There are already such machines in industry (in garment-making, hotels etc). The challenge is that they are typically specialised towards specific types of garment. Nobody in industry really needs a generic machine; but that's the only configuration that the home market will consider. The only sub-niche big enough that could maybe sustain a specialised machine in the home is "shirts and trousers" - but there the real annoyance is ironing, not folding.
