Top Case Sealer
236 Series
Hot Melt Adhesive or Tape Sealing
The Model 236 is the compact case sealer that gives you more. It has a streamlined design, yet it’s packed with the quality features that make A-B-C sealers the gold standard of 24/7 reliability. It’s built to provide years of carefree service with the versatility to adapt to your changing needs.
A Compact Powerhouse Top Case Sealer
The Model 236 brings top performance to mid-range packaging lines. At just 8’ long, this sealer is a compact unit, but it’s no lightweight. It’s a true production machine with robust construction and quality production features that ensure consistent and dependable case sealing.
Square cases are ensured with production-proven technology that provides total case control from infeed throughout sealing. Both minor and major flaps are folded with gentle precision, accommodating corrugated variations, to deliver square, well-sealed cases for palletizing.
Key Features That Benefit Your Production

Quality construction for top performance and reliability
This case sealer's heavy gauge steel frame is welded and bolted for strength and vibration-free operation. The upper operating mechanisms are secured to the frame by a solid rack and gear system. Drive shafts are solid 1-1/4" steel.
Clear sliding guard doors enclose the machine, keeping your line operators safe while allowing full visibility of operation. Safety interlocks stop machine operation when the doors are opened to allow full access to the machine.
At only 8’ long including compression, this case sealer brings a new level of performance to the compact case sealer lineup.

Product feed and line speed fluctuations are easily accommodated
The metering roller infeed accepts cases from the line as they approach the sealer. Whether in random or back to back sequence, cases are spaced automatically in proper position to ensure precisely synchronized flap folding and sealing.

Reliable minor flap folding and case-squaring major flap closing
The trailing minor flap is closed by a reciprocating tucker that provides positive folding and ensures smooth major flap closing. The major flaps are smoothly folded precisely at the scoreline by contoured folders. This proven design is key to forming square cases.
The adhesive sealer has a steel tongue that rides between the flaps as they are folded, squaring the case and preventing flap overlap. The tape sealer employs a guide rail that squares the case during tape application.

NO-CRUSH compression rollers square cases as they seal
The adhesive sealer has an integrated compression section with flexible rollers that compress the case flaps securely. The flexible rollers provide full compression for cases of varying height and provide square, well-sealed cases that perform well at the palletizer, forming strong and stable pallet loads.
Easy access tape roll offers quick and easy refill
The tape system is quickly accessible for quick and easy roll replacement. The attendant simply replaces the tape roll and attaches the new roll to the tail of the previous one.
An optional “roll empty” sensor stops the sealer as the end of the tape leaves the roll.
