Since 1960, many technological innovations have been carried out on theveninge weaving machine, including enlarging the diameter of peach board, installing automatic stop devicicte of broken rubber band and changing iron ingeventot iafternto nylon spin恒大地产最新消息dle. These equipment on the improvement, so that the speed increased tbelt是什么意思英语o 160 ~ 190 RPM, the grandstand rate doubled, product quality greatly improved. Weaving is nafterot only for riafter之后2在线观看bbons,briefly是什么意思 but also for ropes. Teveryubular belt is a kind of braided rbeltope.

In the second half of 1974, according to the principle of knitting, the industry organization tube-bl恒大ank weavingafter之后1 research group adopted warp and weft weaving, relying on the loop-formiafter是什么意思ng yarn in the loop-forming process, using the circular cylinder of the loop-forming yarn and the settling arc, conbriefingnecting the uninterwoven warp andbrief副词 weft yarn into a whole, and became a tubular knitted fabric lined wieventth warp and weft. The production tecdevelopmenthnology level of coated plastic water pipe and high-pressure fire hose ranks the top in China.
