Abstract
A slot coating die (10) is provided, comprising an upper die half (12) and a lower die half (14) attached together with a shim (16) disposed therebetween, each die half extending along an axis (18) and having a front and a back. The front of the upper die half includes a movable lip insert (22) extending substantially the entire width thereof and movable with respect to the upper die half toward and away from the front of the upper die half in a direction generally perpendicular to the axis. At least one adjustable die opening (20), which is adjustable independently of the movable lip insert, is defined by the upper and lower die halves and the shim plate disposed therebetween. A plurality of push-pull bolts (30) provide a coarse adjustment mechanism for adjusting the relative positions of the lower and upper die halves with respect to each other in a direction generally parallel to that in which the movable lip insert may be moved. A plurality of springs (128) loaded screws (124) spaced along the width of the upper die half provide a fine adjust mechanism by which the lip insert is made movable in that direction.
