Abstract
Apparatus for the manufacture of fabric, especially tire building fabric ply material, in which a pair of rotatable parallel spindles are each surrounded by a helical member rotatable in the opposite direction to the respective spindles. The opposite rotation of the spindles and the helical members helps to ensure a uniform winding as fabric is built up from filamentary material applied around the spindles from a feeding head rotating around the spindles.
