DEVICE FOR WORN PNEUMATIC TIRE COVER GRINDING Russian patent published in 2006 - IPC B29B17/04 B29K21/00 

FIELD: rubber article utilization, particularly tire cover grinding.

SUBSTANCE: device comprises cover transportation mechanism supported by base, which conveys tire cover to compaction and supply mechanism for tire cover compaction and supply to grinding station, as well as grinding station. Cover transportation mechanism is made as sliding carriage with annular roller conveyer installed on the carriage and tire cover centering unit to align cover with typical cover dimension measuring means, which measures inner or outer tire cover diameter, and adapted to provide cover positioning with respect to compaction and supply mechanism. The compaction and supply mechanism is made as two profiled rollers, namely support-driving roller and pressure roller having power drive. Grinding station is made as drum with inserted teeth cantilevered from outer cylindrical drum surface. Teeth order provides serial cutter cooperation with compacted tire cover during cover grinding operation. Linear cutter speed is from 30 m/s to value defined by drum strength characteristics.

EFFECT: possibility to recycle tire covers having different dimensions, increased productivity.
