<p>The edges of a belt or other article of manufacture ("M") made of leather, hide or similar materials are treated with a protective coating applied through painting or waxing, and submitted to a step of surface finishing the protective coating. To this aim, the edge of the article of manufacture ("M") is repeatedly submitted to a beating step by a tool (7) carrying out a vibratory motion against the edge of the article itself, by means of an abutment surface (8) conforming in shape to the crosssection outline of the edge of the article of manufacture ("M"). The beating tool (7) is heated to a temperature in the range of 50°C to 250°C. Powered guide rollers (5a, 5b) disposed in parallel rows engage the article of manufacture ("M") at the opposite longitudinal edges, to cause moving forward of said articles on the line of action of the tools (7) . The guide rollers (5a, 5b) further produce a rolling operation on the edges of the article ("M") submitted to the action of the beating rollers (7).</p> |
