  • Publication number: 20240092677
    Abstract: A method of shaping a glass sheet includes providing a glass sheet. The glass sheet is heated to a temperature suitable for shaping. The glass sheet is deposited on a first bending tool. The glass sheet is disposed over a first segment of the first bending tool. The first segment at least partially defines a shaping surface of the first bending tool. The first segment of the first bending tool is moved from a first position to a second position to cause contact with a first portion of the glass sheet. The contact with the first portion of the glass sheet adjusts a position of the glass sheet relative to the shaping surface of the first bending tool. The glass sheet is shaped on the first bending tool.
