The

needle bed

guides

the back

of

the needle

d detennlnes the pitch

of

stitches.

2.

Combs

Th

3. Plain needle
The

plain needle is moved back and forth

by

the cam attached to

the

carriage

In

order

to

make needle loops.

4. Belt
When the carriage is moved

to

select

the

needle

by

the card ,

the

belt

begins

to

tum

and drive the needle selecting mechanism and

also synchronizes the

carria~e

and

needle selecting timing.

S. Needle ltkctOI' plate

The

needle selector

plat

e is made

up

of eight pattern plates

of

the

sa

me design which

are

overlapped

with

an

offset

of

one pitch.

It

causes

the

hook

of

the

needle selector plate

to

hook

the

plain

needle shunk when the needle selector plate corresponding

to

an

open hole

in the punched card

Is

moved

to

the right.

Thus,

the

and

the needle shunk is caught

to

the D position by the separation cam.

On

the needle which

in

an open hole, the card

reader does

not

move

up,

and u a result, the needle cannot be

held down (in
