<p>The invention pertains to cutting irregularly shaped glass parts from glass blanks, and providing interior openings or cutouts in the parts, at a relatively high volume. Glass blanks are conveyed one-by-one to a transfer position beneath a shuttle carrier. The shuttle carrier picks up each sheet by means of vacuum cups and transfers it to the table of a cutting machine. A plurality of ganged abrasive jet cutting heads follows a prescribed path to cut a corresponding plurality of parts from the blank. The cutting heads then trace a second prescribed path to provide an interior cutout in each part. The ganged cutting heads may make additional passes to cut additional nested sets of parts from the blank. Upon completion of cutting, a second shuttle conveyor moves into position over the cutting table and, by means of vacuum cups thereon, picks up the individual parts and cutout portions and transfers them to a run-out conveyor for subsequent fabricating steps. The cutting machine table tilts upwardly to deposit the remaining selvedge from the blank in an adjacent cullet receptacle.</p> |
