Abstract
Abstract The invention relates to a process of building a tire with reinforcing elements which lie in planes which are substantially radial with respect to the tire axis. The tire is built on adjacent drum parts whose outside diameter is the diameter of the tire, and these are movable axially from the sides of an inflated bladder of the same diameter. Plies with parallel reinforcing elements are placed on the drum surface, with the reinforcing elements extending substantially perpendicularly to the center plane of the bladder. The drum parts are then moved away from the tire and the plies are brought down around the bladder, and beads are turned up in their edges.
