ABSTRACT:
A rolling mill system has oppositely driven, temperature-controlled first and second rolls, each having a first roll half with a first end face, a second roll half with a second end face, and a roll center. The first roll has a peripheral surface with open grooves arranged on the first and second roll halves and with ribs between the grooves. The grooves of the roll halves are arranged opposed to one another at an obtuse angle and symmetrically to the roll center. The width of the ribs is smaller than the width of the grooves. The grooves extend continuously between the end faces. The second roll has a smooth peripheral surface. First and second cutting devices are arranged at the first and second end faces of the first roll, respectively. The cutting devices are arranged near open ends of the grooves.
