Abstract

309,991. I. G. Farbenindustrie Akt.- Ges. April 19, 1928, [Convention date]. Roll spools; film packs.-In fixing paper strips or tabs to roll or pack films, the edge of the paper attached to the emulsion layer is a non-straight line. By this means the union. between the film and paper is given a greater resistance to bending and liability of the emulsion layer to crack along the paper edge when winding the film is diminished.
