Embodiment Construction

[0020] The figures show different embodiments of a device for smoothing a metal strip 1 , in particular a thin metal strip made of an aluminum alloy. This device has at least one tensioning roller set 2 configured as an inlet tensioning roller set and at least one tensioning roller set 3 configured as an exit tensioning roller set, wherein the inlet tensioning roller set 2 serves to build up the tension and the exit tensioning roller set 3 Tight roll group 3 is used for removing tension. Between the inlet tension roll set 2 and the exit tension roll set 3 , a strip processing device, for example a rolling stand 4 ( FIGS. 1 to 4 ) and / or a stretching unit 5 ( FIG. 5 ) can be arranged. The stretching unit 5 of FIG. 5 has a further set of tensioning rollers 6 configured as a set of stretching rollers.

[0021] According to the invention it is now provided that at least one tensioning roller 7 , 8 of at least one tensioning roller set 2 , 3 , 6 is pivotable in and / or transversely...

Abstract

Sets of tightening rollers form a feeder set (2) of tightening rollers and a delivery set (3) of tightening rollers. The feeder set of tightening rollers increases pulling action. The delivery set of tightening rollers decreases pulling action. Between the feeder set of tightening rollers and the delivery set of tightening rollers there can be a band-treatment device, e.g. rollers (4) / stretching devices. An independent claim is also included for a method for planishing / smoothing metal bands during rolling, aligning and / or stretching.

Description

technical field [0001] The invention relates to a device and a method for smoothing metal strips, in particular thin metal strips, during rolling, straightening and / or stretching. Such a device has at least one tensioning roller set with at least two tensioning rollers. Within the scope of the present invention, a thin strip refers in particular to a metal strip having a thickness of 0.05 mm to 1 mm, preferably 0.1 mm to 0.5 mm. Metal strips are in particular aluminum alloy strips. Background technique [0002] According to today's standards, metal strips, especially thin metal strips, have to meet increasingly high requirements for strip flatness and at the same time require extremely high strip surface quality. Among them are various methods for smoothing metal strips, such as rolling (in particular temper rolling), straightening (in particular stretch bending straightening) and drawing (Zugrecken). The devices used for this usually have an inlet tension roller set for ...
