Method and apparatus for forming fine lines by means of curing coating

A method for forming fine lines by means of a curing coating, comprising:

• (1) spreading a curing coating onto one face of a carrier intermittently and forming first spread zone and vacant zone in which the length of said first spread zone is longer than one half of the circumference of a first impressing wheel and lines are disposed on the outside of said first impressing wheel;
• (2) pressing at least one pressing wheel from another face of the carrier toward a first impressing wheel to cause said first spread zone of said carrier to be stuck tightly with said first impression wheel to allow lines corresponding to said lines of said first impression wheel to be formed on said first spread zone and then hardening the lines by the energy emitted from an illumination emitting source to have a first lines zone intermittently;
• (3) spreading vacant zone of said carrier and the two adjacent first lines zone of each vacant zone with said curing coating to form second spread zone, wherein the length of said second spread zone is also longer than on half of the circumference of said first impressing wheel, the both ends thereof has the overlapped zones over said adjacent first lines zones;
• and
• (4) pressing at least another one pressing wheel from another side of the carrier toward said second impressing wheel to cause said second spread zone to be stuck tightly with said second impressing wheel to allow lines corresponding to said lines of said second impressing wheel to be formed on said second spread zone and then hardening the lines with energy from another emitting source to cause said second spread zone of said carrier to be formed to a second lines zone, in which an overlapped zone of said first lines zone and said second lines zone formed by said first spread zone and said second spread zone of said carrier respectively impressed by said first impressing wheel and said second impressing wheel has same lines so that continuous lines are caused to form on said overlapped zone of said first lines zone and said second lines zone to form continuous non-slit lines.
