A die-cut roll is a roll-shaped blade used to cut materials such as paper and non-woven fabric into arbitrary shapes. Since it cuts the material in a rotary manner, it allows for faster die-cutting compared to flat pressure methods (up and down), making it suitable for mass production. It is used not only for hygiene materials such as diapers, sanitary napkins, and masks, but also for food packaging and food die-cutting. <Features> - Enables speedy die-cutting - High durability - Can be re-sharpened

It is a cutting tool designed to make it "easy to open" PET and PE, which are usually difficult to cut with regular hands. A "perforated blade" refers to a cutting tool where the cutting part and the non-cutting part are arranged alternately. A typical example is a series of three katakana characters resembling the letter "ha." In packaging used for ointments, materials laminated with PE (polyethylene) and aluminum are often used. By adding perforations to the PE, which is the reason for its difficulty in cutting, after printing and then laminating, a pouch packaging is created that provides guidance during cutting, balancing ease of opening with barrier properties.

In the packaging industry, especially for label applications, there is a demand for both diversification in design and high-quality finishes. The shape and size of labels significantly influence the appeal of products and are crucial elements in enhancing brand image. However, traditional cutting methods have faced challenges in cutting complex shapes and mass production. Die-cut rolls are roll-shaped cutting dies used to cut materials such as paper, non-woven fabric, and film into any desired shape. Since they cut materials in a rotary manner, they are more suitable for high-speed and mass production compared to flatbed (up-and-down) methods. They excel in roundness and cylindricality and can accommodate half-cuts, which are difficult with up-and-down methods, by adjusting the gap with the receiving roll. 【Application Scenarios】 - Food labels - Cosmetic labels - Daily necessities labels - Other labels of various shapes 【Benefits of Implementation】 - Increased productivity through high-speed processing - Adaptability to diverse shapes - High-quality finishes - Enhanced brand image

▶Surface Treatment - Laser Hardening Laser irradiation is applied only to the cutting edge, achieving a hardness of HRC65 through partial quenching. This is suitable for operations like full cuts where the cutting edge is prone to damage. - F-Coat (Non-Stick Treatment) Tujikawa's unique non-stick coating, "F Coat," reduces the adhesion of ink and glue. Additionally, due to its very thin coating, it does not affect the blade height. - DLC Coating By applying a DLC coating with very high hardness and wear resistance, it contributes to longer tool life. The film thickness is about a few microns. ▶Flexible Die Mounting Base The base, which has been processed for parallelism, is ideal for use in combination with high-precision sharpening dies. We can accommodate various requests such as waste removal holes created by wire processing and positioning pin machining. Designs considering attachment to press machines are also possible. Please feel free to consult us for other special processing needs.

This is for trial production before considering the production of die-cut rolls and can be used for projects with smaller lots than die-cut rolls. ▶ High Hardness The typical material is die steel (HRC 58-60), but it is also possible to create it with even harder high-speed steel (HRC 63). ▶ High Precision It can achieve the same precision as sharpening blades (dimensional tolerance ±0.05). ▶ Regrinding Repairable Even if the blade edge wears out, it can be re-sharpened by our company. ▶ One-Stop Production System We handle not only the blades but also the incorporation of receiving jigs and heaters. ▶ 3D Shape Compatibility We can accommodate height differences and three-dimensional cutting of curved surfaces for molded base materials, insert films, etc.

A segment type that is easy to replace is often used for cutting various sizes. Since repairs can be done on individual segments, costs can be reduced compared to regular rolls. We also manufacture corrosion blades that are attached to magnetic cylinders or used with clamps.

▶ Anvil Roll It is a flat roll with nothing on the roll body. The surface is polished with fine grinding stones to increase surface roughness. It is finished as an anvil roll that can receive the optimal condition without small unevenness when cutting with a die-cut roll or embossing with an embossing roll. ▶ Suction Anvil Roll This roll has many small holes on the surface of the roll body. By sucking in or blowing out air through these small holes, it prevents the cut products or waste from scattering and allows for the suction of debris. ▶ Pocket Anvil Roll This roll has recessed areas on the roll body. It is an anvil roll used for cutting or embossing thicker products. The recesses are created to prevent the product surface from rubbing during cutting or embossing.
