' It has been customary in such mannfac-, ture to make a wideba'nd,comprising sup port of 'pyroxylin or the, like coated with' photographic emulsion, =then to slitfthis hand into narrow strips jofithe desired width, then to perforate these strips,':ifdesired, and't'ake a la1-ge' roll 0f tl1e desired width to the cartridge assembling station; Where each 1nclividual length was cutoff as needed, either adhesive; When the" a'dhesiv p ygassembledship isw ouridfup.

[This has certain advanta es ar tioularly in reducing breakage in passing around a sharp bend or sprocket. In such long strips as'here are contemplated, the

normal shrinkage, off the material renders it impossible to calculate exactly here the splice will lie With'respe'ct to, sprocket holes and, if the edge gar the material coincides with theregistering edges otuop'posite perforations, ,it makes a place i peculiarly susceptible to bends. and breaks; The oh- 7 lique splice is so inclined as toinsure its not passing through tvvo perforations," the edge of the material cannot coincide with the edge of appertoration and the spliceipasse's 'a bendingpointgradually instead of abruptly.
