Abstract
The invention relates to an intermediate component for protecting hangers associated with electrostatic coating processes. The component is an electrically conductive, pliable, tubular member, and inexpensive relative to the hanger which it serves to protect. The component lessens the cost associated with traditional hanger cleaning and preserves hanger life and integrity. The tubular member may have a longitudinal slit for installing the member over a cross bar of a hanger.
Claims10
A method of electrostatic coating, comprising the steps of:
- engaging a pliable, electro conductive intermediate cap having a bore extending over substantially the entire length of the cap directly over a substantially rigid electrically conductive hanger, at least a portion of the hanger and the intermediate cap being disposed in a generally horizontal orientation, and the intermediate cap forming a cover layer of substantially uniform thickness over the hanger;
- hanging an article to be coated over the hanger so that the article is suspended from the hanger and the intermediate cap forms a protective cover layer disposed between the hanger and article and in direct contact with both the hanger and the article;
- carrying out an electrostatic coating process on the article;
- and
- repeating the steps with other articles to be treated after recycling or replacing the intermediate cap to remove any unwanted deposits of the coating process accumulated on the intermediate cap.

A method of electrostatic coating, comprising the steps of:
- taking a pliable, electro conductive intermediate member having a bore extending over substantially the entire length of the member and at least one open end;
- engaging the intermediate member directly over a substantially rigid electrically conductive hanger, at least a portion of the hanger and the intermediate member being disposed in a generally horizontal orientation, and the intermediate member forming a cover layer of substantially uniform thickness over the hanger;
- hanging an article to be treated over the intermediate member so that the article is suspended from the hanger and the intermediate member forms a protective cover layer disposed between the hanger and article and in direct contact with both the hanger and the article;
- carrying out an electrostatic coating process on the article;
- and
- repeating the steps with other articles to be treated after recycling or replacing the intermediate member to remove any unwanted deposits of the coating process accumulated on the intermediate member.

An electrostatic coating method, comprising the steps of:
- taking a pliable, electro conductive intermediate member having a bore extending over at least substantially the entire length of the member and at least one open end;
- engaging the intermediate member directly over a substantially rigid electrically conductive hanger, at least a portion of the hanger and the intermediate member being disposed in a generally horizontal orientation, and the intermediate member forming a cover layer of pliable electro conductive material and substantially uniform thickness directly over the hanger;
- hanging an article to be coated directly over the electro conductive intermediate member so that the article contacts only the electro conductive intermediate member and is suspended from the hanger, whereby the intermediate member forms a protective cover layer disposed between the hanger and article and in direct contact with both the article and hanger;
- carrying out an electrostatic coating process on the article;
- and
- repeating the steps with other articles to be treated after recycling or replacing the intermediate member at periodic intervals to remove any unwanted deposits of the coating process accumulated on the intermediate member.
