METHOD AND DEVICE FOR WINDING A METAL STRIP

摘要

The invention relates to a method for winding a metal strip (I) into a reel with a winding mandrel (2), to which the metal strip (1) is routed through a pair consisting of a first and a second driver roller (5, 6), at least one of which is driven, The method is characterized in that a difference between the strip speed (VB) of the metal strip (1) and the speed) (v5, v6) of the driver rollers is adjusted on the basis of measuring, from measurable process variables, the strip speed and the speed (v5, v6) of at least one of the driver rollers (5, 6).

1. A method of winding metal strip (2) on a reel having a mandrel to which the metal strip (2) is routed by a pair of first and second driver rollers (3, 4) of which at least one is driven, wherein
a difference between a strip speed (VB) of the metal strip (2) and a speed of the driver rollers is adjusted based on measurement of the strip speed and the speed (Vu, Vo) of at least one of the driver rollers (3, 4) from measurable process variables, characterized in that a controller (16) so controls the difference between the strip speed (VB) of the metal strip (2) and the speed of at least one of the driver rollers (3, 4) that the difference between the strip speed (VB) and a surface or circumferential speed (Vu, Vo) of the driver rollers (3, 4) does not exceed an adjustable threshold.
