Norge dryers put the blower fan after the heat source and before the drum instead of after both heat and drum (vacuum principle) as with most other makes. This gave a blowing effect inside the drum and made it "pressurized" for 'Billowing Currents of Air'. It worked well except with a long vent and/or when the dryer aged and seals began to fail. The pressurized dryer leaked lint terribly, flocking the laundry room with lint like a holiday tree.
One neighbor of ours had a mid-50's Norge dryer and if you opened the door while it was running, the strong blower would actually blow small socks and hankies out onto the floor. Their basement was flocked, floor to ceiling, every vertical surface, just like a xmas tree. I had a 67 Montgomery Wards washer and dryer pair for a little while, the 8 cubic foot drum and "billowing currents" dried very quickly. After every cycle, there was a tuft or two of lint peeking out from under the door opening that had leaked out around the filter. Perhaps they meant to sell more vacuums with dusting attachments.
Heavy as tanks, the Norge dryers were quite a contraption and some rather noisy. The whole machine would give a shudder and a rumble on start-up, and you could hear that blower come up to speed and pressurize the system. All in all, they weren't the worst dryer ever built, especially if you had an open back porch to use it on.
