Abstract
Apparatus to control and adjust the drawing action in a rolling mill provided with rolling stands through which a product passes. A video monitoring system acquires frames of the product; a processing system that processes the frames and defines a normal rolling range within which the product being rolled must be positioned; identifies the position of the product and its geometric characteristics; and identifies a possible variation of the position of the product being rolled over time based on the analysis of the sequence of frames acquired. An automation system is associated with the rolling mill, configured to receive data relating to the position of the product to determine the continuation of the rolling if the product is correctly positioned in the range, or a variation of the rolling parameters if the position of the product being rolled is able to generate a cobble which is outside of the range.
