Patent number: 8459074Abstract: A strip has a strip head and a strip leg. It is rolled, beginning at the strip head, in a roll stand of a rolling device between an upper and a lower roller arrangement of the roll stand. It is monitored whether the strip foot reaches a switching point located, viewed in the rolling direction, in front of the roll stand. From the time the strip leg reaches the switching point, the roller arrangements are subjected to a bending force expanding the roller arrangements by means of an adjusting device, the force being at least as high as a minimal force. The minimal force is at least as high as a balancing force of the upper roller arrangement. The minimal force is determined as a function of the parameters of the strip and/or the operating parameters of the rolling device.Type: GrantFiled: October 19, 2007Date of Patent: June 11, 2013Assignee: Siemens AktiengesellschaftInventors: Wolfgang Hofer, Markus Martini
