Tyre layer application assembly and method

Tyre layer application assembly for applying a tyre layer around a substantially circular circumferential surface of an object, wherein 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 said circumferential surface, wherein the assembly comprises a tracking device which, during application, is arranged to be fixed to a part of the tyre 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.

Method for applying a tyre layer around a substantially circular circumferential surface of an object, wherein the method comprises the steps of driving the object in driven rotation about an axis of rotation, applying a part of the tyre layer to the circumferential surface of the object, fixing a tracking device to the part of the tyre layer that is applied to the object, rotating the tracking device with the part of the tyre layer to which it is fixed 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.
