Beschreibung
Zusammenfassung:	The object of the invention is a spragging mechanism for application in a tube. It is provided with a band and clamping means. The clamping means are arranged within the tube, outside of which the band is provided. The object of the invention is also a system for guiding bore head, provided with an spragging mechanism, head, means transferring the pressing force to the bore head, and also a curled tube fed from the drum into the wellbore. The curled tube (1) constitutes means transferring the pressing force, exerted by the pressing mechanism (2) via a mechanism releasably connected to the curled tube (1). The object of the invention is also a method of drilling a wellbore, wherein a bore head with an drill bit is lowered down the wellbore and pressed against its bottom, simultaneously inserting a tube into to wellbore. For pressing the head (9) with the drill bit (8) a tube (1) curled of strip (T1) drawn from a drum is used, wherein the pressing force is applied to the tube via a mechanism (11, 13, 2) releasably connected thereto.
