Abstract: In a process for arranging an angle scale at an index disk for rotational measurement systems, wherein the index disk is provided with a central opening for mounting on a carrier shaft, a clamping device which deforms elastically in the radial direction when the index disk is mounted on the carrier shaft is arranged in the opening, the index disk is subsequently mounted on a reference shaft and the angle scale is then arranged on the index disk so as to be exactly centered with respect to the center axis (A—A) of the reference shaft. The index disk formed in this way accordingly has a clamping device along the circumference of the central opening, which clamping device is deformed elastically in the radial direction when the index disk is mounted on the carrier shaft, contacts the outer surface of the carrier shaft accompanied by tension and, in doing so, centers the index disk in its mounted state relative to the carrier shaft.

Abstract: A length measurement system for measuring the relative position of two objects in a given measuring direction comprises a scale carrier which carries a measurement scale and which is fastened to a first of the two objects and a scanning head which scans the measurement scale at a scanning location and is fastened to the second of the two objects. The scale carrier is constructed so as to be stiff in the longitudinal direction but can deflect in a springing manner vertical to the measuring direction and is fastened by only one of its ends to the first object, while its other end projects freely. The scale carrier is positively guided in the region of the scanning head.

Abstract: An arrangement for accommodating a scale (2) of a length measuring device in a positive-locking engagement has a profile base (1) and lateral profile legs (4, 5) which are connected with the profile base so as to project away from it. A scale (2) is arranged between the profile legs (4; 5). The profile legs (4; 5) are made of elastic material and the profile base (1) is made of a longitudinally stable, bendable material. The profile legs (4; 5) can contain elastic sealing slats.

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.

Abstract: In an arrangement for fastening a length measurement device at a guide rail for a guide slide which is movable in the longitudinal direction of the guide rail and has a measurement rod and a measuring head which is movable relative to the latter, wherein the measuring head is detachably connected with the guide slide, the measurement rod is coupled directly, or indirectly in a positive engagement via a measurement rod carrier body connected with it, directly to the guide rail (1)so as to be detachable. The measurement rod or the measurement rod carrier body can be inserted by its longitudinal edges into corresponding recesses arranged at the guide rail.

Abstract: A strip-shaped, elastically flexible measurement strip for length measuring devices or angle measuring devices having a measurement scale is formed of two elastically flexible stripes which adhere to one another via a viscous intermediate film, the measurement scale being applied to one of these stripes.

Abstract: In a length measurement device for measuring the relative position of two objects in which a scale is connected with one object via retaining elements and the ruling of the scale is sensed by a sensing unit formed of a measurement head and a measurement carriage, wherein the sensing unit is coupled to the other object via a coupling point by drivers which are constructed as a deflectable, elastic coupling device. The coupling device is fastened to the measurement carriage at two connection locations, wherein the coupling point is arranged between these connection locations for coupling the sensing unit to the other object.
