<High-speed damper mechanism>
Plate spring
When pulse motors are used for high-speed drive control, vibration inevitably occurs. This new
mechanism uses a spring plate to absorb the inertial reaction force generated during high-speed
operation quickly and efficiently. The new electronic zigzag mechanism allows sewing at high
speed with no pattern distortion.
