ABSTRACT:
A feeder device is described that causes two or more strips of unvulcanized rubber composition to be fed simultaneously at substantially the same linear rate. The feeder device includes a pair of opposed feed rolls between which the rubber strips are drawn mounted to rotate freely about their respective axis. During operation of the feeder device the feed rolls are urged toward one another but not with sufficient force to cause cutting through of the rubber strips. The rate at which the strips simultaneously advance through the feeder device is determined by the speed at which feed rolls rotate which, in turn, is dependent upon the rate at which at least one of the rubber strips is being advanced.
