  • Patent number: 5009693
    Abstract: A batch method and apparatus for bending glass sheets includes an oven where the glass sheet is oscillated back and forth on mini-rollers until it reaches a hot, softened condition, at which point the vertical position of the rollers is changed so that the top surface of the rollers have the contour of a desired bent glass sheet. The hot glass sheet conforms to the contour of the rollers and is quickly transferred to a quench section for quenching. The quench section includes rollers and quench tubes which have the same contour as the bent glass sheet.A continuous method and apparatus for bending glass sheets includes an oven having a heating section where a glass sheet is heated to a hot, softened condition while being conveyed on full faced rollers, and a bending section having minirollers which support the flat glass sheet and then change in vertical position to the contour of the desired bend for bending the hot, softened glass sheet.
