VBF Stahl BL 500

Technical specification

One fully automatic book production line BL 500, consisting of:

1. Core Bookline RHE 525

With centrally selectable automatic adjustment system CAC/COS for the production of case-bound books.

It is possible to process both thread-sewn and adhesive-bound book blocks, with rounded or square spines, and to hang in covers with rounded or square spines.

Machine equipment:

• Electronic measuring system for format input of book block and cover into the CAC/COS system

• Adjustment motors for automatic machine setup

• Timing carriage and continuous chain conveyor system for format-retaining book transport

• Quick-change devices for interchangeable parts

• 1st gluing and gauze station

• 2nd gluing and headband/backlining station

• Pneumatically controlled forming cushions for full-surface pressing of the backlining material

• Numerical input of cutting width for gauze and backlining material

• Stepper motors for precise feeding of gauze and backlining material

• Universal divider for head or foot alignment with block rounding unit

• Cover opening station (DAS)

• Cover forming unit (spine molding), thermostat-controlled up to 300°C, with automatic lowering

• Folding-in unit and glue roller system incl. cleaning trays

• Delivery and infeed conveyor to folding-in and pressing machine EP 608/L

Format Ranges (standard sizes)

Book block:

• Max: 270 × 380 × 75 mm

• Min: 100 × 100 × 5 mm

Finished book:

• Max: 280 × 390 × 80 mm

• Min: 105 × 105 × 5 mm (+ cover thickness)

Opened cover:

• Max: 650 × 390 mm

• Min: 210 × 105 mm

Cover thickness:

• Max: 5 mm

* With special thin-book rounding device (optional): block thickness from 2 mm possible

2. Folding-in and Pressing Machine EP 608/R

For fully automatic pressing-in of hung-in books with uninterrupted, thermostatically and pressure-controlled pressing plates for spine and cover surfaces.

Books are fed from the delivery belt of the core bookline into the EP 608.

Via a distribution table, two books are loaded simultaneously into two pressing stations and unloaded at the delivery station.

This unique and patented technical solution enables a 50% increase in mechanical cycle speed, i.e. 26 cycles at a nominal output of 52 books/min.
