Abstract
A tire rubber extruder automatic loading and management system is provided for continuous and automatic control of a rubber extrusion line. Batches of rubber slab material, whether for sidewall or tread, are connected in an automated manner to provide a continuous material stream for feeding a tread extruder supply conveyor within a tire manufacturing system. Joiner between adjacent slabs are implemented utilizing a stitched joint of material. Stitch pins are driven through both rubber slab layers to a specific depth into a clearance hole to create an optimized rubber mechanical adhesion zone. The result is a funnel shaped adhesion channel penetrating entirely through the layers of material perpendicular to the direction slab movement and tension. The resulting “rivet” like button structures are extremely strong, have no Impurities that could otherwise be added via adhesives, and can be formed in an automated manner within the available process cycle times.
