• Max. web width 550 mm
• Format length up to 1016 mm (40“)
• Max. process speed 50 cycl./min (max. mechanical speed 80 m/min)
• Format variability 200 mm (8")
• Magnetic cylinder with flexible die plates
• Magnetic cylinder with flexible creasing plates
• To manufacture folding cartons and inmould labels, to process printed cardboard with a grammage of up to 450 g/m² and foil with a min. caliper of 0.055 mm 
   

By using high-precision magnetic cylinders equipped with high-energy magnets, the rotary die cutting machine ensures proven rotary creasing technology. The magnetic cylinders are installed in high-performance creasing modules and are equipped with::

• Mechanical pressure load system with threaded spindles
• High-precision bearing assemblies and housings
• Central activated quick magnetic/anvil disengagement (without loss of registration)
• Cross adjustment of upper magnetic cylinder
• Format gears with circumferential register adjustment
• Use of positive and negative creasing plates mounted on both magnetic cylinders

The modern rotary die cutting machine is characterized by the use of high-precision magnetic cylinders with high-energy magnets installed in high-performance die cutting modules. This proven technology has been successfully used for years to convert IML labels.

The equipment of the high-performance die cutting modules includes:

• Pre-set and calibrated cutting pressure
• High-precision bearing assemblies and housings
• Central activated quick magnetic/anvil disengagement (without loss of registration)
• Micrometric die wear compensation (GCS)
• Anvil cylinder hardened and ground 
   

Ultra-modern print mark sensor with TwinEye technology ensures reliable detection of a printed mark on the printed material. The print mark control system consists of automatic initial registration, print mark detection and register precise positioning of the material. By reading the printed mark, the motion control system calculates a motion profile which determines the re-registering movement of the printed web to the tools.

The revolutionary drive technology (VARICUT) is characterized by the fact that continuous and intermittent processes are combined during the cutting process. The entire cutting process takes place in an in-setting process, always in register with the print. Thus a multitude of printing formats can be covered with one set of tools.

The RSM machines have a full width vacuum conveyor with multiple vacuum chambers for better product handling, no setting is required when changing product design/die cut pattern as well as material grammage.

By using robotization and automation, the product handling is absolutely safe and efficient. The automated delivery is designed in such a way that different products with the same print image can be stacked.
 

• Possibility to stack different types of products combined within the same printing image
• In heavily nested configuration or combining very large/long and small products in order to maximize the use of materials
• With continuous web speed of up to 50 m/min
• Specific pick & place plates
• Universal fast interchangeable pick-up plates take up products at synchronized high speed and stack them non-stop into a dual piling cassette system.

The in-feed station and the creasing modules are mounted on an electrically driven and linearly guided platform, which ensures efficient and correct format adjustment in web direction.

Save material, reduce costs: Automatic re-registration during reel changes saves material in the production process. It also significantly reduces the setup time for the rotary die cutting machine.

The electrostatic problems are reliably eliminated due to the specific use of discharge electrodes regardless of material and process speed.

The decurler in front of the in-feed station ensures the flatness of the blank and automatically and proportionally increases the decurling effect during unwinding, so that the material is perfectly decurled during the finishing process.
