I thought they used special tape- a bit like sellotape- which you placed
in
the spicer and it squeezed it down, trimmed it, etc. I half remember
seeing it done once or twice.


Oddly enough that was my memory too but I think I was confusing it with
magnetic tape splicing. Taping a film splice is going to mess with the
sprocket holes so I dont think it would work.

Professional film splicing does use tape because it is stronger than
solvent-welding of the film base. The tape is designed to be as near
invisible as possible and has sprocket holes punched in it (or else maybe
the splicing tool punches them).

To get completely invisible splices, cinema films and high-quality TV drama
use a technique called A/B roll editing, in which the shots are divided into
two alternate groups and assembled with black film in between. See
