Title: Innovations by Katsumi Ogawa in Fiber-Reinforced Resin Technology
Introduction
Katsumi Ogawa is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of manufacturing apparatuses for fiber-reinforced resin strands. With a total of 8 patents to his name, Ogawa's work has advanced the efficiency and durability of manufacturing processes in this area.
Latest Patents
One of Ogawa's latest patents involves a manufacturing apparatus for fiber-reinforced resin strands. This apparatus includes spreaders that effectively spread a reinforcing fiber bundle and are integrated within a crosshead. The crosshead continuously receives molten resin material from an extruding machine. Additionally, twisting rollers are positioned downstream from the exit nozzle of the crosshead. These rollers pultrude a fiber-reinforced resin strand formed from a resin-impregnated fiber bundle while imparting twists. Furthermore, twist retaining rollers are also located downstream to maintain the twists of the fiber-reinforced resin strand. Notably, both the twisting rollers and twist retaining rollers are constructed from metal with asperities on their surfaces, enhancing durability and enabling high production rates without slipping.
Another innovative patent by Ogawa focuses on a manufacturing apparatus that features a roller offset angle adjusting device. This device allows for easy adjustment of the roller offset angles of a pair of twisting rollers. The structure is designed to be simple, enabling the adjustment of the offset angle of the first twisting roller by merely rotating a first shaft roller support member. Similarly, the second twisting roller's offset angle can be adjusted through a straightforward mechanism.
