ABSTRACT:
The invention relates to the production of a metal strip having formed-in thinner areas. To this end the strip B is drawn through a drawing nip 1, 2 formed by the end face of a working roll 3 adjusted at an angle and a support roll 4, which can take the form of a working roll. When drawing takes place through the working nip 1, 2, a rolling force and simultaneously a tensile force transversely of the pulling direction are so exerted on the strip B by the two rolls 3, 4 that the displaced material flows practically exclusively transversely of the pulling direction in the areas to be thinned down.
