Spineflex SP320
The ultimate in layflat binding technology

  
The new Spineflex layflat binding machine

What makes this machine the best in our range?

The Spineflex SP320 represents the latest in cutting edge binding technology. Producers who are in touch with their markets will all agree that the most urgent need in the binding industry is the need for affordable layflat books. Layflat refers to books that will lie open flat without snapping shut spontaneously.

While perfect binding still dominates the market, this binding method is singularly unable to produce layflat books. Some perfect binders yield better results than others, but on the whole, perfect binders cannot bind layflat owing to the thick spine that books require.

Until now there have been few alternatives. Smythe sewing of books (with needle and thread) yields the desired results but in most cases it is far to slow and expensive. Fanbinding books by hand, using water-based PVA glue is a time-proven and extremely effective method. But this too, is by far too slow and expensive to be useful on a commercial scale. The third method has been PUR binding, which yields fair layflat results on an industrial scale. The problem with PUR binding is just that the machines are extremely expensive and complex to run. Their price puts them well beyond the reach of small and medium book producers. PUR machines are also not well suited to short production runs. Once started, they need to be used on long continuous production runs. The complexity of PUR machines means that mistakes are easy to make and can be extremely costly since the curing time for PUR glue is long and defective binding is usually only discovered after a great amount of stock has been produced.

What producers have long been waiting for is a machine of which the cost compares to good perfect binding machines, a machine which is easy and uncomplicated to operate, a machine that is suited for short production runs - and most of all - a machine that yields total layflat results.

The Spineflex does all of these things.

How does it work? 

The difference between doublebinding and standard glue binding technologies such as perfect binding or PUR, lies in the fact that glue is applied not only to the tips of paper, but also in-between pages.

Doublebinding applies glue in-between page leafs.

The Spineflex achieves this by fanning the book pages mechanically when the book passes across a standard glue roller. In other words, the pages are separated by a mechanical process that happens so fast that it can almost not be seen. The accompanying video clip will show the travel of the book, but the fanning process is screened behind the clamping mechanism and isn't visible. The process is extremely fast and efficient and consistently yields excellent results. The fact that no paper cutting is required makes this a very quiet and fast process.

This process applies a minute layer of hotmelt EVA glue on both sides of every single page in the book. This creates the required doublebinding effect which makes the books so strong. The fanning process is precision-engineered and does not skip pages. Every page in the book from the first to the last receives an equal coating. This is what makes the process so unique. It is a process that succeeds in doing what engineers and designers have been trying to achieve for 100 years already. And it works every time.

In essence, the Spineflex is the mechanised version of traditional fanbinding which used to be done by hand. Many old generation binders will be quick to point out that this method of hand binding has always yielded the highest quality books of all. With a Spineflex this same quality is still possible - but now a machine can do what used to be possible only by hand.

Frequent Questions

  1. What kind of glue is used?
    A standard product hotmelt EVA glue is used. It is similar to EVA glue which is used in perfect binding machines, but the formulation for doublebinding purposes is different. The glue that is used in standard perfect binders will not work at all.
  2. How is the glue obtained?
    The glue can be bought internationally from one of the biggest independent glue manufacturers in the world. The glue can be either ordered from our factory or from the glue distributors directly. There are distribution centres in most of the world's major cities. The product code is only made available upon receipt of a confirmed order.
  3. What servicing does the machine require?
    No scheduled servicing is required. There are not cutters that have to be replaced. The single most important requirement is that the machine should always be kept clean from glue spillage.
  4. What is the production capacity?
    145-160 books per hour, operator-dependent. The accent is on flexible, strong, layflat books.
  5. What is the maximum thickness that can be bound?
    30mm
  6. What is the minimum thickness that can be bound?
    1mm
  7. What is the maximum size books that can be bound?
    320mm spine length.
  8. What are the machine's dimensions?
    1,2m wide, 1,25m high and 0.6m deep. The weight is 160kg.
  9. What is the curing time before books can be trimmed?
    15 minutes
  10. What does the glue cost?
    The glue cost is low enough that it is usually not included in costing of jobs, as with overhead costs such as electricity, insurance, etc.
  11. Does the machine have CE registration?
    The machine is not CE marked yet. Customers from EU member countries should take this into consideration.
  12. Is commissioning required?
    Yes the machine has to be installed and commissioned by a technical engineer. This cost is additional to the purchase price of the machine.
  13. What electrical supply is required?
    220V single phase, 15 Amp.
  14. How can spares be obtained?
    All products are designed using stock-standard electrical parts that are generally available from most good electrical supply outlets in the world. Relay switches, contactors, motors and other parts are interchangeable with generic equivalents. This is a deliberate design approach in order that products may be self-serviceable even in developing countries with poor service infrastructure. Spare parts can also be ordered directly from the factory in South Africa.
  15. How can I obtain samples?
    We receive a large volume of sample requests every month, often out of mere curiosity. If you wish to requests samples, please send your request by email. You may instruct your own couriers to collect. In this case, please confirm the collection date with us first and provide an accurate physical delivery address with telephone number and full contact details.
  16. What maintenance is required?
    Checking the oil level of the air compressor and keeping the machine clean is the only maintenance that is required. There is no other scheduled maintenance on this machine.
  17. How can spares be obtained?
    All products are designed using stock-standard electrical parts that are generally available from most good electrical supply outlets in the world. Relay switches, contactors, and other parts are interchangeable with generic equivalents. This is a deliberate design approach in order that products may be self-serviceable even in developing countries with poor service infrastructure. Spare parts can also be ordered directly from the factory in South Africa.
  18. What is the lead time and payment terms?
    Products are manufactured to order. Payment is 50% payment at order, the balance before shipment. Lead time is about 6 weeks from acceptance of order.
  19. How can I obtain a shipping quotation?
    Shipping quotation? Shipping quotations are provided by freight and logistics companies. There is time and work involved and in most cases only cost estimates are provided. To obtain a shipping estimate, these tips may be helpful.
