  • Patent number: 11261562
    Abstract: A conveyor device for a folding apparatus for folding textiles includes an infeed region for a textile and an outfeed region for a folded textile. A first belt conveyor conveys the textile on a first conveyor plane from the infeed region to a first transfer unit, which feeds the textile to a second conveyor plane of a second belt conveyor. At least one second transfer unit and at least one additional belt conveyor having an additional conveyor plane are disposed downstream of the belt conveyor. At least two subassemblies, each configured as modular conveyor units are provided, into which one belt conveyor and at least one transfer unit are each integrated. The conveyor device is modularly configured, in that a plurality of modular conveyor units are disposed one atop the other and connected to each other.

  • Patent number: 9139949
    Abstract: Device for drying laundry by means of a current of air comprises a drum to accommodate the laundry and a ducting system to direct said current of air. The ducting system has a section arranged downstream of the drum, in which the current of air is directed downwards and in which is arranged a filter to capture lint from the current of air. A scraper is assigned to the filter, in order to scrape off the lint. The receptacle has a handle and two interlinked shell elements which can be separated from each other, and which define a storage volume to accommodate the scraped-off lint. According to the invention, lint thus scraped off can be removed from the device and disposed of, without the user needing to come into direct contact with the lint.

  • Publication number: 20080110042
    Abstract: A method and a device for drying wet washing that has been placed in a drier device equipped with a rotatable drum. The stream of drying air is guided in such a way that the surface of the washing to be dried that is exposed to said stream is maximised. To achieve this, the invention provides a washing spacer, at least some sections of which are flexible and on which the washing to be dried can be placed. The spacer can then be rolled up together with the washing to be dried into a preferably cylindrical form. The washing spacer and the wet washing, which is rolled with a radial distance between its layers, is connected in an air-conductive, sealed manner to the extraction opening, allowing the stream of drying air to be guided through the washing spacer and the washing to be dried. Said method is extremely effective and reduces the drying times.
