Abstract
Method and apparatus are provided for forming an envelope wherein front and rear panels of an envelope are incorporated in continuous or discrete webs or sheets. Heat activatable adhesive is applied to three peripheral edge portions of one of the envelope panels in facing engagement with the other of the panels. The webs or sheets are fixed together and fed into a printing machine such as a table or desk top laser printer wherein the heat fusing rolls of the printer are utilized to activate the heat activatable adhesive to thereby secure the envelope panels together to form an envelope pocket. One of the envelope panels incorporates a sealing flap portion which may be provided with a rewettable adhesive pattern, while the facing portion of the opposed sheet may be provided with an antistick composition to prevent premature sticking between the sheets in the area of the sealing flap.
