W.H. Leary Company offers gluing and quality assurance solutions for the demands of the specialty corrugated box market. Leary’s gluing and quality assurance solutions focus on the rising demands of e-commerce packaging consisting of high quality graphic corrugated boxes produced on Specialty Folder Gluers.

Leary’s patented solutions guarantee every box is inspected by each detection station on the folder gluer. The new Sempre-i cold glue valve and UV40 glue detection sensor ensures +/- 1 mm accuracy. The slim valve design is equipped with adjustable mounting hardware and heavy duty guides for precise product containment. Choose dual Sempre-i valves for increased application and stronger adherence. Application patterns and detection can be controlled individually or combined for efficient glue savings and precise tolerances. Detect for glue presence, placement and volume with ease, set up detection and make fine-tune adjustments remotely. Monitor for mixed copy and verify customer code readability at 2,000 scans/sec, reading each code multiple times to guarantee reliability.

Guarantee box quality with missing or dropped flap detection. This solution monitors absence and presence of flaps, inspects for hanging scrap and correct cut outs as well as detecting dropped 45° crash lock or 4/6 corner flaps. Reliable rejection devices ensure that defective products are correctly identified for delivery of 100% quality product to your customer.

Leary also offers a complete pressure sensitive adhesive and silicone release liner solution to converters producing e-commerce and other mailing products. Using the Robatech FK IT coating head along with either Enpro or Straub tape applicators and a simple controller, Leary offers solutions for high-speed, long run and cost-effective short run applications. Package options include: Concept hot melt tank, FK IT coating head, iTac IR-2L hot melt detection, tape applicator and controller. Improve packaging services offered to your customers with these silicone release liner options.
