Abstract

Fig. 1 is a schematic view of a wire cleaning apparatus. This device cleans plating irregularities and cellulosic material left adhered to the wire, which material can cause shorts and wire breakage during the cable laminating process in which the wire is often utilized. It is necessary that full peripheral cleaning of fine wires (on the order of 0.007 inch diameter) be achieved so that an adequate supply of clean cable assembly wire is provided. Similarly, because the wire is so fine and plating of silver or other precious metal is often soft, it is important that the abrasive action not be too powerful, but sufficient at least to remove the adhered matter without damaging the plating. Therefore, close and efficient control of the abrasive effect must be included.

Alumina Cleaning of Continuous Wire

Fig. 1 is a schematic view of a wire cleaning apparatus. This device cleans plating irregularities and cellulosic material left adhered to the wire, which material can cause shorts and wire breakage during the cable laminating process in which the wire is often utilized. It is necessary that full peripheral cleaning of fine wires (on the order of 0.007 inch diameter) be achieved so that an adequate supply of clean cable assembly wire is provided. Similarly, because the wire is so fine and plating of silver or other precious metal is often soft, it is important that the abrasive action not be too powerful, but sufficient at least to remove the adhered matter without damaging the plating. Therefore, close and efficient control of the abrasive effect must be included.

The apparatus shown provides the above functions. A box 1 which is open at the top contains a pile or bed of aluminum oxide 2.

The size of aluminum oxide particles (or various grit sizes) can be changed, depending on the results desired and the size of wire being cleaned. Pivot brackets 3 are mounted on a wall of the box 1. The pivot brackets each carry an idler roll 4 made up of nylon or other similar nonabrasive material. Idler rolls 4 are grooved to retain the wire in a straight line. Pivot brackets 3 may be moved inward or outward to vary the length of wire immersed in the pile of alumina abrasive 2.

Varying the length of wire actually immersed in the bed of alumina gives a degree of control over the amount...
