Abstract
The aim of the study was designed and invented a processer for manufacturing reinforced-geogrids. The Reinforced geogrids manufactured by the processer was applied to geotextiles. The priority of this study was the shedding mechanism with twist warping. The results showed that the processer of reinforced-geogrids could manufacture reinforced-geogrids su ccessfully.

First, Chinese summary
Research this purpose lie in design and make one not to can use on is it put more energy into graticule mesh ground processing organization, worker of fabric to make, so as whom new-type loom weave put more energy into graticule mesh fabric apply ground worker at the fabric. It is to be the who lies in loom to open one's mouth organization by entangling been in focal points in this research by way pass sending off, make warp and woof form twist together each other connect joint, in order to make Cheng is it put more energy into worker of graticule mesh ground fabric to suitable for. Result show, graticule mesh of putting more energy into made in the research this worker fabric process organization can is it is it put more energy into graticule mesh ground organization, worker of fabric design to produce to succeed in already.

Two, brief introduction
Ground worker's synthetic ( Geosynthetics) Development have already nearly half century, but new product weed out the old and bring forth the new constantly still, space that can develop a suitable one heavy also. The ground worker puts more energy into the graticule mesh, as Fig. 1 shows, it is one of them of the ground worker's synthetic. The use of the fabrics in the earth project, develop very fast putting more energy into the graticule mesh for the ground worker in Taiwan, its definition is: Have rule netted structure made up of tension components, have enough network eye make around soil, rock or Engineer technology relevant materials are run through during that time otherly, reach the anchor and make the function with strength. Have already widely used to put more energy into and block the soil strongly, the slope, weak soil layer are put more energy into, the road grade mixes the lower floor and puts more energy into etc. and puts more energy into the project by putting more energy into. The worker can roughly be divided into two big classes to put more energy into the graticule mesh at present: One kind is a hard type graticule mesh; Another kind is a soft graticule mesh. So-called and getting hard graticule mesh department is it extend again integrative shaping to punch with plastic membrane, or with plastics pieces of graticule mesh, spot welding of shaping, it is plastics but not weaving type; It is and soft graticule mesh it utilize not weaving technology having yarn woven not including not for material not othering after fabric not netted(for example, PVC, pitch, emulsion,etc.) And succeed.
Person who weave cotton cloth put more energy into worker of graticule mesh ground fabric can is it put more energy into for knitting type worker of graticule mesh ground fabric and shuttleless loom person who knit put more energy into worker of graticule mesh ground fabric to divide into. The knitting type puts more energy into graticule mesh the Engineer fabric usually uses and draws the oblique tricot machine ( Raschel Loom) Wove it; Shuttleless loom person who knit put more energy into worker of graticule mesh ground fabric use light steel shuttleless loom loom ( Gripper Loom) , or sword belt type loom ( Rapier Loom) Weave. Whether shuttleless loom person who put more energy into graticule mesh worker fabric of knitting etc. for the following odd kinds of design. ( 1) Interweave and click and take square flat organization as the core, and on is it wind the line to place way is it order it regular to interweave, as Fig. two shows to utilize; ( 2) Isreal side is flat to organize the way to interweave into a graticule mesh, and then in the graticule mesh, go to both sides to construct and deal with PE membrane, is it live in PE membrane, network of eye excise to hide with person who washes hole finally, as Fig. three shows; ( 3) The graticule mesh interweaves in the way for plain weave, twill, satin weave, or other changes organization, is it cover one PE membrane to have all upper and more lower, lay first PE weave cotton cloth in graticule mesh and PE membrane among them, is it live in network purpose part excise to hide with person who washes hole finally, as Fig. four shows.
The designers of this research institute, make the warp and woof type form close making the joint by way of entangling by the opening, interweave kind structure not can improve shuttleless loom the knitting types last graticule meshing form worker fabric there aren't intensity connecting.
Three, design principle
3.1 Put more energy into the ground engineering fabric processing machine of graticule mesh
Person who put more energy into graticule mesh as Fig. five shows worker organization, fabric of processing machine.
3.2 Send and pass sports
It gives to be to is it on warp shelf, coil at the warp beam to put tube yarn by sporting in the research this, its mainly is put more energy into by graticule mesh fabric latitude to having not suring from interval, in it gives to be comparatively difficult on design of organization, adopt tube yarn shelf as is it pass device to see off. Six of Fig. show for side view, warp of shelf, insert yarn spindle fix on post, slope 15¡ã downwards. The yarn draws on 1 top from the tube, after crossing 3 tension devices, guide it to the front.
3.3 The comprehensive frame is designed
On the loom, the warp is controlled by the comprehensive silk, a lot of comprehensive silks that the warp which controls the whole width interweaved, installed in the frame. Produce a certain fabric what organization need one group comprehensive frame is it form a complete set the comprehensive frame to call, the size of the comprehensive frame is:
( 1) The total length of the comprehensive frame appearance: Namely the range of slice of warp that this size should follow the working range of the comprehensive frame, fix more accurately.
( 2) The thickness of slice of the comprehensive frame both sides board: Interval of the comprehensive frame while putting that it is usually mean opening one's mouth.
There can't be too big deformation in the comprehensive frame while weaving, can't also produce too big vibration, so there must be quite good rigidity in the comprehensive frame.
3.4 Is it is it design to open one's mouth by way to entangle
Of the this research, sports are to form the opening by entangling by the comprehensive silk to open one's mouth. As Fig. seven shows, act as the yarn ( A) With the yarn ( B) With the comprehensive silk, leave while moving, yarn ( A) With the yarn ( B) The interlocking of the upset appears, and not woof it is by entangling by way transform into it if interweaving, order, different from by the loom not general one, laid parallel to interlock there aren't one that transform into.
Fourth, result and discussing
4.1 Tension controlling
In order to can control the size of tension while weaving, making tension steady and unanimous, we use the warp shelf to send to pass sports. Because the yarn draws from regular toper tube, so it retreats and moves round tension more even. Because all tubes are returned and moved round the diameter the same and having adjustable tension devicesly, so a slice of yarn tension of the warp is more even. The tension device that we use is the tension slice ( Tension washer) ,As Fig. eight shows, tension stretch is it control tension of warp to come with several metal slice or plastics slice.
4.2 Entangle and pass the fabric
In this research, use and entangle to pass the comprehensive silk, on making, is it interlock to leave, throw into and woof must entangle and pass the fabric at opening, as Fig. nine shows. Kind knit not can increase graticule mesh of putting more energy into of lawing connect intensity of forming of worker fabric, and then improve the brute force of the fabric.
Fifth, conclusion
Graticule mesh of putting more energy into that research institute design this worker fabric process organization can is it produce the Engineer graticule mesh fabric is organized qualifiedly to weave already. It will be in the direction of weaving different yarn kind, not organizing with the fabric etc. in the future, Engineer fabric process organization high brute force put more energy into graticule mesh, expect to be able to develop and put more energy into new cloth kind with better result.
