SD1 · TRI TIP

This round point with a very small triangular incision cuts approx. 10 % of the stitch hole, 90 % is displaced by the conical round point "R". The result is a straight seam and a tidy seam appearance. The incision is smaller than with a cutting point.

Materials:

Fine leather · Clothing made of leather and imitation leather · Thin, synthetic leather materials · Materials coated with PVC/PUR, e.g. tarpaulins, tents, coated table cloths

Highlights:

The stitch appearance remains the same in all sewing directions when using multi-directional sewing techniques (programmable sewing machines). · Very gentle cut of the material

For precision sewing of fine leather or faux leather, plastic foils and other "difficult materials", the "SD1" – round point with small triangular tip – was developed. This point shape constitutes a compromise between a cutting point and a round point (displacement point). The small triangular cutting point at the extreme tip easily pierces the material (around 10 % to 15 %); the remaining 90 % is then opened up using the displacement principle of the round points. The result is a more accurate stitch placement and lower needle deflection than with use of a round point, plus a smaller incision than with use of a cutting point; in short, a straight, neat seam. A stitch density of around six to eight stitches/centimeter can be used.
