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.
Claims9
In a coupling device for controlling the sequential movement of the individual heddle frames of a weaving machine having a rotatable drive shaft, an eccentric ring mounted for free rotation relative to said drive shaft, catch ring means mounted on said rotatable shaft and for rotation therewith, connecting rod means having means defining an opening therein and adapted to rotatably receive said eccentric ring means therein, catch means radially movable toward and away from said catch ring means for effecting a selective connecting of said eccentric ring to said drive shaft and effecting a rotation of said eccentric ring with said drive shaft and a movement of said connecting rod in response to a driven rotation of said eccentric ring, the improvement comprising adjusting means for adjusting the moment in time in a cycle of operation of said machine that said connecting rod is moved.
