Embodiment Construction

[0040] exist figure 1 , the strip 1 is fed to the winding device from the right. In the case of the strip material being foil, it may be conveyed from a rolling process. The strip 2 is guided on its way to the reel 1 through a double wrap angle deflection roller arrangement comprising a shapemeter roller 3 and a pinch roller 4 , the shapemeter roller 3 being located upstream of the pinch roller 4 . Firstly, the strip 2 is guided to pass through the shaper roll 3, and the arc of the strip covered on the shaper roll 3 is a small wrap angle α 1 . The strip arc α covering the shapemeter roll 3 is the angle between the plane of the incoming strip 2 and the plane of the strip 2 after it leaves the shapemeter roll 3 . The wrap angle is determined by the position of the pressure roller 4 . exist figure 1 , the pressure roller 4 is in the so-called small wrap angle position. After leaving the pinch roller 4, the strip reaches the reel 1, which is fastened on a driven winder unit ...

Abstract

Apparatus for coiling a strip-shaped material with at least one ironing roll (10) which is carried by at least one pivoted lever (11) of constant length that is pivotable about the swivel axis of an adjustable pivot point, and with a deflection roller device for monitoring the strip-shaped material's shape which comprises a shape meter roll (3) and a tucking roll (4), the tucking roll (4) being atleast vertically adjustable and fixable in at least two tucking roll positions. The adjustable pivot point is fixable in at least two pivot point positions, which are positioned in such a way that for each tucking roll position there exists a pivot point position in which, throughout coiling, the distance between the ironing roll's contact point with the coil and the strip-shaped material's tangent point onto the coil (7) is maintained at the optimum working distance within a tolerance of +-5 mm.

Description

technical field [0001] The present invention relates to a method and an apparatus for winding a strip-shaped material, preferably a metal foil. Background technique [0002] When winding strip-shaped material (e.g. metal foil after a rolling process) on a winding device having a horizontal winder unit receiving a reel, air tends to become trapped between overlapping winding turns of the reel, This leads to problems like coiled weaves, towers, low density, breakage and lateral fluctuations. In order to avoid these problems, which would render the reel completely unusable, flattening rollers are usually employed, which compress the strip-shaped material on the reel. The flattening rollers are located downstream of the point of tangency at which the strip material enters the reel. During the gradual formation of the reel, due to the increase of the diameter of the reel, the position of the tangent point will change, and these different positions passed through form the tangen...
