Two steam-heated batch ovens will be used for curing a water-based adhesive applied to rolls of sandpaper. The adhesive is needed for the sand to stick to the paper.

Manufactured by Wisconsin Oven, East Troy, Wis., the curing ovens have a maximum operating temperature of 300°F. They are capable of heating 35,000 lb of product from 70 to 240°F within a two-hour period and can cool the load down to 140°F within three hours.

Top-down airflow is distributed through the work chamber by factory preset nozzles, and jumbo suction fans are utilized to draw hot air through all the layers of the sandpaper rolls.
