Abstract
A hot-gas stream (,) flows along the surface of a segment arrangement for shroud bands, in particular in a gas turbine. The segment arrangement comprises segments (,′) arranged next to one another and in each case separated from one another by a gap (,). The hot-gas stream (,), in at least one section (,) of the gap (,), has a velocity component perpendicular to the direction of the gap from a first segment (,) to a second segment (,′). In this case, in said section (,), along that edge (,) of the first segment (,) which faces the gap (,), at least one film-cooling bore (,) connects a cooling-air chamber (,), allocated to the first segment, to the surface (,) subjected to the hot-gas stream (,), and/or, in said section (,), along that edge (,′) of the second segment (,′) which faces the gap (,), at least one edge-cooling bore (,) connects a cooling-air chamber (,′), allocated to the second segment, to the inside (,′) of the gap (,).
