ABSTRACT:
A device for forming lengths of adhesive tape into tubes including a mandrel having an axis and a multiplicity of radially outwardly projecting resilient bristles having tips defining at least the major portion of a periphery around the axis in the shape of a tube to be formed. The tape is wrapped around the periphery of the mandrel and the ends of the tape overlapped to form a tube having an axially extending seam. A ring is then pressed against one end of the formed tube to slide it axially off of the bristles and mandrel.
