Abstract
A method for the production of brush seals, by first forming a linear array of contiguous, parallely aligned brush elements. The elements, each containing a multitude of bristles, are aligned in a resilient, linear support, in which the long axis of the bristles are parallel to each other. The resultant, resiliently supported array of brush elements is easily contoured to various arcuate shapes. For effecting a seal between the rotating elements of a turbine engine, the linear array is contoured in the form of a circular array, in which the free ends of the bristles in the array are joined to an annular backing ring.
