Glendale SpeedBind 420CF

SpeedBind 420CF – Automated Cover Feeder Perfect Binder

The SpeedBind 420CF meets the growing demand for professionally bound documents and books where quality presentation, quick turnaround, and ease of operation are essential. Building on the standard 420, the 420CF adds automated cover feeding with spine and hinge creasing, making it perfect for high-volume production where operator time needs to be minimised.

This binder can produce A3, A4 Landscape, A4, A5, and A6 perfect bound books and documents.

Automated Cover Feeding

The SpeedBind 420CF includes a precision suction-based automated cover feeder. Covers are automatically fed into the clamping station with spine and hinge creasing applied. The system includes missing-cover cutoff protection, and once the operator loads the book block, the binding sequence runs automatically, reducing production time while maintaining professional results.

Control System

Operation is via an intuitive colour touchscreen panel. All settings — including operation mode, glue temperature, clamp pressure, clamping time, and speed — are managed from the touchscreen. Setup is completed within seconds, ensuring consistent results across varying book sizes. Minimal operator training is required.

The binder will automatically measure the thickness of the book and adjust its running speed accordingly. This feature ensures optimal performance based on the specific requirements of each book, enhancing efficiency.

Spine Preparation

Spine preparation is performed using an extra-durable milling and notching disc equipped with:

• 20 milling teeth
• 2 notching blades

Before glue application, the book block passes over the disc to break down paper fibres on the spine. This process allows superior glue penetration, improving binding strength and durability.

Glue System

The SpeedBind 420CF features a single glue tank for both spine and side gluing. Designed for modern high-strength EVA adhesives, it eliminates the need for separate adhesives. A tail structure stabilises the glue layer on the spine before the book block meets the cover. Excess glue is removed automatically, ensuring precise application and clean, professional finishes. A pre-melt groove structure allows the operator to add glue without stopping the machine, improving overall binding efficiency.

Clamping System

The adjustable clamping station allows fine control of:

• Clamp pressure – prevents over- or under-clamping
• Clamping time – adjustable for different paper and cover materials

This ensures a perfectly squared spine and consistently high-quality binding results.

Dust Extraction

An integrated paper dust extraction system collects paper dust in a cloth bag during milling and notching, reducing internal buildup and maintaining clean, reliable performance.

Padding Mode

In addition to book binding, the SpeedBind 420CF includes a padding mode for producing pads and similar products, increasing production flexibility.
