ABSTRACT:
A cleaning device and method for making which is constructed from a flexible base member of thermoplastic material to which a plurality of fibers are fused and protrude therefrom, and formed into a curvilinear configuration such as a helix-like, or U-shaped-like configuration. The method includes the steps of heating the base until it is softened and bent to a U-shape like configuration and then cooling the base member, or helically winding the base onto a rotating mandrel; stopping the mandrel and severing an end of the base member; and cooling the base member so that it retains its U-shape or helical configuration. A core member may also be inserted through the opening in the helix-like configuration and attached at one or more points of the base member permitting the cleaning device to be pushed through tubular members.
