Abstract
A spool comprises a three-dimensional substrate and a core. The three-dimensional substrate comprises a plurality of projections extending outwardly from a plane of the substrate. The spool comprises a first plurality of spirally wound portions and a first plurality of helically wound portions. The substrate is spirally wound around the core to form each spirally wound portion of the first plurality of spirally wound portions. The spirally wound portions of the first plurality of spirally wound portions are located next to each other along a longitudinal axis of the core between a first transversal side edge of the core and a second transversal side edge of the core. The substrate is helically wound around the core along the longitudinal axis of the core to form each helically wound portion. Each helically wound portion extends between two adjacent spirally wound portions of the first plurality of spirally wound portions.
