FRP-made "Industrial Roll Core" *Proven track record with high-performance films and metal foils.
Lisholite thermosetting resin laminated tube
For improving production efficiency and reducing defects! Excellent mechanical strength, heat resistance, chemical resistance, and dimensional stability.
The "Industrial Winding Core" is a core made of thermosetting resin "FRP" reinforced with fibrous substrates such as paper and glass cloth. It features excellent mechanical strength, heat resistance, chemical resistance, and dimensional stability, contributing not only to increased production efficiency but also to the reduction of defects and waste. It is being showcased at the Converting Technology Comprehensive Exhibition. 【Features】 ■ Many applications with high-performance films and metal foils ■ Lighter than metal winding cores ■ Superior recovery from deflection compared to metal winding cores ■ Service life can be extended with proper maintenance ■ Custom options available *For more details, please refer to the catalog.

Detailed information
-
Image of a two-layer tube The inner layer uses "glass epoxy," which has excellent strength, while the outer layer uses "paper phenol," allowing for the creation of surfaces tailored to the winding materials while maintaining strength, thereby enhancing the functionality of the winding core.
-
Example of a two-layer pipe, Part 1. This type features a lightweight paper phenol for the inner layer and a durable glass epoxy for the outer layer.
-
Example of a two-layer pipe, part 2. This type features a strong glass epoxy for the inner layer and finely textured paper phenol for the outer layer.
-
Image of a double tube Large and small pipes with different diameters are integrated with a flange. The hollow structure allows for weight reduction of the winding core. It is also possible to easily increase the size of the winding core without changing the chuck size of the winding machine. Reinforcements are added with ribs at points where hanging belts or forklift clamps make contact.
-
Examples of double-tube manufacturing This is a lightweight winding core with a hollow structure. It can accommodate an increase in the size of the winding core without changing the chuck of the winding machine.
-
Type with a metal flange. It is a type where only the part that is grasped by the chuck is made of metal.
-
Painting example This is an example of painting applied to differentiate the core colors by variety.
-
Food Sanitation Law Compliant Product (Single Layer Tube) The paper-based phenolic resin laminated tube PR-1311 is compliant with the Food Sanitation Law. It can be safely used as a core for food packaging materials.
-
Type with rubber lining Reduces transfer of steps when winding ultra-thin film.
Line up（4）
| Model number | overview |
|---|---|
| Single-layer pipe | This type can be used as a winding core with thermosetting resin laminated pipes as they are. |
| Double-layer pipe | Depending on the winding material, you can enhance the functionality of the winding core with a sturdy inner layer and a delicate outer layer. |
| Double pipe | Pipes of different sizes and diameters are integrated with a flange. This allows for weight reduction of the pipe due to its hollow structure. It is also possible to increase the size of the winding core without changing the size of the chuck on the winding machine. |
| Pipe with rubber lining | This winding core has a rubber lining on the surface. When winding extremely thin films, it reduces the transfer of the initial step to subsequent layers. |
