Abstract:
A process for manufacturing ring-shaped brush seals having inclined bristles, the process comprising the acts of:a) providing at least one ring-shaped brush seal having radially extending bristles of a length which in combination with an inclination of the bristles with respect to a radii of the ring-shaped brush seal leads at least substantially to a desired brush diameter;b) 1) positioning the at least one brush seal and at least one heatable annealing wall of an annealing device relative to one another so that free ends of said bristles, while the bristles are bent, rest against the annealing wall;2) rotating the at least one brush seal and the at least one heatable annealing wall relative to one another until the bristles are inclined with respect to the radii of the ring-shaped brush seal in its ring plane by a defined inclination angle;c) heating the annealing wall to a defined annealing temperature of said bristles;d) maintaining the temperature of the heated annealing wall for a defined time period suitable for annealing said bristles, ande) removing the at least one brush seal from the annealing device.
