Abstract

A method for controlling the positions of displaceable pressure rollers during the start-up of coiling strips in reeling installations. The method includes raising pressure rollers from a mandrel of the reeling installation before the strip beginning enters and before the next winding is placed. After the strip beginning has passed each pressure roller, the mandrel is moved into a position of operation. The gap between the pressure rollers in operating position and the mandrel is adjusted to at least n times the strip thickness, wherein n is the number of windings of the strip at each pressure roller. A slip-free contact of the strip on the mandrel is effected by spreading segments of the mandrel. Thus, the pressure rollers are moved as closely as possible to the mandrel while not exerting any pressure forces on the mandrel or only the last pressure roller in strip travel direction presses the strip against the mandrel and the remaining pressure rollers place the strip as closely as possible to the mandrel without exerting any pressure forces on the strip and the mandrel.
