Title: POSITIVE SHEDDING DEVICE WITH " SHAFT-IN-SHAFT" AND DISCS ARRANGEMENT
Abstract:
The invention pertains to world's first link and disc type positive Shedding Device without Hook, Knife and rotor cam type arrangement, the swivel links and discs augment the operational speed as well as reliability. Furthermore the output levers are driven by world's first "shaft in shaft" arrangement for gaining freedom for using bigger, better and stronger parts, as the constraint in conventional devices comes from heald frame pitch limitation of 10 to 15 mm per frame. The invention breaks this design barrier and also comprises a sturdier, positive logic, electro- magnet actuated frame selector and equally positive frame execution mechanism. This invention also addresses world's first left hand side and right hand side, split structure of shedding device which occupies very little space on the weaving machine and paves way for making a weaving machine having a very small footprint, with half of heald frames driven from one side and remaining half from another.
