Yarn conveying system

A yarn-conveying system comprising:

• a first closed loop including a cop conveying sub passage transporting cops from a yarn spinner to a winding machine and a bobbin conveying sub passage transporting empty bobbins from the winding machine to the yarn spinner;
• and
• a second closed loop including a defined yarn package and spool conveying sub passage transporting yarn packages and empty spools between the winding machine and at least one weaving machine, wherein yarn formed by the spinner is directly conveyed to an associated winding machine and associated weaving machines;
• wherein said first closed loop comprises:
• means for preparing cops for the winding machine;
• a first conveying passage transporting cops and bobbins from individual spinner units of the spinner to the cop preparing means;
• a second conveying passage transporting cops from the cop preparing means to individual winder units of the winding machine;
• first means for separating out bobbins, returning from the individual winder units, having a predetermined first minimum amount of yarn;
• a third conveying passage transporting bobbins from the individual winder units to the first bobbin separating means;
• a fourth conveying passage transporting bobbins from the first bobbin separating means to the individual spinner units of the spinner;
• means, disposed adjacent the cop preparing means, for distinguishing cops from bobbins and transporting bobbins to the fourth conveying passage;
• and
• second means, disposed adjacent the first bobbin separating means, for separating bobbins, returning from the individual winder units, having a pre-determined second minimum amount of yarn and transporting these bobbins to the cop preparing means.
