III -d-2 When
the scanning
finger of a
touch lever finds
a punched hole
and
comes
through it, that touch
lever will be at
higher position and
does not push
the upper part of
Main Drum Piece
leaving the lower
part in inner
position
(inactive) and therefore
does not activate
(push) Sub Drum
Piece.
Accordingly the lower part of
Sub Drum Piece
remaining
lower position will
push the butt of a
corresponding needle
forward so that
the needle will proceed
along the front edge of
Separation Cam to be
pushed more forward
to selected course.
