Abstract: Filaments are fed into a jet where an air blast blows them down through a tube into a bottom container with smooth hemispherical interior surface. Here the filaments move in a rotating path forming spherical cocoons with concentration of filaments in their outer surfaces. The air escapes through outlets in the container wall. The filaments are subsequently bonded together at their points of contact, either by spraying them first with suitable adhesive or by incorporating a fusible component and finally heating the rounded cocoons. Alternatively, thermoplastic filaments are used and the cocoons are heated. These cocoons form bulky resilient fillers with good thermsl insulation.
