Try hydrating the tape and unwinding it slowly (by hand) to find any sticky 
spots. If you don't hydrate enough, or unwind too fast, you risk delamination. 

To rehydrate, put the tape in an enclosed chamber containing water on the 
bottom, and a raised surface (above the water) to place the tape. Leave the tape 
there for a while. If it still seems brittle, leave it for another while. Once 
it becomes supple to the touch, it is ready to work with.

Subject: [ARSCLIST] Pinning Acetate Tape

Hi Folks,

I have an acetate audiotape that is pinning (a term used in the Sound
Directions project). Basically, bits of oxide are sticking to adjacent
layers of tape and are thus removed from the substrate upon unwinding. Does
anyone know of a way to remedy this situation?

Thanks,
Alex Kroh
