Method of and apparatus for coating fabrics
Abstract
Abstract Method and apparatus for applying coatings of thermoplastic or thermosetting resins in a predetermined pattern on one face of a traveling web. The apparatus includes a hollow rotating drum which is perforated is a desired pattern and into which is metered the resin to be applied to the traveling web. The web is held in engagement with the outer periphery of the rotating drum by a traveling belt or any other convenient arrangement which can assure passage of the web in contact with the drum at the same speed as the peripheral speed of the drum. Located interior of the drum is a baffle structure which limits the movement in response to rotation of the drum of the resin and assures that the coating of resin applied to the web through the holes in the drum is of constant thickness. After the web leaves its engagement with the rotating drum, the powdered resin is heated to cause it to sinter and to adhere to the web.
