  • Patent number: 6299824
    Abstract: A process and arrangement for manufacturing brush-type seals having inclined bristles provides at least one ring-shaped brush-type seal having radially extending bristles of a length which, by way of the inclining of the bristles with respect to the radii of the ring-shaped brush-type seal leads at least essentially to the desired brush diameter; positions the at least one brush-type seal and at least one heatable annealing wall of an annealing device relative to one another so that the free bristle ends, while the bristles are bent, rest against the annealing wall, and simultaneously or subsequently rotating the at least one brush-type seal and at least the heatable annealing wall relative to one another until the bristles are inclined with respect to the radii of the ring-shaped brush-type seal in its ring plane by a definable angle; heats the annealing wall to a definable temperature; maintains the temperature of the heated annealing wall for a definable time period; and removes the at least one brush-type

  • Patent number: 5066024
    Abstract: A brush-type seal has a wire bundle which is bent in a U-shape and is surrounded by a radially inward slotted ring shaped tube and by a housing consisting of two connected support rings. Application and maintenance of clamping forces is possible and is provided for to the ring shaped tube through the support rings. Attachments are provided on one supporting for fastening at a housing. The support rings are connected by welding at a welding joint which is spaced from the slotted tube which directly contacts the wire bundle.
