Abstract
An actuator system for activating a latch needle, which latch needle has a shaft, comprising: a flat planar extension of said shaft having first and second parallel planar surfaces; at least one piezoelectric micromotor having a first surface region for transmitting motion to a moveable element, which first surface region is resiliently pressed to said first surface and at least one additional piezoelectric motor having a second surface region for transmitting motion to a moveable element which second surface region is resiliently pressed to said second surface; and wherein vibratory motions of said first and second surface regions apply forces to said flat extension that cause motion in said latch needle.
