Problems solved by technology

[0012] A hitherto unconsidered problem is that although the material properties of the metal strip to be straightened are taken into account, sometimes satisfactory straightening results cannot be achieved due to strip thickness fluctuations
Especially the straightening of unrolled strip ends is more problematic because the strip heads or tails fluctuate greatly in thickness
The entire longitudinal axis of the strip exhibits wedge-shaped or even step-shaped thickness variations, so it is extremely difficult to achieve a repeatable straightening process

Embodiment Construction

[0029] Figure 1a and Figure 1b A side view of a metal strip 1 which is to be straightened is shown, showing the region of the head of an unrolled strip. Typically, the thickness d of the metal strip 1 is not constant over the entire longitudinal axis of the strip corresponding to the conveying direction R. Figure 1a In the case of , the metal strip 1 extends wedge-shaped, while Figure 1b It means that the thickness of the metal strip extends in steps.

[0030] Straightening of such metal strips is particularly difficult and only figure 2 Effective straightening is only possible with the straightener 2 shown.

[0031] The metal strip 1 is fed into the straightening machine 2 at a constant speed V in the conveying direction R. The straightening machine 2 is a roller straightening machine and has a plurality of straightening rollers 3 . Four lower straightening rollers 3 and three upper straightening rollers 3 are respectively arranged on a beam 15 and 16 which are relat...

Abstract

An improved medical treatment and medicine is provided to quickly and safely resolve HIV and other microbial infections. The inexpensive medicine can be self administered and maintained for the prescribed time. The attractive medicine comprises an antimicrobial concentrate comprising microbe inhibitors, phytochemicals or isolates. Desirably, the effective medicine comprises a surfactant and an aqueous carrier or solvent and a nutrient. In the preferred form, the medicine comprises: Echinacea and Commiphora myrrha phytochemicals, benzalkonium chloride, a sterile water solution, and folic acid.

Description

technical field [0001] The invention relates to a method of straightening a metal strip which is conveyed in the conveying direction through a straightening machine and thus straightened, in which the metal strip is passed over a plurality of straightening rollers in a The corrective force is applied in a direction perpendicular to the surface of the metal strip. Furthermore, the present invention relates to a straightening machine, wherein the thickness of the metal strip is measured before the metal strip enters the straightening machine, and the straightening roller is pressed down according to the measured thickness along the normal direction of the surface of the metal strip. A measurement is made at the exit side of the straightening machine to determine the arching tendency and deviation of the straightened metal strip from the ideal line in the normal direction of the metal strip surface, and according to the arching tendency And the deviation exerts a reduction on th...
