Arranging opening time, back beam height, tension, opening Angle, drafting, reed-in reasonably were adopted in weaving process. These practice ensures no loop and enhance weaving efficiency.
To resolve the problems of inaccurate control of sizing speed, dry can temperature and beam winding tension of JSSJ-83 sample sizing machine, innovation of it was done.
