ABSTRACT:
A laminator system for the continuous treatment and lamination of a plurality of flexible webs, with the system including the conventional adhesive applicator stations and laminator stations, with a drying chamber being arranged to dry or otherwise condition the applied adhesive films. The drying chamber is an annular enclosure having a generally inverted "U" configuration with access openings being formed at the base of each of the upright legs. Guide rolls are provided for creating a plurality of web paths through the laminator system, with the web paths including a plurality of generally parallel and concentric spans extending through the drying chamber. In addition to size reduction considerations, the drying chamber provides enhanced versatility for the laminator assembly, and simplifies solvent recovery.
