A tabbed film strip comprising a film portion and a tab portion secured together in parallel adjacent edge relation by a connecting tape overlapping the film and tab portion and adhesively secured thereto in an arrangement leaving a major area of the film portion and tab portion uncovered throughout their lengths. Apparatus to form this product and to carry out a process of making it comprises a housing which supports individual feed supplies for the film portion and the tab portion and which also supports a feed supply for the connecting tape. The tape has pressure sensitive adhesive on one of its surfaces for securement to the film and tab portions. Forming mechanism is supported on the housing and has guide grooves therein as well as guide rollers and a hold-down arm associated therewith arranged to place the film portion and tab portion in parallel adjacent edge relation and to secure these two portions together by means of the tape. The film portion and tab portion, after leaving the forming mechanism, pass over a power driven drum which pulls the film and tab portions, as well as the tape, through the forming mechanism for the formation of the tabbed film strip. This drum is arranged to feed the completed film product to other mechanism upon demand of the latter.
