<p>The tool has two thread rollers (5.1) drivingly coupled with each other via a non-driven gear and a synchronous belt and interchangeably mounted on a roller pin (6.1) within free ends of a roller head arm (2.1). An axial backlash of the thread rollers is adjustable by rotatable adjustable sleeves (40) towards lateral surfaces. The adjustable sleeves include individual-axially arranged helical surface portions, which are supported against same number of fixed points in the roller head arm. Fixed points of cylindrical pins are fixedly connected with the roller head arm.</p> |
