The strip is fed to the shears with an accuracy of + / - 1 mm. Due to the high strip back-tension, the circular knives operate at optimal speeds. The best cutting quality is achieved when the strip to be cut is under tension.

Only the Umlauf Bridle technology provides the possibility of leveling all strips of slit coils at the same time. All the strips of a slit coil are leveled with the same specific back-tension, i.e. shorter strips will be stretched. Thanks to the unique way of applying back-tension to the strip, leveling with Umlauf Bridles is as if each strip of a slit coil was running separately through a leveler.

Each strip of a slit coil is subjected to the same specific back-tension. The elastic coating of the chain cars compensates the differences in speed between the individual strips. Every strip is wound into straight-edged slit-strip coils of the same specific tightness.

Easy and quick threading No changing of felt Long intervals between replacement of the crawler tracks’ elastic coating

Up to ten times longer service life of the slitting knives
