Abstract

Die Erfindung bezieht sich auf eine Vorrichtung zur Bahnspannungsregelung für eine fortlaufend bewegte Kunststoffolienbahn (1) im Zuge der Herstellung von eine Perforationsschweißnaht aufweisenden Beuteln, insbesondere Beutelrollen, wobei die Vorrichtung zur Bahnspannungsregelung dadurch störende Pfeifgeräusche vermeidet und eine optimale Regelung gewährleistet, daß ein Blasrohr (9) an seiner der Kunststoffolienbahn (1) zugewandten Seite wenigstens eine im wesentlichen parallel dazu verlaufende Wandfläche (11) aufweist, die beispielsweise Teil eines unterhalb der Kunststoffolienbahn angeordneten Mehrkantrohrs, vorzugsweise eines Vierkantrohres (9) ist.
