Hollow Spindle Fancy Yarn Production
topic
Hollow spindle machines feed a core yarn through the centre of a rotating hollow spindle that unwinds binder or effect yarn from a package mounted on the spindle, wrapping the effect yarn around the core at a rate determined by the spindle rotation speed and core delivery speed ratio, enabling production of diverse wrapped, spiral, and gimp yarn structures without the core yarn twisting that would occur in conventional assembly winding.
Role
Provides the mechanically simplest approach to effect yarn production with maximum flexibility for producing diverse wrapped yarn structures through adjustment of feed ratio, spindle speed, and effect yarn selection, enabling small-batch fancy yarn production for fashion markets where frequent style changes require rapid machine reconfiguration between different wrapped yarn constructions.
