Abstract
A deformation apparatus for reforming a glass sheet comprises a central portion, a first edge mold movably coupled to a first end of the central portion and configured to be linearly translated along a linear mold axis in a first direction toward the central portion. The deformation apparatus further includes a second edge mold movably coupled to the second end of the central portion and configured to be linearly translated along the linear mold axis in a second direction opposite the first direction and toward the central portion. Methods are also provided including the step of cooling a reformed glass sheet, wherein a greater shrinkage of the reformed glass sheet relative to a shrinkage of the deformation apparatus is accommodated by a movement of at least the first edge mold in a first direction toward the central portion of the deformation apparatus.
