AI Technical Summary
In the current garment sewing process, sewing multiple decorative strips or adjusting their positions is complicated, affecting sewing efficiency and quality. In particular, it is difficult to ensure that the decorative strips are aligned with the cut pieces and cover the gaps when sewing the edges of the garment pieces.
A presser foot stop fastener was designed, comprising an adjustment mechanism and a limiting plate. The adjustment mechanism moves the presser plate through a wedge, a push plate, and a knob. The limiting plate restricts the movement of the decorative strip along the seam length, ensuring that the decorative strip fits the cut piece and its position is adjusted.
It improves sewing quality, ensures that the decorative strip is aligned with the cut piece, avoids the tight connection between the presser and the cut piece which would cause inconvenience in movement, and improves the controllability of the cut piece movement.
