Class 100 Stitches

Class 100 stitches are single thread chain stitches using one needle thread and one blind looper. Feature

A piece of thread is interlaced like a chain under the cloth and the stitches are formed as knitted. The constructive feature is that the stitches are untied one after another when the interlacement at the end of sewing comes off.

ApplicationBasting (ML-111), button sewing (AMB-189N), (MB-377), chain stitch buttonholing (MBH-180S), blind stitch, And closing of bag opening.

Example of Stitch formation

Stitch formation:

A: Needle thread slacks at the position where needle slightly goes up from its lowest position, and looper catches the needle thread which has become like a loop.Also, the needle enters the circle of needle thread which is widened by the looper.

Looper

Needle

B: Needle comes off the cloth and the cloth is fed. Looper rotates and removes the thread which the looper caught before while pulling in the needle thread. Needle bar continues going up and needle thread take-up lever lifts the thread.

C: Looper continues rotating and pulls in the thread in the center of the looper and thread take-up lever tightens the thread which the looper removed before.

D: Cloth feed is finished and a stitch is formed. Needle penetrates the cloth to continue to next stitch, A.

We get class 100 stitches from SNCS, blind stitch machine etc.

Class 103 One Thread Blind stitch for Hemming

Class 104 One Thread Blind stitch for Hemming

Class 200 Stitches

Single thread hand sewed stitches using one needle thread. Feature

Same stitch as that of hand stitch is formed by a piece of thread. Thread is drawn in every stitch or every other stitch and the length of stitching is limited. Since friction is given at the same position of the sewing thread many times, the thread is untwined during sewing resulting in thread breakage unless the thread is a high-durable one. Even when the sewing is made, the stitch looks broken. Therefore, the thread that can be used is limited.

ApplicationDecorative stitch of suits or like, kimono (Japanese national dress), Button sewing of coats, suits, etc.

Class 200 Hand Stitch

A: Needle is fixed to upper needle bar, and left-hand and right-hand loopers draw and retain the thread. Cloth is fed and the needle comes down.

B: Needle penetrates the cloth and is delivered to the lower needle bar. The right-hand looper returns to its home place.

C: Lower looper catches the thread loop at the position where the lower needle bar slightly goes up from its lowest position.

D: Lower looper draws out thread which enters under the cloth one stitch before from the above left-hand looper. Simultaneously the cloth is fed.

Page 4 of 57

E: Needle goes up and penetrates the cloth. Lower looper further pulls in the thread downward.

F: Needle penetrates the cloth, and is delivered to the upper needle bar and goes up. Thread is wiped out by the lower looper. Next, the above left-hand and right-hand loopers catch the thread to continue to A.

Diagram Stitch Class No. of Thread Typical Uses

Class 202 One Thread Basting, Tacking or Repairs

Class 205 One Thread Pick Stitch - Topstitching

Class 300 Stitches

Two or more thread lock stitches using needle thread(s) and one bobbin hook thread.

Feature

Page 5 of 57

Two threads of upper thread (needle thread) and lower thread (bobbin thread) are used. Every stitch upper thread and lower thread interlaces each other and the stitches on right and wrong sides are the same. This stitch is widely used since it is not easily frayed and securely joins plural pieces of cloth. It is necessary to replace the bobbin thread since stitch formation is obtained by rotation of the needle thread around the bobbin case.

ApplicationGeneral sewing (DDL-5550N, DDL-5700-7, DLU-5490N-7, DLN-5410N-7), Shirring (DLU-5494N-7),2-needle lockstitch (LH-3128-7), Zigzag stitch (LZ-2288N-7), Plain stitch, Decorative stitch, Bartacking (LK-1900), Lockstitch buttonholing (LBH-790RS-1), Button sewing (LK-1903/BR25), Pockect sewing (APW-196) and Pattern sewing (AMS-210D)

Example of stitch formationJIS mark 301 ... 1-needle lockstitch JIS mark 304 ... 1-needle lockstitch zigzag stitch

A: Upper thread slacks at the position where the needle slightly goes up from its lowest position, and blade point of outer hook catches the loop-shaped upper thread and pulls in the upper thread.

B: Upper thread which is pulled in by the blade point of outer hook is separated at the inner hook thread separating portion so that the upper thread on the needle side is separated to the rear side of inner hook and the upper thread on cloth side is separated to the right side of inner hook.

C: Outer hook rotates, while pulling in upper thread, around the periphery of bobbin case containing lower thread set in inner hook. Thread take-up lever supplies upper thread which is necessary to rotate around inner hook. (Suppose that inner hook is a human being, and it looks like doing rope-skipping.)

D: Immediately after upper thread hasrotated around inner hook, threadtake-up lever lifts upper thread and theupper thread is interlaced with the lower

E: Stitch is formed when the upper thread lifts the lower thread and cloth is fed at the end. Next, needle comes down and penetrates cloth to continue to A: .

A: Blade point of semi-rotary hook catches loop-shaped upper thread.

D: Upper thread rotates around the periphery of bobbin case by rotation of the hook.

C: After 1/2 rotation of the hook, upper thread is lifted by thread take-up lever and is interlaced with lower thread.

Feature

Page 9 of 57

Upper thread (needle thread) and lower thread (looper thread) are interlaced with each other like a chain under cloth, and the stitches look like knitted. The stitches look the same as those of lockstitch when observing from the surface of cloth. Sewing can be performed continuously for a long time since lower thread as well as upper thread can be supplied continuously. Stitches are full of elasticity, and widely used for the elastic cloth and places to which shock is applied. Defect, when compared with the lockstitch, is that the stitch is easily frayed.

ApplicationGeneral sewing (MH-481-5) Rubber tape attaching, Lace attaching to underwear, swim-suit, etc. Eyelet buttonholing (MEB-2688), Side seam (MS-1190), Belt loop making (MFB-2600)

Example of stitch formationJIS mark 401 ... 1-needle double chain stich JIS mark 406 ... 2-needle double chain stitch

Stitch formationA: Needle thread comes off looper and is tightened. Then, looper scoops needle thread at the position where needle slightly goes up from its lowest position.

B: Needle continues to go up and looper thread comes off needle. Looper advances in the state that it has scooped needle thread.

Page 10 of 57

C: Cloth is fed when needle is in the highest dead point and looper is in the most advanced state, and the final tightening of needle thread is performed.

D: Needle comes down and the needle tip scoops looper thread. Looper performs elliptic motion. Then, stitch formation is continued to

Class 500 Stitches

Multi-thread over Edge chain stitches using needle threads and looper threads. Feature

In many cases, three threads of upper thread (needle thread) and lower threads (upper looper thread and lower looper thread) are interlaced with one another so as to hem material end, and the stitches look like knitted.This stitch belongs to the classification of chain stitch. The stitch itself can expand following the expansion of cloth. Accordingly, this stitch is mostly used for the cloth which is largely expanded (knit or the like).

ApplicationCloth which is largely expanded, blind over-edging, prevention of fray at material end (ASN-397/serging machine) Over lock sewing machine (MO-3904), 2-needle over lock machine (MO-3914), Cylinder-bed over lock sewing machine (MOC-3914)

Page 11 of 57

Extra: Compound stitching Feature

This stitch is favorable to the productivity since double chain stitching and over-edge chain stitching are simultaneously performed (safety stitch). The machine is called "Interlock machine". (MO-3916)

ApplicationGeneral run stitching, side joining of shirts, slacks, etc.
