Abstract
A method of manufacturing a brush includes providing a core wire section having a proximal end and a distal end, and an integral tip on the distal end, forming a bristle element having a throughbore, and inserting the core wire section into the throughbore until the bristle element is received on the core wire section.
Claims13
A brush, comprising:
- a core section including at least two leg members twisted about one another in a helical configuration, the core section having a proximal end and a distal end, and a tip formed on the distal end, the tip being enlarged such that a diameter of the tip is greater than a diameter of the core section;
- a plurality of discs received on the core section, the plurality of discs extending axially along the core section to define a brush head, each disc including a hub body with an aperture formed therethrough to encompass a portion of the core section and a plurality of spaced tines extending radially from the hub body;
- and
- a distal tip received on the enlarged tip of the core section via a ball-and-socket connection,
- wherein upon placement of the distal tip on the enlarged tip of the core section, the hub body of a disc of the plurality of discs that is closest to the enlarged tip is disposed in the ball-and-socket connection and covered thereover by the distal tip.

A method of manufacturing a brush, comprising the steps of:
- providing a core section having a plurality of leg portions twisted in a helical configuration, a proximal end and a distal end, and a tip on the distal end;
- positioning a plurality of disc elements on the core section, the plurality of disc elements each having a throughbore through which the core section extends;
- and
- trimming the plurality of disc elements after positioning the plurality of disc elements on the core section in the stacked arrangement;
- wherein the tip forms a position stop preventing the plurality of disc elements from sliding off the distal end of the core section;
- wherein the core section includes a plurality of bristles anchored between the plurality of leg portions;
- wherein the plurality of bristles inhibit axial and rotational movement of the plurality of disc elements on the core section.
