ABSTRACT:
A thread-delivery device is disclosed including a storge body formed by bars disposed in the shape of a polygon. The bars form two axially-spaced sections of approximately equal circumferential length. A cylindrical member having sawtooth-shaped threading grooves is rotated between the bars of the first section. The bottom of the threading grooves is located radially inwardly of lines interconnecting the bars. A ring having a conical face is disposed at the thread entrance opening adjacent to one end of the first section and a sensing device is provided to sense the endmost thread wound on the second section.
