  • Patent number: 11760597
    Abstract: A web-tension-measuring device has two plates, which can be rotated relative to one another about an axis of rotation, to be precise such that the one free end of the one plate can be moved towards, or away from, the corresponding, opposite free end of the other plate. A force transducer is arranged in the region of the free ends of the two plates and outside the axis of rotation. The force transducer is configured, during movement of the free ends of the two plates towards one another, to detect a corresponding compressive loading arising from the movement and, during the movement of the free ends away from one another, to detect a corresponding tensile loading between the two plates.

  • Patent number: 7951268
    Abstract: An apparatus for the production of a fibrous web, especially a tissue or hygienic web, the fibrous web runs through a press nip which is formed by a press unit and a backing roll and the web is subsequently run through a creping nip which is formed by the backing roll and a creping roll around which a textured belt is looped. Moreover, the creping roll is equipped with its own drive. The creping roll can be pressed against the backing roll through a pivoted lever whose pivoting axis which is parallel with the axes of the creping roll and is positioned such that the connecting line between the pivoting axis and the creping roll axis forms an angle of approximately 90° with the connecting line between the creping roll axis and the backing roll axis, when viewed in a vertical plane relative to these axes.

  • Patent number: 6214167
    Abstract: Twin-wire former for producing a fibrous material web from a fibrous suspension and process for separating upper and lower wires of the twin-wire former. The twin-wire former includes a twin-wire zone composed of a lower wire and an upper wire and a plurality of rolls including an inlet roll and an outlet roll. The upper wire is guidable over the plurality of rolls, the inlet roll guides the upper wire to the twin-wire zone, and the outlet roll guides the upper wire toward the inlet roll. A wedge-shaped inlet zone is formed between the upper wire and the lower wire and has an adjustable inlet wedge angle. An upper wire subassembly includes a drainage box adapted to receive suspension water that flows upwardly through the upper wire, and further includes a pivotable common support device, to which the drainage box and the inlet roll are mounted.
