Abstract
A die includes an upper body member and an adjustment system. The upper body member has a upper surface, a gap surface, a gap edge positioned between the upper surface and the gap surface, and a gap flange. The adjustment system includes an adjustment body that defines a plurality of channels, and a plurality of adjusters. Each of the plurality of adjusters is slideably positioned within a respective one of the plurality of channels. Each of the plurality of adjusters is configured to couple to the gap flange of the upper body member. When the plurality of adjusters are coupled to the gap flange movement of the plurality of adjusters causes a change in a position of the gap edge.
