Method and apparatus for forming a continuous assembly of articles in overlapping and interconnected form

Abstract

Abstract APPARATUS FOR FORMING A CONTINUOUS ASSEMBLY OF GENERALLY FLAT-TYPE ARTICLES, SUCH AS ENVELOPES, IN OVERLAPPING, INTERCONNECTED FORM, WHICH ASSEMBLY IS PARTICULARLY SUITED FOR PROCESSING THROUGH HIGH SPEED PRINTING APPARATUSES. THE ARTICLES ARE FED ALONG A PATHWAY UNTIL EACH ARTICLE HAS ITS LEADING PORTION IN OVERLAPPING RELATION WITH RESPECT TO THE TRAILING PORTION OF A PRECEDING ARTICLE, USING ADHESIVE MEANS TO SECURE SAID ARTICLE TO THE PRECEDING ARTICLE ONLY ALONG MARGINAL PORTION THEREOF, AND PACKAGING THE ASSEMBLY. MARGINAL PORTIONS OF THE ARTICLES ARE PERFORATED AND THE RELATIVE CONSTANT SPEEDS OF TRAVEL OF THE ARTICLES PRIOR AND SUBSEQUENT TO ASSEMBLY THEREOF ARE CONTROLLED IN SUCH MANNER TO CAUSE AN ARTICLE TO OVERLAP, BY A PREDETERMINED AMOUNT, THE ADJACENT ARTICLE DOWNSTREAM OF SAME. SINCE ONE OF THE PRINCIPAL PURPOSES OF THE MARGINAL PORTIONS IS TO PROPERLY SPACE THE ARTICLES OF THE WEB WHILE BEING FED THROUGH THE PRINTING APPARATUS, AND WHICH ARE THENCE REMOVED TO SEPARATE SAME, THE ADHESIVE MEANS IS APPLIED ONLY TO AREAS OF THE MARGINAL PORTIONS SO THAT THE ARTICLES ARE NOT ADHESIVELY SECURED TOGETHER ALONG TRANSVERSE AREAS BETWEEN THE MARGINAL PORTIONS.
