METHOD FOR MANUFACTURING A SINGLE BELT/OVERLAY COMPONENT FOR A PNEUMATIC TIRE

A method in accordance with the present invention manufactures a tire with a biaxial monolayer belt component (MBC). The method comprises the steps of: winding a cord continuously about a first drum according to a pre-defined pattern to create a mesh of cords defining a single belt/overlay structure; adjusting the structure to a predetermined position on the first drum by laser lights; applying a tread component to the structure; transferring the structure and tread component to a second drum; applying the structure and tread component to a carcass component on the second drum; reducing pressure of the carcass component by a predetermined amount; and stitching the structure and tread component to the carcass component.

20170050468 · 2017-02-23 ·

A flat or planar reinforcer shaped as a multicomposite strip (R1), which is defined by three main perpendicular directions: an axial direction (X), a transverse direction (Y), and a radial direction (Z), has a width L.sub.R in the Y direction of between 2 and 100 mm, and has a thickness E.sub.R in the Z direction of between 0.1 and 5 mm. A ratio L.sub.R/E.sub.R is greater than 3. The multicomposite strip includes a plurality of monofilaments made of a composite material. The monofilaments are oriented along the X direction and include filaments of a mineral material embedded in a thermoset resin having a glass transition temperature Tg.sub.1 that is greater than 70 C. The monofilaments are coated in a layer of thermoplastic material. The reinforcer may be used to reinforce a tire and a multilayer laminate, which may be used to reinforce a tire.
