Patentansprüche:Patent claims: 1. Spaltdichtung für Dampfturbinen, dadurch gekennzeichnet, daß der dem Spalt zunächst liegende Dampfteil durch sprunghafte Verkleinerung des Austrittswinkels der vor dem Spalt liegenden Schaufeln eine zusätzliche Beschleunigung in Umfangsrichtung erhält. go 1. Gap seal for steam turbines, characterized in that the steam part lying next to the gap receives an additional acceleration in the circumferential direction by abruptly reducing the exit angle of the blades in front of the gap. go 2. Spaltdichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Schaufeln an der Austrittsseite kurz über dem Fuß angeschnitten sind und der von dem Fuß entfernt liegende Teil umgebogen ist.2. gap seal according to claim 1, characterized in that the blades are cut on the exit side just above the foot and the part that is remote from the foot is bent over. 3. Spaltdichtung nach Anspruch 1 und 2, dadurch gekennzeichnet, daß der umgebogene Teil der Schaufeln auf die ursprüngliche axiale Ausdehnung durch Anfügen von Baustoff verlängert ist.3. gap seal according to claim 1 and 2, characterized in that the bent part of the blades on the original axial expansion is extended by adding building material.
