Abstract: The invention relates to a tangential thread rolling head including two rolling head arms having a thread roll rotatably mounted on an axle. The thread rolls are configured to engage with a gear and be pushed laterally into an assembled position into the rolling head arms before the installation of the axles and the axles can be pushed into a bearing bore hole of the thread rolls. The two thread rolls have identical thread profiles that are offset with respect to each other when the thread rolls are in the assembled position.

Abstract: The invention relates to a tangential thread rolling head comprising two fork-like rolling head arms each rotatably coupled with a thread roll by an axle. The thread rolls respectively engage with a pinion and can be pushed laterally into an assembled position into the rolling head arms before installation of axles, in which one of the axles can be pushed into a bearing bore hole of the thread rolls. The thread rolls and the pinions have interacting catches that are configured such that each of the thread rolls can only be pushed laterally into the assembled position in a single defined rotary position.

Abstract: A thread rolling head comprises a bearing unit, in which at least two profile rollers, preferably at least three profile rollers, are rotatably mounted, and a shank section coupled to the bearing unit. Adjacent profile rollers delimit an insertion section into which a workpiece to be machined can be inserted. The bearing unit is built from at least two modules each forming a functional unit, wherein the modules each have a fastener through which modules can be connected together and can be exchanged for other modules also each forming a functional unit. One of the modules has fasteners for connecting to corresponding fasteners of the shank section.
