welding seams running at a distance, in the direction crosswise to the longitudinal direction of the tape, from the respectively adjacent longitudinal edge of the cover tape and forming, in the region of the supporting surfaces, a material fusing zone of the cover tape with the first body. - View Dependent Claims (21, 22, 23, 24, 25, 28, 29, 30)

26. A process for the production of an arrangement for determining the relative position of two bodies which are movable in relation to each other, wherein a first of the two bodies carries measuring markings which are distributed over a marking range and the second of the two bodies carries a sensor arrangement which responds to the measuring marking and travels over the marking range in the course of relative movement between the two bodies, said process comprising:
-
covering the measuring markings by a cover tape which is separate from the first body and which is laid with a flat side thereof upon supporting surfaces of the first body; and
attaching the cover tape to the first body along each of the two longitudinal edges of the tape by means of at least one longitudinal welding seam, said longitudinal welding seams being applied at a distance, in the direction crosswise to the longitudinal direction of the tape, from the respectively adjacent longitudinal edge of the unwelded cover tape in a manner such that said seams cause a material fusing of the cover tape with the first body in the region of the supporting surfaces.

27. A process for the production-of an arrangement for the determination of the relative position of two bodies that are movable in relation to each other, wherein a first of the two bodies carries measuring markings that are distributed over a marking range and the second of the two bodies carries a sensor arrangement which responds to the measuring marking and travels over the marking range in the course of relative movement between the two bodies, said process comprising:
-
covering the measuring markings by a cover tape which is separate from the first body; and
attaching the cover tape to the first body along each of the longitudinal edges of the cover tape by at least one longitudinal welding seam adjacent to the respective longitudinal edges of the cover tape, said two longitudinal welding seams being applied essentially simultaneously.

31. A process for the application of a measuring tape to a separate carrier, comprising attaching the measuring tape to the carrier at at least two attachment points which are arranged at a distance from each other in the longitudinal direction of the tape, the measuring tape being under elastic stretching between the attachment points.
