The flat silk drawing machine this aircraft is makes the packing to prepare with the plastic cylinder knitting build, uses gathers third thin, the polythene and so on gathers a thin hydrocarbon compound flat silk knitting full circle tubular to arrange the weaving, after earnest, the membrana tectoria, sutures and so on, but makes each kind of specification the grain, the bread flour, the feed, the sugar, the table salt, the chemical fertilizer, the cement, packing and so on mineral use the bag, may also carry on broken to launch the membrana tectoria manufacture rainproof canvas. 　　This aircraft quotes the overseas advanced type, unifies our country national condition and the user opinion improvement design manufacture becomes, has the craft to be advanced, the equipment is reasonable, the interchangeability is high, merits and so on service convenience. Because and its applicable scope is broad, the operation, the adjustment is simple, but is uninterrupted; The continuous production, the efficiency is high, consumes low and the depth is welcome the user community.
