  • Device for producing a two-part tire layer
    Patent number: 6866494
    Abstract: In a road vehicle tire, a two-part layer (2) of elastomeric material is preassembled by co-extruding a first and a second strip (19, 16) through a preforming plate die (26), through which extends at least one pair (27) of tapered flow channels (25a, 25b) having offset, side by side inlets (28, 29) with respective superimposed adjacent lateral portions (30, 32), and substantially coplanar outlets (33, 34) with respective adjacent lateral portions (35, 38) interconnected to define, between the two strips (19, 16), an L-shaped joint (20) wherein a lateral portion (21) of the second strip (16) has an edge (17) substantially contacting a lateral shoulder (22) of the first strip (19), and is superimposed on a thin annular appendix (23) projecting from the shoulder (22) of the first strip (19).
