Beschreibung
Zusammenfassung:	A method of producing tubes from sheet metal blanks on a mill comprising the steps of: feeding said blanks in a sequence; measuring the length of each sheet metal blank; leaving the pairs composed of the blanks approximate in length in the sequence by removing from the sequence the unpaired blanks, ensuring pairing of the blanks removed from the sequence but meeting the pre-set limits as to their difference in length. Following that the known treatment of the edges being welded is performed, alternate forming of each sheet metal blank assembly in pairs and welding of said blanks into tubes with subsequent trimming of the tube ends.
