Customer Case Study: Cost Reduction and Efficiency Improvement Solution of Folded Turn-up Paper Tape for High-Speed Paper Machines

1. Customer Background

2. Core Production Pain Points

• Poor stability in high-speed reel changing: Conventional paper tapes feature a single structure and insufficient tensile force. They are prone to breakage during high-speed operation, leading to a high failure rate of reel changing and frequent equipment alarm shutdowns.
• Severe product loss: Uneven stress and poor fitting effect of ordinary tapes cause deep bottom indentations and irregular paper tail bonding on finished paper rolls, resulting in a large number of defective products and waste paper, and serious waste of raw materials.
• Limited production efficiency: Manual paper threading and equipment debugging are required after failures, occupying plenty of production time. The production line cannot achieve uninterrupted continuous operation, making it impossible to maximize production capacity.
• Poor equipment adaptability: Fixed specifications of universal paper tapes cannot precisely match the parameters of high-speed units. Long-term use leads to adaptation deviations and continuous decline in equipment operation stability.

3. Mingrui Customized Solution

• Upgraded structural technology: Adopting high-density composite pressing technology with 100% pure wood pulp and exclusive folded structure design, the tape balances rigidity and toughness, greatly improves instantaneous tensile resistance, perfectly adapts to high-speed reel changing working conditions and completely avoids tape breakage.
• Precise customized specifications: Customize the width, thickness and hardness of the paper tape according to the customer’s machine width and reel changing system parameters, ensuring smooth tape output, uniform stress and greatly improved fitting accuracy.
• Refined quality control: Strictly control the thickness uniformity and surface flatness of the tape, with matched bonding technology to effectively reduce bottom indentations of paper rolls and lower the defective rate fundamentally.
• Full-process technical support: Provide one-stop services including on-site installation guidance, equipment adaptation debugging and staff operation training to ensure rapid implementation and stable mass production of products.

4. Application Results

• Significantly improved reel changing success rate: The success rate of high-speed reel changing increased to over 99.8%, completely eliminating tape breakage and splicing failures and greatly extending the fault-free operation time of equipment.
• Optimized product yield: The problem of paper roll bottom indentations is basically solved. The appearance quality and regularity of finished paper are greatly improved, and waste paper loss is reduced by more than 30%.
• Improved production efficiency: Frequent shutdown debugging and manual rework are eliminated. The production line realizes real uninterrupted continuous production, with the overall production capacity increased by 8%–12%.
• Reduced comprehensive production costs: Raw paper loss, labor operation and failure shutdown losses are greatly reduced, saving substantial annual production costs for the customer and realizing dual goals of cost reduction and efficiency improvement.
