The primary purpose of a slitting machine is to divide a wide parent roll or web into multiple narrower rolls, often referred to as slit rolls or slit coils. This process allows manufacturers to customise the width and length of the material to meet specific requirements for downstream operations or customer orders.
Slitting machine is a processing machine that longitudinally slits long rolls of thin paper and film into desired widths while simultaneously rewinding them into coils. It basically consists of an unwinding section, a conveying guide roller section, a cutter section, and a rewinding section. The most important aspects of a slitter are proper cutting conditions and balanced tension during unwinding and rewinding. By employing cutting methods and tension control tailored to the characteristics of each material, high-quality cut surfaces and rewound laminates can be achieved.
Slitting machines can cut various papers, films, and aluminum foils. There are many types of slitting machines, each with its own unique functions and performance.
It is divided into two parts: split with separate loading frame and connected. The unwinding diameter of the split part is 1000mm, the unwinding diameter of the connected part is 800mm, and the rewinding diameter is 600mm.
Available in standard and high-speed (high-speed with built-in unloading rack).
Standard speed: 200m/min; high-speed: 350m/min or above (for film).
Basic unwinding: 600m/min; rewinding: 400m/min.
Horizontal unwinding: at the back; vertical unwinding and rewinding: at the front.
Specialized in cutting tape paper, a set of slitting machines, core cutting machines, core threading machines, and small rewinding machines.
Cut narrow, 8mm, 10mm, 12mm, 15mm, backrest rewinding
High-speed 500m/min. Widths 1100mm, 1300mm, 1600mm.
The C-type is a high-speed rewinding of 600mm (slip shaft rewinding 600mm, shaftless unwinding 800mm, standard integrated, independent 1000mm). The A-type is a 1m rewind (standard air shaft unwinding, standard independent 1000mm).
Slitting machines are known for their efficiency and versatility and are often used to complete large quantities of slitting in a short period of time. The following are some of the main features of slitting machines:
• Equipped with high-precision guide mechanisms such as servo motors, they precisely control slitting dimensions, with tolerances down to the millimeter or even micron level, meeting the high dimensional accuracy requirements for applications such as labels and films.
• Some machines feature automatic tension control systems to prevent stretching and misalignment of the substrate due to uneven tension, ensuring smooth, burr-free slit edges.
• Capable of processing a wide variety of substrates, including plastic films (PE, PET, PVC), paper, nonwovens, metal foils, tapes, and more.
• Supports diverse slitting requirements, such as slitting wide rolls into narrow rolls (roll slitting) or cutting single sheets to length (sheet slitting).
• Utilizing a high-speed drive system, slitting speeds can reach tens to hundreds of meters per minute, making it suitable for high-volume production.
• Automated loading and unloading functions reduce manual intervention, shortening production cycles and lowering labor costs.
Slitting machines are used in a variety of industries for different applications. Here are some examples:
• Plastic Film Slitting: Slitting wide-width films such as PE (polyethylene), PET (polyethylene terephthalate), and PVC (polyvinyl chloride) into narrow rolls for use in food packaging bags, courier bags, and plastic wrap.
• Paper and Cardboard Slitting: Processing wide-width kraft paper, coated paper, and corrugated cardboard for use in carton processing, label backing, and packaging carton production.
• Printed Material Slitting: Slitting wide-width rolls of printed paper and film (such as printed label stock) into narrow rolls that meet label and sticker specifications for subsequent die-cutting and bag making.
• Self-Adhesive Material Slitting: Processing wide-width self-adhesive mother rolls, slitting them into rolls of varying widths for use in label printers, automatic labeling machines, and other equipment.
Slitting machines are used to slit food and beverage packaging such as boxes, bottle shrink sleeves and can labels.
Slitting offers a wide range of applications and high efficiency, meeting the slitting needs of a wide range of materials. Capable of slitting a wide range of substrates with high quality and inline post-press processing, slitting machines are widely used in industries such as packaging, labeling, textiles, food and beverage, and commercial slitting. With continued technological advancements, slitting machines are expected to become even more efficient and versatile, making them an increasingly popular choice in the slitting industry.
