Abstract
In a method of an apparatus for the manufacture of a flexible reinforced polymeric article, such as a breaker fabric for a pneumatic tire, a layer of polymeric material is fed from feed means to a conveyor and a pair of laying head carriages are arranged to lay to and fro over said polymeric layer two reinforcing cords in an arrangement in which two successive transverse portions of one cord lie interdigitated between two successive transverse portions of the other cord in a manner whereby the two cords are free from overlapping cross-over regions. Means may be provided for applying a second layer of polymeric material whereby the cords are embedded between and consolidated in said polymeric layers.
