Latest Patents
One of Harada's latest patents is a "Method and apparatus for cleaning printing cylinder." This invention relates to a novel method and apparatus designed to clean off ink sediment and paper powder that adhere to a cylinder, such as a blanket cylinder in a printing machine, without the use of any cleaning solution. The invention features a brush roll that is rotated by an independent driving source, which contacts the blanket cylinder during printing. The brush roll is equipped with many brush fibers that are bent at the ends to provide a combing function, achieved by bending the fibers in zigzags. The invention also specifies that the rotational directions of the blanket cylinder and the printing cylinder should be opposite, with a relative speed set between 5 to 12 m/s. Additionally, the dry brush roll is enclosed in a casing that includes a scraper for dust removal and a dust collecting portion, or it can be connected to a negative pressure system for easy dust handling.
Another significant patent by Harada is the "Washing method and apparatus for guide rollers of rotary press." This invention involves operating a rotary press slowly while feeding paper. A washing liquid is applied to the printing paper to wet it, and a series of guide rollers in contact with the paper are rotated at a different peripheral speed to wipe off contamination. The washing apparatus includes multiple guide roller driving devices that allow for this differential speed rotation.
