DT 165-02 Automatic trouser J shape sewing machine

3.The replacement of the folding pusher plate is easier and more convenient through the dovetall groove structure.

1）J-Shape Specialization: Optimized for fly curves, producing neat and smooth stitches

2）One-Step Forming: Automatically completes feeding → positioning → sewing → stacking, no manual assistance required

3）Left-Right Symmetry: Ensures identical sewing trajectories for left and right fly pieces

4）High Efficiency: Sewing time per fly is only 8-12 seconds (depending on fly length)

5）Labor Saving: Replaces 3-4 skilled workers (marking, positioning, sewing, trimming)

6）Consistent Quality: Reduces quality issues like curve deviation and puckering caused by operator fatigue

3.How is the precision of the J-shape curve ensured? Can left and right pieces be perfectly symmetrical?

The machine uses servo motor drive + high-precision guides; the sewing trajectory is completely controlled by digital program, not mechanical cams. This means:

• 100% consistent curves on every piece

• Left and right pieces can be set as mirror images, ensuring finished product symmetry

• Curve smoothness reaches 0.1mm level

Compared to manual sewing, human-induced variations are completely eliminated.
