Definitions
- This invention relates to a method of recycling selvage warp yarns in a fabric weaving operation and an apparatus for carrying out the method.
- Background of the Invention Heretofore, the selvage warp yarns which bind the fill yarns during the weaving operation were slit from the fabric warp yarns and discarded.
- This invention reduces such a waste by recycling the warp yarns of the selvage. This is accomplished by using selvage warp yarns which are guided in a continuous pattern through the loom, returned through a spreader means to discard the cut fill fringe yarns and recombined to go through the loom again. Summary of the Invention
- a method of recycling selvage warp yarns in a weaving operation comprised of: a. providing a plurality of selvage warp yarns which form a continuous loop through the loom; b. feeding the selvage warp yarns next to an outer fabric warp yarn; c. weaving fill yarns through all of the warp yarns; d. slitting the fill yarns between the outer fabric warp yarn and the inner selvage warp yarn; e. passing the selvage warp yarns through a separator to allow the cut fill yarn fringe ends to dislodge from the selvage warp yarns; and f. recombining the selvage warp yarns to feed through the loom again.
- an apparatus for recycling the selvage warp yarns in a weaving operation comprising: a. means for guiding a plurality of continuous selvage warp yarns into a loom; b. a loom to weave the warp yarns with fill yarns into a fabric; c. a slitter means for slitting the fill yarns between an innermost selvage warp yarn and an outermost main fabric warp yarn; d. guide rollers to direct the cut selvage portion through a horn guide; e. a shaker bar to shake the cut fill fringe yarns from the continuous selvage warp yarns; and f. a spreader bar having spaced guides for each continuous selvage warp yarn to aid in dislodging the fill fringe yarn.
- FIGURE 1 is a schematic elevational view of the weaving operation of the invention.
- FIGURE 2 is a schematic plan view of the weaving operation of the invention.
- FIGURE 3 is an enlarged view of the splitting operation of the invention. Description of the Invention
- a fabric weaving system is shown generally at 10 where the main fabric warp yarns 12 are fed from creels 13 (FIGURE 2) along with the continuous selvage warp yarns 14 to the compression stand 16 into the loom 18 through guide rollers 20 under a dancer roll 22 which reciprocates vertically as shown by the double headed arrow to adjust the tension on the warp yarns.
- the warp yarns next pass through drop wires 24 which detect if any of the warp yarns are broken to halt the weaving operation.
- the warp yarns pass through the heddles 26 which raise and lower adjacent warp yarns or groups thereof to form the shed 25 wherethrough the fill yarns 27 are passed to form the weave .
- the reed 28 is a comb-like device that separates the warp yarns and also beats each succeeding fill yarn against that already woven.
- the thus woven fabric then passes past the slitter means 30 which slits the fill yarns 27 between the innermost continuous selvage yarn 14 and the outermost main fabric warn yarn 12. It is preferred that in weaving, a space of from 3 to 9 mm be left between the aforementioned yarns.
- the selvage is then separated over guide roller 33 from the main fabric where the main fabric is wound on wind-up roll 32 and the selvage is guided on roll 34 beneath the loom through horn guide 36 and onto spreader bar 41 which has spaced guides 42 which separate the continuous selvage warp yarns 14 to allow the fill fringe yarns 40 to be discharged from the continuous selvage warp yarns 14 with the help of shaker bar 38 which is attached to the dancer roll 22 with its up and down motion.
- the continuous selvage warp yarns are then converged over rollers 44 to pass through the loom again.
