Abstract
A dust and fiber control device for paper making apparatus is described. The device includes a wall in conjunction with a feed spout for providing a water curtain. The water curtain serves to capture and remove air suspended dust and fiber particles from ambient air. The device is positioned transversely to the motion of a paper web underneath the web between a drying cylinder and a rewinder. The water curtain device is utilized in conjunction with air flow devices for assisting in controlling the collection of air suspended dust and fiber particles from the ambient air.
