  • Patent number: 10238264
    Abstract: In an embodiment, the present invention provides a torsion wringer including: a contraction device for receiving a mop head of a mop, the contraction device having an upper part and a lower base which are interconnected by contraction lamellae, the contraction lamellae being hinged to the upper part and to the lower base such that the upper part can rotate relative to the lower base, the contraction device being movable relative to a carrier device over a distance of travel, as a result of which the upper part rotates through an angle of rotation relative to the carrier device and relative to the lower base. A reduction unit is provided so as to reduce a force which counteracts the rotation of the upper part.

  • Patent number: 10161080
    Abstract: A ventilation insert for textiles, with at least one layer, covered at least partially by an absorption material and having ventilation openings, the openings being at least partially closeable via a liquid by swelling of the absorption material, obtainable by: a) treating a layer having ventilation openings with a mixture, containing a wetting agent, initiator, polymerizable monomer or oligomers, and a cross-linking agent, as a preliminary stage for the absorption material; and b) polymerizing the monomer or oligomer to form the absorption material while forming a bonded connection between the absorption material and the layer. The ventilation insert has a relatively low thickness, a low weight per unit area, and high flexibility permanently and independently of moisture after economical production, via one layer, self-sealingly closing ventilation openings, and containing the absorption material. The absorption material is connected to the layer by bonding, at least in some regions.
