A web cassette has a carrier plate with a supply and take up cartridges mounted thereon. The web is pulled from a reel in the supply cartridge, led over a path including guide posts or rollers, and connected to a reel in the take-up cartridge. A V-tooth coupler on each of these reels interfaces with driven V-tooth couplers on a machine using the cassette to transport the web from the supply to the take-up cartridge. When the transport is completed, the take-up cartridge is removed for processing, the former supply cartridge is moved to the take-up position on the cassette, and a new supply cartridge is mounted on the cassette.
