A dynamic balancer includes a support frame with a frame plate that has a spindle opening through which a spindle assembly with a rotatable spindle shaft is received. A sensor plate is coupled to at least the support frame, and at least one force sensor is coupled between the sensor plate and the spindle assembly to detect force variations therebetween as the rotatable spindle shaft rotates. A related method for detecting a balance condition of a tire includes providing a plurality of force sensors maintained in a substantially horizontal plane with respect to the tire's rotation, chucking and inflating the tire, spinning the tire to a predetermined speed, generating force data from the plurality of force sensors, calculating an imbalance condition from the force data, and marking the tire at a location of imbalance if the imbalance condition exceeds a predetermined threshold.

Dynamic balancer

The method of folding overlap side edges of a wide breaker ply over side edges of a narrow breaker ply wrapped around the wide breaker ply on circumferentially spaced modules wherein the modules have axially movable belt lifting and conveying nose members to carry the overlap side edges of the wide breaker ply axially over the side edges of the narrow breaker ply and position the wide side edges of the wide breaker ply over the narrow breaker ply side edges. The nose members are then retracted to peel the belt away from the folded overlap side edges of the wide breaker ply.

Method of folding tire breaker ply edges

Circumferentially spaced folding modules of a tire building drum have axially movable belt lifting and conveying nose pieces which carry wide breaker ply edges over narrow breaker ply edges laid on the drum.
