Latest Patents

Kawase's latest patents include an automatic fabric density adjusting device and a yarn feeding control mechanism for a circular knitting machine. The automatic fabric-density adjusting device features a detecting device that monitors the rotary movement of a knitting machine. It includes a driving mechanism that operates a yarn positive feeding device based on signals from the detecting device. Additionally, it has a controller that regulates the driving mechanism to ensure the yarn feeding device supplies the necessary yarn volume for the desired fabric. A fabric tension sensor is also integrated to detect variations in knit fabric tension, allowing the controller to adjust the fabric take-up accordingly.

The yarn-feeding control device comprises several knitting needles and a yarn-feeding device that supplies knitting yarn via a yarn carrier. It also includes a cylinder housing the knitting needles, a cam holder equipped with a control cam for the knitting needles, and a cam ring supporting the cam holder. A yarn tension sensor determines variations in tension and signals the controller to adjust the knit stitch volume.

Another significant patent is an apparatus and method for controlling a selectable knitting machine. This apparatus is designed for mechanisms such as needle selection or yarn feed changeover in knitting machines. It includes sensors that detect the rotational speed of the knitting machine component and generate periodic signals. A control mechanism works with the sensor to produce control signals responsive to predetermined trigger points of the periodic signal, allowing for adjustments based on the rotational speed of the knitting machine.
