Abstract

PURPOSE:To achieve high yield work through low cost facility without damaging material, by winding metal slitting thread through correction roll means and take-in means. CONSTITUTION:Metal slitting thread 1 is fed out from a coil 10 wound over a reel 12 and wound sequentially through leveler 14, correction roller means 16 and take-in means 18 over a winder 20. Here, the correction roller means 16 is constituted with right/left correction rollers 24, 24' engagable with the opposite end faces similarly with the upper/lower correction rollers 22, 22' engagable with the upper/lower faces of metal slitting thread 1 to be corrected. The take-in means 18 will feed the metal slitting thread 1 continuously with constant tension and speed to a winder 20 as a constant tension constant speed control pinch roll. Consequently, high yield work can be achieved without damaging material through low cost facility.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for winding a metal slitting strip formed by cutting a metal strip with a sliver, and in particular, for example, for winding a coil of such a metal slitting strip to meet the required conditions. The present invention relates to a method for winding a metal slitting strip used for rewinding it into a long length.

As shown in Fig. 3, this type of metal slitting strip 1 generates ridges 1a on both edges during slitting, so these ridges are removed once in the slitting + IE process. Thereafter, the coil from which paris has been removed is re-wound to the length requested by the user in a separate process. In the prior art, this removal of paris was performed using an edger roll and a skin pass rolling mill. However, with this method, the equipment required to remove the paris is expensive, and when the coil is handled separately in the straightening process and rewinding process, and when the coil is passed through a roll, etc., scratches occur on the metal slitting strip. In addition, there was a problem that there was a problem that there was a problem between the skin pass rolling mill and the rewinding machine, resulting in a low yield.

An object of the present invention is to provide a method for winding a metal slitting strip that can be operated with inexpensive equipment and at a high sludge without causing damage to the material.

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a state in which the method according to the present invention is carried out. is stored in a pay-out reel 12, and as the coil rotates, a metal slitting strip 1 is paid out from this coil. This metal slitting strip l is a leveler 1
4. It passes through the correction roller means 16 and the take-up means 18 and is wound up by a winder (rewinder) 20.

As shown in FIG. 2, the correction roller means 16 includes upper and lower correction rollers 22, 22' that engage with one lower surface of the metal slitting strip l to be corrected, and left and right correction rollers 24 that engage with both end surfaces. , 24', and is generally called a Turk's head. These correction rollers 22, 22'.

24 and 24' may not be driven as shown, or may be driven. The metal slitting means 16 is thus formed by a straightening roller.
Since the entire outer surface of the material is constrained and molded, the burr during slitting as shown in FIG. 3 is removed. It is preferable that the distances between the correction rollers 22 and 22' and 24 and 24 degrees can be adjusted to correct a metal slitting line l having an arbitrary width.

The take-off means 18 is a pinch roll or a track-type take-off machine capable of controlling a constant tension and a constant speed, and feeds the metal slitting strip 1 to the winder 20 at a constant tension and speed.

In the above embodiment, one straightening roll means 16 is used, but two or more straightening roll means 16 may be used in tandem. Further, in the embodiment shown in FIG. 9, the coil 10 of the metal slit strip formed by cutting is wound, but the method of the present invention may be used when winding into a coil from the slitting process. .

According to the present invention, as described above, the straightening roll means for removing paris is simple, so the equipment is inexpensive, there are few parts of the device through which the material passes, and there are fewer scratches on the material, and the yield is reduced. There is a practical benefit in that high quality metal slitting strips can be obtained.
