In an automatic ply applier having a support means, ply stock supply means mounted on one end of said support means, a shaft mounted on the other end of said support means, a tire building drum mounted on said shaft, belt drive rings journaled on said shaft for rotation thereon, a plurality of rollers mounted on said support means, an idler roll mounted on said belt rings for rotation therewith around said shaft, an endless conveyor means mounted on said support means and trained about said rollers and said idler roll, one of said plurality of rollers being moveable in a linear direction, and power operated means connected to said drum and said belt rings to selectively rotate said drum and said belt rings in synchronism for a first predetermined amount of rotation followed by the sole rotation of said drum a second predetermined amount, and said drum being in frictional contact with said endless conveyor means to transfer ply stock from said conveyor means to said drum upon continued rotation of said drum to effect a wrapping around of the ply stock resting on said conveyor means about said drum during actuation of said power operated means.
In an automatic ply applier having support means, ply stock supply means mounted on one end of said support means, a tire building drum mounted on the other end of said support means, a belt ring journaled on each end of said drum, drive means connected to said tire building drum and said belt rings for selectively rotating said drum and rings simultaneously and thence rotating said drum relative to said rings, an idler roller journaled for rotation on said belt rings and for arcuate movement therewith, a plurality of rolls mounted on said support means, endless conveyor belt means trained on said rolls and said idler roller for movement thereon, motive means operably connected to said endless conveyor belt means for moving said belt in an orbital movement, certain ones of said rolls mounted for linear movement on said support means and for rotation around said belt rings in cooperation with rotation of said idler roller with said belt rings to wrap a portion of said endless belt means about said drum by said drive means, cut-off means mounted on said one end of said support means for severing a predetermined length of ply stock on said conveyor belt means.
