Leading China Paper Converter Equipment
Paper converter equipment, also known as a slitter rewinder, is a machine that is designed to convert large rolls of paper or other materials into smaller rolls. The process involves cutting the material into the desired size and then rewinding it onto a new core.
Slitter rewinders are commonly used in industries such as packaging, printing, and converting. They can handle a wide range of materials, including thermal paper, kraft paper,plastic films, and metal foils. The machine can be configured to cut the material to a specific width, length, or shape, depending on the application.
Jota Machinery is a company with over 10 years of experience in the paper converter equipment industry. Our slitting machines are known for the high quality and reliability.

An Introduction to Air Expanding Shaft for Paper Converting
Air expanding shaft, also known as air shafts, are commonly used in the paper converting industry to hold and control paper rolls during processing.
These shafts offer a reliable and cost-effective alternative to traditional shafts, making them a popular choice for manufacturers.
In this article, we will discuss the working principle, types, and benefits of air expanding shafts.
Air expanding shafts come in various sizes, but the most used ones are 3-inch (76mm) and 6-inch (152mm), with custom lengths available.
The inner diameter of the paper core is typically 76mm, but the air shaft is 74.2mm due to the expanding space. This ensures that the paper roll is held firmly in place during processing.
The working principle of air expanding shafts is simple.
When the air bag is filled with compressed air, it inflates and expands, pushing the lugs outwards.
The lugs are the components that hold the paper core in place. Once the core is locked into the shaft, the paper roll can be mounted onto the machine for further processing.
Air expanding shafts are easy to use, as the air can be released from the valve, and the paper roll can be easily removed from the shaft.
Air expanding shafts come in different types, including fully expandable, mechanical expanding type, leaf type, and strip type air shafts.
Each type has its advantages and is suitable for different applications.
- Fully expandable air shafts are flexible and can expand uniformly over their entire length, making them ideal for uneven rolls or when the core size varies.
- Mechanical expanding type air shafts have a precise expansion mechanism and can hold heavy loads without slipping.
- Leaf type air shafts are easy to install and use and are ideal for high-speed applications. Strip type air shafts are durable and require minimal maintenance.
Jota Machinery also offers a lightweight carbon fiber air expanding shaft for huge frame slitting machines, such as two-drum center surface slitter rewinders, frame type slitting machines, or 2100mm web width slitting machines.
These carbon fiber air shafts are lightweight and durable, making them ideal for high-speed and heavy-load applications.
In addition, Jota Machinery also provides water-cooling differential friction shafts for rewinding thin or uneven materials.
These shafts are designed to handle delicate materials that require extra care during the rewinding process. They come in sizes ranging from 3 to 12 inches.
In conclusion, air expanding shafts are an efficient and cost-effective solution for paper converting applications.
They offer a reliable and secure method of holding paper rolls during the conversion process, and their ease of use makes them a popular choice among manufacturers.
Whether for small or large-scale production, air expanding shafts can help increase productivity and streamline the paper converting process.
The red warning line on a thermal paper roll is a heat-sensitive indicator that appears on the paper when it is close to running out.
This line is designed to alert users that the paper roll is almost finished and needs to be replaced soon.
If the paper runs out completely, it can cause damage to the printer’s thermal head, which can be expensive to repair.
Therefore, it is important to pay attention to the red warning line and replace the paper roll promptly to avoid any potential damage.
A cash register till roll is a type of paper roll used in point-of-sale (POS) systems to print receipts for customers.
These rolls are made of thermal paper, which is coated with a heat-sensitive material that reacts to the thermal printing process.
When the POS system prints a receipt, the print head heats up and selectively activates the coating on the paper to create text, numbers, and graphics.
Cash register till rolls come in various sizes and lengths, and are commonly used in retail stores, restaurants, and other businesses that handle transactions with customers.
They are essential for keeping track of sales and providing customers with proof of purchase.
A thermal paper slitting machine is a type of industrial equipment used for cutting large rolls of thermal paper into smaller, more manageable sizes.
The machine operates by unwinding the thermal paper roll and feeding it through a series of blades that make precise cuts according to the desired width and length.
Thermal paper slitting machines are widely used in the production of thermal paper rolls for various applications, including cash register receipts, shipping labels, and event tickets.
They are capable of producing large quantities of thermal paper rolls with high accuracy and efficiency, making them an essential part of the manufacturing process for many businesses.
Jota Machinery provides full service for each client. We not only provide the paper slitting machine but also source you the raw material.
Our slitting machines all have the essential export certification.
