Automatic shedding mechanism

An electronically controlled sectional warping machine in which a warping process is performed by dividing all the warping yarns for fabric into a certain number of bands, by passing warping yarns supplied from a creel for one band through a closed reed and a space deciding reed, by reeling warping yarns around a warping drum at the necessary density and to the necessary length, so that warping is done for the desired number of warping yarns and to the desired warping width;

• said electronically controlled sectional warping machine comprising:
• (a) a warping drum which stops rotating when it reaches the predetermined position;
• (b) closed reeds for forming lease by dividing warping yarns from said creel into upper and lower yarns;
• (c) a space deciding reed moved back and forth by a driving mechanism so as to decide the spacing of the warping yarns;
• (d) lease rods going into lease formed by said closed reeds and moving upward so as to keep the lease;
• (e) a plurality of lease tapes which are let off to the surface of said warping drum via a lease tape guide so as to maintain the lease while going through the lease;
• (f) a reel which is disposed on a side of said warping drum so as to take in said lease tapes and includes means for reeling said lease tapes;
• and
• (g) a movable unit which is moved back and forth by the electronically controlled driving means so as to let off and rewinding said lease tapes.
