Embodiment Construction

[0011] figure 1 An endless metal belt 1 circulating around a plurality of guide rollers 2 is shown in . Inside the belt loop there is a transverse support member, such as a beam 3, along which a movable repair support 4 is arranged. The repair support is preferably made of a non-solderable material such as copper or aluminium, but it can also be made of a weldable material which is preferably provided with a non-solderable protective layer on its surface facing the metal strip. The protective layer can be formed, for example, from a film or sheet metal, or it can be designed as a coating. The control of the metal strip 1 is arranged such that the part of the metal strip to be repaired is automatically or manually guided to or remains at the position of the transverse support member 3 in the forward direction of the metal strip. The repair support 4 is then moved along said transverse support member 3 to the position of the part of the metal strip to be repaired so that the m...

Abstract

The invention relates to a device for maintenance of the metal belt. The metal belt (1) is taken as an endless belt surrounding a control member (2) to set up in the paper / board making machine or post processor. The device is provided with a transverse supporting element (3), the transverse supporting element (3) is located inside the belt rotating unit, and the position of the metal belt required to repair can move to a location of the transverse supporting element, the device is also provided with a repair supporting unit (4) which is movable along the transverse supporting element (3) to the repair need location of the metal belt for supporting the metal belt against the repair supporting unit to implement necessary repairing measures outside the belt rotating unit.

Description

technical field [0001] The invention relates to a device for servicing a metal belt installed as an endless belt running around a control member in a paper or board machine or in a finishing machine. Such endless steel belts are used, for example, in metal belt calenders and Conde Belt (condensation belt) belt dryers. Such a fibrous web processing device equipped with a metal belt circuit can also be a web pressing device, a dryer, a coating device, a sizing device, a pressing device and / or a cooling device. Background technique [0002] In operation, the metal strip is subjected to fatigue loads as well as corrosion loads. In addition, strong load forces (beanspuchende Kraft) act on the metal strip due to fatigue cracks starting to appear on the metal strip. Various bumps may also appear on the strap. These cracks and bumps can be repaired by welding or hammering. Often a metal strip is used in operation wherein the metal strip is heated between heatable guide rolls in ...
