How do trough calenders work?
Trough calenders are also known as hot calenders, because they use heat and pressure to smooth out laundry. Inside the machines are one or more heated rollers and troughs. The laundry is drawn into the troughs while the rollers rotate, removing wrinkles from the laundry under pressure. The laundry is smoothed out in the trough-type ironing machine. The speed of the rollers and the temperature of the troughs can be adjusted as needed.
Which fabrics can be mangled?
Because of the way they work, trough-type wringers are ideal for large items of laundry such as bedding, sheets, tablecloths, table runners, napkins, and other flat linens.
