Abstract
Abstract An improved bearing and seal is used in a clothes dryer having an endless belt for a tumbler with the belt being driven in matching channels formed in a pair of opposed upright panels. Carriers secured to the belt extend all around each edge of the belt and have a metallic element extending over the edge of the belt and disposed in the channel. Each of the carriers has a continuous pile strip disposed along the inside of the belt to engage inner edges of the channels to form a sealing barrier keeping lint and air from entering the channels, and each of the carriers has wear-resistant, low-friction material engaging the sides and bottoms of the channels to provide a running fit for the belt in the channels.
