  • Method and apparatus for transporting a substrate with adhesive
    Patent number: 6273976
    Abstract: An apparatus is disclosed for transporting panel substrates with adhesive on both sides such that the panel substrates may be used in the manufacture of decorative panels. The apparatus includes a adhesive applicator which coats a panel substrate with adhesive. The apparatus also includes a first edge support member and a second edge support member located adjacent an outlet end of the adhesive applicator such that edges of the panel substrate are respectively supported by the first edge support member and the second edge support member without interfering with the adhesive being applied to the panel substrate. The apparatus further includes a support for selectively supporting the coated panel substrate and releasing the panel substrate while only contacting edges of the panel substrate so as not to substantially interfere with the adhesive applied to the panel substrate by the adhesive applicator. A method for manufacturing a panel is also disclosed.
