IX. WORK WITH AIR TUCKING
Throat Plate
For air tucking use the zig zag throat plate. The bight
regulating lever "A” is set for straight sewing and
the needle position lever "B" is set for central posi
tion (see Fig. 26).
To Attach the Two-Needle Clamp
For plain stitching and for zig zag work the Class 216
g
Machine
is
provided
with
a
needle
clamp as shown in Fig. 66 and a
SINGER
flat
shank
needle
Class
15X1.
For
air
tucking
loosen
the
screw (S, Fig. 66) carefully, detach
the needle clamp and fasten in its
place the two-needle clamp (Fig. 67).
The clamp is attached by sliding it
up the needle bar until the position
pin 1 (Fig. 67) of the needle bar
engages the groove 2 (Fig. 67) in the
upper
edge
of
the
needle
clamp
whereupon the set screw (B, Fig. 67)
is tightened. This is necessary before
inserting the needles, since the end
of the needle bar serves as a stop
One-Needle Clamp for the correct height of the needles.
Needle Types
To differentiate from needles used in the single needle
clamp, the needles used for air tucking are SINGER
Round Shank needles of Class 16X1. This type of
needle is chosen because it is possible to obtain a
smaller
distance
between
the
needles
than
with
flat
shank needles. Needle size No. 9 is recommended for
fine material and No. 11 or No. 13 for all other
materials.
