XI -b Adjusting the clearance between
Touch Lever and Main Drum Piece.
XI -b-1 In case of the
imperfect adjustment of the clearance.
When Punched Card is
inserted in the Slot of Pattern
Panel, Touch
Lever reads the
patterns by pushing their
scanning fingers into the
Punched Card Holes. The
Touch Levers remaining
at the lower position
push Main Drum
Pieces. But in case
there is much clearance
between
Touch Leveres
and Main Drum Pieces, Touch
Levers can not transmit
the
pattern to Main Drum.
Picture below shows
the fabric with
broken patterns caused
by incorrect
clearance between Touch
Levers and Main Drum
Pieces.
