Mangle vs. Ironer
Makers of rotary ironers fought a battle to have their appliances called anything else but a mangle. Primiarly this was done to over come negative associations with that device which was known for harming not just textiles, but body parts as well.
Strictly speaking at least in English usage a mangle refers to "wringer" used to remove water by squeezing. A rotary iron uses a rotating covered and padded cylinder to move laundry alone a heated shoe or chest.
