ABSTRACT:
A method of manufacturing outer footwear such as a shoe comprises the step of dry or moist heat setting a lasted shoe (9, 10) by partially or totally immersing it in a fluidized solid material (2) in a bath (1). It is now proposed that the lasted shoe (9, 10) should be enclosed in a sleeve (7) of flexible impervious material, the upper open end (6) of the sleeve being fixed with respect to the bath (1) while the remainder of the sleeve including its closed end (7a) is partially or totally immersed in the fluidizable material. Apparatus for the performance of the method comprises a plurality of sleeves (9) fitted as aforesaid with their open upper ends (6) secured to the top (5) of the bath (1) and their lower closed ends (7a) secured by hooks (8) to the floor of the bath. The material is fluidized by admission of heated air to the bottom of the bath of which the top cover (5) has an air outlet (5b) including a filter for preventing escape of fluidized material.
