The invention relates to a thread rolling tool for rolling and/or repairing a thread, comprising a clamping device to be fastened to a pipe end, and at least one profiled roll for rolling a thread into the pipe end or repairing a thread at the pipe end. According to the invention, the at least one profiled roll tapers in a direction in which the profiled roll advances such that a tapered, in particular a conical, thread can be rolled into the pipe end. 1. Thread-rolling tool for rolling and/or repairing a thread , with{'b': 12', '18, 'a) a clamping jig () for fastening to a pipe end () and'}{'b': 14', '1', '18', '18, 'b) at least one profile roll (.) for rolling a thread into the pipe end () or for repairing a thread at the pipe end (),'}wherein{'b': 14', '1', '14', '18, 'c) the at least one profile roll (.) tapers in a feed direction of the profile roll (), so that a tapering, especially a conical thread can be rolled into the pipe end ().'}214. Thread-rolling tool according to claim 1 , wherein the profile roll () is pitchless.3. Thread-rolling tool according to claim 1 , comprising{'b': '16', 'claim-text': [{'b': 14', '1, 'on which the at least one profile roll (.) is fastened and'}, {'b': 14', '1', '18', '14', '1', '18, 'by means of which the at least one profile roll (.) can be so guided helically around the pipe end () that the at least one profile roll (.) rolls a thread into the pipe end ().'}], 'a roll holder (),'}4. Thread-rolling tool according to claim 1 , wherein{'b': 16', '26', '12', '16', '18', '16, 'the roll holder () is coupled by means of a thread () with the clamping jig (), so that a rotation of the roll holder () around a pipe longitudinal axis (L) of the pipe end () leads to an axial movement of the roll holder () along the pipe longitudinal axis (L).'}514216. Thread-rolling tool according to claim 1 , comprising at least one second profile roll (.) claim 1 , which is so fastened to the roll holder () that{'b': 14', '2', '16', '14', '1, 'the ...
