Claims5
In a weaving machine having a frame, a top leno warp beam and a bottom ground warp beam, and a positive-motion dobby, the combination comprising:
- easer-beam means overlying the top beam warp threads at the juncture of their vertical and their horizontal run;
- crank arm means mounting said easer-bar means to the frame for rocking movement toward and away from the top beam warp threads to respectively increase and decrease the tension in the top beam warp threads;
- and
- mechanical means devoid of spring means mounted to the frame and connecting said easer-bar mounting means to the dobby for positively rocking said easer bar toward and away from the top beam warp threads in response to predetermined movements of the dobby.
