Multi-Conveyor, Winneconne, Wis., developed the new Helix Upender, also known as a "twist-"style conveyor, typically used to change product orientation by 90 or 180 degrees, clockwise or counter-clockwise, to facilitate inkjet printing, labeling, case packing or even hand-pack operations.
Constructed with two table-top chains set at 90 degrees, products enter the system supported on the bottom chain. As they transport, the two chains simultaneously twist, causing the product to rotate.
