Abstract
A rigid fixed diameter cylindrical drum for building a tire band, i.e., a straight cylindrical ply assembly without bead rings or other circumferentially inextensible elements subsequently to be a part of a complete tire, is enabled to release the band built thereon for coaxial movement of the cylindrical band off the drum. The cylindrical surface of the drum is knurled in a coarse diamond-toothed pattern. Perforations or orifices for air pressure and flow are also provided. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
