20170326825 · 2017-11-16 · ·

An apparatus for building a tyre for a vehicle wheel includes a building drum having at least one first outer circumferential surface, and at least one pair of auxiliary support members removably in engagement with the building drum, each in axial side by side relationship with a respective end of the building drum and having second outer circumferential surfaces extending in the continuation of the first outer circumferential surface so as to support at least one component of the tyre. Each of the second outer circumferential surfaces has at least one non-stick circumferential portion and at least one sticking circumferential portion.

Tyre layer application assembly and method

A tire layer application assembly and a method for applying a tire layer around a substantially circular circumferential surface of an object. The assembly is provided with a drive which, during application, is coupled to the object for driving the object in a driven rotation about a concentric axis of rotation with respect to the circumferential surface, wherein the assembly includes a tracking device which, during application, is arranged to be fixed to a part of the tire layer that is applied to the circumferential surface, wherein the tracking device is rotatable in a tracking rotation about the axis of rotation of the object, independent of the driven rotation of the object about the same axis of rotation.
