ABSTRACT:
An apparatus is provided with a chamber (20) into which a plurality of jets of moisture-laden air is directed through apertures (nozzles) 18. Through the chamber lasted shoes S, on the bottoms of which a coating of a moisture-curable adhesive composition has been applied, are progressively moved, supported bottom uppermost. The velocity of the air, which is re-circulated, is between 10 and 20 meters/second (measured at the apertures), its temperature is between 85.degree. C. and 125.degree.0 C. (measured at the point of impingement on the article) and its dew point not greater than 60.degree. C. The lasted shoes are subjected to this treatment for a period of 1 to 31/2 minutes.
