Abstract

Die Erfindung betrifft eine Trockenpartie zur Trocknung einer Faserstoffbahn (1), insbesondere einer Papier-, Karton-oder Tissuebahn in Maschinen zur Herstellung und/oder Veredelung derselben bestehend aus mehreren Trockengruppen, in denen die Faserstoffbahn (1) über beheizte Trockenzylinder (2) und Leitwalzen (3) geführt wird, wobei die Faserstoffbahn (1) von wenigstens einem Band (4) der jeweiligen Trockengruppe gegen die Mantelfläche der Trockenzylinder (2) gedrückt und die Faserstoffbahn (1) an wenigstens einer Übergabestelle (5) zwischen zwei mitlaufenden Transferelementen (6,7) übergeben wird und das übernehmende Transferelement (7) eine höhere Geschwindigkeit als das übergebende Transferelement (6) aufweist.The invention relates to a dryer section for drying a fibrous web (1), in particular a paper, cardboard or tissue web in manufacturing machines and / or refining the same consisting of several drying groups, in which the fibrous web (1) over heated drying cylinders (2) and guide rollers (3) is, the fibrous web (1) of at least one band (4) of the respective Drying group pressed against the outer surface of the drying cylinder (2) and the Fibrous web (1) at at least one transfer point (5) between two accompanying transfer elements (6,7) is transferred and the receiving one Transfer element (7) a higher speed than the transferring Has transfer element (6).

Ausgehend davon sollen bei sicherer Bahnführung größer Geschwindigkeitsdifferenzen dadurch möglich werden, dass die Transferelemente (6,7) an der Übergabestelle (5) mit Geschwindigkeitsdifferenz nicht gegeneinander gedrückt werden und einen Abstand von weniger als 70 mm aufweisen.

Figure 00000001
On the basis of this, greater speed differences should be possible with safe web guidance in that the transfer elements (6, 7) at the transfer point (5) are not pressed against one another with a speed difference and are at a distance of less than 70 mm.
