薄带材纵剪成窄带材以后,再卷取一向是较困难的,尤其是将宽而薄(0.2～1.5毫米厚)的软带材(如铝带)剪成多条窄带后再重卷就更加困难。主要存在以下四个问题。 1.由于被剪带材截面厚度不均匀,因此纵剪后各条窄带材的卷取速度不能一致。较厚的窄带材,重卷后的带卷直径增加得较快,卷取的线速度也就较大。因而各条窄带材的张力不等。宽带材往往是中间厚而边缘薄,所以纵剪后重卷时,中间窄带材的卷取张力较
After the strip is slitted into a narrow strip, it is more difficult to rewind it, especially when it is cut into a plurality of narrow strips with a wide and thin (0.2-1.5 mm thick) soft strip (such as aluminum strip) More difficult. The main existence of the following four questions. 1. As the cross-section of the cut strip thickness uneven, so after the slitting of the narrow strip material coiling speed can not be consistent. Thicker narrow strip material, rewind the coil diameter increases faster, the coiling line speed is larger. Therefore, the tension of each of the narrow strip varies. Broad band material is often the middle of thick and thin edges, so reeling after slitting, the middle of the narrow ribbon take-up tension than
