The **LD‑3SB** by Signode (Little David®) is a **semi-automatic, uniform case sealer** designed for efficient top-and-bottom sealing of corrugated boxes—perfect for tall, narrow, or lightweight cases, even those as small as 3¼″ wide with the narrow-box option.

* **Side‑belt driven feed** handles unstable or lightweight boxes with stability.
* **Operator-friendly design** includes self-centering belts, single-mast access, and tool-free blade/roller changes for fast changeovers.
* **Robust build** features a heavy-duty steel mast and welded head/platform for 24/7 reliability.
* **Compact footprint** with a continuous belt speed of ~72 ft/min (22 m/min).
* **Wide sealing range**:
* Length: 4½″ (114 mm) to unlimited
* Width: 4″ (102 mm) to 20″ (508 mm) (down to 3¼″/90 mm with option)
