Abstract

Die Erfindung bezieht sich auf das Herstellen eines Metallbandes mit eingeformten dünneren Streifen. Dazu wird das Band B durch einen Ziehspalt 1,2 gezogen, der von der Stirnseite einer geneigt angestellten Arbeitsrolle 3 und einer Stützrolle 4 gebildet wird, die als Arbeitswalze ausgebildet sein kann. Beim Ziehen durch diesen Arbeitsspalt 1,2 wird von den beiden Rollen 3,4 auf das Band B eine Walzkraft und gleichzeitig eine Zugkraft quer zur Zugrichtung ausgeübt derart, daß das verdrängte Material in den auszudünnenden Bereichen praktisch ausschließlich quer zur Zugrichtung fließt.

Figure 00000001
The invention relates to the production of a metal strip with molded thinner strips. For this purpose, the band B is drawn through a drawing gap 1, 2, which is formed by the end face of an inclined working roll 3 and a support roll 4, which can be designed as a working roll. When pulling through this working gap 1, 2, a rolling force and at the same time a tensile force is exerted on the belt B transversely to the tensile direction in such a way that the displaced material flows practically exclusively in the areas to be thinned transversely to the tensile direction.
