Problems solved by technology

During such a process, the rolls may pick up material from the web and thus contaminate the surface of the roll.
Such contamination can lead to reduction in the quality of the process and may result in unsatisfactory material being produced.
On some occasions steel customers have returned rolled steel coils because of rust on the coils as delivered.

Abstract

A roll cleaning apparatus having a cleaning member mounted to a support member that extends lengthwise relative to a first roller of the machine. The cleaning member has a brush having a substantial area to place against the surface of the roll. The cleaning member may be movable between an engaged position against the roll during operation, and a disengaged position spaced away from the roll in a non-operating condition, such as when replacement of the cleaning member is desired. The roll cleaning apparatus may include a drive connected to cause linear reciprocation of the cleaning member. The roll cleaning apparatus may have a drive or actuator mounted to move the cleaning member between the engaged and disengaged positions, and may be operable to bias the cleaning member against the roll in use. The roll cleaning member may have a contact head that includes an array of abrasive bristles.

Description

FIELD OF THE INVENTION[0001]The present invention relates to methods and apparatus for cleaning rolls.BACKGROUND OF THE INVENTION[0002]Many industrial processes use rolls to either treat or form a web of material. Typical of such applications are papermaking and metal rolling mills, in which, at various stages of the process a generally planar or web-like workpiece is passed between rollers. During such a process, the rolls may pick up material from the web and thus contaminate the surface of the roll. Such contamination can lead to reduction in the quality of the process and may result in unsatisfactory material being produced.[0003]It has previously been suggested to remove material from the roll by using a doctor blade. In papermaking, for example, it may be that rolls in a calendar stack are heated. Heating may be used when papers of particular chemical compositions, e.g., relatively high clay or starch content and gloss finish are produced. The warmth may increase the tendency ...
