Abstract
In a coil of material wound in a series of figure-8 coils with the crossovers progressing around the package but being interrupted at one point to provide a radial opening into the axial opening of the coil, in order to produce a thick-walled coil the material is first wound in a normal way with varying gains in order to produce a set of dense inner layers, while the outer layers are wound without variation in the gain to produce a honeycomb structure. The honeycomb section is of greater width (axially of the package) than the inner layers. A plurality of pins slidably mounted on a strip are pushed into the outside of the package through the openings in the honeycomb, whereafter the outer layers are compressed axially while retaining the pins within the outer layers. The pins permit payoff of the outer layers without danger of their collapsing and thereby forming kinks or twists within the package.
