The Guidolin Girotto rotary die cutting system, model RO 250, is the preferred rotary converting platform by the most prominent converters of 3M, Tesa, Avery Dennison, Lohmann, Nitto Denko and Scapa double sided adhesive tapes, technical adhesive tapes, foam tapes and similar adhesive products. Guidolin Girotto is a worldwide distinction sign in the technical die cutting sector with more than 20 years’ experience in die-cutting equipment manufacturing.
The RO 250 high speed rotary die cutting machine has a useful working width of 250mm and is available in three body lengths; 1.7M, 2.2M and 3.05M with production speeds ranging from 0-100 meters per minute. Our rotary machine is suitable for kiss cutting and total cutting and can be used with flexible magnetic tooling or hardened rotary tooling and designed to accommodate the customer’s existing cutting dies. The rigid electro-welded steel frame, modular stations with a variety of web-pass configurations, and computer controlled system make the RO 250 rotary die cutter versatile, fast & simple to operate; assuring rapid transition from job-to-job which decreases machine downtime, reduces labor and overall manufacturing costs.
Due to the modular design with every station moveable, the machine can be set-up to run a wide variety of jobs in a given shift, making the RO 250 the logical solution for numerous applications. The Guidolin rotary die cutting machine is equipped with a single brushless servo motor and coupled with an in-line drive shaft and precision worm gears in order to grant the same torque strength from zero to maximum working speed. In addition, unique to the Guidolin product, the machine can operate in both start/stop mode & continuous mode; in start/stop mode, the rotation of the tool, pneumatic expulsion unit or transversal guillotine occurs according to the desired quote set in the Touch-screen controller.
Furthermore, all the transports and lamination stations are equipped with a single hand wheel adjustment knob for fast set-up (nip rolls are perfectly parallel with the web), eliminating the “walking” of web, commonly associated with dual adjustable transports. A standard 7” color touchscreen stores up to 500 different recipes, and records production output based on parts cut or length of the material converted.
Our team of engineers reviews your application and requirements, listen to your needs, and respond to offer a more innovative die cutting & converting solution to improve your current manufacturing process. Each machine is designed after a careful evaluation of the customer needs, the challenges of the material to be converted, therefore every machine produced is “made to order” for each client.

Wide Range of Die Cutting Capabilities
Mechanical Die Cutting : Our mechanical rotary die stations can be configured for multiple size tools, both in width and diameter, and custom stations can be designed to accept pre-existing tooling. Micrometrical adjustment both transversally and longitudinally allow for precise positioning of the tool based on web location. Reverse die cut stations are also available to cut material from the bottom – commonly used for creating a pull tab on adhesive and double sided adhesive materials.
Servo Motor Controlled Die Cutting : The precision of registration or re-registration on each die cut is based on our control system coupled with a servo motor at each station. The die cut modules can be adjusted independently of each other, allowing the cut to be changed on the fly making precise cuts even for inconsistent fiducial registration marks. Individual servo control at each module allows for precise tension control and a different speed ratio can be set at each station – an important factor in narrow wen converting. Fiber optical photocells and sensors are used to register printed materials, printed references or pre-die cut components obtaining the required speed to register each part allowing continual feedback.
“Flying Knife” Sheeting & Perforation : The “flying knife” servo controlled sheeting & perforation unit rotates the tool faster in order to cut in the right position. In most cases, the tool is one transversal blade and it is used as a guillotine for transversal kiss cutting, total cutting or perforated cutting. Our “flying knife” module is different than a semi-rotary die cut station because normally our rotary machines are used to cut materials thicker than label stock, laminated adhesives where the liner has been changed prior to arriving at the die-cutting station.
Laser Die Cutting : Laser Die Cutting offers innovative and cost-effective solutions for processing simple and complex geometries without the use of traditional hard tooling – superior part quality that cannot be replicated in the traditional die cutting process. This technology increases design flexibility, is cost efficient with high quality through-put, minimizes material waste with very low maintenance. Laser Technology is the ideal dieless cutting solution for just-in-time manufacturing & short-medium runs and is well suited for converting high accuracy components from flexible materials including label stock & PSA, double sided adhesives, gaskets, plastics, textiles, difficult abrasive materials & even aggressive adhesive materials like VHB that typically adhere to the cutting blade.
High structural quality, accurate die cutting precision, silence, versatility and excellent relation between quality and price are the best representation of our rotary die cutting machines in the world.
