50. SMOCK STITCH
For this type of work, use light ma-
terials like satin.
Set machine as for sewing with
twin needle.
- Cam group:
no. IV.
- Knob " A
»
about on 1 .
- Lever " B
» :
in left notch.
- Lever " C
» :
on the left.
- Knob " D " : about on 0.5.
- Thread: use embroidery thread
no. 50.
Sew parallel lines of stitches so that
the point of every line is always in
correspondence with the point of
the preceding one (Fig. 70). Even-
tually correct direction of sewing,
guiding fabric by hand.
51. LEVER FOR MICROMETRIC
ADJUSTMENT OF DESIGN
For the normal execution of the
designs (Fig. 72a) set lever
«
E
»
(Fig. 71) with its pointed end on 0.
Slight shiftings of said lever in
respect of position 0 might some-
times be required to obtain drawings
answering better the operator's
purposes.
- To increase the forward stitch
length or decrease the reverse
stitch length,
shift
lever
«
E
»
towards "
+
».
Design will thus
be as shown in Fig. 72b.
- On the contrary, to decrease the
forward stitch length and increa-
se the reverse stitch length, shift
lever " E • toward
u -
».
Design
will thus be as shown in Fig. 72c.
It is advisable that the lever
shifting in both directions should
always be very small due to the
fact that this device is very sensitive.
CHARTS OF AUTOMATIC EMBROIDERY DESIGNS
The following charts illustrate a few examples of designs that can be made
with the earns contained in the accessory box of machine.
Many other decorative stitches can be obtained by changing the positions
of the machine levers, or by combining the cams differently.
When consulting the Charts, always refer to Fig, 1.

When combining the separate
cam groups, make sure they
are inserted on cam-holder
bushing in the correct order.
~17171717sl7
The cam-group for scalloping,
which is now replaced by group
V can be made-up by cams
0 - 0 - 24 and machine controls
#et at will.
The following examples are all
obtained by always turning the
mark lines
«
r » stamped on
each cam face, in the same
direction so that they are one
above the other (see note in
para. 42).
