Abstract
Abstract A device for breaking open a frangible cartridge which is adapted to contain a web, the cartridge being of the kind provided with spaced web supply and take-up chambers and with an interconnecting web guide channel. The device includes a fixture for engaging the web take-up chamber of such a cartridge in a manner preventing movement of the web take-up chamber in at least one direction and a guide surface which serves to direct the web take-up chamber into engaged relation with the fixture. An offset portion of the guide surface retains the web take-up chamber at the fixture. The device further includes a breaker lever which is mounted for movement relative to the fixture for moving, generally in the one direction, the web supply chamber and web guide channel of a cartridge whose web take-up chamber is engaged by the fixture. Accordingly, the cartridge can be broken open for extraction of a web from the web take-up chamber.
