<p>For attaining high speed production of envelope assemblies, with substantial savings of costly time and labor, the present invention teaches a method or plan of manufacture which involves the use of high speed collating machinery such as is customarily employed in the production of continuous record forms, business forms, and the like, from continuous paper webs passed through the collating machinery uninterruptedly at a rapid rate of speed. The envelope assemblies so produced leave the collating machinery as complete units ready for use.</p> |
