Apparatus for manufacturing a tire by the laying of rubber products onto a rotating core
First Claim
1. An apparatus for manufacturing a tire comprising a rigid core rotatable about an axis and having an outer surface defining the interior shape of a tier to be manufactured, a gantry surrounding the rigid core, a plurality of volumetric extruders supported on the gantry, each having a discharge adjacent the outer surface of the rotatable core for extruding strips of rubber to build up a tire blank on the core in a plurality of revolutions of the core and means for imparting meridian relative movements to the extruders relative to the surface on which rubber is to be applied during the rotation of the surface.

Abstract
The rubber products forming a part of the structure of a tire are laid onto a rigid core by means of a volumetric extruder having an outlet orifice of small size positioned close to the surface on which the rubber is to be applied. The rubber products are built up by a meridian displacement of the orifice relative to the receiving surface with the extrusion of a controlled volume of rubber.
