T-8450C T-8750C T-8420C T-8720C Twin needle lock stitcher A micro-adjustable type floating presser foot, which can be slightly lifted to set according to sewing materials, is equipped as standard. This device is ideal for controlling presser foot floating in materials that stretch easily and materials with long pile. Prevents birds nests Easy Gauge part replacement Stabilized motor stop position at the time of Cam adopted in the lateral position adjustment thread trimming reduces the bobbin racing. mechanism for the rotary hook base allows This prevents the birds nest. It is a big easy fine adjustments for clearance between advantage when sewing the light materials. needle and rotary hook point can easily be made, which greatly increases the efficiency of replacing gauge parts. Furthermore, a needle drop correction function (sideways) is provided, so that the needle drop position can still be adjusted to the center of the needle hole even if Model overview using commercially-available gauge parts.
