Abstract
A process for applying a defined surface roughness to a metal strip, especially steel strip, for preventing the sticking of strip during subsequent annealing in a bell-type annealing installation includes cold rolling the metal strip in at least one reversing roll stand. The cold rolled metal strip is then guided to a temper rolling stand for wet rolling the cold rolled metal strip through at least one pass for applying the defined surface roughness to the metal strip. For this purpose, the flattening rolls of the temper rolling stand are replaced with rough rolls.
