Creeling: Creeling is the placement of full packages in position ready to be unwound as part of the transfer operations. An alternative meaning is the removal of the exhausted packages & their replacement with full ones.

Piecing: Piecing is the finding & connecting of the ends on the packages. The connection between the ends can be made by knotting adhesion or welding but the former is by far the most common. Such connections are required whenever an end breaks or when a creeling operation has been completed.

Doffing: Doffing is the removal of newly wound packages & the replacement of these by empty packages which will receive yarn during the transfer process. It will be noted that creel packages are emptied as the packages to be doffed are filled.
