A preformed strip ( ) of unvulcanized rubber having a plurality of strand receiving grooves ( ) for splicing the ends ( ) of steel cord or strand reinforced rubber conveyor belts ( ) is disclosed along with a method of forming the spliced joint.

Preformed strip and method for splicing conveyor belts

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.

An aircraft tire having a liquid deflector extending outwardly from at least one sidewall, a first plurality of grooves in the tread and a second plurality of grooves disposed axially outwardly of the tire relative to the first plurality of grooves for directing water from the first plurality of grooves toward the respective liquid deflectng means. The first plurality of grooves may interconnect to direct water to the second plurality of grooves each of which may extend at an angle of between about 25 and 35 degrees relative to a radial plane of the tire passing through the respective groove.
