Intralox’s patented DirectDrive™ System engages the belt edge directly with the drum to eliminate overdrive and ensure that the spiral operates with zero slip. This technological breakthrough is engineered to minimize operational and maintenance downtime and to reduce belt tension, labor, and cleaning costs. In conventional friction-driven spiral systems, the central drum rotates slightly faster than the belt. This is known as overdrive. The belt is driven by friction against the central drum, which requires constant controls tweaks and causes some movement of the belt close to the drum that leads to mis-orientation of products on the belt. Also, any variations in friction–e.g. butter–disturb the operation of the spiral. In the DirectDrive System, the belt is directly driven by the drum, which acts like a central sprocket.
