Abstract
The invention is related to the formation of three different and repeated stripes abbreviate as ABCABC-typed or A_B_C-typed at the die exit. The symbol, '_', implies that there is no coating between two adjacent stripes. In this invention a guide shim and a guide die are inserted between two coating dies. Three different coating solutions will flow into the die assembly through different inlet positions. Two of which are introduced from the two coating dies will flow through the multiple channels provided in the guide shim and the guide die respectively and then contact with each other and with the third solution introduced from a side of the guide die in the same slot section to form the ABCABC-typed stripes. The coating solutions can also flow through the multiple channels to the same slot section but not contact each other to form the A_B_C-typed stripes at the die exit with a modification of the die assembly.
