AI Technical Summary

Problems solved by technology

After the press section, the strength of the web is relatively low due to the high moisture content of the web
As a result, problems such as web pull occur during transfer

Embodiment Construction

[0050] The principles of the invention will be described by reference to Figure 1 to Figure 8 The illustrated embodiment is described.

[0051] Paper and board machines comprise, inter alia: a press section for dewatering the web, and a dryer section. The dewatered web after traveling through the press section is conveyed to a dryer section for drying the web and thereby increasing its strength. In the figures, the press section is placed on the left and generally indicated by the reference number 1 , while the drying section is placed on the right and is generally indicated by the reference number 3 . Throughout the specification, the same reference numerals are used to denote identical or functionally identical components. The positions of the various components will be described relative to the running direction of the closed loop of metal strip, which is generally clockwise in the drawings.

[0052] refer to figure 1 , the press section of the paper and board machine...

Abstract

Disclosed is a belt assembly for moving a web from a press section of a paper- or board making machine to a dryer section of the machine comprises a combination of at least two of a first press roll (11) adapted to be arranged at the press section, a first dryer cylinder (31) adapted to be arranged at the dryer section, and a stretcher / guiding roll (51), which is arranged between or within the press section and / or the dryer section. A heat conductive metal belt that forms an endless loop and that is impervious to fluids goes over the first press roll and / or the first dryer cylinder and / or the stretcher / guiding roll in order to take over a web at the press section and to move the web to the dryer section.

Description

technical field [0001] The invention relates to a belt assembly for transferring a web from a press section to a dryer section and to an arrangement for a paper or board machine comprising said belt assembly. Background technique [0002] When producing continuous webs, such as paper or board, machines comprising multiple rolls (eg press rolls, dryer cylinders, suction rolls, etc.) are used. For moving the web from one machine section to a subsequent machine section, transport means such as screens, wires or felts in combination with the above-mentioned rolls can be used. Especially when transferring the web from the press section to the dryer section various problems such as web draw or web sticking can arise. [0003] According to the existing technology, such as Figure 9 As shown, the web is conveyed from an intermediate roll 101 to an adjacent suction roll 103 located inside a fabric or wire loop 105 . There is a gap of up to 100 mm between the intermediate roll 101 a...
