An apparatus (10) for forming multi-filament tufts for use in a brush seal includes a support (14) for retaining an end of a skein (16) of aligned wires or fibers and a glue reservoir (15) dimensioned to receive the skein end. The support (14) and the reservoir (15) being relatively movable whereby the end can be inserted in the glue reservoir (15) so that the adhesive can adhere the wires or fibers at the end to form the tuft. A cutter (13) is also provided for cutting the wires or fibers to length after the wires and fibers are retained by the support (14).
