ABSTRACT:
Accumulated deposits are removed from the face of a spinneret by periodically manually wiping the face of the spinneret with the blade of a hand held wipe stick. Cooling the blade just before use decreases the smearing of the polymer melt and increases the wipe cycle. Dry ice is the preferred cooling medium.
