Abstract
Description
- This invention relates to a core for receiving sheet material.
- Cores for receiving sheet material are well known. The sheet material may be, for example, paper used in the printing industry, or plastics film or cardboard used in the packaging industry. The sheet material is wound on the core to form a reel. The reels are usually bulky and heavy, requiring handling by machines.
- The cores may be made of cardboard or a metal such for example as aluminium. Even with metal cores such for example as aluminium, it is difficult to produce the cores with sufficient strength and rigidity when the cores are of a substantial diameter, for example more than 200 mm (8 inches). During use of the reels on machines such for example as printing machines, it is essential that the cores maintain their shape and accuracy. The cores usually comprise a tube, a first end member which extends into a first end of the tube, and a second end member which extends into a second end of the tube. The tube can be made to be made more rigid by increasing the tube wall thickness. However, increasing the wall thickness of a metal tube such for example as aluminium increases the weight of the tube and desirably the weight of the tube should be kept to as minimum. Also, the internal dimensions of the tube should be such that chucks of handling machines are able to enter into the core via the first and the second end members. The handling tends to require that wall thicknesses are between 15-17 mm. The first and the second end members are usually made of a plastics material and these become increasingly difficult to mould with increasing tube diameters. The plastics material tends to shrink unevenly after moulding, and then it does not maintain the required shape for the end members.
- It is an aim of the present invention to reduce the above mentioned problems.
- Accordingly, in one non-limiting embodiment of the present invention there is provided a core for receiving sheet material, which core comprises a tube, a first end member which extends into a first end of the tube, and a second end member which extends into a second end of the tube, and the core being such that the tube is formed of a plurality of part circular tube portions which are connected together along longitudinally extending edges, and the first and the second end members are each formed of a plurality of part circular end member portions which are connected together along longitudinally extending edges.
- With the tube being made of the part circular tube portions, and the first and the second end members being made of the part circular end member portions, it is possible to make cores having diameters greater than 200 mm, whilst maintaining high tolerance requirements and high core stiffness requirements. Whilst the core of the present invention is such that its diameter is preferably larger than 200 mm, the core may have a smaller diameter if desired.
- In a first embodiment of the invention, the core may be one in which the longitudinally extending edges on the part circular tube portions have engaging formations for engaging adjacent longitudinally extending edges, and in which the engaging formations on the part circular tube portions extend inwardly of the tube.
- The engaging formations on the longitudinally extending edges of the part circular tube portions may be connected together by any suitable and appropriate means including, for example, welding, screw fasteners, rivets or dips.
- Advantageously, the strengthening formations on the part circular tube portions form strengthening splines which extend from an inner surface of the tube.
- The core may be one in which the part circular tube portions each has a longitudinally extending groove comprising a base wall, a pair of side walls and a top wall, and in which the longitudinal extending grooves at the first and the second ends of the tube are for receiving the first and the second end members respectively. Preferably there is only one of the grooves in each of the part circular tube portions. However, if desired, there may be more of the grooves, for example two or three of the grooves in each of the part circular tube portions.
- Usually, the longitudinally extending grooves will not extend the full length of the tube. Usually, the longitudinally extending grooves will only extend longitudinally inwardly from the first and the second ends of the tube for a distance slightly longer than the length of the first and the second end members that are in the tube.
- In the first embodiment of the invention, the longitudinally extending edges of the part circular end member portions may be dove tail joint formations whereby the part circular end member portions are connected together by dove tail joints. Other connecting means may be employed for connecting the longitudinally extending edges of the part circular end member portions.
- In a second embodiment of the present invention, the core may be one in which the longitudinal edges on the part circular tube portions are welded together, and in which the part circular tube portions are each provided on their inner surface with a plurality of longitudinally extending strengthening formations.
- The longitudinally extending strengthening formations are preferably T-shaped in cross section. Other cross sectional shapes may be employed.
- Preferably, the tube has forty-eight of the longitudinally extending strengthening formations. More or less than forty-eight of the longitudinally extending strengthening formations may be employed.
- In the second embodiment of the invention, the first and the second end members may have finger formations which locate in or between the longitudinally extending strengthening formations on the part circular tube portions.
- Preferably, the tube is made of aluminum. Other metals may be employed. Depending upon the required diameter of the core, the tube may also be made of plastics materials.
- The first and the second end members are preferably made of a plastics material. Other materials may however be employed if desired. The first and the second end members are preferably constructed to be reusable but they may be constructed to be disposable if desired.
- The core may include a radio frequency identification tag. The use of the radio frequency identification tag enables the location of the core to be tracked from manufacture through to winding of the core to produce a reel, through to use of the reel, and return of the core for reuse purposes. The radio frequency identification tag may be formed as part of the first or the second end member.
