Book spine gluing – a clean binding that holds
Technology for the precise application of hot melt adhesive onto the spine and the side of the book block – PUR for the spine, EVA for side gluing. A strong binding with perfect lay-flat opening, lower adhesive consumption and a consistent result from the first book to the last. For bookbinderies, the printing industry and Book-on-Demand.

What you are dealing with
- An imperfect spine bond, poor book opening and loosening pages.
- Burning and degradation of the adhesive, deposits and frequent cleaning of the system.
- High adhesive consumption and downtime when changing format or order.
How Kaletech solves it
We supply technology for book spine gluing – precisely controlled application of hot melt adhesive onto both the spine and the side of the book block. PUR adhesive (high strength, resistance to heat and ageing) is used for the spine, and fine beads of EVA adhesive for side gluing. The result is a strong binding with perfect opening and consistent quality from the first book to the last.
Contactless application and melt-on-demand technology reduce burning and cleaning downtime. We integrate the system into new and existing bookbinding lines (retrofit), train operators and provide service. We will advise you on choosing a suitable adhesive.

Key benefits of book spine gluing with hot melt adhesive
Strong binding
High bond strength even with frequent opening of the book.
Perfect opening
The binding opens perfectly (lay-flat) and the book lies flat.
Adhesive savings
Precise metering reduces adhesive consumption – by up to half.
PUR for the spine, EVA for the sides
Reactive PUR for strength and durability, EVA for side gluing of the cover.
Consistent quality even at speed
A consistent bond from the first book to the last at a high rate.
Retrofit into lines
Easy integration into new and existing bookbinding lines.
How it works and what technology is used
Hot melt adhesive is applied by a jetting (slot) application head evenly onto the spine of the book block, or as fine beads onto the side to attach the cover in a single production step. Melt-on-demand technology melts the adhesive only as needed – reducing burning, deposits and consumption.
Preparing the book block
The spine of the block is milled and roughened so that the adhesive flows perfectly between the individual sheets.
Adhesive application onto the spine
The jetting head applies an even layer of PUR adhesive along the full length of the spine for a strong and durable bond.
Side gluing and fitting the cover
Fine beads of EVA adhesive on the side of the block attach the cover – all in a single production step.
A strong binding with lay-flat opening
A strong binding is created that opens perfectly and withstands heat and ageing.

Frequently asked questions
Reactive PUR adhesive gives the spine high strength and resistance to heat and ageing, which is why it is used on the spine (so-called PUR book binding). EVA adhesive is suited to side gluing of the cover. We will recommend the right combination according to the binding type and operation.
