Abstract: A process is provided for producing a multi-layered flat fibrous structure, especially a floor covering, having a surface or wear layer, a base or carrier layer and optionally further layers. The base or carrier layer is first produced from a multi-layered non-woven fabric in a mechanical non-woven formation device. Elements forming the surface or wear layer are then applied to the base or carrier layer. Before application, a distribution of the elements which differ in terms of their geometrical shape is standardized in such a way that the surface or wear layer is substantially repeat-free. The elements forming the surface or wear layer are then joined at least to the base or carrier layer.

Abstract: A cleaning device is provided for cleaning pipes and receptacles. A handle is disposed on one end of the post, and a cleaning head is disposed on the other end. The cleaning head has at least one cleaning element. The cleaning head has a longitudinal section with an outer contour that is rotationally symmetrical to the longitudinal axis of the cleaning head. At least a portion of the outer contour has a circumferential projection and/or a reduced diameter section.
