  7. Antriebseinheit zur automatischen Bewegung von Schiebetüren nach Patentanspruch 6, dadurch gekennzeichnet, dass der Längsträger (2) eine erste Längsdichtung aus elastomerem Material (13) umfasst, die zwischen dem oberen Rand (10c) des ersten Profils (10) und der oberen Kante (11c) des zweiten Profils (11) eingesetzt ist.
  8. Antriebseinheit zur automatischen Bewegung von Schiebetüren nach einem beliebigen der vorhergehenden Patentansprüche, dadurch gekennzeichnet, dass der Längsträger (2) auch ein oder mehrere mechanische Verankerungsorgane (12) umfasst, die so aufgebaut sind, dass sie das zweite gerade Profil (11) stabil in Auflage auf dem ersten geraden Profil (10) festklemmen.
  9. Antriebseinheit zur automatischen Bewegung von Schiebetüren nach einem beliebigen der vorhergehenden Patentansprüche, dadurch gekennzeichnet, dass mindestens ein Türflügel tragender Laufwagen (3) axial verschiebbar auf einer geraden Schiene (15) angebracht ist, die ihrerseits auf einem zweiten Profil (11) mit Zwischeneinlage einer Längsdichtung (17) aus elastomerem Material befestigt ist.
  10. Antriebseinheit zur automatischen Bewegung von Schiebetüren nach Patentanspruch 9, dadurch gekennzeichnet, dass die gerade Schiene (15) über der Oberseite des unteren flachen Abschnitts (11a) des zweiten Profils (11) liegt und sich parallel zur Längsachse des zweiten Profils (11) im Wesentlichen über die gesamte Länge des zweiten Profils (11) erstreckt.
  11. Antriebseinheit zur automatischen Bewegung von Schiebetüren nach Patentanspruch 10, dadurch gekennzeichnet, dass die gerade Schiene (15) rittlings auf einer hervorstehenden geraden Rippe (16), die aus der Oberseite des unteren flachen Abschnitts (11a) des zweiten Profils (11) herausragt, fest angebracht und fixiert ist, wobei die Längsdichtung (17) aus elastomerem Material zwischen der Schiene (15) und der geraden Rippe (16) des zweiten Profils (11) eingesetzt ist.
