<p>The present invention provides a method of printing, on structural components, characters forming a group, comprising the steps of placing a percussion machine having a percussion pin upon the surface of a component on which the group of characters is to be printed, feeding the characters in the required sequence into a computer unit connected to the percussion machine, converting the characters into consecutive inter-related co-ordinate movements, and moving the percussion pin in accordance with the inter-related co-ordinate movements at a constant, preselectable vibration rate approximately vertical to the surface of the component and at the same time, parallel to the surface of the component so that the consecutive indentations produced by the tip of the percussion pin produce the desired sequence of characters. The method eliminates human selection error and a uniform imprint is obtained without the necessity of providing undersupports for the structural component. There is also provided a percussion machine adapted for use with the above method, which machine produces an invariably high quality of inscription.</p> |
