Photographische Filmkassette und Verfahren zur deren Montage

A method for assembling a photographic film cassette (10,60) is described, reducing ineffective processes in the darkroom. The photographic film cassette used for that method has a cassette shell (11,61), consisting of two plastic shell halves (11a,11b,61a,61b) and a rotatable spool (15) with a photographic film (13) wound thereon, said spool (15) having a cylindrical core (16) axially extending between a pair of flanges(18), wherein a leading end of said photographic film (13) is advanced out of said cassette shell (11,61) through a film passage mouth (14) formed in said cassette shell (11,61) by rotation of said spool (15). The method comprises the steps of mounting a film connecting sheet (17) on said core (16), said film connection sheet (17) having a width approximately equal to that of said photographic filmstrip (13), joining said plastic shell halves (11a,11b,61a,61b) to one another to form said shell (11,61) after having inserted said spool (15) therebetween with a free end (17c) of said film connecting sheet (17) projecting from said film passage mouth (14) to the outside of said cassette shell (11,61); connecting a trailing end (13a) of said photographic film (13) to said free end (17c) of said film connecting sheet (17); and winding said film connecting sheet (17) together with said photographic film (13) completely in said cassette shell (11,61) and onto said core (16) by rotating said spool (15), with said film connecting sheet (17) extending from one of said pair of flanges (18) to the other of said pair of flanges (18).
