Butt to Butt Unwinder Splicing

Zero‑Speed Head‑to‑Head Splicing for Continuous Feed The FL‑series non-stop butt-joint unwinder is a high-end automatic web handling system engineered for flexo, offset, and wide-web converting applications. It operates via a zero-speed butt-splice mechanism: as the running roll nears completion, the web momentarily stops, the trailing edge is aligned and cut cleanly, and then dual-sided adhesive tape is applied to join the old roll to the new one in a head‑to‑head fashion, ensuring a flat, tape-bonded seam. This method effectively avoids issues like crushed or overlapped paper that can compromise the quality of downstream resin-based printing. This butt‑joint technique, unlike lap splices, doesn’t create thick splices that could jam printing units. Instead, it delivers a seamless transition that maintains precise web tension and minimal thickness variation—critical when maintaining registration and web stability through subsequent drying, embossing, or coating processes.
