The soft-surface uncoiler is a specialized piece of equipment in sandwich panel production lines specifically designed to accommodate flexible surface materials. By eliminating straightening functions and employing precise low-tension control and proactive PCC (Compact Processing) technology, it addresses the industry’s challenges of soft materials being prone to stretching, deviation, and damage during conveyance. It is a key prerequisite for the efficient and stable production of high-quality sandwich panels with flexible surfaces.
Why is specialized equipment necessary? — The core difference from metal decoilers
Traditional metal decoilers are designed to process high-strength, high-rigidity color-coated steel or galvanized steel sheets. Using them with soft materials can lead to a series of problems:
Stretching: Excessive tension can cause the material to stretch and narrow, resulting in dimensional instability and wrinkling.
Surface damage: The straightening rollers can scratch the delicate surface coating.
Misalignment: The material is too soft and easily deflects, snakes, or even gets stuck on the rollers.
Tear: Improper tension control can directly lead to material breakage.
Therefore, the design concept of a soft surface decoiler is completely different from that of a metal decoiler.
