COIL ASSEMBLY HAVING PERMEABLE HUB

摘要

A coil assembly comprising a coil of a strand-based material retained in a figure-8 configuration, and having an inner layer and an outer layer, where the inner layer of the coil defines a core region of the coil, and where the coil is configured to unwind loop by loop beginning from the inner layer and moving towards the outer layer as the strand-based material is drawn through a payout hole. The coil assembly also comprises a permeable hub configured to reduce payout entanglement of the strand-based material.

1. A coil assembly comprising:
a coil of a strand-based material retained in a figure-8 configuration, and having a payout hole for dispensing successive segments of the strand-based material, the payout hole extending from an inner layer of the coil to an outer layer of the coil, wherein the inner layer of the coil defines a core region of the coil, and wherein the coil is configured to unwind loop by loop beginning from the inner layer and moving towards the outer layer as the strand-based material is drawn through the payout hole; and a permeable hub retained in the core region of the coil, the permeable hub being displaceable by the unwinding of the strand-based material, and configured to prevent the strand-based material from forming more than one loop at a time in the core region as the strand-based material is pulled through the payout hole.
