Embodiment Construction

[0020] A knife 1 or similar stripping or scraping implement, not shown, movable along the edge of the metal strip is secured to a support arm 2, preferably screwed to the support arm and can be removed and replaced. The support arm 2 to which the cutter is attached is mounted on a movable support 4, oscillating in the plane of the metal strip about an axis 3 substantially perpendicular to the axis of the metal strip. The support 4 is mounted to a central support around a second axis 5 substantially parallel to the axis 3, the support structure being explained further below.

[0021] The spacer rollers 6 are preferably mounted rotatable around the axis 3 of the support arm 2, moving along the edge of the metal strip as it moves through the entire device, thus ensuring that the distance from the axis 3 to the edge of the metal strip always remains constant, ensuring that the support arm 2 The distance from the edge of the metal strip is constant regardless of changes in the widt...

Abstract

A device for removing dendrites on the edges of a metal strip comprises guide devices for the strip, at least one mechanical stripping device, and a regulating device for re-adjusting this stripping device at least at one of the edges of the strip. In order to allow the best possible removal of dendrites at the strip edges, while providing optimum protection against damage to the strip and / or stripping device, at least one mechanical stripping device (1) is secured to a support (2) with flexible pre-stressing towards the strip edge, wherein the support (2) is coupled rigidly with the axle (3) of a spacer roll (6) running along the edge of the strip.

Description

technical field [0001] The invention relates to a device for removing dendrites at the edge of a metal strip, comprising a metal strip guiding mechanism, at least one mechanical stripping mechanism and an adjustment mechanism capable of adjusting the stripping mechanism at the edge of at least one metal strip. Background technique [0002] During the electrolytic treatment of the metal strip, crystals, so-called dendrites, are precipitated at the edges of the metal strip under the effect of the electric field strength ratio. This presents a processing problem for the metal strip in that the dendrites break and leave marks on the surface of the metal strip. To solve this problem, many attempts have been made to eliminate dendrites immediately after the dendrite-forming electrolytic treatment, especially at the edge of the metal strip. For this purpose, various implements have been proposed to remove dendrites mechanically, such as knives, brushes, or similar implements, but ...
