Abstract
A method of making a brush for use as a seal includes the steps of winding on a toroidal winding machine a filament or filaments of bristle material onto an annular mandrel which carries side-plates 12,14 of the seal, one on each side thereof. The bristle material is wound from a filament carrier so as to overlie the exposed faces of the sideplates at an angle of 45 DEG . After winding, further side-plates 40,41 are clamped over the bristle material and the bristles and side-plates are welded together at one edge thereof. The bristle material is then cut and the side-plates removed from the mandrel to provide two brushes with bristles projecting at an angle from the other edge of the sideplate pair. The brushes may be identical or opposite handed depending on the relative speeds of rotation of the mandrel and the filament carrier, and can be used as seals in relatively rotating machine components. The bristle material may be metallic, plastics or carbon fibres. <IMAGE>
