Publication number: 20150094195Abstract: In apparatuses for automatically folding items of laundry, items of laundry of different lengths usually are folded in an irregular sequence, resulting in idling and/or delays in particular in the longitudinal-folding station (13). The invention provides for determining the length of each item of laundry (10) upstream of the longitudinal-folding station (13) and for accelerating short items of laundry as they are transported through the longitudinal-folding station (13), whereas larger items of laundry are slowed down in the longitudinal-folding station (13). Following completion of the longitudinal-folding operation, the respectively folded item of laundry is located at the end of the longitudinal-folding station (13) and, immediately following completion of the longitudinal folding, is transported away out of the longitudinal-folding station (13).Type: ApplicationFiled: September 25, 2014Publication date: April 2, 2015Applicant: Herbert Kannegiesser GmbHInventors: Jorg Sielmann, Christian Herzberg, Alexander Serikow, Lars Herzog, Rene Pleitner, Engelbert Heinz

Patent number: 8993902Abstract: 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.Type: GrantFiled: April 27, 2012Date of Patent: March 31, 2015Assignee: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz

Publication number: 20140304925Abstract: Washed laundry that has been rinsed still contains bound acidic or basic rinsing liquid. In many cases this must be neutralized. This used to be conducted on the basis of values gained from experience, which generally resulted in only partial neutralization. Herein, sample liquid is taken continuously from the neutralization chamber (18) and, after the fine filtration of same, the pH value of the sample liquid is continuously measured by a pH value measurement device (31). In this manner a pH value control system is possible which ensures an automatic and complete neutralization of the rinse liquid still bound in the laundry after rinsing.Type: ApplicationFiled: April 3, 2014Publication date: October 16, 2014Applicant: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz

Publication number: 20140303771Abstract: 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.Type: ApplicationFiled: March 28, 2014Publication date: October 9, 2014Applicant: Herbert Kannegiesser GmbHInventors: Jurgen Mocker, Dirk Littmann, Engelbert Heinz

Publication number: 20140291123Abstract: Items of laundry (10) are fed, in laundries, to a laundry-treatment device with adjacent corners (25) of an upper edge (39) hanging beneath two clip carriages (22). It is customary for the items of laundry (10) to be stored in a sorted state on an interim basis upstream of the laundry-treatment device. The invention provides for adjacent clip carriages (22) of successive items of laundry (10) to be assigned in pairs to drivers (28) of a catch conveyor (26). The invention also provides for the sagging of the upper edge (39), and the lowermost location (40) of the lower edge (42), of the item of laundry (10) to be determined by a line-measuring device (26), in order for the item of laundry (10) to be identified in this way.Type: ApplicationFiled: March 14, 2014Publication date: October 2, 2014Applicant: Herbert Kannegiesser GmbHInventors: Andreas Olivieri, Frank Schormann, Norbert Kortner, Engelbert Heinz

Publication number: 20140216111Abstract: 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.Type: ApplicationFiled: April 9, 2014Publication date: August 7, 2014Applicant: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz

Patent number: 8732995Abstract: Laundry articles are spread out by input machines in front of a feed conveyor which feeds the spread-out laundry article to a mangle. The respective laundry article is previously fed by a transfer device to a draw-on device onto which the laundry article is drawn. In known input machines, relatively complicated transfer devices are provided. According to the invention, the transfer device is provided with a rectilinear conveying section ascending to the draw-on device. The laundry article is thereby transported to the draw-on device by the transfer device in the plane in which it is transferred to the transfer device. Such a transfer device needs to have only a simple set-up. Since the laundry article remains in the plane in which it is fed to the transfer device, it can be brought by the transfer device into a favorable initial position for being drawn reliably onto the draw-on device.Type: GrantFiled: December 7, 2010Date of Patent: May 27, 2014Assignee: Herbert Kannegiesser GmbHInventors: Lars Herzog, Jurgen Sielermann, Friedhelm Mehrhoff, Engelbert Heinz

Patent number: 8707592Abstract: 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.Type: GrantFiled: February 2, 2012Date of Patent: April 29, 2014Assignee: Herbert Kannegiesser GmbHInventors: Engelbert Heinz, Wilhelm Bringewatt, Ted Andrews

Publication number: 20130283635Abstract: 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.Type: ApplicationFiled: April 13, 2013Publication date: October 31, 2013Applicant: Herbert Kannegiesser GmbHInventor: Engelbert Heinz

Patent number: 8567090Abstract: Humid waste air is produced in heated laundry machines. This humid waste air has a still relatively high temperature. In order for the energy contained in the humid waste air to be recovered, at least in part, the humid waste air is directed through a heat exchanger (12). Condensate is produced in the heat exchanger (12), and it has proven difficult, in the case of known heat exchangers (12), for this condensate to be directed away. Moreover, the humid waste air contains accompanying substances, for example fluff from the treated laundry. These accompanying substances are deposited in known heat exchangers (12), which adversely affect the efficiency of the heat exchanger (12) over time. The invention makes provision for the heat exchanger (12) to be equipped with upright heat-exchanger plates (13), from which the condensate can run off. The condensate can then be discharged in a specific manner out of the heat exchanger (12).Type: GrantFiled: October 28, 2009Date of Patent: October 29, 2013Assignee: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz

Publication number: 20130239433Abstract: 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.Type: ApplicationFiled: March 5, 2013Publication date: September 19, 2013Applicant: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz

Patent number: 8407919Abstract: A method for the effective recovery of as large a portion as possible of the energy in the waste heat of a trough mangle (10) or other launderette machines. To this end, provision is made for a portion of the energy contained in the waste heat to be recovered by cooling the waste heat in a heat exchanger (14), with the waste heat being cooled to such an extent that it falls below the dew point and condenses, with the result that the energy released during condensation and at least a large portion of the energy from the condensate can also be recovered. In this way, it is possible for up to half the residual energy in the moist waste air from a trough mangle (10) and the waste gas from a heating device to be recovered and reused again.Type: GrantFiled: February 6, 2008Date of Patent: April 2, 2013Assignee: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz

Patent number: 8327484Abstract: A tunnel finisher in which the articles of clothing (14) are impinged on with steam pulses in a discontinuous fashion. This lowers the steam requirement. It is additionally provided that other points of the article of clothing (14) are continuously impinged on with steam, as a result of which no damage to the articles of clothing (14) occurs during the steam impingement. It is finally provided that transport hangers (15), on which the articles of clothing (14) hang while being transported through the tunnel finisher, are rotated in opposite directions, as a result of which halves of adjacent articles of clothing (14) alternately assume relatively large and relatively small spacings relative to one another. In this way, the articles of clothing (14) can be impinged on effectively and with steam.Type: GrantFiled: April 17, 2011Date of Patent: December 11, 2012Assignee: Herbert Kannegiesser GmbHInventors: Jurgen Wolf, Engelbert Heinz

Publication number: 20120260434Abstract: 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.Type: ApplicationFiled: June 20, 2012Publication date: October 18, 2012Applicant: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz

Publication number: 20120233785Abstract: 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.Type: ApplicationFiled: March 14, 2012Publication date: September 20, 2012Applicant: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz
