Latest Patents
Kato's latest patents include a method and apparatus for stencil printing. This invention addresses the deformation of the printing drum in rotary stencil printing apparatuses, ensuring uniform printed images even under challenging conditions such as low temperatures and high-speed printing. The method involves winding a perforated stencil sheet around a cylindrical printing drum, which has an ink-permeable peripheral wall. During rotation, ink is supplied from inside the drum, and the printing paper is pressed against the drum's outer surface to transfer the ink through the stencil sheet. The drum's peripheral wall is designed to withstand a stress of 0.75 kgf/cm or more, allowing for effective printing with inks of varying viscosities.
Another significant patent involves a drum-type printer that features a mechanism for adjusting the transverse position of the printed image. This design allows the printing drum to be rotatable and adjustable, ensuring precise alignment of printed images.
