Abstract
There is provided a device for either advancing or retracting the relative movement of a dobby with respect to the heddles of a weaving machine or with respect to any one or selected ones of such heddles. Thus, the shed-intersection point within said weaving machine may be advanced or retarded with respect to the dobby with resulting desirable modifications in the finished fabric. Same is accomplished by driving both the dobby and the heddle or heddles through a pair of levers and including a device by which the angle between said levers can be modified in order to modify the operational phase angle between such dobby and such heddle or heddles.
