2123313 9310971 PCTABS00022 Free-flowing dunnage of molded pulp pieces having random, non-nestable shapes to insure the free-flowing characteristic, is made by a method and apparatus involving passing slurry from pulper (32) to multi-cavity molds (16) placed around a rotating molder structure (34) at the lower loading position, rotating said structure (34) to the drying position (46) and the partially dried pieces are removed at the removal position (48), and thereafter drying them free of form support to obtain random shapes.
