Free Brochure Improves Rotary Side-Seam Gumming Operations
Key variables affecting quality and consistency in rotary side-seam gumming are addressed in a new, complimentary four-page color brochure from National Adhesives, Bridgewater, N.J. These issues include extreme viscosity changes, which affect gum transfer, application and machining.
The brochure explains how to avoid problems by focusing on the gum’s formulation and viscosity, various factors of the gumming machine and steady supply to the gum box. For the most effective operation, the rotary side-seam gum must retain moisture and minimize foaming, and the brochure identifies the specific formulation that meets these requirements. The gum also must feature an ideal viscosity measurement—defined in the publication, along with suggestions for diluting.
