Latest Patents

Zenke's latest patents showcase his expertise in efficiently producing fiber-reinforced thermoplastic resin tape. One notable invention involves a process and apparatus designed to prevent fiber cutting at the onset of production. This process includes a resin impregnation step, where a fiber bundle is opened and impregnated with molten thermoplastic resin. Moreover, Zenke's technique involves passing the impregnated fiber bundle through a slit in a nozzle, where he sets an initial gap dimension larger than usual before adjusting it to normal dimensions once production conditions are met.

Another important patent focuses on connecting reinforcing fiber bundles effectively. This method uses pressurized air to intertwine the tail end of a preceding wound body’s fiber bundle with the front end of a new wound body’s fiber bundle. A critical preparation step ensures that the amount of sizing agent in both sections is kept at or below 4 wt %, allowing for a seamless connection between the two fiber bundles. Additionally, he developed a method for producing long fiber reinforced thermoplastic resin pellets, showcasing his versatility and innovation in the field.
