Abstract
This invention relates to a bead lock arrangement for use in tire building equipment, and to tire building equipment utilizing such a bead lock arrangement. A bead lock assembly is disclosed comprising first and second parallel, coaxial, axially spaced bead lock arrangements (), each bead lock arrangement including an annular, extensible, bead seating ring () encircling the radially movable segments () of the bead lock arrangement and having, at its radially outermost face, a circumferentially extending bead seating surface (), and an annular sealing ring () positioned coaxial with the respective bead seating ring () and disposed adjacent a side face of the respective bead seating ring () presented generally towards the bead seating ring () of the opposing bead lock arrangement. The use of a bead seating ring () and a separately formed sealing ring () has considerable advantages over the use of a conventional bead seating ring. The use of a separate, extensible bead seating ring () and a non-expanding sealing ring () allows the production of less complex items having extended service life.
