Title: Process of preparing a film strip for handling
Claims: Having thus described our invention, we claim: 1. The process of preparing a film strip for handling comprising simultaneously supplying a strip of film and a tab strip of approximately the same thickness from roll sources in longitudinal parallel edge relation on a longitudinal surface between longitudinal side rails and with adjacent edges of said strips disposed on opposite sides of a dividing projection which is of less length than the longitudinal surface and which is spaced from one of the side rails on the side that is to receive the tab strip a lesser distance than the width of the tab strip to cause the latter to buckle laterally when received therein, whereby as said strip portions pass beyond said dividing projection the buckled tab strip straightens out and expands laterally so as to be in adjacent edge relation and in the same plane as the film strip as aforesaid, then supplying from a rolled source a connecting strip having a pressure sensitive surface on one side thereof in overlapping relation on said strips along said adjacent edges, and then pulling the three strips partly around a roller to compress the connecting strip onto said tab and film strips and to secure the pressure sensitive adhesive to the two strips. 2. The process of claim 1 including the further step of pressure rolling said connecting strip onto said other two strips. Other info: Inventors: Petry, Jr., Chester H. (Newberg, OR, US) Hensley, J.
