Machine Highlights

1. Dual Handwheel Adjustment for Fast Carton Size Setup

Equipped with a top lifting handle and side locking handwheels to adjust frame height and width manually. Operators can reconfigure the machine for different box specifications without requiring external tools.

2. Simultaneous Top and Bottom Tape Application

Upper and lower tape cartridge heads apply uniform tape tension along the box centerline while side positioning wheels align the carton flaps. Eliminates seam gaps and prevents tape lifting during transport.

3. Integrated Safety Guarded Cutting Blades

The tape cutting mechanism is enclosed within a mechanical blade protection guard. This prevents operator hand injuries during tape roll replacements and routine line maintenance.

4. Modular Line Compatibility

Designed with standard working height and inline side guides, allowing seamless placement after manual packing tables or upstream case erectors.
