Abstract
The invention relates to a weaving machine having plural heddle frames, into which heddles are threaded with a free floating characteristic or operational clearance onto thread rails. The heddles are arranged on the thread rails with the least possibility of movement and without a free floating capability during a portion of the heddle frame movement and with a free floating characteristic during the rest of the movement of the heddle frame to facilitate a self-alignment of the heddles with the warp threads. The free floating characteristic is initiated by periodically reducing the distance between the two thread rails.
Claims8
A weaving machine having a shed forming means thereon comprising:
- frame means;
- a heddle frame movably supported on said frame means;
- first and second spaced and parallel thread rail means mounted on said heddle frame;
- at least one heddle connected to and extending between said first and second thread rail means;
- first means for effecting a change in the spacing between said first and second thread rail means in response to a movement of said heddle frame, said first means including control means, separate from said shed forming means, secured to said frame means for controlling the relative spacing between said first and second thread rail means;
- and
- connecting means for operatively connecting said control means to one of said first and second thread rail means for causing said one of said first and second thread rail means to move selectively at least one of toward and away from the other of said first and second thread rail means in response to said movement of said heddle frame.
