Definitions
- ABSTRACT This invention relates to devices for unwinding filamentary material from a bobbin or spool.
- the bobbin or spool has at least one cheek and a rotatable capping flange surrounds this cheek: a tube is located at the centre of the bobbin or spool and has a flared end, and means are provided for rotating the central tube and the capping flange together.
- the filamentary material may be taken off the bobbin or spool, be passed over the flared end of the central tube and along the latter and out of its other end.
- the present invention relates to a device for unwinding a filamentary material from a bobbin or spool in the opposite direction to that in which it was wound on.
- the invention consists in a device for unwinding filamentary material from a bobbin or spool in the reverse direction to that in which it was wound on, comprising a rotatable capping flange surrounding one cheek of the bobbin or spool from which the material is to be unwound, a tube located at the centre of the bobbin or spool and having a flared end, and means for rotating the central tube and the capping flange together, the arrangement being such that the filamentary material may come off the bobbin, pass over the flared end of the central tube and along the latter and out of its other end.
- the unwinding device shown therein comprises a bobbin or spool of wire mounted on a fixed hub 2, in which is mounted a hollow shaft 4, which is free to rotate in ball bearings 3, 3a, and one end of which is integral with a pulley S which is coupled to a drive means (not shown) by a transmission belt 6.
- a central tube 7 slides within the hollow shaft, the other end of said tube being flared at 8, and this tube 7 is subjected to the action of a spring 9 which is held against the bottom 11 of a counter-bore in the shaft 4 and against a stop fixed to the tube 7.
- an anti-billowing cylinder 14 which encloses the assembly in such a way as to prevent the filamentary material coming from one bobbin interfering with that of the next bobbin or spool.
- the flexible fingers 15 are fixed to cylinder 14 and are in contact by their free ends with the periphery of flange 12 so that thread F is maintained in contact by said fingers with the periphery of the flange.
- the spring 9 serves as a cushion to absorb the momentary high tension resultant from temporary catching or jamming of the thread being fed from the spool 1. If it were not for the aforementioned cushioning effect, the thread might be broken.
- the increased tension in the thread will move the innermost edge of the flaired end portion 8 inwardly into contact with the outer surface of the flange 12 to provide additional frictional driving force between the tube 7 and the flange 12 to create a more effective rotation of the flaired end, the thread and the flange to aid in disengagement of the jam.
- the additional rotative force is in addition to the normal frictional drive provided between shaft 4 and tube 7 by frictional engagement of element 101 with shaft 4.
- the unwinding is executed from a fixed spool to the consequent advantage of avoiding the inertia of a rotating spool as is the case in many presently known unwinding devices.
- the present invention provide improved functional results, it is also much more economical to construct and use due to its more simple nature.
- the device can be used in any industry in which it is necessary to remove thread, wire, string or the like from a spool.
- the device would find many uses in the textile industry, the wire-drawing industry in which wire for cables is removed for spools for twisting and drawing into cables and in numerous other industries requiring similar wire or thread unreeling operations.
- a device for unwinding filamentary material from a fixed non-rotating bobbin or spool in the reverse direction to that in which it was wound on, said bobbin or spool having at least one cheek said device comprising a fixed hub supporting said bobbin or spool, a hollow shaft mounted for rotation in said hub, a rotatable capping flange surrounding the periphery of said cheek, a central tube located at the central axis of said bobbin or spool and mounted for axial movement in said hollow shaft, resilient means biassing said central tube outwardly of said hollow shaft, said central tube having a flared end, and means for rotating said central tube and said capping flange together, the arrangement being such that the filamentary material is wound off said bobbin or spool and passes over said flared end of said central tube into said central tube and along the interior of said central tube and out the other end of said central tube.
- the invention of claim 3 additionally including flexible fingers mounted on the anti-billowing cylinder and having ends engaging the periphery of said capping flange.
