ABSTRACT:
In apparatus for making a pile article by applying a backing to free ends of an assembly of pile fibers, the combination of means for forming pile units each comprising a laterally compressed and substantially radially symmetrical array of pile fibers, means for supporting assembled pile fibers, means for distributing a plurality of the pile units transversely across the supporting means and releasing the fibers thereof from lateral compression, and means for advancing the released pile units longitudinally of the supporting means while applying a force for promoting lateral expansion of the released units into a continuous assembly of fibers, prior to application of the backing. Procedure wherein an assembly of pile fibers is advanced in a given direction for application of a backing, including the steps of distributing a plurality of the aforementioned pile units in a direction transverse to the given direction, releasing them from lateral compression, and advancing them in the given direction while applying a force for promoting expansion of the released pile units.
