Abstract: 1416070 Web-containing cartridge assembly INTERNATIONAL BUSINESS MACHINES CORP 23 Nov 1973 [27 Dec 1972] 816/75 Divided out of 1416069 Heading B8M A web-containing cartridge assembly includes a reel 28 with a hollow hub 44 and single flange 46 with a releasable open-ended cover 26 disposed over the reel to enclose a web 54 wound on the reel, the cover 26 being releasable from the reel only by a separate release tool 74 whereby to guard against inadvertent release. The reel has releasable fingers 52 with cam follower surfaces 62 to be engaged by the release tool 74 which comprises an annular cam surface 76. The surfaces 62 preferably lie on a surface of revolution about the hub axis and are preferably also curved in a plane through the hub axis; the cam surface 76 on the release tool is preferably similarly formed. In a further embodiment, the tool 74 includes resilient fingers which extend into the hub to engage a surface irregularity on the internal surface of the reel to releasably grip the reel. The hub and cover construction forms the subject of Specification 1,416,069, and is used in the same way as in that application. (For Figures see next column.)
