A trouser press “is an electrical appliance used to smooth the wrinkles from a pair of trousers (pants in Australia, Canada, South Africa and the United States)”. Picture is here http://store.makro.co.uk/images/PRODUCT/medium/365515.jpg.
The press works on the bottom two-thirds of the trouser legs. The trousers are held between an optionally heated surface and a wooden board. Heat is typically applied for 30 mins.
What halachic issues are involved in the use of a trouser press in the nine days? Does it make any difference if the press is used every weekday of the year? What are the issues if the trousers are put the in the press but the heat is not applied?
