ABSTRACT:
A side plate for a modular plastic conveyor belt for use in a spiral conveyor belt system has one or more generally vertical grooves formed in its outer side, for engagement with protruding structure of cage bars of a spiral conveyor driving cage. At least one of the grooves is positioned on a common center with a countersink bore which receives a plastic rod head of a connecting rod in the modular conveyer belt. In cooperation with the side plate grooves are bumps or protrusions on the cage bars of the driving cage. These may be formed in cage bar caps which are assembled onto the exterior of the cage bars. At least some of the bumps on the cage bars are at any one time engaged in side plate grooves, providing assistance in the driving of the spiral conveyor belt by the driving cage.
