Saddle Stitch Wire Stapling Station

This video shows gathered booklets moving through the wire stapling station on an automated saddle stitch line.

What this video shows

The booklet has already been gathered in the correct page order before it reaches this station. In the video, it moves along the belt into the wire stapling section.

On the left side, you can see the staple arm move along with the belt. The belt keeps moving for efficiency, and the arm travels with the booklet while placing the wire staples through the center fold. This makes stapling a smooth, continuous step instead of a stop-and-start process.

On the right side, there is a small holding or alignment station. It briefly holds the gathered booklet so the pages can stay square before stapling. This helps the staples land cleanly and keeps the finished booklet neat.

Why does the staple arm move with the belt?

The belt is designed to keep moving so the line can run efficiently. If the belt had to stop for every booklet, the process would be slower.

The moving staple arm solves that problem. It follows the booklet for a short moment, places the wire staples through the center fold, and then resets for the next booklet.

Why does the booklet align briefly before stapling?

The small holding station keeps the gathered booklet square before the staples are placed. That matters because the staples need to land cleanly through the center fold.

If the booklet shifts before stapling, the staple position can look uneven or the pages may not sit neatly together.
