ABSTRACT:
A radially expandable and contractable tire building drum has a drawbar positioned along the centerline of the drum, a slidable cone fixed to the drawbar, and a plurality of slides connected to the cone and extending in a radial array therefrom. The slides are guided for motion only radially toward and away from the centerline. Each slide carries a corresponding drum segment having an arcuate outer surface, and the surfaces of the segment cooperate to form a cylindrical building surface on the drum exterior. Motion of the drawbar along the centerline cause the conical adjusting member to move the slides concurrently in a radial direction, expanding or contracting the building surface. Edges of the drum segments arcuate surfaces include scallops, as in the form of tongues and corresponding cavities, which cooperate as the drum segments move outward to maintain some surface continuity lengthwise of the drum building surface.
