Saddle Stitchers — A Stitch In Time
"Saddle stitching remains the most econom-ical method of binding, and significant strides have been achieved in improvements in their efficiency and reliability," Duff maintains. "In my opinion, the future bodes well for saddle stitching machines well into the 21st century."

The following was contributed by Donna St. John Berry, manager of marketing for Muller Martini.
As a world market leader in saddle stitching, Muller Martini designs and manufactures more saddle stitchers each year than all of its competitors combined. These include simple-to-operate, entry-level machines; versatile, mid-range stitchers; as well as sophisticated and automated, high-speed publication stitching systems. With these and other products, print finishing has been the focus at Muller Martini for more than 50 years.
Specifically, the company has focused on labor-savings, waste reduction and improved production benefits. There are three areas of the saddle stitcher that can benefit from improved efficiencies: the feeding area, the delivery area and the machine net-output.
Feeding Area: Users can maximize operating efficiency and minimize personnel by optimizing loading with stream feeders. Stream feeders incorporate a higher buffer capacity, as well as reduced jogging and alignment of sections. A positive and controlled deshingling of products mean fewer jam-ups. Fewer jam-ups mean less downtime and increased profits.
Users can also increase labor savings drastically with automated feeding by logs or rolls. Intermediate storage of products coming off the press by logs or rolls means more consistent signature quality, therefore reduced waste and increased profits in the bindery. Another benefit of automated loading is the elimination of repetitive motion injuries.
Delivery Area: Production efficiencies in the delivery area might mean incorporating compensating stackers for improved stack quality, equipment for in-line wrapping and strapping, as well as automatic boxing and palletizing. Products such as books, magazines, brochures and catalogs can be delivered directly from the saddle stitcher ready for shipping without any human intervention.
