Abstract
Abstract A method of making a tire of the type having radially disposed reinforcing cords in the carcass and a restrictive belt or girdle superposed thereon, characterized by the belt or girdle being formed as a circumferentially continuously wound strip of parallel cords disposed in a plurality of sinusoidal windings alternately tangent to opposite axial edges of the belt.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
The method of making a pneumatic tire comprising: a. providing a carcass of at least one ply of radially extending cords, and axially spaced beads in a substantially toroidal configuration; b. superposing on the crown region of said carcass a tread reinforcing belt wound from a tape comprising a plurality of parallel cords covered with elastomeric material, the said tape 1. having a width substantially less than the width of the belt, 2. being disposed in a plurality of sinusoidal windings such that each change of direction of the tape winding is effected in a flat curve at an edge of the belt with the tape disposed tangentially to the adjacent belt edge, and 3. the half period of the sinusoidal winding being not less than one-twelfth nor more than one-third of the circumference of the complete tire; c. applying uncured elastomeric material over said belt and carcass to form a tread and sidewalls; and, d. vulcanizing the tire in a mold.
Claim 2
Independent Claim

Claim 3
Dependent Claim
41 words
being disposed in a plurality of sinusoidal windings such that each change of direction of the tape winding is effected in a flat curve at an edge of the belt with the tape disposed tangentially to the adjacent belt edge, and
Claim 4
Dependent Claim
41 words
being disposed in a plurality of sinusoidal windings such that each change of direction of the tape winding is effected in a flat curve at an edge of the belt with the tape disposed tangentially to the adjacent belt edge, and
Claim 5
Independent Claim
148 words
The method of making a pneumatic tire comprising: a. providing a carcass of at least one ply of radially extending cords and axially spaced beads in a substantially toroidal configuration; b. rotating said carcass about its axis and simultaneously oscillating the carcass about an axis at right angles to the axis; c. winding on the crown of said rotating and oscillating carcass a tape of elastomer covered cords, which tape has a width less than the lateral extent of said crown, the winding being effected in unfolded overlapping sinusoidal configuration thereby forming a continuous band with each reversal of direction of the tape tangent to an edge of the band and with the half period of the sinusoidal winding being not less than one-twelflh nor more than one-third of the circumference of the complete tire; d. applying tread-forming elastomer over the said band; and e. vulcanizing the tire.
