Application Description

La elección del mejor adhesivo para la encuadernación depende de muchos parámetros. Por ejemplo, de los requisitos y métodos de fabricación, pero también de la finalidad del producto impreso. Con un amplio abanico de adhesivos termofusibles y de dispersión, Jowat es el socio perfecto para la fabricación de libros, revistas y catálogos.

En Jowat ofrecemos diferentes soluciones adhesivas para la fijación de lomos y laterales de libros y catálogos de tapa blanda, así como para todas las calidades de papel estándar. La cola para los lomos de las tapas blandas está adaptada a los requisitos especiales de fabricación. Hay que tener en cuenta muchos factores para garantizar un rendimiento ideal del adhesivo, como la temperatura del adhesivo, el tiempo de permanencia en la unidad de procesamiento, la cantidad de aplicación y la velocidad de alimentación. Las colas laterales se utilizan para fijar las guardas de un libro o revista a la cubierta, y los requisitos que se exigen a estos productos también son altos. Una elevada flexibilidad, una adhesión perfecta en diferentes superficies, la no transferencia y una fuerza inicial máxima son factores esenciales para esta aplicación.

1. Spine glue
PUR / hot melts / dispersions / Two-Shot
After the book block has been milled on the back, the following step is to apply an adhesive film on the spine by nozzles or roller. For this process, several things must be considered to ensure a successful bonding result. Is the adhesive tank open? How high is the temperature? For how long will the adhesive remain molten? What application amount is needed and how high is the feed speed?

2. Side glue
Hot melts / dispersions / PUR
In general, the adhesive is applied by nozzle or roller on the first and on the last page of the book block, to bond it to the cover. The adhesive for this application has to be flexible, adhere to the most different surfaces and it should not bleed through, while providing maximum durability.
