Weighted skate wheels were being used in a case sealer application which caused the center of the box to compress and thus not seal very well. So Brian Hester of AEC and Omni Conveyor, put together an idea of this adjustable dual belt conveyor that will allow the customer to adjust both the height of the opening as well as the width internally. Both belts are ran from a single drive unit with a pulley system and on the outside is a gauge so the operator can easily tune the height before the run of product. Top belt is Teflon coated to try and keep the glue buildup down and both are v guided belts.
