  • Patent number: 8276292
    Abstract: The use of at least one central heat exchanger to extract and dry the heat energy released by laundry machines, in particular their gland steam. The energy thus recovered can be fed back to the laundry machines as hot air or hot water. This represents a significant reduction in the energy requirements of laundry machines as laundry machines discharge a great amount of unused energy into the environment, which, particularly in light of rising energy prices, represents an unnecessary operational cost for a laundry.

  • Publication number: 20120233785
    Abstract: A method and apparatus for washing items of laundry that makes provision to continuously filter the treatment liquid during the washing operation. As a result, interfering attendant materials in and on the treatment liquid are successively removed during the washing operation, which increases the efficacy of the washing operation. Provision is preferably made to remove both lighter constituents, such as foam and lint, from the treatment liquid and also to filter heavier constituents, such as impurities washed out of the items of laundry, from the treatment liquid using the same filter. The same filter can also be used, after the end of the washing operation, to filter the treatment liquid to be let out and to temporarily store the treatment liquid in a collecting tank before the filtered treatment liquid is reused. The invention thus permits multiple functions of the filter.

  • Publication number: 20120198736
    Abstract: A spiral wrapping for an ironer roller for a chest ironer. Chest ironers have at least one rotatably drivable ironer roller, the lower half of which is surrounded by a stationary ironer bed. The ironer roller is surrounded by an outer spiral wrapping which comes into contact with the item of laundry to be treated. The spiral wrapping is provided with an outer layer produced from a coarse woven fabric which has a higher coefficient of friction. The coefficient of friction of the coarse woven fabric does not alter as the age of the spiral wrapping increases. This means that even in the case of older spiral wrappings, there is sufficient frictional engagement between the spiral wrapping, namely the outer layer, and the item of laundry to be smoothed out.

  • Patent number: 8225445
    Abstract: The invention makes provision for the final wash liquid from the washing device to be separated from the items of laundry in a water-removal device, specifically together with a large portion of the final wash liquid bound in the items of laundry. The items of laundry are then rinsed in the water-removal device. Following this, the rinse liquid is routed away from the items of laundry. The final wash liquid and the rinse liquid are temporarily stored in separate storage tanks and returned to the subsequent wash process in a deliberate manner. A mixture of at least a portion of the final wash liquid and the rinse liquid is fed particularly to the prewash zone in order to prewash the next batch of items of laundry.

  • Publication number: 20120099947
    Abstract: A reliable operation for sorting items of laundry automatically. For this purpose, provision is made for a plurality of simultaneously gripped items of laundry to be separated once they have been gripped by a gripping arrangement (20). Reliable separation of an item of laundry is followed by the item of laundry being measured in the straightened-out state on a conveyor. Preferably the distance between two diagonally opposite corners of the item of laundry on the conveyor is determined. This gives rise to very precise automatic measuring always just of a single item of laundry.

  • Patent number: 8142129
    Abstract: Items of laundry have to be stretched out by a spreading device (14) before they are inserted into a mangle or any other laundry treatment device. To this end, the spreading device (14) has spreading clips (15) which can be moved away from one another. In the case of relatively large items of laundry, the spreading clips (15) have to cover a relatively large distance in order to spread out the item of laundry. This reduces the insertion rate. The invention provides for the items of laundry to be preliminarily spread out before being passed to the spreading clips (15), so that the spreading clips (15) receive the item of laundry in a state in which it is already virtually spread out. The spreading clips (15) only have to cover a small residual distance in order to spread out the item of laundry completely. As a result, the spreading device (14) can spread out the item of laundry very quickly.

  • Publication number: 20120060564
    Abstract: An inline washing system to be formed from a tunnel-type washing machine (10) which only washes the items of laundry. Rinsing and also water removal are then performed in the downstream water-removal press (18). It has been found that the rinsing performance is better and fresh water can be saved as a result of this. It is therefore also possible to wash relatively small amounts of laundry using a tunnel-type washing machine (10) in an economical manner because the tunnel-type washing machine (10) can be designed without a rinse zone.

  • Publication number: 20110142576
    Abstract: Laundry articles (20) are spread out by means of what are known as input machines in front of a feed conveyor (27) which feeds the spread-out laundry article (20) to a mangle. The respective laundry article (20) is previously fed by a transfer device (23) to a draw-on device (24) onto which the laundry article (20) is drawn. In known input machines of this type, relatively complicated transfer devices (23) are provided. According to the invention, the transfer device (23) is provided with a rectilinear conveying section ascending to the draw-on device (24). The laundry article (20) is thereby transported to the draw-on device (24) by the transfer device (23) in the plane in which it is transferred to the transfer device (23). Such a transfer device (23) needs to have only a simple set-up.

  • Patent number: 7610644
    Abstract: The invention makes provision for the weight of the contents of the drum to be continuously determined. As a result, the weight of the dry laundry in the drum and the weight of the liquid required for washing can be determined. The weight determination also makes it possible to determine the residual moisture content of the laundry, identify an unbalance and/or assist batch division. The spin dryer (10) or laundry centrifuge preferably rests on its feet (19) by means of weight sensors, that is to say is weighed. In this way, the weight of the contents of the drum as well as dynamic forces which are produced when the loaded drum is driven in rotation can be established in a simple and reliable manner.
