Method and equipment for the control and the regulation of the evaporation of a metal such as aluminum or other, in plants for metalization under vacuum.

摘要

The aluminum wire (A) advances towards a heated body (1) whose surface is incandescent for the evaporation, with feeding means of the wire at a velocity that can be set; a signal is drawn, which depends on the timing related to the formation of the drops of melted metal, and the temperature of the surface is controlled depending on said timing.
