Apparatus and method for folding and sealing a mailer form having pressure sensitive adhesive positioned thereon

An assembly, comprising:

• a sheet having a pressure sensitive adhesive positioned thereon;
• and
• a folder-sealer apparatus including
• a first roller;
• a second roller which is positioned in operative contact with said first roller during advancement of said sheet between said first roller and said second roller;
• a third roller having (i) a roller surface, and (ii) a sealing protrusion extending from said roller surface;
• and
• a sheet stop positioned to halt forward movement of said sheet during advancement of said sheet between said first roller and said second roller and subsequently create a buckle in said sheet which is advanced into a roller nip defined by said first roller and said third roller,
• wherein (i) said sealing protrusion of said third roller is positioned in operative contact with said first roller during advancement of said sheet between said first roller and said third roller, and (ii) said sealing protrusion extends from said roller surface of said third roller at a location such that advancement of said sheet between said first roller and said third roller causes said sealing protrusion to operatively contact said pressure sensitive adhesive.
