Abstract:
A coated metal reinforcement element for polymeric or elastomeric materials comprises a coating of: a polymer or prepolymer compatible with and co-polymerizable, co-vulcanizable or cross-linkable with said polymeric or elastomeric material to be reinforced, and bearing functional groups; either covalently bonding to the metal surface of said reinforcement element; or forming covalent bonds with the outward directed first functional groups of a mono- or multimolecular layer of a bifunctional adhesion promotor intercalated between said metal and said coating and bound to said metal by its second functional groups. A method for the coating includes a one step and a two step procedure.
Abstract:
A pneumatic tyre comprises a belt (7) disposed radially outside a carcass (6) in a tread portion (2), the belt (7) comprising two crossed plies (7A,7B) of monofilament metallic cords (10A,10B,10C) laid at angles of from 15 to 30 degrees with respect to the circumferential direction of the tyre, each monofilament cord being composed of a waved single filament, the filament having a circular sectional shape having a diameter in a range of from 0.40 to 0.50 mm, or alternatively a non-circular sectional shape having an aspect ratio in a range of from 0.65 to 0.95 and a cross-sectional area in a range of 0.09 to 0.20 sq.mm.
Abstract:
Reinforcement cord for elastomeric products, in particular reinforcement cords, for use in vehicle tyres comprising inner filaments (1) and at least one outer filament (2) wound helically around the inner filament (1), characterised in that at least the outer filament (2) has a flattened cross-section and is so dimensioned and positioned that it substantially co-determines the mechanical characteristics of the reinforcement cord via line-like and/or area contact locations with the inner filaments (1).
Abstract:
A composite rope obtained by process comprising, impregnating a multifilament (2) with epoxy resin and half-setting the resin to form a prepreg (5), twisting the plural prepregs (5) together to form a primarily-twisted product (15), and wrapping the primarily-twisted product (15) with a yarn (22) or a porous tape (42). When it is wound round the primarily-twisted product (15), the yarn (22) is closely wound at an angle substantially perpendicular to an axis of the primarily-twisted product (15). The method further comprises twisting the plural primarily-twisted products (15) thus wrapped to form a secondarily-twisted product (25, 45) and then heating the secondarily-twisted product (25, 45) to completely set the resin impregnated.
Abstract:
A rope (1) for traction having a double structure of a core member (2) coated with a sheath member (3), wherein said core member (2) comprises a molecularly oriented shaped article of an ultrahigh molecular weight polyolefin, and said sheath member (3) comprises a braid.
Abstract:
A steel element for reinforcing a rubber article comprises a brass layer and at least one additional outer film of metal or metal alloy selected from the group containing Fe, Ni, Mn, Cr, Mb, Va, Ti, Zi, Nb, Ta, Hf and W.
Abstract:
