Latest Patents

One of Nagatsuka's latest patents is a method for spraying a chemical solution. This innovative technique involves spraying a chemical solution onto a canvas that has a loop shape in a side view. The method utilizes two nozzle devices that reciprocate at the same speed along a rail extending in the width direction of the canvas. The time period during which the canvas is in contact with wet paper is set to be 0.03 seconds or more. Additionally, the required time for the nozzle devices to move one-way ranges from 0.5 to 10 minutes, with a traveling speed of the canvas at 500 m/min or more. The length of the canvas varies from 20 to 80 meters, and the relationship between the number of times a point on the canvas contacts the wet paper and other parameters is defined by the equation N=(Tn·Vp)/K.

Another significant patent is for a canvas cleaning device, which aims to prevent the re-adhesion of stains while efficiently cleaning the canvas. This device features a base part that can slide along a rail, a cone part with a cylinder shape, and a high-pressure water spraying device installed inside the cone. An arm part extends from the base, equipped with a nozzle device that sprays high-pressure water onto the canvas.
