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.

Brake roll for spanning several bands

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.
