for example may be employed to provide a locating mechanism instead in use the low melting point filament 32 which is drawn off the first spool 20 passes through the aperture 30 and the centre of the second spool 22 and therefore in the illustrated example the centre of the second spindle 28 which has a bore running through its centre and is fed to a stitching tool of the machine such as a needle or other stitching tool such as a hook a bobbin a looper and a spreader for example as the case may be of the sewing machine 14 via a thread guide mechanism which in the present example includes two guide wheels 40 42 though may involve a considerably more sophisticated guide mechanism as appropriate the second spool 22 is mounted on the capsule 26 u2014 here using the second spindle 28 u2014 once again preferably in a manner which resists or more preferably prevents relative rotation of the second spool 22 and retaining mechanism provided by the second spindle 28 the second spool 22 carries a second filament 34 which in this example is provided by a conventional textile filament typically though not necessarily polyester of the kind ordinarily used as sewing thread the textile filament 34 is similarly fed to the sewing machine 14 via the guides 40 and 42 in operation the action of the textile filament 34 as it is drawn off the second spool 22 will be such that it automatically winds itself around the first filament 32 subsequent to the passage of the low melting point filament through the centre of the second spool 22 the result is the automatic inter winding of the two filaments 32 34 to create a composite sewing thread 12 for use.
