th;ead

on

the

hook's

second

revolution,

that

is

to

say,

if

the

hoolt

up

the

needle

thread

after

just

discharging

it,

or

if

the

hook

completely

fails

to

discharge

the

needle

thread,

thread

breakage

will

result.

These

"second

revolu-

tion"

breaks

may

be

due

to

several

things,

among

which

are;

the

hook

is

too

fast,

insufficient

tension

on

the

needle

thread,

insufficient

tension

on

the

thread

controller

spring,

or

a

combination

of

these.

or

blunt

needles

are

frequently

the

cause

of

skipped

stitches.

use

a

sharp

needfe

and

see

that

it

bea.rs

on

the

needle

guide

while

entering

the

goods.

Of

course,

when

the

needle

is

com-

pletely

in

the

goods,

there

should

be

clearance

between

the

needle

and

the

needle

guide.

Occasionally

the

plunger

may

be

the

cause

of

skipped

stitches

due

to

its

being

set

too

low.

Adjust

the

plunger

higher.
