The matrix is filled with a polymer epoxy resin (). A top layer of fabric tape () soaked in resin () has been used to embed the finish end () of the wire () and to provide a protective layer over the wire reinforced area. The mesh or net fabric wrap tape () has periodic openings to allow penetration of polymer epoxy resin (). A top coat of a UV resistant polyurethane paint () has been applied.

A laminate composite structure is provided in continuous lengths or rolls for making an unvulcanized carcass for a radial ply pneumatic tire as an intermediate article of manufacture. The laminate has a ply and a plurality of elastomeric components hot formed and attached directly to the ply. Each component has a predetermined cross-sectional profile. The elastomeric components including, but not limited to, a liner, a sidewall, and a chafer. Additional other elastomeric components for the carcass can be formed and attached to the laminate structure. The laminate forms an intermediate article of manufacture that at a later stage of tire building can be cut to length and spliced along common ends to form a cylindrical carcass structure.

A method for securing splices in uncured rubber articles prior to vulcanization and secured splices resulting therefrom. The method includes covering a splice and two ends of uncured rubber with syndiotactic 1,2-polybutadiene, adhering the syndiotactic 1,2-polybutadiene to the uncured rubber adjacent to the splice, and curing the rubber. The rubber compound to which the syndiotactic 1,2-polybutadiene is adhered does not have to contain syndiotactic 1,2-polybutadiene. In addition, because the syndiotactic 1,2-polybutadiene is preferably melted into the rubber compound, there are no uniformity problems caused by the additional layer over the splice.

This invention pertains to a method and for cutting an intermediate article of manufacture, the intermediate article of manufacture being a cord reinforced elastomeric laminate. The laminate when cut to length, becomes a carcass for a pneumatic tire. The laminate is cut by a cutting element at angles .theta. greater than 60.degree. relative to a normal plane (NP) perpendicular to a cord reinforced ply of the laminate and parallel to the cords to thereby create large substantially flat planar splice surfaces without significant deformation or precuring of the unvulcanized elastomeric materials. To facilitate this cut, the relative position of the cutting element and the ply is changed to an angle .beta., .beta. being less than .theta.. The ply is cut a short distance, at the angle .beta., to position the cutting element between two parallel cords. Then the cutting element is reoriented to the angle .theta. to complete the cut.

A thin gauge, fine diameter steel cord reinforced tire ply fabric 2 is lap spliced. The steel cord 1 has one or more filaments 9, and each filament has a percent elongation of over 2.5% and tensile strength of at least (-2000D+4400 MPa).times.95%, where D is the diameter of the filament in millimeters. For passenger and lightly loaded trucks the fabric 2 is manufactured using a preferred cord 1 which is a 1+5.times.0.18 mm cord spaced 14 ends per inch, and for heavier loaded vehicles such as light trucks load rated E or greater the number of cords 1 is increased to 28 ends per inch.

A method and apparatus for rapid exchanging of calender rollers 350,352 for a calendering apparatus 302 is disclosed. The apparatus 302 has two or more generally cylindrical calender rollers 350,352 which are clamped and supported at each end by a rotatable support 314,316. A pair of the supports 314,316 are axially aligned and movable relative to the other axially aligned support. The method of exchanging rollers 350,352 includes the step of unclamping a roller 350 or 352 by increasing the spacing between the first and second rotatable supports 314,316, removing the roller 350,352, and clamping a different calender roller 350,352 between the first and second supports 314,316 by decreasing the spacing between them and engaging the respective ends of the different roller 350,352 with the first and second supports 314,316. This apparatus and method greatly facilitates rapid calender roller changeover and is particularly useful in the tire building art.

An improved method for mounting an annular tread 1 onto a tire casing 2 is described. The improved method comprises the steps of expanding the tread 1 radially and encircling the expanded tread with a transfer mechanism 30. The transfer mechanism 30 has a means 90 for holding the lateral edges 5 of the tread 1 in the expanded condition independent of the center 6 of the tread 1. The means 90 for holding the lateral edges 5 of the tread 1 is accomplished without contacting the radially inner surface 7 of the tread 1. The transfer mechanism 30 has a means 92 for circumferentially clamping the central portion of the tread 1 to the casing 2. The transfer mechanism 30 with expanded tread 1 is centered over the casing 2. The means 92 for clamping the central portion 6 of the tread 1 is actuated while holding the lateral edges 5 of the tread 1 in the transfer mechanism 30. Then the lateral edges 5 of the tread 1 are released from the transfer mechanism 30 thereby transferring the tread 1 to the casing 2 while preventing entrapment of air between the casing 2 and the tread 1.
