ABSTRACT:
A dual drive conveyor system with improved traction in which two drive pulleys are rotatably coupled together by two drive wheels with one of the drive wheels comprising a resilient deformable wheel and the other comprising a smooth non-deformable wheel. The outer surfaces of the drive wheels permit minor slippage therebetween to compensate for differences in peripheral velocities of the drive wheels and minimize wear of the conveyor belt, drive wheels and drive pulleys.
