ABSTRACT:
An apparatus for forming medical needle holder assembly employing a generally tubular needle holder, a filter element constituted by a wad of a lengthy filament yarn of snythetic resin and a generally tubular filter retainer adapted to be received in the needle holder with the filter element fitted in the needle holder. The needle holder assembly is completed by holding the needle holder and the filter retainer in positions longitudinally aligned with each other, positioning a predetermined length of filament yarn between the needle holder and the filter retainer, producing a unidirectional stream of air flowing away from the filament yarn thus positioned toward the foremost end of the filter retainer for moving the filament yarn onto the foremost end of the filter retainer, and moving the combination of the filter retainer and the filament yarn toward the needle holder, and forcing the filter retainer into the needle holder so that the filament yarn which has been in a loosely tangled condition is compacted into wad form within the needle holder.
