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.

Abstract: A machine for cutting a profile into the respective ends of a flat rectangular piece of rubberized material having a clamping table with an overhead reciprocating carriage that has a rotating profile cutter that cuts an interlocking profile at a single pass into such material.

Abstract: A cylindrical expandable sleeve for use in a curing process wherein a pair of annular end portions and a cylindrical expandable body have a longitudinally extending splice with interlocking ribs and surfaces to firmly interconnect such body into a unitary whole for use in successive expansions and contractions.

Abstract: An apparatus for brushing hose, having a cleaning head with a plurality of circumferentially spaced brushes adjustable about the pass line of a hose that is guided through the cleaning head. The brushes are rotated while the hose is moved linearly through the cleaning head. Adjusting means are provided to position the brushes radially relative to the pass line.
