Abstract:
A method of manufacturing patterned glass sheets having a visual appearance simulating an appearance of conventional glue chipped glass sheets, the method comprising the steps of:providing a furnace or melter; providing first and second opposing rollers which define a nip therebetween, and providing at least one of the first and second rollers with a glue chipped simulating pattern comprising a plurality of intersecting ridges of different lengths defined in an exterior surface thereof, wherein a plurality of the ridges intersect one another at angles of from about 5-80 degrees; a ribbon of glass exiting the furnace or melter and proceeding toward the nip; the ribbon of glass reaching the nip between the first and second rollers at a temperature of from about 1,900-2,400Â° F.; forming a glue chipped simulating pattern in at least one surface of the glass ribbon in the nip, by causing the glue chipped simulating pattern to be transferred from the at least one roller to the ribbon of glass; the patterned glass ribbon exiting the nip; annealing the patterned glass ribbon after the ribbon has left the nip; and cutting the patterned glass ribbon into a plurality of sheets which simulate conventional glue chipped glass sheets from a visual perspective.
