ABSTRACT:
The heat setting machine comprises a channel along which a lasted shoe upper is conveyed to be subjected to heat. The apparatus comprises a resiliently deformable member extending along and secured to one side of the channel. The resiliently deformable member, which may be in the form of an inflated bag, is arranged to extend across the channel to engage a cooperating member secured to the other side of the channel and thereby close the top of the channel. By deformation of the resiliently deformable member, the leg portion of the lasted upper of high-legged boot can be inserted between the members to be supported thereby as it is conveyed along the channel.
