Abstract
Exemplary embodiments of the present disclosure are directed towards methods and apparatus for molding-in gaskets that serve as light blockers, within the grooves of a moving planar work material. The gaskets comprise of a hot melt adhesive material that is in a molten state above a particular temperature and gets solidified below a particular temperature. Another exemplary embodiment of the present disclosure is directed towards a planar work material having grooves that are filled with molded-in gaskets, wherein the gaskets are made up of a hot melt adhesive material. The gaskets made of the hot melt adhesive material bond securely with the panels because of inherent adhesive properties, and provide structural stability to the light panels. Another exemplary embodiment of the present disclosure is directed towards the use of a hot melt adhesive material as the molding material for molding-in gaskets within the grooves of a planar work material.
