  • Patent number: 7975581
    Abstract: The apparatus for cutting glass panes from a continuously produced glass sheet includes a conveying apparatus for the glass sheet and for crosscut pieces; a crosscutting device for cutting the crosscut pieces from the glass sheet; a glass pane cutting device for cutting glass panes from the crosscut pieces; a glass fault detecting device; a border trimming station for cutting away borders; an edge control device and a cutting optimization device. The cutting optimization device determines one or more optimized cutting patterns so that cutting lines are placed in each crosscut piece close to regions to be discarded containing glass faults so that widths of the regions are minimized while providing a maximum number of usable glass panes. A method of cutting off glass panes so that the discarded glass sheet regions are minimized is also disclosed.

  • Patent number: 7963200
    Abstract: The method includes continuously detecting glass faults in the glass sheet. Based on the results of the detecting of the glass faults an optimized cutting pattern for cutting crosscut pieces from a predetermined sheet section and for cutting glass panes from the crosscut pieces is determined. In order to reduce waste, the cutting lines for the glass panes are placed sufficiently close to fault-containing glass sheet regions, so that the glass sheet regions to be discarded are minimized, while producing a largest possible number of usable glass panes. The crosscut pieces are then cut out according to the optimized cutting pattern and then the glass panes are cut from the crosscut pieces. An appropriate apparatus for performing the method is described.

  • Publication number: 20050023337
    Abstract: The method for cutting off glass panes from a continuously produced glass sheet includes continuously testing the glass sheet for glass faults prior to the cutting off process and determining glass sheet regions to be discarded containing the glass faults. Based on the test results for the glass faults an optimized cutting pattern for a predetermined glass sheet section is calculated in a cutting optimization device, which is a plan for cutting the glass sheet section into crosscut pieces, in which glass panes of respective sizes are arranged next to each other in corresponding crosscut pieces. In order to reduce waste, the cutting lines for the glass panes to be cut away within each crosscut piece are placed sufficiently close to the fault-containing glass sheet regions, so that widths (BS) of the glass sheet regions to be discarded are minimized or the glass sheet regions to be discarded are minimized, while accounting for a largest possible number of usable glass panes.
