We are pleased to introduce a dynamic new bookbinding product from OMM Marchetti.
VANGUARD-PIONEER Book Binding System
Applications:
Perfect bound softcover books sewn; books with softcover
Book blocks for photo-books, also with photographic paper
Book blocks with endpapers and lining for hardcover binding
ADVANTAGES OF VANGUARD:
Closed and integrated PUR system with nozzles for maximum safety
Waste of glue reduced to a minimum
Simple cleaning of glue injectors
Extremely flexible size changes
Possibility to use all brands of PUR available on the market
Automatic Size Change:
The machine is equipped with an automatic working cycle, offers com¬puter controlled size changes, which are performed auto¬matically in a few seconds for easy operation as well as a closed and integrated glue application system (NPS PUR System patented) for simultaneous spine and side gluing.
The small amount of glue in the tank (2 kg) allows a short start-up (approx. 13 minutes for glue heating) and limited energy consumption. As an indication, the capacity of the tank allows uninterrupted production of approx. 700 books of 10 mm thickness. (*)
Book covers (for thick covers pre-scoring is recommended) are placed individually, by the operator, at the register po¬sition. By entering the total width of the cover, the register pusher will automatically move to the correct position to ensure perfect centering of the book block. With a symmetric cover, the center position will automatically be reached even when changing book thickness. When this mode of operation is selected, there will be no need for any manual adjustment to feed blocks with different thicknesses in sequence.
The size of the cover and book block (head-to-tail) must be entered by the operator. It is possible to control the start and stop of the glue application with micrometric adjustments. Side gluing can be selected between 0, 4 or 8 mm by means of a 3-way nozzle.
An air pressure control unit allows the operator to increase or reduce the quantity of glue and optimize consumption. After a few minutes of machine standstill, the glue nozzles close automatically to avoid spoilage of glue due to air ex¬posure.
The milling-notching unit:
Allows adequate spine prepa¬ration for any type of paper and thickness. Special knives mounted on the milling wheel are interchangeable and usable on 3 sides for long-lasting operation. A mechani¬cal adjustment allows the operator to change the level of the feeding of the book block so that the milling area can vary be¬tween 0 and 2 mm. In the case of sewn books, the milling station can be tilted away.
After milling/notching the book block is transported by the clamp in register position with the cover. In this station the spine and side glued areas are pressed. Depending on the type and thickness of the cover, dwell time can be graduated between 0 and 20 seconds.
Upon completing the cycle, the clamp opens automati¬cally and the operator can remove the book.
Book blocks for hard cover casing-in (option)
With VANGUARD it is possible to automatically apply in one single pass two endpapers and the lining material to a book block, for hardcover bookbinding. The endpapers are pre-gathered with the book and before starting the movement of the clamp are lifted upwards. The side-gluing nozzles will apply glue on the two sides with a double line so that both book block and outside face of the end¬papers will be glued simultaneously. Once registered with the spine, the endpapers are glued to the book and ready for the application of the lining strip which has been posi¬tioned by means of special guides onto the cover feeding station. After the spine and side pressure, the book block can be removed by the operator.
A standard machine can work with PUR or Hot Melt glues. When both systems are required for frequent job (glue) changes, an additional unit (hot melt tank+ cleaner) can be factory-installed as an option.
