Packaging-equipment manufacturers continue to push the engineering envelope to wring higher speeds and more features out of their machines. 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.
The web-fed, inline applicator incorporates a number of sensors and stepper motors that let it run at high speeds with precise, coordinated motion control. But it all comes together thanks to a pneumatic cylinder from Numatics Inc., Novi, Mich.
The SD-900 applies pressure-sensitive adhesive a feed rate of 300 pieces per minute.
When in close proximity to a product, a web-fed machine, such as a label applicator, typically uses a motor to accelerate the web and apply labels onto passing products....
