Features and Benefits


Quality features

The Model 53 case sealer features all the quality components of standard A-B-C case sealers, including a machine frame that is welded and bolted for strength. Case flaps are closed with contoured cast aluminum flap folders for smooth folding. The compression section has top and bottom powered belt drives. The top compression belt is backed by spring-loaded rollers to accommodate variations in case height and ensure proper sealing.


Compact size

Even with its large case capacity, this case sealer is less than 14 feet long. The compression section length will vary.


Special features for oversized cases

An extra wide package plate is utilized to provide added support of the case contents as the  lower flaps are glued and sealed. A full width pusher bar transfers cases through the sealer, providing full support of the case contents.


Easy changeover

Case size changeover is simple. First, position a new case at the infeed and use the manual crank adjusts to fit the new case height and width. Adjustments may be made from either side of the sealer. Next, set the new adhesive pattern at the electronic adhesive timer. In minutes, the case sealer is back in production.
