摘要： The first object of the present invention is to provide a traverse device (1) wherein a traverse guide (41) can be transferred at high speed by detecting the position or the speed of the traverse guide precisely. The second object of the present invention is to provide a traverse device capable of changing the turning position easily without using complicated mechanism and of accomplishing the speeding up of the traverse without carrying out the rotation of the electric motor in both forward and backward directions. According to the present invention, the traverse device (1) for traversing the yarn guided by a traverse guide (41) comprises a plurality of piezoelectric elements (2a, 2b, 2c ....) arranged in the traverse direction over the entire traverse range where the yarn is to be traversed, an elastic body (3) deforming by the strain of the piezoelectric elements, and an alternately moving body (4) transferring in the traverse direction by the strain of the elastic body (3), provided in the elastic body (3) capable of transferring in the traverse direction, without being displaced from the elastic body substantially. The traverse guide (41) transfers in the traverse direction accompanying the transferring of the alternately moving body (4) (Fig. 1).

摘要： A piezoelectric inertia actuator is disclosed herein, which includes an actuator body, a coupling body defining a receiver, a lock body positioned within the receiver, and a piezo body attached to the coupling body. At least one flexible frame configured to support an engaging body may extend from the piezo body. A spring blade configured to apply a preload force to the engaging body via a decoupling preload body may extend from the coupling body. A tension member may be positioned within the lock body and apply a preload force to the piezo body, thereby creating a net compressive stress therein. The piezoelectric inertia actuator may further include a piezo preload body configured to apply a reaction force to the piezo body in order to maintain the compressive stress therein. The preload applied to the piezo body may be substantially decoupled from the preload applied to the engaging body.
