A roller head for a planetary rolling arrangement, said roller head comprising a housing, inside which housing there is rotatably arranged a hollow outer axis and means for rotating said outer axis, as well as inside said outer axis, in a manner that transmits the rotary motion thereof, a center axis which is movable in the axial direction and can be locked in the axial direction, said center axis being provided with a roller. The roller head is characterized by an adjusting axis which is rotatably arranged at the end of the outer axis that is located on the opposite side with respect to the roller and is essentially locked in the axial direction said adjusting axis comprising a counterpart for the threaded section provided in the center axis, and said adjusting axis also including a locking member, which in the locking position forms a friction coupling at least between the adjusting axis and the outer axis.

1. A roller head for a planetary rolling arrangement, comprising: a housing, a hollow outer shaft inside the housing, a drive means for rotating the outer shaft relative to the housing, an inner shaft inside the outer shaft, the inner shaft having a first end for attachment of a roller and also having a second end, the inner shaft having a threaded portion at its second end, a coupling means that couples the outer shaft to the inner shaft in a manner for transmitting rotational movement of the outer shaft to the inner shaft while permitting axial movement of the inner shaft relative to the outer shaft, an adjusting shaft extending partially within the outer shaft and having a threaded portion in threaded engagement with the threaded portion of the inner shaft, a means for limiting axial movement of the adjusting shaft relative to the outer shaft while permitting rotational movement of the adjusting shaft relative to the outer shaft, and a locking means for releasably locking the adjusting shaft against rotational movement relative to the outer shaft by frictional engagement with the outer shaft. 2. A roller head according to claim 1, wherein the locking member is an expansible, pressure-operated member. 3. A roller head according to claim 1, wherein the locking means comprises a hydraulically operated sleeve member. 4. A roller head according to claim 1, wherein the locking means is integral with the adjusting shaft. 5. A roller head according to claim 1, wherein the locking means is a separate sleeve member between the outer shaft and the adjusting shaft. 6. A roller head according to claim 1, wherein the threaded portion of the inner shaft is a portion that defines an internally threaded axial bore at the second end of the inner shaft and the threaded portion of the adjusting shaft is a length segment of the adjusting shaft that is externally threaded and is in threaded engagement with the internally threaded axial bore. 7. A roller head according to claim 1, comprising an installation device for engaging the adjusting shaft and turning the adjusting shaft relative to the inner and outer shafts, in order to effect axial movement of the inner shaft relative to the outer shaft. 8. A roller head according to claim 7, herein the installation device comprises a measuring device for measuring rotational movement of the adjusting shaft. 9. A roller head according to claim 1, wherein the outer shaft is supported in the housing by first and second radial-thrust bearing means and by an axial bearing between the first and second radial-thrust bearings. 10. A roller head according to claim 1, wherein the outer shaft has an end portion defining a passage through which the adjusting shaft extends, the passage being bounded by an inner wall of the outer shaft, and the locking means comprises a means defining a cavity in the adjusting shaft, the cavity having a deflectable outer wall, and a means for pressurizing the cavity, whereby the deflectable wall is forced into contact with the inner wall of the outer shaft. 11. A roller head according to claim 1, wherein the outer shaft has an end portion defining a passage through which the adjusting shaft extends, the passage having a first segment containing the threaded portion of the inner shaft and a second segment of smaller cross-sectional area than the first segment and farther from the first end of the inner shaft than from the second end of the inner shaft, the outer shaft includes an abutment portion between the first and second passages, and the means for limiting axial movement of the adjusting shaft includes a shoulder portion of the adjusting shaft disposed within the first passage of the outer shaft.
