- the spring housing 20 has in Fig. 1 not to be recognized as a coupling portion formed first fastening means which can be positively connected to the connection of the spring housing 20 with the clamping unit 16 with the coupling portion 18 of the clamping unit 16.
- the spring housing 20 On the side facing away from the first fastening means, the spring housing 20 has second fastening means in the form of a toothed splined shaft 24 as a coupling portion.
- the spring housing 20 also has an annular groove 26 extending over its circumference, into which an actuating clamp 28 can be inserted. Via a screw 30, the actuating clamp 28 can be braced in the inserted state in the annular groove 26 and thus secured to the spring housing 20.
- At an operating portion of the actuating clamp 28 serving as a stop driver 32 is fixed, for example, releasably by a standard screw.
- the spring housing 20 on its side facing away from the clamping unit 16 inner side in the example shown has three arcuate slots 34.
- the profile roller cage 36 has an intermediate plate 38 and a front plate 40. Between the intermediate plate 38 and the front plate 40, three eccentric shafts 42 are arranged in the example shown, each of which rotatably support a profile roller, not shown.
- the front panel 40 and the intermediate plate 38 are held in the example shown three spacer bolts 44 at a distance.
- the spacer bolts 44 are each bolted by a screw 46 to the front panel. At their opposite end, the spacer bolts 44 each have an end portion 48 with external thread.

- the bearing unit 14 must be rotated from spring housing 20 together with closing clamp 28 and profile roller cage 36 in the opposite direction until the aforementioned dog clutch engages again. Since in the described opening movement, the bearing unit 14 has been axially removed from the clamping unit 16 with the shaft 10, a tensile force has been exerted on the coil spring 22. With the help of the pre-tension generated in this way, the jaw clutch is re-engaged. Thus, the profile rollers are back in their machining position, the thread rolling head is thus closed for a new machining operation.
- a second embodiment of a profile roller cage 36 ' is shown.
- the spacer bolts 44' are designed in such a way that the profiled roller cage 36 'is partially closed over its circumference. This is desirable in some applications. It is also possible, for example, instead of the profile roller cage 36 shown in Figures 2 and 3, to insert the profiled roller cage 36 "shown in Figures 6 and 7 into the thread rolling head of Figure 1.
- this profiled roller cage 36" substantially corresponds to the one shown in Figs 2 and 3
