	The two halves of a split reel are held together by the threaded spindle in the center of the reel.

Care must be taken to ensure that the two halves of the reel are secure throughout use, and that the reel itself is in good repair.

They can also loosen and separate on a rewind table if rewinding is not done at a reasonable speed.


	It is also advised that you pay attention to the orientation of the split reel halves, so that when it is placed on a rewind spindle it is not rotating in a direction that will cause them to separate. This is unlikely to happen when rewinding film at a reasonable speed, but better safe than sorry.
