Multi-layer slot die system and method

A multi-layer slot die, comprising:

• a center body member having an upper center surface, a lower center surface, and a center rear surface;
• an upper body member adjustably coupled to the center body member, the upper body member having an upper surface and an upper rear surface, the upper surface being spaced apart from the upper center surface forming a first channel therebetween, the first channel including a first opening at a dispensing end of the multi-layer slot die configured to dispense a first fluid and a first inlet spaced apart from the dispensing end, the upper body member being configured to move between a first position and a second position, wherein in the first position the upper surface is spaced apart from the upper center surface by a first distance, and wherein in the second position the upper surface is spaced apart from the upper center surface by a second distance that is different from the first distance, wherein the first opening is substantially parallel to both the center rear surface and the upper rear surface in both the first and second positions of the upper body member;
• a lower body member adjustably coupled to the center body member, the lower body member having a lower surface and a lower rear surface, the lower surface being spaced apart from the lower center surface forming a second channel therebetween, the second channel including a second opening at the dispensing end configured to dispense a second fluid and a second inlet spaced apart from the dispensing end, the second opening being substantially parallel to the first opening and the lower rear surface in both the first and second positions of the upper body member;
• a first offset block coupled to the center rear surface, the first offset block being spaced apart from the upper rear surface;
• and
• a second offset block coupled to the lower rear surface, the second offset block being spaced apart from the center rear surface.
