ABSTRACT:
Apparatus for producing filling material includes guide structure wherein a tow of filling and binding fiber is continuously guided through a heating zone in which the binding fiber becomes fused to the filling fiber at least at the surface of the tow, the tow is then continuously guided through a cooling zone in which at least a surface-consolidated tow is formed, and the consolidated tow is then continuously guided into a heated cutting means and cut and fused into tufts.
