REINFORCED CLEANING BLADE AND METHOD OF MANUFACTURING THEREOF

摘要

A reinforced conveyor belt cleaning blade is provided. In one form, the reinforced cleaning blade includes a blade body and a metal insert that is of a substantially constant cross-sectional configuration extending between the ends thereof. The ends are surrounded by molded material of the blade body so that the blade body and insert have a secure connection therebetween. The preferred insert is a formed sheet metal member that has smooth surfaces extending along its length without projections or sharp corners. In another aspect, a method of manufacturing a conveyor belt cleaning blade is provided including placing a metallic insert for the cleaning blade in a mold and molding the body of the cleaning blade with polymeric material extending completely around ends of the insert. Preferably, the insert is magnetically held in position in the mold such as on a rail on which magnets are mounted.
