Super Air Knife Removes Loose Grains From Sandpaper

An abrasives manufacturer is producing sandpaper. It is a continuous web application where the grains are applied onto the web. The web is coated with a small amount of adhesive to hold the grains. Many of the grains do not contact the adhesive and are loose on the web. These fugitive grains need to be removed prior to a secondary coating process to cure the adhesive. An EXAIR Model 110036 36" (914mm) Aluminum Super Air Knife was installed to remove the fugitive grains. The manufacturer is now recuperating a larger amount of abrasive grains. They have cleaner packaging and a better quality product for the customer.
