Abstract

A one-piece polyethylene apron-gutter has been developed and marketed to complement the plastic cup. The plastic system eliminates contamination from iron cups and gutters which have reduced gum grades for 70 years. Sulfuric acid will not attack the plastic apron-gutters. and the new system should prove durable for at least 4 years of continuous use.

Keywords
