Latest Patents

Martti Erkkila holds a patent for a method and device for jointing core ends. The invention relates to a method for end-to-end joining of paper roll cores into a continuous core master. The primary goal of this invention is to produce usable cores from those returned for recycling after use. In this method, the ends of core sections are reworked into complementary shapes required for a mating joint. Glue is applied to the complementary mating surfaces of the joint, and the core section ends are pushed in the axial direction, abutting each other while the glue sets. The invention also ensures that the cross-section of the cores is trued circular at least over the area of the joined core sections by applying a radially expansive trueing force on the joint. This radial trueing force is also advantageously employed for braking the axial travel of the core sections during the joining operation.
