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

Abstract: A brush for sealing a gap between a rotor/stator system comprises a rotor-concentric clamping ring whose interior chamber receives bristle bundles that project into gap. The bundles are wrapped around core ring that extends into the interior of clamping ring. The core ring has separating disks that are spaced apart from one another in the circumferential direction by an angular pitch .alpha., and by winding ribs that are wrapped by the bundles. The winding ribs connect adjacent separating disks in such fashion that as a result of the diagonal positioning of separating disks in the circumferential direction, bundles are aligned at an angle .beta. to radius R. This makes it possible to hold bristle bundles securely with a predetermined angular orientation.

Abstract: Brush seal for sealing two spaces of differing pressure (P1, P2) between a stator (20) and a rotor (10) of a turbomachine. The bristles (30) of the brush seal comprise angled bristle sections (31), of which the ends run against the seal surface of the rotor (10). In this manner, a low bristle stiffness and a low required radial structural space can simultaneously be achieved.

Abstract: A brush seal for sealing a gap between two spaces at different pressures on opposite sides of a rotor and a stator. The brush seal is formed as a plurality of bristles and the bristles are mounted in the stator to project radially therefrom, across said gap, to contact the rotor. A clamping ring clamps a stack of the bristles around an annular core in U-shaped fashion with legs of the bristles extending through an annular slot towards the rotor. The clamping ring includes a C-shaped section which clamps the bristles against the core and reverse bend portions at opposite ends of the C-shaped section. The reverse bend portions are axially spaced from one another and form the annular slot through which the legs of the bristles extend.
