Latest Patents

One of his latest patents is a fully automatic method for handling yarn knots in a continuous flat knitting process. This method includes several steps: a knot alarm detects knots and triggers an alarm; the machine automatically loads and runs a preset knot handling program; it pulls out the yarn segment containing the knot from the knitting area and secures the knot; the machine reinserts the subsequent yarn back into the knitting area, returning to the knitting position before the alarm; and finally, it cuts off the excess yarn segment containing the knot and continues knitting. This process utilizes a knot alarm set on the flat knitting machine to automatically detect knots on the yarn in advance. Once a knot is detected, the yarn segment containing the knot is pulled out and cut off, thereby removing the knot while hiding the yarn breaks and preventing yarn ladder.

Another notable patent is for a yarn carrier device with a yarn tension control function for flat knitting machines, along with a corresponding yarn tension control method. This application relates to a yarn carrier device that adjusts yarn tension. When a carriage is connected to the yarn carrier device, a fixing frame carrying a bobbin ascends or descends on sliding rails installed on the device. The speed, time, and distance of the fixing frame's movement can be calculated based on the yarn carrier's stop, the quantity of unknitted yarn, and the carriage's speed. This innovation allows for precise control of yarn tension during the knitting process.
