Abstract

Sometimes it is desirable to cover only portions of the surfaces on metal elements with a plating of another metal. This has been done in the past by plating the entire surface of the elements and then stripping the plating from the areas where it was not wanted.

Plating Process

Sometimes it is desirable to cover only portions of the surfaces on metal elements with a plating of another metal. This has been done in the past by plating the entire surface of the elements and then stripping the plating from the areas where it was not wanted.

The same result may be obtained more easily by plating only those surfaces where it is wanted. This is done with type bars by placing end portions to be protected against plating on a strip of adhesive tape 1 as shown. Strips of metal foil 2 are arranged on the tape to provide electrical connections to the bars. When the tape is folded over the end portions, they are sealed against the plating solution and the foil strips are held firmly against the bars to provide good contact.

After plating has been completed, the bars may be stored while still attached to the tape. This provides easy handling, a holding of the bars together in complete sets, and a protection of the covered portions against tarnishing.
