Products Description
Computer Operated Sewing Machine GW-168-D / GW-668-D
Our computer operated sewing machine (GW-168-D / GW-668-D) produces a double lock stitch and is suitable for sneakers, casual shoes and other special materials. The machine features a light rocker for easy operation and an oiled system that protects the oxhorn, keeping the machine running smoothly through continuous production shifts.
The machine uses an innovative gear transmission structure that replaces the traditional chain drive. This design eliminates the common problem of chain elongation after a period of use, so the transmission of the hook line part is more stable and more accurate over the long term. The divided rotating structure automatically cuts off power and stops when gripping, protecting the machine from damage.
The split-type casing design makes it easier and faster to adjust the machine when changing the needle thickness model. The presser is controlled by computer with automatic fixing, and the revolution can be set according to the operator's needs - up to a maximum of 2000 circles per minute.
