Abstract
The refiner plate of this invention has a pattern of interlocking or nested elements having a 'I's 'T's, 'S's, 'L's, 'F's, 'E's, or 'H's shape which form channels. The body of the elements forms the refiner bars which hold the fibers as they move between the refiner plates in a disk refiner. The pattern of elements retarded the flow of fibers while at the same time providing a large open area for steam to pass through the refiner disks. The segments making up the elements producing a refiner bar which is reinforced for higher strength. The shape of the elements has a increased edge length exposed to the flow of fibers.
