1. The method of producing a curled ribbon from a continuous supply of non-curled ribbon to ensure a continuous uninterrupted production of the curled ribbon comprising the steps ofi) providing a continuous supply of non-curled ribbon;
- ii) providing a curling device;
iii) providing drawing apparatus downstream of the supply relative to the continuous operation of obtaining curled ribbon;
iv) drawing the curled ribbon from the supply of non-curled ribbon so as to be in contact with the curling device so that the non-curled ribbon is imparted with a curl by virtue of being in engagement with the curling device; and
v) separating the curled ribbon from the drawing apparatus subsequent to being drawn from the curling device to travel in a predetermined path so as to prevent entanglement of the curled ribbon with the drawing apparatus whereby the curled ribbon is mass produced.

4. The method of producing multiple strands of curled ribbon from a continuous supply of multiple strands of non-curled ribbon to ensure a continuous uninterrupted production of the curled ribbon comprising the steps of
i) providing a continuous supply of multiple strands of non-curled ribbon; -
ii) providing a curling device;
iii) providing drawing apparatus downstream of the supply relative to the continuous operation of obtaining multiple strands of curled ribbon;
iv) drawing each of the curled ribbon of the multiple strands from the supply of the multiple strands of non-curled ribbon so that each of the strands from the multiple strands of the non-curled ribbon is placed in contact with the curling device so that each strand of the non-curled ribbon is imparted with a curl by virtue of being in engagement with the curling device; and
v) separating each strand of the multiple curled ribbon from the drawing apparatus subsequent to being drawn from the curling device to define a given flow path so as to prevent entanglement of any of the curled ribbon with the drawing apparatus whereby the strands of curled ribbon are mass produced. - View Dependent Claims (5, 6, 7, 8)
