In a system in which cops having yarn wound around hollow core bobbins are conveyed on carriers, a device for readying a starting end of said yarn for delivery to a winder comprising:
- cop hanging means for removing each of said cops from its respective carrier and refitting said cop onto said carrier;
- starting yarn end unwinding and cutting means for unwinding said starting yarn end from said cop and cutting said unwound starting yarn end,
- tangled yarn cutting means for separating said starting yarn end from said yarn wound on said cop;
- and
- yarn end inserting means for inserting said starting yarn end into the hollow core of said bobbin;
- wherein said starting yarn end unwinding and cutting means, said tangled yarn cutting means and said yarn end inserting means are arranged sequentially.
In a system in which cops comprising yarn wound around hollow core bobbins are transported on individual carriers, a device for readying a yarn end for delivery to a winder comprising:
- cop removing means for removing said cops from their respective carriers,
- yarn end unwinding means for unwinding said yarn end from said yarn wound around said bobbin,
- yarn end disentangling means for disentangling said unwound yarn end from said yarn wound around said bobbin,
- yarn end cutting means for cutting said yarn end to a length such that said yarn end will not interfere with said carrier upon insertion of said yarn end into said hollow core of said bobbin,
- yarn end inserting means for inserting said cut yarn end into said hollow core of said bobbin, and
- cop refitting means for refitting each of said cops onto its respective carrier.
