Round point with small triangular tip "SD1" or "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.
Applications / Highlights:
- 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
- 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
