Abstract
A densely packed storage drum containing wire, and a method and apparatus for producing the same. The storage drum having an interior storage cavity into which wire is fed. The drum is supported on a turn table adapted to rotate and index the storage drum relative to a rotatable laying head which guides the wire into the drum. A capstan turning at a set rotational velocity pulls the wire and delivers the wire into the rotating laying head. As the laying head feeds the wire into the storage drum the difference in the rotational velocities of the capstan and laying head causes the formation of loops of wire in the storage drum. By varying the relative velocities of the capstan and the laying head, and rotating and indexing the storage drum relative to the laying head the wire can be deposited into the drum in layers, with each layer having a plurality of loops of a specified diameter circumferentially and eccentrically positioned about the interior cavity of the drum. Adjacent layers having different loop diameters and circumferential positions, producing a densely packed storage drum filled with wire having a uniform radial density.
