Four Side Wrapping Machine

A Four Side Wrapping Machine is a specialized piece of equipment used in the final stage of producing hardcover items. It automates the precise wrapping of cover paper around a cardboard core (grey board) on all four edges. It is essential for manufacturing book covers, album covers, calendar covers, and premium rigid box sleeves with a clean, professional finish.

Absolutely. A core strength of our design is modularity. Our semi-automatic wrappers can function as standalone workstations, while our fully automatic models are engineered for seamless integration. They can be connected upstream with our Automatic Paper Gluing Machines (like the PC-650A/850A) and downstream with pressing or stacking units to create a continuous, end-to-end hardcover production line.

Our series is built for versatility across the publishing and packaging industries:
Cover Size Range: From small diary covers (e.g., 150mm x 90mm) up to large-format album or box sleeves (e.g., 1000mm x 500mm or custom sizes).
Material Compatibility: Designed to work with a wide array of covering materials (100-250gsm paper, leatherette, etc.) and standard grey board thicknesses (typically 1.2mm to 4.0mm).

Automating with our machines delivers significant advantages:
Unmatched Consistency & Quality: Eliminates human error, ensuring every cover has identical, perfectly tight edges and corners.
Increased Production Speed & Output: Dramatically outpaces manual wrapping, with speeds ranging from 20 to over 50 covers per minute depending on the model.
Reduced Labor Costs & Skill Dependency: Lowers reliance on highly skilled manual labor and reduces physical strain.
Improved Material Yield: Precise control minimizes glue waste and reduces material damage from rework.

The PC-900 is a semi-automatic four side wrapping machine. This means it automates the critical wrapping and pressing processes for high consistency and speed (20-30 units/min), while requiring an operator to manually load the assembled cover (cardboard with glued paper). This design offers an excellent balance of cost-effectiveness, productivity, and flexibility, making it ideal for small to medium batch production.
