Abstract
421,877. Photographic and kinematographic films. HALLO, J. H., 2, Mozartstraat, Antwerp, and GEVAERT PHOTOPRODUCTEN NAAMLOOZE VENNOOTSCHAP, Oude God, both in Belgium. April 3, 1934, No. 10054. [Class 98 (i)] A light-sensitive film which may require to be cut as to a narrower width or to a shorter length is provided on one or both faces with one or more incisions, extending partly through its thickness, along the line or lines where severance may be necessary, so that division will be possible by bending only, without the use of tools. The incisions are not so deep as to weaken the film in ordinary usage, and preferably do not extend up to the edges or ends of the film in order to avoid accidental rupture.
