Abstract
Abstract A cartridge for a web comprises a casing having a first casing part for enclosing part of a web storage space. This first casing part has an access opening for the web storage space. The remainder of the web storage space is enclosed by a second casing part and by a door for the mentioned access opening. The second casing part is complementary to the first casing part whereby the first and second casing parts jointly enclose the web storage space. The first and second casing parts are mounted for movement relative to each other between two positions. The mentioned door is coupled to the second casing part for selectively closing the access opening upon relative movement of the first and second casing parts to one of the mentioned positions and for alternatively opening the access opening upon relative movement of the first and second casing parts to the other of the mentioned positions. A device is located in the web storage space for receiving a web in a wound condition. A cartridge for a web comprises a casing enclosing a web storage space, a rotatable device in the web storage space for receiving a web in a wound condition, a brake member movably mounted in the web storage space, a device for biasing the brake member into braking relationship with the mentioned rotatable device, and a device for selectively releasing the brake member from the rotatable device.
