The disclosure provides a process for manufacturing a tread molding element configured to mold at least a portion of a tire tread, the process comprising the steps of modeling a three-dimensional shape of a tread molding element through a modeling program that can be recognized by a 3D printer; providing one or more plastic compositions comprising one or more thermoplastic polymers having a melting point of at least 180° C.; forming a tread molding element by 3D printing from the one or more plastic compositions; and optionally annealing the tread molding element.

A shear band for a tire includes a first belt layer extending circumferentially around the tire, a second belt layer extending circumferentially around the tire, and a shear band radially interposed between the first belt layer and the second belt layer. The shear band includes a first reinforcing ply radially adjacent the first belt layer, a third reinforcing ply radially adjacent the second belt layer, and a second reinforcing ply radially interposed between the first reinforcing ply and the second reinforcing ply. The first reinforcing ply includes a first flattened, braided tube layer enclosed by a first rubber layer. The second reinforcing ply includes a second flattened, braided tube layer enclosed by a second rubber layer. The third reinforcing ply includes a third flattened, braided tube layer enclosed by a third rubber layer.

An apparatus for welding monofilaments at a loom makes possible a method for a continuous process for weaving monofilaments into fabric. The apparatus comprises a stand ( ) on which is mounted welding apparatus ( ) and a filament alignment block ( ). In the method, a monofilament ( ) in the loom is welded to the leading end of a monofilament ( ) on a new spool of monofilament. By welding new monofilament to monofilament in the loom, restringing of the loom is avoided.

Method and apparatus for connecting cords/filaments

This invention is directed to treating the surfaces of rubber-reinforcing materials with a gas plasma of O.sub.2 and CF.sub.4 to activate the surfaces to make them more receptive to adhesives. Optionally the surfaces of the reinforcing materials may be exposed to a polymerizing gas plasma such as a thio-carbon to coat the surfaces of the reinforcing material with substances that promote adhesion to rubber. The treated surfaces have been shown to adhere directly to rubber when vulcanized in the normal fashion.

Reinforcing elements comprise a plurality of elongated metallic members, with substantially rectangular cross sections, having parallel longitudinal axes and at least one of the wide sides of each being contiguous with a wide side of another of said elongated metallic members. A single wrap member is helically disposed around the elongated metallic members such that each turn of the wrap filament member is spaced apart from the next adjacent turns of the wrap member. Elastomeric articles reinforced with these reinforcing elements are also disclosed.
