Abstract (en)

[origin: EP0299553A1] A clamp for gripping a thread is based on use of piezoelectric element(s) so that deflection of the element by a sustained potential difference maintains a clearance for free passage of the thread but a redn. of the voltage to one or more lower levels cause the thread to be gripped by one or more levels of force accordingly. The opposing member may be a static block or another piezoelectric element.
