Abstract

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.

Description

TWO PIECE REEL This invention relates to film reels especially film reels made of plastics material. Such reels have to be sufficiently rigid not to warp as this can obstruct the insertion of the film and the winding of the film onto the reel. To facilitate winding of the film onto the reel it is desirable that the periphery of the reel sides, which are usually in circular plate form, are dished inwardly so that the distance between the reel sides at their peripheries is greater than that at the reel centre or hub.
Some known reels of this kind are formed in a plurality of pieces including the side plates and a central core having an outer rim into which the film end is engaged and round which the film is wound to fill the reel, and a central hub shaped for mounting onto a reel spindle of a film winding apparatus.
An object of the invention is to provide a film reel which is of simpler construction than known reels and more rigid in use.
In one broad form this invention provides a film reel formed by a pair of interengaging substantially circular side plates each having a central aperture engagable on a reel spindle, a number of upstanding angularly spaced arcuate hub forming flanges, a number of upstanding angularly spaced arcuate rim-forming flanges radially spaced from the hub forming flanges, and a key means, the two side plates being assembled such that the hub-forming flanges of one side plate are disposed
OMPI between the hub-forming flanges of the other side plate to form the reel hub, and the rim-forming flanges of one side plate are disposed between the rim-forming flanges of the other to form the reel rim, and the key means of the two side plates are intergaged, and the assembly being bonded together.
Preferably the key means comprises an upstanding lip along the top free edge of each of the rim forming flanges of the side plates which are engageable in corresponding grooves extending between the rim forming flanges. Alternative or complementary key means may be formed by similar upstanding lips on the hub forming flanges which are engageable in grooves between the hub forming flanges.
The dimensions of the upstanding lips of the two plates are preferably such that when the two plates are assembled prior to bonding the lips are a ram fit in the grooves and engage firmly. The rim forming flanges on one or both plates may be of greater height than the hub forming flanges whereby when the plates are assembled their centres may be urged together so that the plates are dished.
The two plates are preferably identical but the flanges of the two plates may be different in their angular spacing provided the flanges of the two plates on assembly form a substantially continuous rim and a substantially continuous hub.
The assembled side plates are bonded together by conventional solvent welding, sonic welding, or by adhesives to form a substantially rigid reel. One preferred embodiment of the invention will now be described with reference to the accompanying drawings in which:
Fig. 1 is a perspective view of one reel side plate; Pig. 2 is a section on the line II-II of Fig. 1 looking in the direction of the arrows;
Fig. 3 is an enlarged section of Fig. 2 showing the rim flanges interengaged on assembly;
Fig. 4 is a section of an assembled reel on the line IV-IV of Fig. 1; and Fig. 5 is a -section of an assembled reel on the line V-V of Fig. 1.
In the drawings the same references are used to designate the same parts. The illustrated example of the invention shows the two reels as identical bu.t as will be explained herein variations may be made.
Referring to the drawings Fig. 1 shows one side plate of a reel. This comprises the plate 1 with the conventional apertures 2 giving the effect of spokes 3 bound by a peripheral marginal ring 4. In the centre is an insert 5 of rigid material such as a metal having a shaped aperture 6 for driving engagement on the reel spindle of a film winding apparatus.
OMFI Around the insert 5 are two arcuate hub forming flanges 7 each extending angularly through 90° and separated by spaces each extending through 90° into which the flanges 7 of the second plate mate on assembly of the two plates to form a substantially continuous reel hub.
Spaced radially from the flanges 7, are two arcuate rim forming flanges 8 which are taller than the flanges 7 for the purpose to be described. The flanges 8 extend angularly through 90° and are separated by spaces also extending angularly through 90°. The connection of the bases of the flanges 8 to the plates is reinforced by gussets 15. In each of the spaces between the flanges 8 is an arcuate groove 10 the inner wall of which is coplanar 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 the 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 the mating plate.
On assembly of the two plates to form the reel the flanges 7 and 8 of each plate mate into the spaces between the respective flanges of the other plate to form the hub and rim of the reel and the upstanding lips 12 engage the respective grooves 10. As mentioned above the lips 12 are a tight ram fit in the grooves 10 which
OMFI forces the inner surface 13 of the lip against the flange 9. The end radial members 11 of each plate also engage the respective slots 14 in the other plate.
As the flanges 7 are lower than the flanges 8 the centres of the two plates can be forced towards each other thus causing the plates to be dished which facilitates winding the film onto the reel.
The assembled reel is then bonded together by any suitable means such as glue or epoxy resin adhesives, but the preferred bond is by solvent welding, or by sonic welding both of which are well known in the art and need no further explanation here.
It is to be understood that the above described embodiment describes only one way of performing this invention and various modifications obvious to one skilled in the art may be made without departing from the scope of this invention. For example although in the embodiment described each plate has two each of the flanges 7, 8 and 9, more may be provided and in such case the spaces between them may be so dimensioned and shaped that in the assembled reel a substantially continuous hub is formed as well as a substantially continuous rim. These flanges may also extend over any suitable angle providing the flanges of the two side plates interengage on assembly of the reel to form a rim sufficient to support substantially undistorted a film wound thereon.
Ol.lPI The plates may also be of any rigid material such as metal e.g. aluminium although preferably they are of plastics material, a suitable plastics material being high impact styrene.
