Packaging

Machine builders face a vexing problem when there’s a need to rotate large or unwieldy products in assembly, handling, and packaging applications. Engineers often must select and size an electric motor; evaluate direct, belt, or gear drives; find bearings that can handle the loads and give long life; and assemble the entire package and fit it into often-limited space. A better option may be a guided pneumatic swivel module that provides a versatile, rotating drive for large and hard-to-handle loads....More

Packaging-equipment manufacturers continue to push the engineering envelope to add more features to their machines and run them at higher speeds. Case in point is the recently introduced SD-900 from Glue Dots International based in New Berlin, Wis. The SD-900 is a fully automated adhesive applicator designed to quickly and cleanly apply the company's proprietary pressure-sensitive adhesives. It's suited for general packaging applications, as well as for specialized use in the pharmaceutical, nutraceutical, cosmetic, and printing industries....More

Despite some open air flow, simple devices such as check valves and flow restrictors help suction cups keep a tight hold on products....More

When a packaging-equipment manufacturer wanted to make a basic, relatively low-cost meat packing machine with a fairly high degree of precision and automation, the company’s design engineers found that air motors, not electric motors, provided the best po...More
