Abstract
The invention relates to a device and a corresponding method for manufacturing brush seals with obliquely positioned bristles. The method comprises the following steps: As the first step, a metal filament or wire () comprising a material for bristles is wound over two wire cores () disposed at a distance from and running parallel to one another, to form a tightly packed metal filament or wire package (). As the next step, the metal filament or wire package () is fastened to at least one wire core (). Then the region around at least one of the two wire cores () is locally heated. Subsequently, at least one of the two wire cores () is displaced.
