The centerpiece of the cross-cut shearing line is the precision leveler. The machine operates with hydraulic and position-controlled adjustment systems under load. In particular, the individual adjustments of the bottom leveling rolls help to reduce the inherent stresses in the material.  

Presetting and bending system 

Other highlights of the precision leveler include automatic presetting and the bending compensation system, which ensures a uniform roll gap over the entire width.  

Servo systems 

The leveler settings are achieved by the perfectly coordinated interaction of the main adjustment cylinders, bending compensation system, and individual roll adjustment of the bottom leveling rolls. The initial overstretching and the optimized plastification eliminate "old" inherent stresses and thus create the ideal conditions for the further processing steps for the strip products. 

Multi-roller cassette design 

The leveling roll cassettes enable the leveling rolls to be changed automatically in less than 20 minutes. They are each pre-configured with different roll diameters each and designed to level high-strength steels. 

The entry section with the payoff reel ensures safe and reliable charging of the cross cut shearing line. Special features include the variable pressure roller configurations, especially for high-strength strips, and the double pinch roll for improved uncoiling tension. Gentle uncoiling is ensured by a multifunctional processor roll and the automatic entry control system with separate sequences.

Depending on the customer's requirements, there are two pre-levelers to choose from:  

• For thick strip with a thickness of up to 25.4 mm  

• For thinner strip with a thickness of up to 12.7 mm 

The rotary side trimming shear trims the strip edges and cuts the strip to the desired width with a high degree of precision. Here too, two solutions are available to meet customer's individual requirements: Trimming shear for thick strips of up to 25.4 mm thickness or for thin strips up to 12.7 mm thick. The trimming shear is equipped with a scrap chopper, which cuts the side trimmings into small pieces. 

The flying shear is characterized by its reliable and proven cutting technology. To avoid deformation caused by the cut, particularly in the case of thin strip, the top knife and the bottom knife move toward each other when cutting. The automatic adjustment of the knife gap ensures a high level of cutting quality. The uniform cutting geometry achieves precise results with every cut. 

The system, which can be adjusted to the desired strip dimensions and package parameters, automatically performs all stacking processes. Moreover, a variety of optional equipment is available, including brush rollers, vacuum cleaners, or electromagnetic solutions. 

A cross cut shearing line from a single source – and SMS group supplies all the ancillary facilities required for it. These include, among other things, marking equipment, automatic weighing machines and strapping stations, ultrasonic and flatness measuring stations as well as cross-transfer units.

Stability, simple maintenance, uncomplicated adaptation to new conditions, and high-tech solutions – these are the requirements that modern automation systems must satisfy. Our X-Pact^® systems have a completely modular structure. They cover the full process chain, from power distribution and drive systems to measuring systems and sensors, and finally to the basic and process automation, including HMI systems. Our customers benefit from optimized productivity and yield, the highest quality, and excellent operability.
