Abstract
A process for manufacturing a fiber optic display screen is disclosed where a fiber is guided onto a revolving drum and disposed into input and output clamps located on the surface of the drum. The fiber guiding device allows the fiber to be precisely located on the surface of the drum in a hexagonal offset pattern in corresponding locals in the input and output clamps. The strand is continuously guided over several layers of long thin rectangular slotted spacers until the desired height of the display is created. The fibers between the output spacers are then cut to form two or more rectangular or square shaped fiber optic display screen apparatus. Large display screens can be constructed by placing several sections of these display apparatus together.
