Abstract

Abstract Apparatus for closing an article wrapper that has a lower tubular portion integrally formed with an upper flap. The apparatus includes a horizontally extending frame having an entrance section and a conveyor section with the former having a rail for maintaining the flap spaced from the tubular portion as the wrapper moves toward the conveyor section. The conveyor section has a power-operated flap depressor that serves to move the lower edge of the flap into position for bonding engagement with the tubular portion while the wrapper is being moved by an endless belt towards the exit end of the apparatus.
