Machine Concepts offers a range of options and features that can be added to our levelers to further enhance the leveling process and maintenance operations. These options include innovative features like pull rolls for material tension control, intermediate rolls for handling surface-critical materials and chrome work rolls that prevent contamination.
A pull roll located after the leveler is used for several applications. One application is to assist driving material through the leveler when the work roll drive system is near maximum capacity. The pull roll can also be used to pull very light gauges through a pull-through leveler, therefore eliminating the work roll drive system entirely. The pull roll is used in conjunction with the patented AutoFlat® system to generate the tension zone for the shape sensors to read shape. The pull rolls are available with different roll coverings depending on the application, with either the lower or both rolls driven. The design uses a rigid assembly with an equalizer tube to maintain parallelism, and hydraulic controls allow for adjustable pinch pressure.
Intermediate rolls are available in 5 high and 6 high configurations and are used for surface critical materials to reduce witness striping from backup bearings.
Rolls can be spiral grooved or smooth depending on the customer’s needs.
The high-speed lift provides rapid open and close. This option is very beneficial for continuous operation of coil-to-coil lines to pass a stitch through with minimal unprocessed material.
Available on G3B Leveler only, the work roll removal cart is used with the G3B leveler to extract and install the work roll modules for cleaning and maintenance. The free-wheeling cart has a hydraulic lift function to line up with either upper or lower work rolls. A hand crank mechanism is used to extract/install the work roll module.
Available on the G3DC or G3CC cassette-style levelers, the cassette exchange system is used to swap cassettes in the leveler and store the unused cassette. The unit consists of a base frame with a two-position sliding storage rack. The rack traverse and cassette traverse are powered functions and are pushbutton controlled.

Available on the G3DC or G3CC cassette-style levelers, the lifting bale is used to lift the upper half of the cassette off the lower half when the cassette is out of the leveler. The base unit provides 180º of upper cassette rotation for cleaning and servicing upper work rolls and backup rails.
An entry pinch roll and/or peeler table can be mounted to any of our leveler types in order to locate the leveler directly after the uncoiler and eliminate the need for additional threading equipment. This is advantageous when space is at a premium.
S-Loops and U-Loops systems are generally located between the leveler and the feeding equipment in the line. These systems allow the leveler equipment to run continuously while allowing the feed equipment to start and stop as dictated by the downstream process. Our S-Loop and U-Loop systems can be integrated into the leveler control system in order to set a more consistent leveler speed and thus get flatter material.
