Abstract
The invention relates to a method and device for measuring and influencing the strip flatness in the coiler shaft of a hot-strip mill, whereby the coiler shaft has, between a driver and a coiler, moving and stationary strip guides as well as a flatness measuring roll (). The hot strip () is supplied via the coiler shaft to a coiler, which is provided with a coiler mandrel (), pressure rolls () and with deflecting shells (), over a roller table () and the driving rolls () of the driver. The flatness measuring roll () is displaced out of a working position, in which the hot strip is guided around the flatness measuring roll () while maintaining an approximately constant contact angle α, and into a lowered position. In addition, a strip guide (), which can swivel inward and protects the flatness measuring roll (), is placed inside the coiler shaft.
