Abstract
Rolling mills commonly have rollers with shoulders abutting face plates on the frame of the mill. Dirt collects at the interface of the roller shoulders and face plates. There is no simple way to clean that interfacial area. Novel shields positioned against the roller shoulders and movable therefrom now permit facile cleaning of both the roller shoulders and shields. Frequent cleaning is critical in rolling mills of not only the food industry to prevent bacterial contamination of food products but also other industries where gritty material migrates into the interfacial area of roller shoulders and causes abrasion thereof. The shields can be as simple as stiff plastic sheets.
Claims14
In a rolling mill having at least one pair of compression rollers, each of said rollers having a shoulder and an axle at its opposite ends, the improvement of a movable shield abutted against the shoulders at each of the opposite ends of said rollers, each said shield having at least one pair of circular openings in which the axles of said rollers are fitted and being a flat stiff plate of which at least the face that abuts said shoulders of said rollers is a material offering low frictional resistance to the rotation of said rollers.
