ABSTRACT:
In the feeding of a strip of tire building material to a former, it is desirable to achieve a butt-joint between the ends of the strip when it has been wrapped fully around the circumference of the former (which may already have some material which has been wrapped around its surface in a previous operation). As the strip is fed to the former, its length is measured and the diameter of the former is adjusted if necessary to match the circumference of the former (and any existing material thereon) to the length of the strip.
