Abstract
A method of treating shoe parts having a coating of a moisture-curable composition utilizes an apparatus in which a support (16) for an article, e.g. a lasted shoe S, can be supported within a chamber (30) in which the support can be enclosed. The chamber (30) is supplied with heat and moisture. More especially, the article is subjected to infra-red radiation from a heater (44) and steam is supplied to the chamber (30) such that the humidity of the atmosphere within the chamber (30) is maintained during the operating cycle at a dew point of between 50.degree. and 60.degree. C. The surface temperature of the heater (44) is between 250.degree. and 420.degree. C., preferably between 300.degree. and 380.degree. C., and the article is subjected to infra-red radiation for a period of between 5 and 25 seconds, preferably 10 seconds. Because the chamber (30) is enclosed, steam is supplied for only the first 5 seconds of the heating period.
