Abstract:
A method for simultaneous formation and attachment of a loop to an apertured device, in which the loop is formed from a loosely structured fibre bundle of twisted yarn, and the device has first and second apertures through which the loop can be taken, in which the method comprises:withdrawing a leading end of yarn from a yarn supply and feeding the leading end through the first aperture in one direction, and through the second aperture in an opposite direction; taking the leading end of yarn away from the device and along a guide path so as to form a basic loop; withdrawing further yarn from the supply simultaneously with applying movement of the basic loop along the guide path so as to apply successive loop turns to the basic loop and therefore form a progressively increasing loop core; and applying relative twist between the loop core and each successive loop turn so as to form a cohesive looped fibre bundle attached to the device.
