## Abstract

The device 1 for positioning the measuring element of a measuring apparatus comprises a traverse 14 on which the measuring element is arranged. The device further comprises a track 11 on which bearings 12, 13 run, and on which the traverse 14 is held by means of bearings 124, 125. The measuring element of the measuring apparatus can be positioned radially in relation to the track 11 and along the track 11. The traverse 14 comprises multiple components, wherein the components 141, 142 of the traverse 14 are interconnected with one or several bearings 143, or the components 141, 142 of the traverse 14 are held inside each other so as to be telescopically slidable. Radial positioning takes place in that the angle α14 between the components 141, 142 of the traverse 14 is changed or in that in the case of a telescopic traverse 14, which constitutes a chord in the track 11, the length is altered.

## Claims

### Claim 1

A device (1) for positioning the measuring element of measuring apparatus, comprising a traverse (14) on which the measuring element is arranged, and comprising an annular or arcuate track (11) as well as bearings (12, 13) that are movable on the track (11), on which bearings (12, 13) the traverse (14) is held, and the measuring element of the measuring apparatus can be positioned radially in relation to the track (11) and along the track (11), characterised in that the traverse (14) comprises multiple components, wherein the components (141, 142) of the traverse (14) are interconnected with one or several bearings (143), or the components (141, 142) of the traverse (14) are held inside each other so as to be telescopically slidable.

### Claim 2 (depends on 1)

The device according to claim 1, in which the components (141, 142) of the traverse (14) are connected to a pivot bearing (143) or bending bearing.

### Claim 3 (depends on 2)

The device according to claim 2, in which the pivot bearing (143) or bending bearing between the components (141, 142) of the traverse (14) permits angular positions in the region of acute and/or obtuse angles and/or angles of 180° and/or concave angles α14.

### Claim 4 (depends on 1)

The device according to claim 1, in which the bearings (12, 13) that are movable on the track (11) between the track (11) and the traverse (14) are pivoted bolsters which can be moved on the track (11) towards each other, away from each other as well as in unison with each other, at identical speed or at a different speed.

### Claim 5 (depends on 1)

The device according to claim 1, in which the traverse (14) in the region of its two ends with pivot bearings (124, 125) is connected to the bearings movable on the track (11) or is connected to the pivoted bolsters (12, 13).

### Claim 6 (depends on 1)

The device according to claim 1, comprising a traverse (14) with a sole pivot bearing (143) or bending bearing between the bearings or pivoted bolsters (12, 13) that are movable on the track (11), and comprising a servomotor and lever drive for setting the angle (α14) between the components (141, 142) of the traverse (14), which components are connected to the pivot bearing (143) or bending bearing.

### Claim 7 (depends on 1)

The device according to claim 1, in which at least one of the bearings that are movable on the track (11) or at least one of the pivoted bolsters (12, 13) comprises a drive motor, preferably an electric motor, in order to move both movable bearings or pivoted bolsters (12, 13) with the traverse (14) and with the measuring element along the track (11).

### Claim 8 (depends on 1)

The device according claim 1, comprising a carrier arm on which the measuring element of the measuring unit is arranged, wherein said carrier arm is installed on the traverse (14), and wherein said carrier arm with the measuring element arranged thereon can be slid or telescopically extended or retracted in a specifiable direction, preferably in radial direction in relation to the track (11).

### Claim 9 (depends on 1)

The device according to claim 1, comprising a measuring unit for measuring the thickness of plastic film, comprising a measuring element which operates capacitively, optically, thermally, acoustically or with the use of radioactive radiation, in particular β-radiation or γ-radiation.
