When the plane of vibration is normal to the axis of the dispenser, the vibration will impart a rotary motion to the applicator. When the plane of vibration is parallel to the axis of the dispenser and normal to the direction of motion of the dispenser (such dispensers are usually robot mounted), a side-to-side or pendulum action is provided. When the dispense tip is provided with a static mixer to mix plural component materials, the vibrator will enhance the mixer's action.
