The principal functions of an ironer and press are the same as the function of a domestic hand iron. The heat of the iron removes residual water, and the pressure removes creases. Items that are typically ironed are:
• Bed sheets.
• Pillow cases.
Textiles that are ironed are mostly flat, and are therefore called flatwork. There are two types of ironer for handling different types of linen: chest ironers and cylinder ironers.
