The hydraulic unwind stand is a critical component of a high-speed roll paper sheeter. It directly affects cutting precision, operational efficiency, and overall production benefits. A well-designed hydraulic paper stand enhances the machine's stability, accuracy, and ease of use, making it an essential feature in selecting a cost-effective paper roll sheeter.
This article will explain in-depth what defines a high-quality and standard hydraulic paper stand and why it is crucial for maximizing efficiency in paper cutting and processing.
1. Structure of the Hydraulic Paper Stand

A hydraulic paper stand consists of several key components, including:
Clamp arms
Main shaft
Hydraulic cylinders
Hydraulic station
Control electrical cabinet
Brake system
Each part plays a significant role in ensuring the smooth unwinding and stable positioning of jumbo paper rolls.
2. Working Principle of the Hydraulic Paper Stand
The hydraulic paper stand operates through an independent hydraulic system that powers a shaftless dual-arm paper roll stand.
Here's how it works:
The hydraulic station generates oil pressure, which is transmitted through hydraulic pipes.
This pressure moves the piston rod within the hydraulic cylinder.
The movement of the piston rod allows the clamp arms to secure, lift, and position the paper roll on the main shaft.
This mechanism ensures precise control, stable operation, and smooth unwinding of jumbo rolls, reducing material waste and improving cutting accuracy in paper roll sheeting machines.
3. Key Features and Advantages
A. Secure Clamping & Customization Options
The hydraulic paper stand can firmly clamp and position paper rolls up to 1.5 tons.
Customization is available to meet specific roll sizes and customer requirements.
B. Advanced Conical Chuck Design
CHM Sheeter Machinery has developed a proprietary conical chuck, compatible with 3-inch, 6-inch, and 12-inch paper cores, providing flexibility for different roll sizes.
C. Automatic Braking System
Equipped with an auto-braking function, the hydraulic paper stand ensures a smooth and controlled unwinding process, preventing excessive tension or misalignment.
D. Multi-Roll Processing for Enhanced Efficiency
The system can support 2 to 6 rolls simultaneously, boosting productivity in high-speed sheeting operations.
E. Automated Tension Control
The built-in automatic tension control system adjusts the unwinding force, preventing paper breakage and ensuring consistent cutting precision.
Why a High-Quality Hydraulic Paper Stand Matters
A well-engineered hydraulic paper stand is essential for any high-speed roll paper sheeter, directly impacting production efficiency, machine lifespan, and operational stability. Choosing the right hydraulic paper stand guarantees higher productivity, reduced downtime, and improved cutting accuracy-ultimately maximizing profitability for paper converters, printing houses, and packaging factories.
If you're looking for a durable, high-precision, and cost-effective roll paper sheeting machine, investing in a high-quality hydraulic paper stand is a key factor for success.
