ABSTRACT:
A combination yarn processing machine and overhead creel assembly comprising a machine mounted overhead creel assembly including a bobbin carriage which pivots about an axis mounted on a framework above the yarn processing machine. The bobbin carriage pivots through a circular arc between an up position substantially above and over the processing machine and a down position substantially above and beside the machine without substantially changing the length of the yarn extending between creel bobbins or other yarn packages in the bobbin carriage and the processing machine and is loaded and unloaded to replace empty yarn packages while the processing machine is in operation drawing yarn from still laden yarn packages on the same bobbin carriage. A spring loaded counterbalancing system holds the bobbin carriage in the up position and in the down position and aids in minimizing the effort expended by operators servicing the machine while moving the bobbin carriage between the up and down position.
