Abstract
A shroud assembly for a turbine engine includes a seal for sealing a gap between a first mate face of a first shroud segment and a second mate face of a circumferentially adjacent second shroud segment. The seal is received in first and second slots formed respectively on the first and second mate faces. The first and second slots extend axially between a leading edge and a trailing edge of the respective shroud segment. The first slot is open at the leading and the trailing edges while the second slot is open at the leading edge and closed at the trailing edge. The seal has axially extending first and second sides which are receivable respectively within the first and second slots. The seal has an axial length substantially equal to tan axial length of the shroud segments and has a cutout on the second side at a trailing edge end of the seal.
