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.

Coil of flexible material with inserts in outer wall

The invention relates to a package of material wound in a series of figure-8s with the cross-overs advancing around the package, and the cross-overs being omitted at at least one point on the circumference of the package to leave a radial hole into the center of the package for inner end feedout to allow payout without twist. This hole is ordinarily somewhat diamond shaped, with its major axis extending substantially perpendicular to the axis about which the material was wound. A payout tube is placed in that hole, this payout tube having an oval shape.

Package of flexible material with oval payout tube

In a package formed of a plurality of layers each composed of a number of figure 8 winds with the cross-overs progressing around the package and with a radial opening extending from the periphery of the package to the axial opening through which radial opening the inner end of the material is led out, a funnel is provided with a stem positioned in the radial opening and with its mouth substantially at the mid-plane of the package. The funnel has a width in the axial direction of the package at least substantially as great as the axial length of the package. The funnel may be mounted in such a way that it can wobble slightly. The funnel guides the loops falling off of the inside wall of the package so as to prevent birdsnesting and provide for continuous and rapid payout.
