Reducing machine heat and noise by a special enclosure.

Some improvements on a machine used in the steel cord industry are described. The main ergonomic problems found in a department with such machines are the high noise and heat. The noise produced by the machine and by its components was studied and an enclosure containing the most noisy parts was built. In order to reduce the heat released by the machine at the man's level ( approximately 2600 kcal/h) a system which carries the hot air up to 2.5 meters was studied. Such a system, which reduces by about 50% the heat released at the man's level, works by exploiting some of the energy absorbed by the machine itself.
