Ironing machine
An ironing machine , also known as a hot iron (cylinder shortage, bowl shortage) or roller iron , is a device from laundry technology and is used for textile care . Service companies that lack laundry for private households are often generally referred to as hot ironers . The historical predecessors of the hot ironers are the cold ironers . The generic term of deficiency (or lack of laundry ) summarizes hot and cold deficiencies.
Working method and area of use
The textiles are drawn in by means of a large, fabric-covered roller and pulled through a heated trough made of metal under high pressure. Depending on the variant, either the trough or the roller is raised and lowered. The speed of rotation of the roller and the working temperature can be varied. Textiles are smoothed and dried in one operation. The process is particularly suitable for flat linen such as sheets, duvet covers , pillow cases, tablecloths or tea towels. Ironing items of clothing requires special care and experience as the machine can crease or even damage them. Therefore, clothes are generally not ironed with an ironing machine.
Constructive details
Commercial flatwork ironers are mainly used in medium-sized and upscale laundries. There are ironers of various types that differ in width, type of laundry feed, heating technology, number and structure of the rollers. Common sizes today range from 800 millimeters to 2000 millimeters roller diameters and working widths of up to 4000 millimeters. The number of rollers per bowl ironer is usually limited to four. Such commercial machines are heated by steam or thermal oil, which is heated directly in the machine using a gas burner. The resulting water vapor is led outside with fans via a possibly existing heat recovery system.
Household ironing machines can also have rollers that are more than 100 cm wide. For easier storage, they can often be folded up and stored upright. Modern versions also have a built-in boiler. Steam is generated in this, which is brought to the textiles through a gap or a small additional roller - this allows a type of steam ironing. The trough or the roller can be heated. In the past, gas was often used for heating, now mostly electrically. The trough can also be heated with steam or thermal oil. In the case of cylinder shortages, the laundry is fed past a heated, rotating cylinder with "ironing straps" (or belts) and pressure rollers.
Manufacturer
Ironing machines are manufactured by manufacturers of household appliances and, for the professional sector, by companies in the textile machine industry, heat technology and mechanical engineering. Domestic models cost around 600 to 2000 euros. For large-scale applications, the machines can cost over 22,000 euros.
