ABSTRACT:
The machine comprises a plurality of substantially enclosed channels in which a lasted shoe upper is subjected to hot air blown from both sides of the channel. Conveyors carry the uppers along the channels past inlets located at a distance of from 6 to 20 cms from the center-line of the lasted upper as it passes longitudinally along the channel. This arrangement enables air to be blown on to the uppers at high velocity. Moistening means may be provided to introduce moisture into the air before it is blown on to the uppers.
