Step 4: it folds molding compound selvedge and is injected molten resin by middle seam extruder die head uniformly continuous, selvedge fastens It stitches and bonds in formation；

Step 5: it after seam compacting in molding cloth cylinder bonding, pulls apart as single bag webs；

Step 6: bag webs is collected.
