Douglas Machine Inc. added a new horizontal case/tray packer to its line of packaging machinery. The Invex IM offers an economical, high-performance solution for mid-range case packing applications to pack cartons, bundles, cans and bottles into corrugated cases and trays at rates of up to 80 cases a minute, the company says. Featuring a methodology that eliminates the use of less efficient air cylinders and the plowing of flaps, the machine is able to maintain precise control over flap folding, case squaring and glue compression, resulting in higher quality cases and greater reliability, it says. The machine also is flexible and easy to changeover for a wide range of products and case sizes, it adds.
