ABSTRACT:
A batch process and apparatus are provided for molding fiberballs, comprising load-bearing fibers and binder fibers, into shaped articles, preferably using hot air within a perforated mold to allow circulation of the air through the fiberballs. The techniques are particularly adapted to molding cushions of varying shapes and sizes, without excessive wastage of material, using relatively simple flexible equipment.
