Abstract

Apparatus and method for affixing rigid transparent windows to folding cartons draws rigid window web material from a roll and scores and notches the window material in a continuous manner. Notch waste is removed and collected for disposal by the combination of vacuum and an air jet applied at the point of severance. The transparent window material is then provided to an accumulator and then to a stop-and-go adhesive application and material cutting stage, where adhesive is applied to the material which is cut into individual rigid window patches, with the accumulator serving as a buffer between the high speed continuous scoring and notching stage and the stop-and-go adhesive application and cutting stage. Adhesive-bearing individual window patches are applied to moving folding cartons with registration between the notches and cut lines as well as between the cut window blanks and carton blanks provided by a control system.
