Saddle Stitch Booklet Feeding Slot

This 22-second video shows one feeding slot on an automated saddle stitch booklet line. A stack of printed spreads sits in the slot, and the machine drops one spread at a time onto the moving belt so the booklet can be gathered in the correct order.

What this video shows

This clip is focused on the feeding station, not the stapling head. After the booklet pages have been prepared as spreads, each spread is loaded into its own feeding slot. The video shows one of those slots releasing a spread onto the moving belt.

As the belt moves, the machine drops the innermost spread first. Then the next spread drops on top, then the next, until the cover is added. By the end of the gathering section, the booklet is already stacked in the correct order and ready for the stapling step.

How many booklets can this line gather per hour?

At full speed, this automated saddle stitch line can gather about 4,000 to 6,000 booklets per hour. This makes it a good fit for large print runs because the machine can gather and staple booklets quickly and consistently, helping keep the unit cost more economical when producing many copies.

What happens after the spreads are gathered?

After all spreads and the cover are gathered, the booklet moves forward to the stapling area. That next step places wire staples through the center fold so the pages hold together.
