Abstract: A method for automatically detecting and adjusting the position of a plurality of burners with respect to the edge of a continuous glass sheet is provided. The glass sheet is transported by rolls along the length of a thermal treatment lehr. Detecting and adjusting sensors for sensing the edge of the glass sheet are attached conjointly with the burners in order to automatically adjust the position of the burners with regards to the edge of the glass sheet, so, for each variation in the width of the glass sheet, the detecting and adjusting sensors are advanced or retracted over the edge of the glass sheet, in order to adjust the burners in accordance with a new position of the edge of said glass sheet.

Abstract: A system for detecting and automatically adjusting the position of a plurality of burners with respect to the edges of a continuous glass sheet is provided. The glass sheet is transported by rolls along the length of a thermal treatment lehr. Sensor elements for sensing the edge of the glass sheet are attached conjointly with the burners in order to adjust the position of the burners. A programmable controller is coupled to the sensor elements in order to adjust the position of the burners in accordance with the position of the sensor elements at the edge of the glass sheet.

Abstract: A glass sheet handling apparatus for horizontally receiving a glass sheet from a roller conveyor and placing the sheet vertically on a pyramidal conveying shelf comprising a discharging platform at the end of the conveyor to receive a glass sheet; an angular member having a first end pivotally joined to the platform and a second end pivotally anchored to a support structure; a fluid operated cylinder and piston assembly having its cylinder pivotally anchored to the support structure and its piston pivotally joined the angular member; and a controller to control the operation of the fluid operated cylinder and piston assembly, so that when the piston is actuated, it lifts the angular arm and the discharging platform with the glass sheet thereon, from a horizontal position through a path defining an arc to a vertical position, thereby vertically positioning the glass sheet on the pyramidal conveying shelf.
