Abstract

Es wird eine Maschine zur Herstellung einer Materialbahn, insbesondere Papier- oder Kartonbahn, mit einer Trockenpartie (1), die mindestens eine zweireihige Trockengruppe (3) aufweist, die eine obere und eine untere Reihe von beheizbaren Trockenzylindern (5-15) umfaßt, denen jeweils ein Transportband (17,25) zugeordnet ist, das die Trockenzylinder einer Reihe (5,7,9) und den Trockenzylindern zugeordnete Umlenkwalzen (19,21,23) mäanderförmig umläuft, wobei die Materialbahn (31) abwechselnd um einen Trockenzylinder (5,7,9) der oberen Reihe und um einen Trockenzylinder (11,13,15) der unteren Reihe und zwischen den Trockenzylinderreihen in einem freien Zug geführt wird, und mit mindestens einer der Überführung eines Einfädelstreifens dienenden ersten Düseneinrichtung (37,39), deren Gasstrom im wesentlichen entgegen der Laufrichtung der Materialbahn (31) verläuft, vorgeschlagen. Die Maschine zeichnet sich durch eine auf der der ersten Düseneinrichtung (37;37') gegenüberliegenden Materialbahnseite angeordnete Führungseinrichtung (45) aus, die mindestens eine zweite Düseneinrichtung (47,49) umfaßt, deren Gasstrom (51) im wesentlichen in Laufrichtung der Materialbahn (31) verläuft.

It is a machine for producing a material web, in particular paper or cardboard web, with a dryer section (1) which has at least one two-row dryer group (3) which comprises an upper and a lower row of heatable drying cylinders (5-15), which A conveyor belt (17,25) is assigned to each, which meanders around the drying cylinders of a row (5,7,9) and deflection rollers (19,21,23) assigned to the drying cylinders, the material web (31) alternatingly around a drying cylinder (5 , 7,9) of the top row and around a drying cylinder (11, 13, 15) of the bottom row and between the rows of drying cylinders in a free pass, and with at least one first nozzle device (37, 39) serving to transfer a threading strip, the gas flow of which runs essentially counter to the running direction of the material web (31). The machine is characterized by a guide device (45) which is arranged on the material web side opposite the first nozzle device (37; 37 ') and which comprises at least one second nozzle device (47, 49), the gas flow (51) of which essentially extends in the running direction of the material web ( 31) runs.
