AI Technical Summary
Technical Problem
Existing double-needle overlock sewing machines produce a wide overlock width when sewing thick fleece-lined fabric edges, which causes the garment to rub against the skin and is costly.
Method used
By swapping the positions of the two needles, the main needle and the auxiliary needle can work simultaneously. The needle spacing is reduced through the dual-needle drive assembly, and a single-row double-thread sewing is adopted. The needle hole positions of the presser foot and needle plate are changed to reduce the width of the fabric binding seam.
Benefits of technology
The width of the fabric binding is reduced, making the garment more comfortable and reducing fabric waste and production costs.
