Abstract: A reforming mandrel and a method of use reforming mandrel to reform glass are described. The reforming mandrel comprises an upstream portion, a downstream portion and an at least partially hollow interior. The upstream portion may have an intake inlet for fluid flow. The downstream portion may be axially spaced from the upstream portion. The downstream portion may have a flattened cross-section defined by flattened peripheral portions joined by curved peripheral portions. At least one curved peripheral portion may be made of porous material resistant to a temperature of at least 1000° C. The at least partially hollow interior may communicate with the intake inlet and the porous material.

Abstract: A method for bending a sheet of material into a shaped article includes providing the sheet of material. A reformable area and a non-reformable area of the sheet of material are heated to a first temperature range corresponding to a first viscosity range. The reformable area of the sheet of material is subsequently heated to a second temperature range corresponding to a second viscosity range. The reformable area of the sheet of material is reformed into a selected shape by at least one of sagging the reformable area of the sheet of material and applying a force to the sheet of material outside of or near a boundary of the reformable area.

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.

Abstract: A method of bending a glass sheet includes placing the glass sheet on a support and heating the entire glass sheet to a first viscosity. A band of heat is applied and translated along the selected region of the glass sheet in which a predetermined is to be formed over a time period to form the predetermined in the selected region. The band of heat sectionally heats the selected region to a second viscosity that is lower than the first viscosity. An actuated force is applied to the glass sheet to incrementally form the predetermined bend in the selected region according to the location of the band of heat in the selected region.
