Abstract
A thread rolling head includes a bearing housing, in which at least two profile rollers, preferably at least three, are each rotatably mounted on an eccentric shaft. A shank is coupled to the housing, and adjacent profile rollers delimit an insertion section into which a workpiece can be longitudinally inserted. The bearing housing includes two housing parts rotatable relative to each other to change the spacing between the profile rollers. An adjustment element interacts with one of the two housing parts and can rotate about the longitudinal axis thereof. Rotation of the adjustment element in a first direction causes rotation of the two housing parts in a third rotational direction, while its rotation in the second direction causes rotation of the housing parts in a fourth rotational direction counter to the third rotational direction. A display apparatus displays a change of the spacing between the profile rollers.
