2.Rectangle

3.Saw-shape

1466Q

1.Triangle

•General sewing

2.Rectangle

•This is effective for preventing the material from getting stuck in the needle hole when sewing the rear tack, which can happen when using lightweight materials.

(An offset is used so that the stitches do not overlap when sewing the reverse zigzagging for the rear tack.)

*Reducing the number of front tack stitches is effective in preventing the material getting stuck at the front tack.

*Using a needle plate with a small needle hole (1.2) as well can also help in preventing the material from getting stuck.

3.Saw-shape

• This is effective for preventing dimples in the rear tack, without the need for underlay sewing.

*The number of stitches for the saw-shape type of sewing is set by means of parameter Nos. 38 and 39.
