Spectrum Systems Ltd. Newest Product VANGUARD-PIONEER Perfect Binder
by OMM Marchetti
ADVANTAGES OF VANGUARD:Closed and integrated PUR system with nozzles for maximum safetyWaste of glue reduced to minimumSimple cleaning of glue injectorsExtremely flexible size changesPossibility to use all brands of PUR available on the market
APPLICATIONS:
Perfect bound soft cover books sewn; books with soft cover Book blocks for photo-books, also with photographic paperBook blocks with endpapers and lining for hard cover binding
OPERATION:
Automatic Size Change: The milling-notching unit:
The machine with an automatic working cycle, offers computer controlled size changes, which are performed automatically 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 (4.4 lbs.) 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 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 of any manual adjustment to feed blocks with different thickness 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 exposure.

Allows adequate spine preparation 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 mechanical adjustment allows the operator to change the level of feeding of the book block so that milling area can vary between 0 and 2 mm. In 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 type and thickness of the cover, dwell time can be gradu¬ated between 0 and 20 seconds. Upon completing the cycle, the clamp opens automatically and the operator can remove the book.
Glue Nozzle and Tank: Touch Screen:
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 hard cover 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 that has been posi¬tioned by means of special guides onto the cover feeding station. After 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.
