Butt-Joint Label Unwinder and Auto Rewinding

Ergonomic, Smart, and Waste-Reducing Non-Stop Roll Change Solution The FL series unwinder is engineered with operator-friendliness and eco-efficiency in mind. Its automatic lift-and-load system allows a single operator to change rolls safely without overhead cranes or manual lifting—activity typically reserved for cranes when handling heavy label or film rolls. When a roll nears its end, sensors trigger a zero-speed butt splice: the web stops, the edges align, and a thin tape is applied head-to-head to connect the webs cleanly—avoiding the compression issues commonly seen in overlapping splices on resin-coated surfaces . A robust tension-control loop—based on servo motors, magnetic powder braking, and dancer rollers—ensures a steady web feed throughout the operation. The horizontal-edge EPC corrects any sidelay errors, automating alignment without repeated manual tweaks. These combined features reduce scrap, speed roll changes, and simplify maintenance, leading to less downtime and low…
