Abstract From the Canadian patent

Abstract of the Disclosure A tire bead assembly of a bead core, apex and gum tie strip is made by laying the gum tie strip about a non-inflatable annular member of triangular cross-section and across the slant surface of the member. The apex is wrapped then about the tie strip and about the slant surface of an annular inflatable bag. After the core is pressed coaxially on the tie strip so as to indent the member and thus preform the tie strip, the bag is inflated to turn the apex and underlying the strip about the core and against an annular forming member to shape the assembly suitably for the tire carcass in which it is to be inserted.
