Abstract
A triaxial fabric weaving machine in which a plurality of elongate heddles for guiding warp yarns are arranged in weftwise rows and are shifted weftwise of the rows to thereby move the warp strands from one weftwise location to another. During weaving, heddles are supported by stationary guides and are moved longitudinally relative to the stationary guides for forming the warp strands into warp sheds in which wefts are inserted.
Claims12
A weaving machine for making triaxial fabrics comprising a plurality of elongate heddles arranged in weftwise rows for guiding warp strands, each of said heddles having cutout means therein adapted to be engaged for imparting longitudinal movement thereto;
- means for shifting said heddles weftwise;
- stationary means extending weftwise of the weaving machine for guidingly supporting said heddles in said weftwise rows;
- and means movable to and from extended and retracted positions relative to said stationary means and engaging said cutout means of said heddles for moving said heddles longitudinally of themselves across said stationary means to and from extended and retracted positions for forming warp strands guided thereby into warp sheds.
A weaving machine for making triaxial fabrics comprising a plurality of elongate heddles for guiding warp strands, each of said heddles having a nose portion with a warp strand guide opening therethrough and at least a medial portion with a longitudinal side edge and cutout means therein adapted to be engaged for imparting longitudinal movement thereto;
- stationary means extending weftwise of the weaving machine for guidingly engaging said medial portions of said heddles and for arranging said heddles in at least two weftwise rows;
- shedding bar means including first and second bars mounted adjacent said stationary means for respectively engaging said cutout means of heddles in a first row and said cutout means of heddles in a second row;
- and drive means for moving said shedding bar means relative to said stationary means for thereby moving said heddles longitudinally of themselves across said stationary means to and from extended and retracted open shed positions and forming warp strands guided thereby into warp sheds.
A weaving machine for making triaxial fabrics comprising a plurality of elongate strip material heddles for guiding warp strands, each of said heddles having a nose portion with a warp strand guide opening therethrough and a rear portion remote from said nose portion and with a hookshaped projection defining a laterally opening cutout therein;
- stationary means for engaging said heddles medially of said nose portions and said rear portions and for arranging said heddles in at least two substantially opposing weftwise rows;
- shedding bar means including first and second ribbed bars mounted adjacent said stationary means for respectively engaging said cutouts of heddles in a first row and said cutouts of heddles in a second row;
- means for moving said shedding bar means relative to said stationary means for thereby moving said heddles longitudinally to and from extended and retracted open shed positions and forming warp strands guided thereby into warp sheds;
- means for moving heddles weftwise relative to said stationary means in timed relation with movement of said shedding bar means and while said heddles are in retracted open shed position;
- and means for transferring heddles from one end of one of said ribbed bars to an adjacent end of the other of said ribbed bars.
