20080289119 | METHOD FOR THE WET TREATMENT OF ITEMS OF LAUNDRY - 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. | 11-27-2008 |
20080295257 | METHOD FOR THE WET TREATMENT OF ITEMS OF LAUNDRY - According to the invention, provision is made for at least one treatment additive in the treatment liquid to be reused to be measured during operation of the pass-through washing machine and possibly the spin dryer which is arranged downstream of said pass-through washing machine. As a result, it is possible to establish whether the treatment liquid still contains a sufficient quantity of treatment additives before said treatment liquid is reused. On account of the established concentration of the respective treatment additive, the treatment additive can be deliberately added in a metered manner, so that the treatment liquid to be reused contains a sufficient concentration of the respective treatment additive. | 12-04-2008 |
20090092464 | METHOD AND APPARATUS FOR FEEDING ITEMS OF LAUNDRY TO A LAUNDRY TREATMENT DEVICE, IN PARTICULAR A MANGLE - Items of laundry have to be stretched out by a spreading device ( | 04-09-2009 |
20090100607 | METHOD AND APPARATUS FOR THE WET TREATMENT OF LAUNDRY ARTICLES - In the washing and drainage of laundry articles, treatment liquid which contains still unspent wash-active substances occurs at the end of the washing operation. These substances have hitherto been conducted, if appropriate after neutralization, into the discharge together with the treatment liquid. This known procedure has an adverse effect on the efficiency of the washing operation. According to the invention, spent wash-active substances are removed from the treatment liquid separated from the laundry articles after the washing operation. This takes place by means of precision filtration, in which only the spent wash-active substances which are larger due to the absorption of dirt from the washing operation are filtered out of the treatment liquid, but not the unspent wash-active substances having a smaller particle size. These can be reused, together with the treatment liquid, for a subsequent washing operation. | 04-23-2009 |

20120198736 | Spiral wrapping for an ironer roller of a chest ironer and a chest ironer provided with such a spiral wrapping - 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. | 08-09-2012 |
20120233785 | METHOD AND APPARATUS FOR WASHING IN PARTICULAR ITEMS OF LAUNDRY - 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. | 09-20-2012 |
20120240342 | METHOD FOR TREATING LAUNDRY AND INLINE WASHING SYSTEM - 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. | 09-27-2012 |
20120260434 | METHOD FOR THE WET-TREATMENT OF ITEMS OF LAUNDRY - 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. | 10-18-2012 |
20120298427 | METHOD FOR LOADING A LAUNDRY MACHINE - 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. | 11-29-2012 |
20130239433 | METHOD FOR DRYING LAUNDRY AND DRYER - A method for providing fresh air fed through a fan to a burner of a dryer, thereby charging the burner, when the dryer is operated with recirculating air. In commercial dryers in which the drying air is heated by a burner, it is customary to reuse the moist air leaving a drum containing the laundry to be dried as recirculating air. The recirculating air component is increased with increasing drying of the laundry. At the end of the drying operation, when the moist air no longer contains as much moisture as at the start, the moist air is used as recirculating air. The burner then no longer gets enough combustion air, which leads to an incomplete combustion. The dryer can be operated with a higher recirculating air component, an optimal combustion being guaranteed through the charging of the burner with fresh air. The invention permits more economical drying. | 09-19-2013 |
20130283635 | METHOD FOR DRYING ITEMS OF LAUNDRY - Dryers are intended to operate in a manner in which energy is saved and laundry is treated gently. To this end, it is necessary to regulate the drying process in an optimum manner on the basis of the drying parameters and to find the time point for terminating the drying process which is most favourable for the laundry in question. The invention makes provision for at least one factor to be formed from a plurality of drying parameters and for the drying process to be terminated and/or for the drying process to be regulated on the basis of this factor. The factor can be formed by computer from a few drying parameters which are easy to detect, and regulation can be carried out in a simple manner with little expenditure on the basis of the factor by way of simple comparison with a setpoint value. | 10-31-2013 |

20140303771 | METHOD FOR SORTING LAUNDRY ITEMS, IN PARTICULAR DIRTY LAUNDRY ITEMS - A method for storing scanned information concerning a relevant laundry item in a data storage means which is assigned to a carrier holding the laundry item. The laundry item is assigned to a storage means or an intermediate storage means with the carrier comprising its information by a conveying system. The laundry items are sorted by way of their individual information stored on the carriers, moved into corresponding storage sections of the storage means and at the same time are both sorted and formed into laundry batches. The laundry batch then includes laundry items which require a same treatment. The laundry batch can then be supplied, for example, to a continuous-batch washing machine where the laundry items of the laundry batch are washed and, where applicable, subject to further treatments in the manner predefined according to their information. The sorting of the laundry items is automated to a large extent. | 10-09-2014 |
20140304925 | METHOD FOR THE WET-TREATMENT, PREFERABLY THE WASHING, OF LAUNDRY - Washed laundry that has been rinsed still contains bound acidic or basic rinsing liquid.
