(4) Note. Including herein is the forcible inserting or embedding of one preform into the plastic body of another preform even though the only reshaping is the displacement of material accompanying and resulting from the preform inserting, see subclass 517.

(5) Note. Overlapping or contacting pieces of dough (e.g., by coiling, twisting or lapping, etc.) are not included herein unless particular means are provided to reshape the contacting areas subsequent to assembly to effect a uniting thereof.
