Process for the manufacture of film cartridges

摘要

In a process for the manufacture of film cartridges which have a substantially cyclindrical wall, a film opening extending along a generating line of the cylinder and caps at the ends, one plate per cartridge is separated from a flat strip of material to form the cartridge wall, which strip of material contains the plates for several cartridges and has a width corresponding to the circumference of a cartridge wall, and the said strip of material is fitted continuously with a sealing material along at least one of the edges for the film opening before the plates are separated, the said sealing material being delivered to the strip of material in the form of endless band of sealing strips which are bonded to the strip of material as they pass through a glueing station.
