Abstract

The crimp is fed under an endless belt and then contacted with a revolving drum, the lower portion of which dips into a trough containing of solution of the reinforcer. As the folds of the crimp touch this, a layer is picked up and when the dolvent dries off, each of the folds has been given a layer of reinforcement. These then form then outer surface of the filter cartridge.
