The Capstone TriSeal Carton Closing Machine accurately positions, closes and seals three-flap cartons at line speeds of 150 cartons per minute. The precision servo-driven carton positioning mechanism within the new system ensures reliable, repeatable high-speed production of high-quality consumer packages at profitable production line speeds. Patent-pending technology aligns the leading edge of the carton and the scored foldover front flap during sealing to consistently produce a symmetrical sealed carton that perfectly aligns graphics to maintain a high-quality brand image. The machine’s efficient servomotor technology enables both positive carton transfer and quick and reliable changeovers between carton sizes, while the system’s right-angle design results in a compact footprint that conserves valuable facility floor space. The machine is constructed of stainless steel.
