SCRAPER BARS FOR USE WITH CONVEYOR BELTING AND THE LIKE

摘要

A scraper bar for use with conveyor belting and the like to clean such belting of material adhering to its surface. The scraper bar consists of a layer of hard abrasion-resistant pellets embedded in an elastomer to form an elastomer/pellet matrix. An additional layer of elastomer is cast to the matrixed layer to provide a surface for attaching the scraper to its support when in service. Embedded in the layer of unmatrixed elastomer is an insert of particle board, chipboard, plywood or fiberglass reinforced plastic sheeting. The insert prevents bending of the scraper bar due to differential shrinkage between the layer of matrixed elastomer and pellets and the supporting layer of elastomer.
