ABSTRACT:
In a low tension spiral conveyor belt system, driving assistance is provided between the driving cage or capstan and a plastic conveyor belt via ridges formed generally vertically on the bars or caps on the cage bars. These ridges, preferably rounded at their exterior surfaces, interact with grooves provided in inner edge members of the belt, or with gaps between successive edge members. As the belt progresses up the spiraling incline of the system, the drive capstan ridges seat in belt grooves or gaps for a short period of time, assisting in driving engagement, then advance forward out of the groove due to the overdrive relationship of the capstan to the belt.
