Delkor Capstone Tri Seal Carton Closing Machine

The Delkor Capstone Tri-Seal Carton Closing Machine features Intelligent Positioning™ technology to consistently align sealing flaps and carton graphics during high-speed operation, resulting in superior package quality. Tool-less changeover, precision belt drives, and ease of access for cleaning and maintenance sets new levels of operating efficiencies to this class of carton closing system.

The engineering team at Delkor was the first to figure out how to analyze the position of each carton at speeds up to 150 cartons per minute, and make the precise corrections should a deviation occur. With Delkor’s Intelligent Positioning Technology™, the Delkor Capstone Tri Seal Carton Closer offers a new level of carton forming precision, and it is the only carton closer in the world with this important new technology.
