Adjusting movable and fixed knife
① As in Figure 55, adjust the position of the fixed
knife ③ so that the fixed knife right side edge ②
matches the movable knife inner side edge ①.
② The initial assembling position of the movable
knife ④ is where the movable knife-edge
protrudes about 3 mm from the edge of the fixed
blade. Make sure to check the “final fixing of the
movable knife initial position”on page 29.
③ The surface adhesion conditions ⑤ of fixed blade
edge and movable knife upper side have huge
impact on its trimming capacity. Please note the
various cases of movable/fixed knife surface
adhesion conditions on the picture.
(Correcting the adhesive conditions of movable
and fixed knives)
※ As in Figure 55, operate manual trimming
movement with color ink on the movable knife-
edge. By checking the ink trace remaining on the
movable knife, the surface adhesion condition of
the movable/fixed knives can be tested.
※ If the surface adhesion is not very good (same method is used to adjust the tension of movable/fixed knives),
please use the following methods: adjusting the amount and position of the washer ⑦ in the lower side of the
movable knife base ⑥, horizontally adjusting the assembling position of movable knife shaft collar ⑧, and
correcting the shape of fixed blade ⑨ setting position.
