At DeChangYu, we engineer our converting lines with a strict focus on maximizing your raw material ROI. We understand that in tissue manufacturing, minimizing paper waste directly translates to higher profitability.

Our machinery achieves a consistent overall yield rate of over 98% through several advanced technological integrations:

• Servo-Driven Web Tension Control: We utilize high-precision servo motors and stepless speed regulation to maintain optimal web tension from the unwinding stand to the rewinder. This prevents over-stretching and drastic tension fluctuations, significantly reducing the chance of web breaks.

• Automated Web Guiding System (EPC): Our machines are equipped with edge position control sensors that automatically align the jumbo roll during operation. This ensures perfect edge-to-edge alignment, minimizing the necessary trim width and reducing edge waste to the absolute minimum.

• Smart Break-Detection Sensors: Intelligent sensors monitor the paper web in real time. If a web break is detected, the machine triggers an immediate auto-stop, preventing massive paper jams and material loss within the machine rollers.

• Precision Splicing and Tail Sealing: For toilet roll and kitchen towel lines, our optimized tail-sealing technology ensures precise glue application (or glue-free sealing), eliminating messy ends and reducing the amount of rejected rolls during the final packaging phase.

Maximize Your Profit Margins: Every millimeter of saved paper adds to your bottom line. Contact our technical sales team today to learn more about our waste-reduction designs or to request a detailed ROI calculation for your specific jumbo roll specifications.

The maximum stabletissue converting machine speed and daily output depend entirely on the specific machinery model, your final product specifications, and the complexity of the converting process (such as the inclusion of lamination, edge-embossing, or color printing).

Because DeChangYu manufactures a comprehensive range of equipment, the technical parameters differ significantly across categories. For example, the output metrics for our high-speed toilet paper rewinders are calculated in meters per minute (m/min), whereas our multi-lane facial tissue folders and napkin machines are measured in logs or sheets per minute. Furthermore, your actual daily yield will be directly influenced by your specific jumbo roll parameters (width, grammage) and the target mechanical efficiency of your facility.

Get a Customized Production Projection: We believe in providing precise, data-driven solutions rather than generic estimates. Please contact our engineering team with your specific product requirements (ply count, target dimensions, and expected daily tonnage). We will analyze your operational needs and provide a tailored technical proposal, complete with exact operating speeds, guaranteed daily output metrics, and the optimal machine configuration for your factory.

Understanding your tissue converting machine capacity is crucial for facility planning, inventory management, and ROI calculation.

8-Hour Output (kg) = [ Web Width (m) × Speed (m/min) × Grammage (g/m²) × Plies × 480 mins × Mechanical Efficiency ] ÷ 1000

Here is a breakdown of what each variable means:

• Web Width (m): The effective working width of the jumbo paper roll you are processing.

• Machine Speed (m/min): The operational running speed of the converting line.

• Grammage (g/m²): The basis weight (thickness) of a single layer of tissue paper.

• Plies: The number of layers in your finished product (e.g., 2-ply, 3-ply).

• 480 mins: The total number of minutes in a standard 8-hour shift (8 hours × 60 minutes).

• Mechanical Efficiency (%): This is a critical real-world factor. It accounts for the actual running time after deducting inevitable stops for jumbo roll changes, web breaks, or daily maintenance. A high-quality line typically operates at 80% to 95% efficiency.

• ÷ 1000: This converts the final result from grams into kilograms (kg) for standard industrial measurement.

Calculation Example: Let's assume you are running a DeChangYu high-speed rewinder to produce standard 2-ply toilet paper with the following parameters:

• Web Width: 2.85 meters

• Machine Speed: 200 meters/minute

• Grammage: 15 g/m²

• Plies: 2

• Mechanical Efficiency: 90% (0.90)

The Math: (2.85 × 200 × 15 × 2 × 480 × 0.90) ÷ 1000 = 7,387.2 kg

Conclusão: Under these operational parameters, the machine will realistically produce 7,387.2 kg (approx. 7.38 tons) of tissue paper per 8-hour shift.
