Title: Erkki Leinonen: Innovator in Calender Technology
Introduction
Erkki Leinonen is a notable inventor based in Järvenpää, Finland. He has made significant contributions to the field of calender technology, holding a total of four patents. His work focuses on improving the efficiency and effectiveness of multi-nip calenders used in various industrial applications.
Latest Patents
Leinonen's latest patents include a method and arrangement for computing and regulating the distribution of a linear load in a multi-nip calender. This innovative approach involves passing a material web through a set of rolls, which includes variable-crown upper and lower rolls, along with intermediate rolls. The design ensures that the bending lines of the rolls are curved downwards when the nips are closed. By taking into account various physical properties affecting the bending of each intermediate roll, such as bending rigidity and mass, Leinonen's method regulates the linear loads to maintain equilibrium and a predetermined state of deflection.
Another significant patent by Leinonen is for making a powder metal roll end for a heatable roll. This roll end is particularly useful in paper or board machines and is manufactured using a powder metallurgy process. The process includes forming a duct system for a heat transfer medium, utilizing hot isostatic pressing to achieve optimal results.
