Abstract
This invention relates to a method of forming brush seals and to brush seals themselves. Thus a back plate 10, which defines an anchor recess 11, a reservoir recess 12 and a land 13 is laid horizontally. A bristle pack 14 is then laid on top of the back plate 10, so that one end 15 overlies a recess 11 and the other, 16, projects beyond the land 13. The bristles are then clamped in position by clamp 21 and epoxy resin is poured into the recess 11 as indicated by the arrows. A mold is introduced over the recess. Once the resin is cured, the mold can be removed and it will be noted that excess epoxy resin has fallen into the recess 12 preventing resin wicking beyond the land 13 and interfering with the performance of the bristles.
