clamp and cut off the end of the other film to be spliced. Each
clamp has sprocket
teeth in the channel in which the film rests
so that it is kept in the proper position for accurate joins.
Film is placed in the left-hand side, emulsion side up. The top
is then closed and the end trimmed by closing the other side. This
automatically cuts off the proper amount of film and ensures that
the splice will occur at the frame line so that it should not show,

scrapers, but these are not usually much good and often wear a
hole in the film.
The piece to be is joined placed in the other side the same way
