E40 – HOLD-DOWN ROLLERS
They are used to fasten the belt to the conveyor in all the inflexions.
In applications in which the belt must be submerged, they are placed in the middle of the belt to prevent it from getting bent due to the flotation.
They will roll along rails fastened throughout the conveyor structure. It is recommended to place wearstrips to avoid the wear owing to rolling as far as possible.
The distance between the side edge of the belt and the centre of the hold-down roller (indent) must be a multiple of 5 mm.
