Tissue Folding Machine Working Principle: V-Fold, Interfold and Soft Pack Output

Table of Content [Hide]

    A tissue folding machine is the core equipment in facial tissue and soft pack tissue production. It determines fold accuracy, sheet alignment, stack quality and the stability of downstream packing. Understanding how the machine works helps buyers choose the right model for V-fold, interfold and high-speed tissue converting projects.

    How a Tissue Folding Machine Works

    A tissue folding machine unwinds jumbo rolls, slits the paper into required web widths, guides the web through folding plates or vacuum-assisted folding systems, cuts the sheets and stacks them into a continuous interfolded tissue stack. The finished stack can then be transferred to cutting, compressing and packing equipment.

    The working principle sounds simple, but stable production requires precise tension control, accurate paper guiding, reliable folding timing and clean cutting. Any instability in the folding section can cause crooked stacks, broken sheets or packing problems.

    • Unwinding controls the parent roll and web tension.

    • Slitting divides the paper into the correct lanes.

    • Folding creates V-fold or interfolded tissue sheets.

    • Cutting and stacking prepare the product for soft pack or box tissue packaging.

    V-Fold and Interfold: What Is the Difference?

    V-fold tissue is folded into a V shape so the next sheet is pulled up when one sheet is taken from the pack. Interfolding improves dispensing convenience and is widely used in facial tissue, boxed tissue and soft pack tissue products.

    For buyers, the key question is not only whether the machine can make V-fold tissue, but whether the finished sheet size, stack height and dispensing performance match the target pack design.

    • V-fold is common for facial tissue and soft pack tissue.

    • Interfolding improves sheet-by-sheet dispensing.

    • Accurate folding reduces waste and improves consumer experience.

    Factors That Affect Folding Quality

    Folding quality depends on paper softness, tensile strength, moisture level, web tension and machine adjustment. Low-quality paper can tear during high-speed folding, while unstable tension may create misaligned sheets. A good facial tissue folding machine should be able to keep stable output across the recommended paper specification range.

    Buyers should ask for test production using paper similar to their local supply. A machine tested only with ideal paper may not perform the same with different GSM, embossing depth or softness.

    • Paper GSM and parent roll quality.

    • Tension control and web guiding accuracy.

    • Folding plate design or vacuum folding stability.

    • Blade sharpness and cutting system maintenance.

    • Operator training and size changeover procedure.

    How Folding Connects With Packing

    The folding machine should be selected together with the packing plan. If the tissue stack height is not stable, the wrapping machine or bagging machine may produce loose packs, wrinkles or sealing problems. In high-speed lines, automatic transfer between folding and packing is important for reducing labor and avoiding stack deformation.

    When planning a complete facial tissue production line, buyers should define the finished pack first, then design the folding, cutting, compressing and packing sections around that pack.

    • Confirm tissue sheet size and stack count before machine selection.

    • Check whether the output direction matches the packing machine layout.

    • Plan enough buffer space between folding and packing when required.

    Maintenance Tips for Stable Output

    Routine maintenance keeps folding accuracy stable. Operators should inspect blades, belts, bearings, paper guiding parts and dust accumulation. Tissue converting creates paper dust, so cleaning is not only a hygiene step but also a performance requirement.

    A reliable supplier should provide training, spare parts guidance and troubleshooting support for common issues such as uneven stacks, sheet breakage, poor dispensing and unstable counting.

    • Keep blades sharp and replace them before burrs appear.

    • Clean paper dust from sensors and moving parts.

    • Record settings for each SKU to reduce changeover time.

    Frequently Asked Questions

    What products can a tissue folding machine make?

    A tissue folding machine can make facial tissue, soft pack tissue, boxed tissue and interfolded tissue products, depending on the machine design and downstream packing configuration.

    Why does folded tissue become uneven during production?

    Uneven tissue stacks can come from unstable web tension, paper quality variation, blade wear, incorrect folding adjustment or poor transfer between folding and packing machines.

    Should I buy a folding machine alone or a full tissue production line?

    If you already have packing equipment and operators, a folding machine may be enough. If you want higher output and lower labor cost, a complete folding, cutting and packing line is usually more efficient.

    Hi, I’m the founder of Zhejiang Onepaper Smart Equipment Co., Ltd.  Eric Wang, You can call me Eric, senior engineer, a long-time practitioner in the field of automated tissue paper equipment.


    With over 20 years of experience, always focused on one thing: how to use intelligent equipment to make tissue production lines fold faster, more beautifully, and more efficiently.


    In 2010, I founded Zhejiang Onepaper Smart Equipment Co., Ltd  

    Over the past fifteen years, we have served more than 1,000 factories across 60+ countries worldwide, including well-known tissue brands such as APP, Kimberly-Clark, Vinda, and Jin Hongye.

    What makes me proud is that one of our customers has repurchased our machines 29 times.

    This is undoubtedly a high recognition of our product quality and service, and the best proof of Onepaper's consistent commitment to the philosophy of “quality first, customer foremost.”


    What we have always adhered to is a kind of "craftsmanship spirit":

    Laozi said, "Governing a large country is like cooking a small fish." I believe that running a business is about being a good person. With a kind heart, thinking of others, not judging by gain or loss, but by right and wrong, good and evil.


    Wang Yangming said, "One becomes a sage only by pure principle, and gold is refined only when it reaches full purity." We do not pursue the size of the enterprise, but the character and broad mind of the enterprise. Running a business is not just about price competition, but about value. Pursuing employee happiness and customer happiness is our greatest value proposition. Creating a small yet high-quality, respected, and century-old enterprise is my lifelong dream.


    On our entrepreneurial journey, we have experienced hardships and difficulties, and received help from many benefactors — you are one of them. I am deeply grateful and firmly rooted in this dream: to work steadily and diligently on products and services, and to proudly pursue poetry and the horizon.
