ABSTRACT:
A glass ribbon conveying roll includes cylindrical outer tubular end portions having a plurality of high temperature thermal insulating discs secured thereon and an intermediate tubular portion. The hollow interior of the roll is filled with thermal insulating material. The thermal insulating material within the roll reduces heat transfer through the center of the ribbon and the discs prevent heat loss from the ribbon edges to maintain a relatively flat temperature profile across the ribbon as it advances through an annealing lehr.
