<p>A film reel formed by a pair of interengaging side plates. Each side plate (1) having a central aperture (6) engageable on a reel spindle, two arcuate hub forming flanges (7), two arcuate rim forming flanges (8), and key means comprising a groove (10) the inner wall of which is co-planar with the outer wall of an adjacent upstanding intermediate flange (9). Along the top free edge of the flanges (8) is an upstanding lip (12) disposed and shaped to be a tight ram fit in the groove (10) of a second similiar mating plate. Each flange (8) also has end radial members (11) adapted to engage in a slot (14) between the contiguous ends of the flanges (8) and (9) of said second similar mating plate. On assembly of the two plates to form the reel, the flanges (7) and (8) of each plate mate into the spacer between the respective flanges of the other plate to form the hub and rim of the reel and the lip (12) engages the respective grooves (10). The end radial members (11) of each plate also engage the respective slots (14) of the other plate. The assembled plates forming the reel are then bonded together by any suitable means. </p> |
