Packing system for heat set

A method comprising:

• using a system comprising:
• at least one winder configured to wind yarn to form a yarn package;
• at least one sampling and tying machine that is configured to remove a portion of the yarn of the yarn package and tie off a free end of the yarn around the yarn package to inhibit the yarn package from unwinding;
• a dunnage supply area having therein at least one support structure for receiving a plurality of yarn packages thereon;
• at least one case assembly area;
• and
• a robotic arm configured to:
• move the yarn package from the at least one winder to the at least one sampling and tying machine;
• move the yarn package from the at least one sampling and tying machine to the at least one case assembly area;
• and
• stack the yarn package on a support structure in the at least one case assembly area,
• wherein using the system comprises
• winding, by the winder, yarn to form a yarn package;
• moving, by the robotic arm, the yarn package from the winder to the at least one sampling and tying machine;
• moving, by the robotic arm, the yarn package from the at least one sampling and tying machine to a first case assembly area of the at least one case assembly area;
• and
• stacking, by the robotic arm, the yarn package on a support structure in the first case assembly area.
