ABSTRACT:
The present invention relates to a method and apparatus for producing communication articles such as postcards, envelopes or the like in each of which display surfaces for information or the like are separably bonded with a synthetic resin therebetween by heating for concealing information such as correspondence or a printed display medium and then mailing it. It is an object of the invention to enable easy and smooth separating of a film-containing sheet and accurate insertion of a film in a sheet.
In order to achieve the object, a continuous sheet having a plurality of communication article-forming sheets which are connected in series is folded in at least two, a continuous film is inserted between the sheet portions into which the continuous sheet is folded to form a film-containing continuous sheet which is then heated and pressed to that the sheet portions of the continuous sheet are bonded with the film therebetween, and the film-containing continuous sheet is then separated into the respective communication article-forming sheets by hitting the positions between the respective communication article-forming sheets of the continuous sheet while pulling the film-containing continuous sheet to produce communication articles.
