SpineCoat

The SpineCoat coating head was specially designed for book spine gluing. A powerful PUR application head for minimum, but reliable and reproducible adhesive application. Thanks to the characteristics of PUR adhesives compared to thermoplastic adhesives, a high binding quality can be achieved with significantly less adhesive and good lay-flat characteristics ensured.

The SpineCoat application systems are used for adhesive binding using PUR for small, medium, and large binding machines. They are closed systems and consist of a PUR melter (RobaPUR 2 MOD, RobaPUR 35 MOD or RobaPUR 40 MOD) and the SpineCoat application unit. A dynamic or circulating system can be selected. The circulating system stands for highest quality and ensures a consistent, uniform adhesive application, even at high speeds. The SpineCoat coating head achieves a thin and uniform coating of 0.3 to 0.5 mm across the entire book block spine. As the complete system is designed for PUR hot melt adhesives, there is no need for cleaning during short production interruptions. The SpineCoat application system is ideally suited for retrofitting existing bookbinding machines. Easily adjustable brackets enable optimum positioning of the SpineCoat application unit towards the book spine. In addition to book spine gluing, Robatech also offers side gluing using the SideBead jetting head.
