US Patent 9745147 Glass sheet forming system

A system (10) for forming glass sheets includes a glass location sensing assembly (80) having a fluid switch (82) that is actuated by a roller conveyed glass sheet (G) to control operation of transfer apparatus (69) that transfers the glass sheet from the roller conveyor (22) to a forming mold (48) at a design position for forming. A frame of the sensing assembly (80) supports a carriage (124) on which the fluid switch (82) is mounted for lateral movement with respect to the direction of conveyance of the glass sheet (G) so as to sense its leading extremity. A lateral positioner (130) adjusts the lateral position of the carriage (124) and the fluid switch (82) mounted on the carriage.
