A simple compact apparatus for applying sheet material, e.g., gum liner or radial ply stock, to a tire building drum has a plurality of rings carried on flanged rolls on three shafts. The rings form a hollow cylinder in which a cylinder actuates shoes disposed respectively between adjacent rings to lift the sheet cut off by a pair of piercing blades (for ply stock) traversed oppositely each way from center or by a single blade (for gum liner stock). One flanged roll with the rings between respective pairs of flanges forms a continuous line nip with a tire building drum for transferring the sheet from the apparatus to the building drum. 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.
