Abstract
Window panels are cut in sheet material by means of a rotatable panel cutter and the sheet material is thereafter conveyed to a location adjacent a panel or chip receiving means. A negative pressure is applied to the underside of the sheet, the cut panel or chip is conveyed away from the sheet by the negative pressure. Turnaround rollers are provided for the sheet material. Where the panel is not completely severed from the sheet, a portion of the panel will be deflected by the turnaround roller and a blade is positioned adjacent the turnaround roller to engage the panel and remove the panel from the sheet. Air blast means are provided in overlying relation with the web above the panel receiving means to dislodge the panel from the sheet so that the air blast means will also dislodge the severed panel in the sheet passing between the panel receiving means and the air blast means.
