ABSTRACT:
The invention relates to a support device conventionally used in conjunction with binder systems to support binder strap securing means for securing binder straps in such binder systems, to thereby secure a number of sheets of material together. The support device comprises an elongate member having an elongate channel section body portion and a clamping flange extending from the body portion along the length thereof, whereby an edge portion of a cover sheet or the like can be located and secured between the body portion and the clamping flange. The invention therefore also extends to a binder system including such a support device and to a cover sheet having such a support device secured thereto. By providing two such support devices a number of sheets of material can be bound between two cover sheets secured to the devices.
