  • Piezoelectric devices for yarn control apparatus in a textile machine
    Patent number: 5462097
    Abstract: A traction member (22) is connected to a yarn (6) which is to be controlled. A coupling assembly (38) serves for coupling the traction member (22) to a lifting device (32). A coupling assembly (38) contains a link pin (40), which can reciprocate between a neutral position and a coupling engaged position, with two piezoelectric switching members (50, 52) which function respectively alternately as actuator and sensor being allocated to said link pin 40. This results not only in a particularly simple coupling construction, rather also in a monitoring of the switching function of the coupling, wherein switching errors and switching malfunctions can be avoided.
