A rotational dobby for use with weaving machines having plural heddle frames. The dobby has an eccentric disk for each heddle frame arranged side-by-side on a drive shaft with a coupling wedge movably installed therein, which coupling wedge effects a coupling and uncoupling of the eccentric disk relative to two recesses which are diametrically arranged on the shaft. A connecting rod is provided on the outer circumference of the eccentric disk and is coupled directly or through a rocking lever to an operating rod connected in turn to the heddle frame. A control mechanism is provided with pressure fingers which are movable in response to an information pattern on a pattern card.
