Fully automatic method for handling yarn knots in a continuous flat knitting process

A continuous flat knitting method for automatic processing of knots, comprising the following steps:

• Step 1:
• setting a knot alarm on a flat knitting machine, the knot alarm detecting a knot in a yarn segment of a knitted yarn, wherein the yarn segment comprises a knot part and the knot part comprises the knot, and the knot alarm emitting a signal;
• Step 2:
• the flat knitting machine automatically loading and running a preset knot handling program;
• Step 3:
• the flat knitting machine pulling the yarn segment out of a knitting area and fixing the knot part under control of the knot handling program;
• Step 4:
• under the control of the knot handling program, the flat knitting machine inserting a subsequent yarn section of the same knitted yarn that has been pulled out of the knitting area into the knitting area, until the subsequent yarn section is inserted to a knitting position before the alarm was triggered;
• Step 5:
• under the control of the knot part handling program, the flat knitting machine trimming off an excess yarn portion that contains the knot part and continuing knitting until a fabric is fully formed, wherein the excess yarn portion is an excess yarn portion of the yarn segment that has been pulled out of the knitting area;
• wherein actions controlled by the knot handling program also include a first anti-ladder action when pulling out the yarn segment from the knitting area and a second anti-ladder action when inserting the yarn into the knitting area, wherein
• when pulling out the yarn segment from the knitting area, the first anti-ladder action involves alternating floats with tucks, the yarn segment is secured by using an electronically controlled clip set on the flat knitting machine to clamp the yarn near the knot part;
• when inserting the yarn into the knitting area, the flat knitting machine performing the second anti-ladder action by alternating floats with tucks until the yarn is inserted back to the knitting position before the alarm was triggered.
