A sealing assembly attachment, for use in preparing envelopes which will apply a gum to a top flap, place a piece of release paper over the gummed flap, fold and crease the top flap and deliver the envelope to be stacked and counted. The sealing assembly attachment generally consists of a transfer cylinder to transfer envelopes into the sealing assembly attachment, a vacuum cylinder within the sealing assembly attachment to transport envelopes from the transfer cylinder and through the sealing assembly attachment, a gum pattern applicator to apply gum to a top flap of the envelopes while being transferred by the vacuum cylinder, a release paper applicator after the gum pattern applicator to place release paper over the gum applied to the top flap, a flap fold cylinder used in cooperation with the vacuum cylinder to fold and crease the top flap; and a delivery disk to transfer the envelope from the sealing assembly attachment to a delivery table to be stacked.
