Abstract

1397341 Boots &c SHOE & ALLIED TRADES RESEARCH ASSOCIATION 5 Nov 1973 [8 Nov 1972] 51590/72 Heading A3B. A method of treating a lasted shoe upper to improve the shape retention of the upper after the last has been slipped includes the stages of first subjecting the lasted upper to a dry heat treatment at an elevated temperature and subsequently subjecting the lasted upper to a steam treatment in a saturated atmosphere at a temperature not less than 85‹C, the lasted upper being partially cooled between the two treatments. The dry heat treatment may include treatment in hot circulating air and/or a radiant heat treatment. The elevated temperature of the dry heat treatment is within the range 100‹ to 180‹C, preferably in the range 110‹ to 130‹C for leather uppers and in the range 140‹ to 180‹C for poromeric uppers. The duration of the dry heat treatment is such that the upper attains a temperature higher than that prevailing in the steam treatment zone, e.g. about 3 minutes. The cooling may be carried out by subjecting the upper to a blast of cold air or to ambient air, and the duration is such as to cool the upper not more than 20‹ below the temperature of the steam treatment, e.g. about 21 seconds. The steam treatment is conducted at a temperature of above 85‹C, preferably 90‹ to 95‹C, for about 1 minute. The method may be carried out using apparatus consisting of a conveyor which conveys the uppers through tunnels defining the treatment zones. Alternatively the apparatus described in Specification 1039296 may be modified to carry out the method.
