Abstract: A glass manufacturing apparatus includes a delivery apparatus defining a travel path extending in a travel direction. The delivery apparatus conveys a glass ribbon along the travel path in the travel direction of the delivery apparatus. The glass manufacturing apparatus includes a first forming roll and a second forming roll spaced apart from the first forming roll to define a gap. The first forming roll and the second forming roll receive the glass ribbon along the travel path within the gap. A drive apparatus is coupled to the first forming roll and the second forming roll. The drive apparatus moves one or more of the first forming roll independently of the second forming roll or the second forming roll independently of the first forming roll to change a width of the gap.
