This is some laundry becoming dry on a "stewi".
His inventor died in April 2009. It was a great revolution for women in the middle of the 20th Century.
Stewi were made in Winterthur, Switzerland => this explains the "wi" at the end of the name. The "Ste..." is the beginning of the name of the company but I can't remember. Maybe "Steiner" or "Steinmann".
