Abstract
A reel for use with a web material such as a magnetic recording tape, a photographic film, etc, wherein the reel is so designed as to enable the web to be removed from the reel without first unspooling the web from the reel. The reel comprises a first and a second flange assembly, each having a flange member and a core element affixed to the flange member. Means are provided for temporarily attaching the core element of the first flange assembly to the flange member of the second flange assembly, and also for attaching the core element of the second flange assembly to the flange member of the first flange assembly. By detaching the temporary attaching means, the flange assemblies may be separated, thereby allowing a web wrapped on the reel to be removed without unspooling. The flange assemblies may be reassembled for repeated use.
