|Excellent lay-flat quality irrespective of the spine thickness - from 2mm booklets to massive coffee table books.|
|High binding strength (40kg) and flexibility. Once cured, it is very difficult to tear out a page from a PUR-bound book.|
|PUR can bind any kind of paper - UV- coated, aqueous-coated, laminated or foiled. Great results when binding thick stock.|
|Unaffected by ink migration into the spine.|
|Lower working temperature (120oc for PUR vs 170oc for EVA) saves electricity|
|Completely avoids labour and time-intensive signature stitching|
The NPS Patented System allows you to reuse the PUR candle up to 25 times, which makes it as economaical as an EVA hot-melt binder, but much more advanced with respect to quality and productivity
The System 500 is equipped with a double slot applicator and dual tank - making it a heavy duty PUR + EVA binder that can belt out over 550 cycles per hour, without compromising on quality and cost-effectiveness
The professional single-clamp medium range perfect binding machine of the PB PUR System 500 range: up to 550 cycles per hour for excellent quality results with PUR and/or Hot Melt glue application depending on model and options of your choice.
This model allows the installation of 2 gluing stations (option) so that it may be possible to change from PUR to Hot Melt gluing by simply selecting the mode of operation on the panel, without any change of parts or cleaning of the glue tank.
The experience of 4B-Four Bind engineers dates back to the very start of the introduction of PUR technologies for small perfect binders. The NPS closed glue application system with small glue tank integrated in the machine offers the fastest makeready, easy and clean operation and minimum glue consumption.
Loaded with features, the EXPLORE can be used for all type of papers, different signatures with cutting depth adjustable up to 4 mm, book blocks for hard cover binding with optional endpaper and lining in one single operation.
The integrated measuring table enables automatic entry of the values of thickness and spine length of the book block and sizes can be varied constantly so that books of different thickness can be produced in sequence without manual adjustments.
The spine pressing unit at the infeed of the clamp (optional) ensures quality binding of books made of folded signatures, sewn book blocks, coated and slippery papers.
The tilt-away milling station allows production of sewn book blocks without damage
The adjustable height of the pressing unit is a big advantage in production of books with covers of different weigths
A pre-assembled combination of 2 endpapers with centre strip can also be fed from the cover feeding station.
Scoring depth can be varied automatically by means of a simple mechanical thickness setting unit (like folding machines).
Quality of perfect bound books is maintained at the delivery of the machine with gentle descent into sliding chute where a conveyor can be installed to connect the Explore to a three-knife trimmer. Optionally, the machine can be supplied with a vertical stacker.
|NPS Patented System with Closed Pot Tank (Fig.1)
The NPS System and Closed pot Tank make application of PUR very efficient and cost-effective, allowing PUR to be used multiple times without wastage.
|Smart Touch Panel (Fig.2)
All operations, controls and maintenance fully controlled from the unique touch screen. simple, intuitive interface. Easy to learn.
|Automatic Spine Detection (Fig.3)
The machine senses the book block thickness and automatically abjusts itself without the need for manual settings.
|Criss Cross Milling for Spine Preparation (Fig.4)
This patented technology allows the fiber of the papper to bond with PUR in 2 directions, enabling more pull strength & flatter opening.
|XL Cover kit for Larger Book Blocks (Fig.5)
All Allows you to bind larger book blocks of sizes up to 38" x 17.5" (open size).
|Self-cleaning mechanism (Fig.6)
The machine automatically cleans the PUR pot and nozzle with in a minute and at the toch of a button. Paper dust collected from milling station through vacuum.
|Unique End Sheet Adaptor
Applies Front and back end sheets precisely and effortlessly, while preparing the book block for milling, notching and nipping.
|Advanced Gauze kit
Enables smooth and precise application of lining material for hard covers of any type.
|Double Slot Applicator
With a double slot applicator, dual tank and dual milling station, the System 500 achieves a top speed of 550 cycles per hour.
|Inline Bar Creasing
Automatic Spine Detector defines height and width of the spine and applies 4 creases automatically before placing the cover at the nipping station.
|Auto Feeding & Inline Stacking
The machine senses the book block thickness and length, and automatically adjusts the cover feed and creasing without the need for manual setting.
