Method of conveying production with high strength canvas and equipment selection

Conveyor belt, canvas production is widely used in DORNIER rigid rapier loom is the best model to produce the high strength canvas. In the production of heavy fabric has two big problems, namely the weft yarn fineness of 10000 dtex thick fabric weft insertion and beating up force. Because the DORNIER rigid rapier with active clamping and transfer way of weft, weft fineness can reach 30000 dtex, at the same time, it adopts the double conjugate cam weft, loom has generally incomparable beating up force. The DORNIER loom production of heavy-duty conveyor belt, the conveyor belt similarly so, DORNIER in this respect has accumulated rich experience. The loom can choose PTV2/S6 190 cm PTV2/S 6300 cm single weave or double weave.

(1) diameter straight weft fabric

The stress layer warp creel on take-off from weaving, this is because the warp is too thick, and the beam can be wound length is limited, beam diameter of 1000mm can be wound length is generally only about 600m. If the beam weaving will affect the loom efficiency and consumption increase caused by the warp. The system uses an electronic loom warp let off system. The binding warp beam weaving is, if there is no warping machine is also available from the bobbin rack yarn, by the addition of an electronic let off control system.

(2) the double fabric

The double fabric can generally be yarn directly from the creel, no significant difference from the ordinary canvas production, only the woven fabric is more complex, at the same time warp density is high, need to adopt the dobby shedding mechanism and comb the shuttle.

Configuration of electronic dobby shedding mechanism can greatly improve the flexibility of production loom, some complex organization, at the same time as a result of such high strength canvas particularly high yields, using DORNIER loom, the average daily output of more than 3T. If the weaving loom twin 2800, then the output loom can reach 4T. If the machine is idle time, also can be used for the production of dam cloth heavy canvas and 2/2 broken twill texture impact dipped canvas and all levels of EP and NN canvas canvas.
