Constructed with two (2) Table Top chains set at 90 degrees to each other, products enter the system supported on the bottom chain. As they are transported, the two chains are simultaneously twisted, causing the product to rotate.
Helix upenders are also used for hand pack operations to rotate the product going into a secondary package, or to rotate the case so the product can be more easily inserted inside the case. These units readily accept multiple size products without the need for changeover.
