Abstract

The invention relates to a mold to shape a substantially ring-shaped body, comprising a plurality of outer mold segments (14/28) which can be displaced radially and are held together by a ring (outer ring 16) having conical sliding surface (18) that faces said mold segments. Clasping elements (24), each of which is connected to a mold segment (14/28), engage in an undercut groove (20) on the conical sliding surface so that the mold segments can move radially when the ring (16) is axially displaced, wherein at least one support surface (26) comes to rest on a wall surface of a groove (22). In order to enable sequential opening of said mold, thereby reducing the forces exerted upon the tires or a different ring-shaped body during the shaping process, the invention provides that the cross section of certain clasping elements (24) are dimensioned in such a way that the support surface (26) comes to rest on the corresponding wall surface of the groove (22) much later as compared with the support surface of the other clasping elements when the outer ring is axially displaced.
