ABSTRACT:
A method and an arrangement for the treatment of metal strip, particularly for the treatment of hot-rolled metal strip in an entry portion of a pickling line through which the metal strip travels continuously. The method includes straightening the metal strip which is being uncoiled from an uncoiling reel under a predetermined strip tension, then severing the unstraightened ends of the strip for producing straightened ends of the strips, and subsequently connecting the strip end of an advancing metal strip to a strip end of a subsequent metal strip. Immediately after being uncoiled, the metal strip is straightened by stretch-bending and a strip tension is produced which is sufficiently high for straightening by stretch-bending without increasing the uncoiling tension.
