Latest Patents

Iwafune’s latest patents showcase his technical ingenuity and commitment to enhancing printing technology. One notable invention is the Offset Printing Machine, which features a plate carrier mechanism equipped with an endless plate belt and a blanket carrier mechanism with an endless blanket belt. This innovative design allows the blanket carrier mechanism to be conveniently displaced to either a pressure-contacting or a separating position relative to the plate carrier mechanism. The invention employs a geared rotation transmitting mechanism to ensure that the speed differences between the plate belt and blanket belt do not affect the printing quality, thereby preventing transfer shifts between the two.

Another significant patent is the Method of Producing a Blanket Belt for Use in a Printing Machine. This method involves several steps, including setting a reinforcement member onto a specifically designed mold, placing a green rubber sheet onto the reinforcement, and subsequently vulcanizing the assembly to construct an endless timing belt. This process effectively prevents expansion, contraction, and slippage of the blanket surface on the pulleys, enhancing the overall performance of the printing machine.
