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.

摘要:
An inline washing system to be formed from a tunnel-type washing machine (10) which both rinses and removes water from the items of laundry. However, rinsing and simultaneously also water removal can also be performed in the downstream spin-dryer (18) or water-removal press. It has been found that the rinsing performance is better and fresh water can be saved on account of the invention. By virtue of the invention, it is possible to wash relatively small amounts of laundry using a tunnel-type washing machine (10) in an economical manner. The tunnel-type washing machine (10) can be designed to be shorter and also simpler if it is designed without a rinse zone.
摘要:
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.
摘要:
The washer-extractor (41) having only a single front-end opening (13) of the drums (12, 14). This opening (13) is used for loading and also unloading. The openings (13, 15) can be closed by a door (46). The door (46) can be separated from the drums (12, 14). In addition, the door (46) does not co-rotate when the inner drum (12) is rotationally driven for washing and spinning the laundry. A washer-extractor (41) of this type is characterized by its simple design and by a reliable sealing effected by the door (46), particularly when the washer-extractor (41) is arranged in the dividing wall (43).
摘要:
A method that makes provision for a volume of a batch of laundry to be ascertained in a water-removal press downstream of the washing machine. The volume of the batch of laundry can be reliably determined in a simple manner in the water-removal press, without the performance of the washing machine being adversely affected as a result. On the basis of the subsequently ascertained volume of the batch of laundry, the weight of the batches of laundry with which the washing machine is then to be loaded can be corrected such that the said batches of laundry and also subsequent batches of laundry have a volume which at least approximately corresponds to the receiving volume of the washing machine.
摘要:
In tunnel-type washing machines (10) for commercial laundries, the main-wash liquid is heated by steam in particular. This means a steam-generating system is required in the laundry. The invention makes provision for the main-wash liquid to be heated up by means of a flow heater, preferably a heating device (26) which has a gas burner (28). As a result, the tunnel-type washing machine (10) can also be used in laundries which do not have a steam generating system. The invention also makes provision for the gas burner (28) of the flow heater to be operated continuously since treatment liquid which is required for other purposes, preferably treatment liquid which is temporarily stored in a storage tank (31), is heated up after the main-wash liquid is heated up. Uninterrupted, economical operation of the gas burner (28) is ensured as a result.

The invention proposes a spin dryer which makes it possible to drain the laundry to approximately the same extent as a laundry press. For this purpose, a rotatable drum of the spin dryer is driven at a high rotational speed such that the laundry inside the drum is exposed to a centrifugal force which amounts to at least 600 times gravitational acceleration.

A washer-extractor-dryer (50), in which a plate heat exchanger (60) is arranged in the outer drum (53). During washing, the plate heat exchanger (60) is located in the washing liquid and, as a result, warms the latter up. During drying of the washed laundry, air is conducted along the outside (63) of the plate heat exchanger (60) and is thereby pre-heated before the air enters the inner drum (52) with the laundry to be dried. A pivotable flap (68) is provided in order to allow liquid to flow along the plate heat exchanger (60) during the washing mode and air to flow along it during the drying mode.
摘要:
A method for treating laundry and an inline washing machine that makes provision for water to be removed from the laundry selectively only in a water-removal press or in a water-removal press and a laundry centrifuge. Delicate items of laundry are subjected only to preliminary pressing in the water-removal press while water is then completely removed in the laundry centrifuge. In this way, a water-removal press can always be permanently arranged downstream of the washing machine and all the laundry, including delicate laundry, can pass through the water-removal press.
