Abstract:
1. A coating die apparatus comprising: a die having a Z-dimension die width distance to X-dimension die distance and/or Z-dimension die width distance to Y-dimension die distance ratio greater than 2.5, and a mechanically suitable operating temperature, die lip faces in a Y-Z plane and a slot opening perpendicular to the die lip faces in an X-Z plane, the die lip faces forming the slot opening at a front portion distal from the rear portion, a coating gap being formed between the die lip faces and a substrate upon which a fluid layer is applied onto the substrate from the slot opening across the Z-dimension die width distance; and an integrated heating system for maintaining bending flatness of the die lip faces in the Y-Z plane and in the X-Z plane, the integrated heating system having:
