Abstract
The present invention concerns a novel method of winding bobbins having a predetermined radial fluid permeability which comprises winding yarn or fabric on a hollow permeable core, passing a fluid radially through the windings on the core and terminating the winding when a predetermined fluid pressure is attained, and an apparatus therefor. Said method and apparatus enable 'bobbins' to be uniformly dyed.
