Abstract
A reformable area and a non-reformable area of a sheet of glass material are heated to a first temperature corresponding to a first viscosity. The reformable area is subsequently locally heated to a second temperature corresponding to a second viscosity, where the second viscosity is lower than the first viscosity. A bend is formed in the reformable area during the local heating of the reformable area by contacting a first pusher with the non-reformable area and translating the first pusher along a linear path to apply a pushing force to the non-reformable area that results in the bend in the reformable area or by contacting a second pusher with an edge area of the reformable area and rotating the pusher along a circular path to apply a pushing force to the edge area of the reformable area that results in the bend in the reformable area.
