Industrial Pulp and Paper Automation
Improve Line Stability and Sheet Quality Across Pulp and Paper Operations
Small changes in moisture, fiber distribution, and line speed can ripple through pulp and paper processes, making consistency difficult to maintain at production scale. Quad Plus delivers pulp and paper automation through coordinated drive control systems and process automation to stabilize machine sections, improve control accuracy, and support reliable continuous operation from forming through finishing.
With deep industry knowledge and advanced system diagnostics, our engineering team works to optimize every component of your operation, from drives and motors to HMIs, PLCs, and process instrumentation.
We support pulp and paper operations through:
- Line optimization focused on speed balance and stability.
- Process design and automation built for continuous paper production.
- Online measurement for real-time paper profile control.
- Operational assessments that identify performance gaps and risks.
Results: Stable Lines. Improved Profiles. Consistent Quality.
Why Quad Plus?
Maximizing operating time while improving efficiency on an existing paper machine or winder can be challenging. How do you do this? By working with a trusted partner that can evaluate your current processes and identify opportunities to improve performance through automation and control system enhancements.
Quad Plus has experience in paper production and practical pulp and paper engineering. We will assess your current operations and provide customized solutions to reach your specific paper mill productivity targets. During the design phase, we utilize advanced process control technologies to model and verify system behavior before implementation, thereby reducing shutdown time.
The same engineers who design your solution then perform onsite installation and commissioning of the entire system. This consistency ensures that newer technology and controls work as intended with your existing equipment.
Pulp and Paper Application Challenges
Solving web breaks, reeling wrinkles, slippage, and paper defects at their source can reduce the risk of emergency stops and off-spec product rolls. Evaluating web tension and speed differentials, both in the winder and throughout the paper machine, can help diagnose and prevent flaws. Integrating real-time measurements can ensure that moisture content, web profile basis weight, and thickness parameters are within the target range.
Bottlenecks can significantly limit your overall production capacity in both the paper machine and the winder. Slowdowns and limitations can take the form of manual slitter adjustments, outdated control technology, equipment capacity limitations, vibration issues, and inefficient drive systems. These issues should first be identified through machine data analysis. From there, they can be addressed through automation improvements, system optimization, and control upgrades. Where necessary, legacy equipment can be replaced.
Mitigating hazards and meeting environmental standards are critical steps to boost personnel safety. These changes can also reduce liability concerns and support higher production capacity. Improvements such as automated slitter positioning, automated web threading, safety controls, guarding, fencing, and compliance with TAPPI and IEEE standards help reduce risk throughout the operation.
How Pulp and Paper Automation Improves Paper Mill Operations
You’ve already optimized a section of your line to increase capacity, but then you begin to experience a bottleneck or slowdown in subsequent segments. To resolve these unintended consequences, the entire web handling process should be evaluated to identify where improvements are needed.
The evaluation begins with an assessment of all current control systems and process capabilities, available technologies, and product characteristics throughout the machine. Using advanced process control modeling, solutions can be designed to reduce speed differentials between machine sections. The goal is to improve paper manufacturing efficiency without creating new bottlenecks elsewhere in the process.
Motors for the pulp & paper industry and coordinated drive systems should be selected and designed for each section based on normal running load (NRL) and recommended drive capacity (RDC) calculations. Sectional motor load-sharing capabilities also help determine the power needed to accommodate speed differentials throughout the machine.
Control systems must continually monitor and respond to changing operating conditions throughout the machine. Removing slowdowns and bottlenecks to the winder is critical to optimize performance. Effective systems require precise tension control, responsive motion control, efficient communications, and the ability to operate reliably at high speeds. These allow for rapid, dynamic changes to speed and torque while ensuring the product is unwound from parent rolls, slit, trimmed, and rewound without damage.
Pulp and Paper Automation Solutions for Enhanced Production Efficiency
Implementing new process control methodologies can address inefficiencies throughout the papermaking process and increase overall pulp and paper production. The results can include extending the life of your existing equipment while reducing changeover times, increasing speed, capacity, and productivity, and stabilizing product quality control.
Automation can improve:
- Paper grade changes
- Parent reel changes
- Slitter adjustments
- Blade changes.
Plus, rebuilding inefficient sections of the line can supply measurable returns on your investment. Automating risky manual processes also increases overall safety. Your personnel can manage recipes, paper grade changes, and slitter adjustments from outside the paper machine and winder.
Integrating Automation for Better Quality Control in Paper Production
Web gauging system integration enables real-time, continuous measurement of paper thickness, basis weight, moisture, and machine direction (MD) and cross machine direction (CD) tension profiles at critical points. These systems also support machine direction control for pulp applications that require consistent product quality.
Monitoring and correcting profile and quality disturbances optimizes wet-end stability, reduces product variances, chemical usage, and paper web breaks, resulting in increased productivity and capacity.
As measurements are collected, the data is stored in a database for post-production reporting and analysis. The reporting tools allow identification and comparison of product qualities to determine the root cause of issues.
The Benefits of Paper Mill Automation for Sustainable Manufacturing
Sustainable manufacturing requires more than reducing energy consumption. Safe operations, reliable equipment, and efficient production processes all contribute to long-term performance. Through safety assessments, remote support, repair services, and power studies, Quad Plus helps pulp and paper facilities enhance operational efficiency while supporting sustainability goals.
