We have created a more efficient method of core gluing. Our technique restores the cores to homogeneous units with optimum strength. This gluing process has become increasingly common, as the reuse of cores results in cost savings, improved working conditions as well as reduced environmental impact. Efficient core gluing can be integrated into a paper mill process and customized in various ways, depending on the requirements and prerequisites. This technique is one example of how Core Link utilizes its long-term experience creating new methods that increase productivity in the paper industry.
