    摘要: Web unwound from a supply roll is slit into a plurality of bands by a slitting unit comprising circular disc blades. The individual bands are subjected to tension by a brake roll assembly positioned before the take up roll to hold the individual bands taut with a predetermined braking force in such manner that different degrees of slippage relative to the brake roll and the individual bands are effected.

    摘要: Winding device for metal strips, in which the metal strip is braked between two rollers which are pressed against one another. One of the rollers has a larger angle of wrap for the metal strip of at least 75.degree. and the other roller has a smaller angle of wrap for the metal strip of 45.degree. at maximum. The one roller with the larger wrap includes material on its periphery having a coefficient of friction for the material which is at least 20% lower relative to the braked metal strip than the coefficient of friction of the peripheral material of the other roller with the smaller amount of wrap.
