INDUSTRIAL SEWING MACHINES
INDUSTRIAL SEWING MACHINES
The democratization of fashion began with the invention of the sewing machine,
which turned a handicraft into an industry. The sewing machine made the mass production of clothing
possible. Fundamentally sewing machines are categorized under four main titles in this chapter.

Class 200 - Rand Stitch
 Generally formed by hand, the hand stitch is made with a needle that is passed from one side of the
material to the other as a single line of thread.
 The most important machine to duplicate this stitch is a pick stitching machine, which is used as a
decorative detail on the other edges of jackets.
Class 300 – Lockstitch
 The most common stitch type, the lockstitch has two or more groups of threads that interlace to
form the stitch.
 One group is called the needle threads and the other the bobbin threads. These stitches do not
unravel easily and always require a bobbin.
 Very versatile, they are used for seaming, hemming, and setting zippers and pockets.
Class 400 - Multi Thread Chain stitch
 Sometimes called a double-locked stitch, the multithread chain stitch has two or more groups of
threads that interlace and interloop with each other.
 One group is called the needle threads and the other the looper threads. This stitch is actually
stronger than the lockstitch; however, if the threads are not properly secured on the finishing end, it
will unravel.
 It is used for seaming and in combination with the over edge stitch on over lock machines.
Class 500 - Over edge Stitch
 The over edge stitch is formed with one or more groups of threads that interloop to form a
thread sheath around the fabric edge.
 The most common stitches have one or two needle threads and one or two looper threads.
Overedge stitches are v elastic and do not in unravel easily.
 They are for neatening edges trimming woven and low stretch knitted fabrics and decorative
edgings.
Class 600 – Cover stitch
 The most complex stitch class, the cover stitch is generally formed with three or more
groups of threads that cover the raw edges of both surfaces.
 Very elastic, It is used to create low -bulk and decorative seams on underwear and knitted casual
garments. Threads should be strong with a soft hand.

SEWING MACHINE NEEDLES
In the apparel industry, there are literally thousands of different machines, each requiring
a different needle type. On most new machines, the needle type for that particular machine is
identified on the machine head. However, each needle manufacturer identified its needles in a
different way; the needles for the same type of system may have several different names or numbers,
depending on the manufacturer.
Needle Size
The needle size can be as small as 60 (0-6mm) or as large as 250 (2.5 mm). The metric size
describes the diameter of the needle blade in hundredths of a millimeter. The needle size is
determined by the thread size.
Shank :
The shank is usually round, but it can have one or two flat sizes.
Designed to support and stabilize the needle blade, the diameter of the
shank is usually larger than the diameter of the blade
.
Scarf:
A small indentation above the eye that permits the hook or looper to
pick up the thread loop. On some needles, the scarf is elongated and/or
deeper to ensure that the needle thread loop will be large enough to
prevent skip stitching.
Eye:
An opening in the needle blade at the lower end of the long groove
that carries the thread into the material to the hook or looper to make a
stitch. The size of the eye is proportional to the diameter of the blade.
Point:
The tapered end. It is often considered the most critical aspect of the
needle. Generally round points and ballpoints’ are for woven and knit
fabrics because they can penetrate the fabric by spreading the fibers or
deflecting the yarns without damaging them.
Needle groove (long groove):
A g channel on the black it is located on the side on which the needle
dread enters the eye a provides a protective guide for the thread when
the needle is rising and the needle- thread loop is enlarging.
Front view
Back view
Short groove:
Located on the side opposite the long groove, it is a guide for the needle thread and protects it from abrading
when passing through the material.
Needle shape
If the needle is too fine, it will abrade the thread bend, break, affect the loop formation, and
cause skipped stitches. If it is too course, it will damage the fabric, produce an unattractive seam, cause the
seam to pucker, affect the loop formation, and cause skipped stitches.

 Double needle lock stitch machine
Single needle lock stitch
Introduction
This machine has a needle thread as well as a bobbin thread for the loop formation purposes. Loop
formation of this machine occurs according to the interloping terminology.
Single needle lock stitch machine specification
Methodology behind the loop formation
 The formation of a stitch begins when the needle
penetrates the fabric and descends to its lowest point.
 The bobbin hook then slides by the needle’s scarf,
catching the upper thread, and carries it around the
bobbin thread.
 The thread is then pulled up into the fabric, completing
the stitch.
Double needle lock stitch machine
Introduction
This machine has two needle threads and two bobbin threads to form lock stitch. Double needle lock
stitch machines stitch formation is same as single needle lock stitch machine but forms two lock stitches
which are parallel to each others.
Overlock stitch formation machine
 2 Thread overlock
 3 Thread overlock
 4 Thread over lock
 5 Thread over lock
 6 Thread overlock
Introduction
Overlook machine is a special purpose machine used for finishing edges and sometimes for
seaming. It falls under the class 500. Stitch types in this class are formed with one or more groups of
threads and have general characteristics that loops from at least one group of threads pass around the
edge of the material.
Methodology behind the stitch formation
 When the needle enters the fabric a loop is formed in the
thread at the back of the needle.
 As the needle continues its downward motion into the fabric, the
lower looper begins itsmovementfromlefttoright.Thetipofthelower
looperpasses behind the needle and throughtheloopofthreadthathas
formedbehindtheneedle.
 The lower looper continues along its path moving toward the right of the
serge.Asitmoves,thelowerthreadiscarriedthroughtheneedlethread.
 While the lower looper is moving from left to right, the upper
looper advances from right to left. The tip of the upper looper
passes behind the lower looper and picks up the lower looper
thread and needle thread.
 The lower looper now begins its move back into the far left
position. As the upper looper continues to the left, it holds the
lower looper thread and needle thread in place.
 The needle again begins its downward path passing behind the
upper looper and securing the upper looper thread. This
completes the overlock stitch formation and begins the stitch cycle
alloveragain.

Introduction
The machine is intended for the elastic lace attaching of shorts, lingerie and foundations. The
right hand fabric trimmer cuts the multi-layered section of joined seams without fail to achieve uniformly
and beautifully finished seams, with the seams and material-edge aligned. Although this machine can be
used for the hemming process of the sleeves and bottoms of T-shirts and for the covering process for
sportswear and knitwear. It is not a specific-purpose model, but a basic one which can be used for a
broader range of processes independently.

Introduction
The machine is designed specifically for the attaching of waistbands to jeans,
casual pants, etc. The machine supports two different waistband styles; "pre-cut style" and "continuous
band style. Accurate stitching performance and durable finished seams are particularly necessary in the
chain stitching process.
2-needle, for light- to medium weight
3-needle, for heavy-weight
Thanks to the thread guide located between the needle bars thread take-up and the
intermediate tension release lever, the timing to tense the needle thread can be decreased. As a result,
the machine is capable of beautiful stitches with a soft appearance even when heavy-weight material
is used.
