properly

all times.

The Inner

cam

acts on

the

upper

spreader

the

three

stacked

ornament

spreaders,

and

the

outer

cam

acts

the

two

lower

spreaders.

The

outer

Be sure

use

the

and

shift

the

upper

Note

that

this

screw

has

left-

handed thread. Then, remove the

outer

cam (C).

The collar (D) isexposed. Remove three tightening

screws, and

take

out

the

collar.

Then,

cam (E) can

be easily replaced. Before mounting a new cam,

be sure to apply grease In the cam groove. Do not

loosen screws

other

than

those

described above.

Otherwise, upper ornament timing will become

defective.

3. Cam timing

* Set No.8 cam at the inner side, and No.l cam at

side.

Set the both

outer

and intermediate levers (A)

around

the

center of the slots, and connect them

the

feed

eccentrics

which

are

connected

the

ornament

spreaders. After connection,

the

three

spreader start moving. To adjust cam timing,

loosen and set the four screws for tightening the

collars (C) so that the three spreaders stop moving

when the needle ends reach the uppermost spread

ers. After adjustment, securely tighten the four

screws.

Adjustment of upper ornament spreaders

* First, Install the upper ornament spreader so

that

the

bottom surface of the base on which the spreader

is installed is 15mm (distance (G)) from the upper

surface of

the

needle plate. When

the

above distance

(15mm)

is set at both right and left

sides,

tighten

the two hex head

screws

(D), and then tighten the

other two screws (E) after checking the distance.

Next, install

the

lowest spreader (C) of the three so

that it

moves

smoothly without contactingthe

presser

foot when the spreader is slide from right to left

while it is lifted by approx. 0.2mm. The clearance

between the spreader and needles should be 1.0 -

1.2mm. When the spreader is not parallel to the

twelve

needles,

loosen

screws

(D)slightly and correct

the spreader so that it is

parallel

to the

needles,

and

then retighten the

screws

(D). Next,

install

spreader

(B)

the

same

way

spreader

(C)

while

eliminating

the clearance between spreaders (8) and (C). Care

should

used

prevent

the

spreaders

from

coming

too

close to one another, since this causes unsmooth

movement. They must move smoothly. Next, install

spreader (A) in the same way as spreaders

(C)

and

(B).

After

installing

the three

spreaders,

try to

move

them up-to-down. Adjust four

screws

on spreader

(B)

so that the clearances between the spreaders in the

vertical direction is

approx.

0.5mm.
