Abstract
Automatic carding machine for uppers including a carriage upholding the upper to be scraped and travelling longitudinally along guides constrained to the top of the machine. The upper sector of the carriage runs on similar guides transversely. The movements can be performed simultaneously by means of independent activation members and the carriage translation speed as well as the upper sector are programmable so that the card can intervene in variable measure on the different peripheral parts of the upper arranged on the carriage. The tool or card automatically reverses its direction of rotation so as to roughen the back of the shoe from the outside toward the inside.
