Abstract

Die Erfindung betrifft ein Walzgerüst mit zwei Arbeits­ walzen (2, 3), deren Walzballen deckungsgleiche über ihre Länge konvex gekrümmte Konturen aufweisen und die ggf. an Stützwalzen (6, 7) anliegen. Zur Erzeugung planer Bän­ der war es bekannt, die Arbeitswalzen (2, 3) so zu bombie­ ren, daß nach der Biegung der Walzen unter Walzkraft die Biegung durch die Bombierung kompensiert war und somit ein planes Band entstand. Als nachteilig wurde erkannt, daß die gewählte Bombierung in der Praxis nur für eine be­ stimmte Walzkraft und eine bestimmte Bandbreite richtig war. Aufgabe der Erfindung ist es deshalb, eine Walzen­ bombierung zu schaffen, mit der unterschiedliche Bänder unterschiedlicher Breite herstellbar sind. Zur Lösung der Aufgabe wird vorgeschlagen, die Walzen (2, 3) über ihre Ballenbreite unterschiedlich, jedoch stets konvex zu bom­ bieren, so daß sich eine Zigarrenform der Walzen (2, 3) ergibt wobei der größte Durchmesser (D) außerhalb der Mitte dieser Walzen, jedoch - bezogen auf die jeweils ge­ genüberliegende Arbeitswalze (2 oder 3) - auf der anderen Seite der Walzmitte (8) liegt. Die Walzen (2, 3) sind in Achs­ richtung verstellbar. The invention relates to a roll stand with two working rolls (2, 3), whose rolled bales congruent over their Length have convexly curved contours and the rest on support rollers (6, 7). For the production of flat banks he was known to bombie the work rolls (2, 3) like this ren that after the bending of the rollers under rolling force Bending was compensated by the crowning and thus a flat band was created. It was recognized as a disadvantage that the selected crowning in practice only for one be corrected rolling force and a certain range correctly was. The object of the invention is therefore a roller to create bombing with the different tapes different widths can be produced. To solve the It is proposed to roll the rollers (2, 3) over their Bale width different, but always convex to bom beers, so that a cigar shape of the rollers (2, 3) results in the largest diameter (D) outside the Middle of these rollers, however - based on the ge opposite work roll (2 or 3) - on the other Side of the center of the roll (8). The rollers (2, 3) are in axis adjustable direction.
