HXDK520 Automatic Bundling Machine with 3000N Pressure for Vertical Stacking Delivery

In large-run folding signature production, efficient, labor-free stacking and bundling are critical to streamlining post-press workflows. The HXDK520 Automatic Vertical Stacking and Bundling Machine integrates seamlessly with upstream equipment, delivering fully intelligent automatic processing — making it ideal for high-volume printing and binding facilities.

The HXDK520 is designed for seamless integration. It can be connected directly to a web press printing machine or a paper sheet folding machine, forming a continuous production line for folding signatures. This integration eliminates manual material transfer, reduces downtime, and ensures a smooth, efficient workflow from printing or folding through to stacking and bundling.

The core function of the machine is folding signature collection. Signatures are collected vertically — a design that keeps them neat and aligned throughout the process. Vertical collection avoids the deformation and misalignment that often occur with horizontal stacking, preserving the integrity of the folded signatures.

After vertical collection, the HXDK520 automatically tidies the signatures by pressing and flapping the stack neat, ensuring every stack is uniform and properly aligned before moving to the next stage. This step eliminates manual adjustment, reduces labor input, and ensures consistent stack quality across every batch.

Once the stack is neat, the machine automatically pushes it to the bundling station, where it performs two key operations: inserting clapboards at both ends to protect the signatures, followed by 3000 N pressure pressing and automatic bundling of the stack for secure, stable packaging.

The HXDK520 is specifically designed as a fully automatic delivery solution for large-run folding signature production. It handles high-volume tasks without compromising efficiency or quality, and its automated workflow is tailored to meet the demands of large-scale production — ensuring consistent output even during long-running operations.

A standout advantage of the HXDK520 is that it requires no laborer, completely automating the entire intelligent folding signature stacking and bundling process. This eliminates labor costs, reduces human error, and allows operators to focus on monitoring and maintaining the production line — significantly improving overall productivity.

The HXTP650 Two-Way Pressing Machine is designed for book block processing and complements the HXDK520 in a complete post-press workflow.
