"The state-of-the-art bookbinding is mainly performed with hotmelt and PUR polyurethane.
The core problem of hotmelt bindings is that the whole process chain has to be heated up to 130-200 °C. The hotmelt process has high energy and CO2 consumes, the toxic and partly carcinogenic fumes of the hotmelt process damage the employees’ health. Hotmelt is more expensive in terms of energy, labour, cleaning costs and additional equipment, too. Finally, hotmelt therefore harms the environment.
Ribler from Stuttgart as first mover has developed cold glues and further five components of a patented binding technology for books and paper blocks. With ""Ribler Technology"" on the other hand, the products are bonded at room temperatures almost without energy. Energy and CO2 consumption are reduced by 80%, glue consumption is reduced by 80% and paper consumption by 5%. Thus, the hotmelt production costs exceed our cold glue process costs by up to 30%. Ribler Technology is fully environmental friendly. And Ribler bound books do not have a clinging effect when opened, but remain perfectly lay flat and open.
The Ribler binding machines will contribute to environmental relieves, improve working conditions for the employees and will help bookbinding companies gain more proftitability and stability. This potential is relevant for an estimated number of 1,500 perfect binders, workers and companies in Germany and a number of 7,350 in (Western) Europe and 24,500 worldwide."
