Abstract (en)
[origin: US4458727A] Two rotation heddle frame units pivotally engage the respective ends of a differential lever, which units move the center of the differential lever in a patternlike manner between three different positions. The movement of the center of the differential lever is transmitted, through a rocking lever, onto a plate which, in spite of the three different lever positions, moves an angle lever and thus the heddle frame into only two positions, namely, the upper and lower shed positions. The heddle frame moves without any intermediate stop between its two end positions. Since each lifting unit stands still during the operating movement of the other unit, this standstill time, together with the duration of a possible shed standstill of the weaving machine, is available for actuating the lifting unit, and a higher weaving speed is thus possible.
