Abstract:
A supply spool and flyer assembly for an apparatus adapted to helically assemble a pair of filaments about a central axis as said filaments are passed through a gathering point, said supply spool and flyer assembly comprising first supply spooling means having a first filament wound thereon, flyer means disposed between said first supply spooling means and the gathering point, said flyer means being mounted on axle means for rotation therewith about said central axis, said flyer means being provided with first guide means for guiding said first filament along said flyer means, wherein said first guide means and said first supply spooling means are configured to cause said first filament to pass by said central axis and then onto said flyer means where said first filament is deviated off-axis before being returned to said central axis at the gathering point, and second supply spooling means disposed within an envelope defined by a rotational movement of said flyer means about said central axis, said second supply spooling means having a second filament wound thereon, said axle means being provided, downstream of said second supply spooling means relative to a filament supply direction of said second filament, with second guide means configured to cause said second filament to rotate with said axle means about said central axis as said second filament is moved through said second guide means, wherein said second guide means and said second supply spooling means are configured to cause said second filament to pass by said central axis and then to said second guide means where said second filament is deviated off-axis before being returned to said central axis at the gathering point.
