Abstract
A mechanism for producing the bead on a rubber article made by a dipping process first loosens the rubber film on the form using a pair of looseners in the form of roller brushes which contact the lower portion of each form as the forms are moving along on the form carriage. As the forms move along on the form carriage, the looseners move in the same direction as the form carriage but at a different speed, so that the roller brushes roll around the entire circumference of the lower portion of each form to thoroughly loosen the edge of the rubber film from the form. Following the loosening operation, the beads are formed by a separate bead roller mechanism which provides a bead of predetermined dimensions by rolling up the edge of the film a predetermined amount. The bead rolling operation is accomplished by a pair of roller brushes which are mounted diagonally with respect to the direction of travel of the form carriage.
