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.
