Latest Patents

Klerelid's latest patents include a method for creating a parent roll for tissue paper. This invention allows for a uniformly wound parent roll of soft, high bulk tissue, which exhibits greater uniformity in sheet basis weight, machine direction stretch, and bulk compared to conventional methods. The process involves using a relatively air impermeable transfer belt that traverses an unsupported span between two winding drums. The tissue sheet is transferred from the transfer belt to the parent roll while maintaining controlled tension and deflection.

Another significant patent is an apparatus and method for winding tissue webs into a parent roll. This invention also results in improved uniformity in sheet properties throughout the roll. The apparatus engages the tissue web against a reel spool with a flexible member, allowing for precise control of the winding process and the application of light nip pressure.
