Abstract:
1. A device for co-extruding first and second materials onto a substrate such that the first and second materials form parallel elongated gridline structures on the surfaces of the substrate, each said gridline structure including a central line structure formed by said first material that contacts the surface of the substrate, and support structures formed by the second material that contacting opposing side surfaces of the central line structure, the device comprising: a housing defining a plurality of exit ports and a plurality of inlet ports that extend through one or more outer surfaces of the housing, and a plurality of convergent paths defined inside housing, each of the convergent paths including: wherein the first and second side channels and the central channel of each said convergent path converge at the merge region such that when the first material is introduced into the central channel through the first inlet port and the second material is introduced into the first and second side channels through the second and third inlet ports, the first material and second material form a single flow in the merge region is sandwiched between portions of the second material to form said central line structure and said support structures before exiting said associated exit port.
