Abstract
A drawing apparatus for air spinning machines with multiple feeds includes independent introducer elements that feed simultaneously at least two separate slivers of textile fiber. A first drive roller intercepts a first sliver and a second drive roller intercepts the second sliver. The drive rollers may be operated at different speeds of rotation, to perform different degrees of drawing of the two slivers.
