The invention comprises a die apparatus including a flexible lip for adjusting a gap between the flexible lip and a second lip. The apparatus includes a rotating shaft that cooperates to move the flexible lip. The rotating shaft may communicate with linear moving members to move the flexible lip. The apparatus may also include a cross-bar contacting the lip and extending substantially the length of the lip, where the cross-bar is connected to the linear moving members that are moved by the rotating shaft. As a result, the dimensions of the gap may be changed by moving the rotating shaft in a first direction or a second direction.
