  • Patent number: 10920350
    Abstract: A felting needle has a working part that extends lengthwise along a part of the longitudinal extent thereof. The needle has a cross-sectional area which extends in the radial and circumferential directions of the felting needle and forms the cross-sectional area of the working part for much of the length thereof and at least one barb which penetrates into the working part which is formed by an incut running from the outer surface of the working part towards the interior of the needle. The needle includes at least one bulge which projects beyond the circumferential surface of the felting needle in the working part thereof. The bulge extends lengthwise only along a part of the working part and has volume constituents that do not belong to the barbing bead of the barb. The barb adjoins the outer surface of the bulge lengthwise along the felting needle.

  • Patent number: 8621700
    Abstract: The invention relates to a mobile sweeper comprising a housing, in which a sweeping roller driven by an electric motor is mounted for rotation, and a sweepings container for receiving sweepings, wherein there are mounted on the housing adjacent to the sweeping roller two front supporting wheels and at a distance from these at least one rear supporting wheel, each for rotation about an axis of rotation. In order to further develop the sweeper such that with the occurrence of surface unevennesses, there is no risk of the sweeping roller becoming blocked or of the sweeper tilting, it is proposed in accordance with the invention that the axis of rotation of a first front supporting wheel be arranged coaxially with the axis of rotation of the sweeping roller and, in relation to the main direction of movement of the sweeper, offset from the axis of rotation of the second front supporting wheel.

  • Publication number: 20090308554
    Abstract: This invention relates to a device for transferring a material web, particularly a web made of paper, board, tissue, or other pulp. In order to transfer the material web and, preferably, a supporting belt from a first supporting surface to a subsequent supporting surface, a pick-up box with a pick-up zone to lift the material web off the first supporting surface and a stabilizer box with a stabilizing zone to stabilize the material web are arranged before the subsequent supporting surface. Suction can be applied to the pick-up zone and the stabilizing zone by means of a vacuum source. A further zone to separate the vacuum in the pick-up zone from the vacuum in the stabilizing zone is located between the pick-up zone and the stabilizing zone. This invention also relates to a process for transferring a material web performed with the device according to the invention.
