AI Technical Summary

Problems solved by technology

This variation is unacceptable as the resulting coils may be too susceptible to damage as they continue to be conveyed
The main cause of this winding error is the unevenness of the steel strip, which can lead to a strip direction transverse to the conveying direction in the coiling device during winding

Embodiment Construction

[0026] exist figure 1 and 2 The coiling device 1 shown in FIG. 2 consists of a drive 2 to which a coiling shaft 3 is connected, which has a coiling mandrel 4 arranged at its end. The upper and lower drive rollers 6 , 7 are supported in the drive frame 5 and the pivotable strip tension measuring device 10 is supported on the deflection axis 8 with its point of rotation 9 immediately behind the lower drive roller 7 . The strip tension measuring device 10 is connected to the winding mandrel 4 with a guide table 11 which, with the section leading up to the lower drive roller 7 , also covers the free space there facing the strip tension measuring device 10 .

[0027] The metal strip 13, which is moved in from the processing line, not shown, via the roller table 12 and conveyed by the drive rollers 6, 7 through the drive gap formed by them, is wound up by means of the guide table 11

Abstract

Method for winding metal strip (13) on to a spindle (4) to form a reel uses a swiveling tension sensor (10) to measure the tension of the strip during winding. This is pivoted on the reel frame (5). An independent claim is included for a machine for carrying out the method, in which the tension sensor comprise a lever (10a) pivoted on the frame and a second lever (10b) pivoted on its free end carrying a roller (23) which can contact the strip. A pressure sensor (24) is mounted between the two levers.

Description

technical field [0001] The invention relates to a method and a device for winding a metal strip on a winding mandrel arranged inside a coiling shaft, so that the metal strip is guided by a drive with lower and upper drive rollers in a drive frame On the winding mandrel, a platform is provided below the metal strip for guidance and a steel strip adapter is arranged above the metal strip as well as a rotatable manhole cover for connecting the metal strip to the winding mandrel. Background technique [0002] A transmission or transmission known from DE 19520709 A1 has a stationary lower roller and an upper roller which is adjustable relative to the lower roller. The adjustable upper roller is supported in a pivoting frame adjusted by means of a pressure cylinder, which consists of two opposite rocker arms, which are supported at their common axis of rotation via a base part supported at both ends in the transmission frame connect. The rocker arms of this transmission can each...
