Latest Patents

One of Tanaka's latest patents is a method of piecing a yarn in an open-end spinning machine. This method involves stopping the yarn piecing machine in front of a spinning unit that has experienced a yarn breakage. The process includes reversing a package with a rewinding roller to rewind a yarn, cutting off the yarn to create a yarn end of predetermined length, and moving the yarn end to a position above the outlet of a withdrawal tube in the spinning unit. The yarn end is then fed through the withdrawal tube to a fiber collecting surface of a spinning rotor, where it is pieced to a sliver supplied by a feed roller. The pieced yarn is continuously drawn from the spinning rotor and moved to a position between a presser roller and a draw-off roller, which are adjustable in speed based on the yarn number count used during the piecing process.

Another significant patent is a method of transferring yarn packages. This method involves moving oppositely but randomly oriented yarn packages from a spinning machine to a subsequent operation. The process includes using a conveyor to deposit a package onto a package turning means, sensing the orientation of the package, and turning the package to ensure all sequential packages are removed facing the same direction.
