AI Technical Summary

Problems solved by technology

Additionally, machining tubular rolls and adjusting tubular roll balance is very time consuming
Despite the increased load capacity, the overall weight of the tubular roll increases due to the additional components and the inner cylinder
In addition, the number of parts is high, and it is difficult to fit the parts between the cylinders
Use of materials of varying thickness further complicates manufacturing

Embodiment Construction

[0024] Figure 1 is a cross-sectional view of a shell 10 of a tubular roll according to the invention. Tubular rolls are usually designed for paper machines, but they can also be used in board machines and other similar forming machines. The basic components of the tubular roll include a housing 10 and roll heads 11 at both ends of the housing for supporting the tubular roll so that it can rotate relative to the paper machine. One embodiment of the roller head 11 is shown in image 3 middle. In addition, as shown in FIG. 1 , the casing 10 has two metal cylinders 12 and 13 adapted to be coaxially arranged at a distance from each other. A core construction 14 is used to support the cylinders 12 and 13 , the core construction 14 is located between the cylinders 12 and 13 and connects the cylinders 12 and 13 .

[0025] According to the invention, at least the inner cylinder is ingeniously produced from sheet metal having a thickness of 1-5 mm, more preferably 2-4 mm. In tubular...

Abstract

The invention relates to a tube roll for a paper machine. The tube roll includes a shell (10) and roll heads (11) for supporting the tube roll rotably to a paper machine. The shell (10) has two metal cylinders (12, 13) adapted coaxially at an interval of each other. Between the cylinders (12, 13) there is additionally a core construction (14) attached to both of the cylinders (12, 13). Each roll head (11) is attached to both of the cylinders, of which at least the inner cylinder (13) is made of a sheet metal material. The invention also relates to a method for manufacturing a tube roll.

Description

technical field [0001] The present invention relates to a tube roll for a paper machine comprising: a housing and roll heads at both ends thereof for rotatably supporting the tube roll on the A paper machine; two metal cylinders in a housing, adapted to be arranged coaxially with each other at a distance; and a core formation between the cylinders, connected to the two cylinders. The invention also relates to a method of manufacturing a tubular roll. Background technique [0002] So-called tubular rolls are used in paper and board machines. A tubular roll has a hollow interior and its shell is tubular. Tubular rolls are mainly used in nipless positions due to their light weight and hollow construction compared to solid rolls. That is, the tubular rolls are separate and do not come into contact with another roll. This location includes, for example: paper rolls and guide rolls in calenders as well as press rolls. By having a tubular roll rotatably supported on the paper ...
