Garments Industry Sewing Machines | Some Essential Sewing Machines | Image & Short Introduction.

A device which is used to stitch fabric and other material with thread is called sewing machine. Most of the garments what we wear are sewn by sewing machines.

Sewing Machine is used for applying stitch in the apparel. Various types of stitching are done by the sewing machine. Depending on the stitch types, Sewing machines are classified. On the other hand sewing machines are classified according to their structure.

Types of Sewing Machines:

Each machine makes a basic running stitch the same way, with two sources of threads. The top needle takes the thread down into the fabric. It is caught and looped via the bobbin apparatus and then pulled back up. The "feed dog" (a rough edged surface underneath the fabric) moves it along and the next stitch begins. Everything else is different.

Mechanical Sewing Machines :

A mechanical sewing machine is controlled by a rotary wheel. Any adjustment like the tension or the length or width of the stitch is made by moving a dial. These machines are very basic and tend to be less expensive than the other sewing machines.

Electronic Sewing Machines :

An electronic machine differs in that there are some functions that can be accomplished by pushing a button. A machine can have a number of motors for various duties and they are run via electricity.

Computerized Sewing Machines  :

As sewing machines became more complex, more of these motors were added. A computer then coordinates all these functions. Think about a repetitive sequence of stitches being programmed, so you no longer have to replicate these movements over and over again. Nice!

15. Zigzag flatbed sewing machine.

Lock Stitch Machine/ Plain/ Regular Sewing Machine:

Lock Stitch is the widely used for stitching fabric. According to the British standard 3870 and ISO4915:1991, lock stitch is classified as class 300.

Plain Machine used for lock stitch, Plain sewing Machine also called lock stitch machine. To Operate this machine one should have practical knowledge about the plain sewing machine.

Feature of Lock Stitch Sewing Machine: Plain Sewing Machine is used for lock stitch formation:

1. Lock stitch is formed by a single needle of a plain sewing machine.

2. The speed of a lock stitch sewing machine is up to 6000 RPM.

3. During stitch formation, the needle thread is interlaced with the bobbin thread by means of a hook.

4. Lock stitch machine can be distinguished by the winding device provided for bobbin thread.

5. The programmable plain sewing machine issued for sewing repetitive operation.

This kind of machines is used for all light, medium & heavy types of garments. Mainly, Collar and Cuff making, POcket Hemming and pocket Attach, Yoke Attach, Shoulder Attach, Sleeve Placket Make, Sleeve Attach, Bottom Hem, Main Label Attach, Top Stitches, Back Moon Join, Placket Join, Various Types of Tack, Zipper Join, Side Slid Make.

 

Lean Tools | 5S | 3rd S Seiso or Shine | Definition and Technique For Implementation.

After completion Seiri and Seiton (that are the 1^st two steps of Lean tools 5S), Now the next step is to implement the third Seiso or Shine.

Seiso is the third stage of 5S (Lean’s Most effective tools) method. Seiso (to make everything shiny clean) is a term that suggests you a highly productive work environment should be clean. Seiso is a Japanese word which means shiny, sweeping or cleaning or systematic cleaning, when using 5S refers relates to cleaning workplace and all equipment and keeps it clean, neat and systematized.  Seiso means remove dust and dirt from a workplace. This 5S (Seiso) is being an operative Lean Manufacturing apparatus which helps with not just your housekeeping, but with enhancing your efficiencies, improving  safety, and ensuring standardized ways of working. 5s benefits are based around the fact that it will help to remove the S7even wastes of Lean engineering from the manners. It has also an advantage to inspecting the apparatuses during the cleaning period, whereby leakage problems, breakdowns, failures, or any type of leakage are identified.

Seiso has 2 most important goals. Those are:

1. To set the new Level for cleanliness.

2. To learn how to keep up that level of cleanliness.

Cleaning is thoroughly related to the proper functioning of the apparatus and the ability to produce quality goods.

Implementation:

For Implementing Seiso, it requires,

1. At 1^st we need to identify the source of dirt and contagion to take root shares for throwing away. Otherwise it would be impossible to keep clean and in good working area.

2. Add cleaning as a part of daily work. A regular cleaning process can be used as a visual inspection of apparatus or the workshop capability. Just as you might notice corrosion or a scrape when washing your car – and not notice it if you just get in and drive – so the workers will have opportunities to catch problems in their early stages. As an example: we had to clean a small puddle of hydraulic fluid – what does this mean about the state of the apparatus?

Even this one-time activity links in with the previous steps of Seiri and Seiton. While acting the one-time "shiny clean" activity, the work teams should ask themselves questions and note the answers:

1.      Does dirt cause problems in operating the apparatus?

2.      Is gravel causing the machinery to wear rashly?

3.      Is the work station clean enough for safety and comfort?

4.      What does the "grime" tell us about the apparatus (like the leaking hydraulic fluid example)?

5.      Is the "mud" – especially powder, gas or liquid – harmful or toxic?

6.      What apparatuses, chemicals or procedures are appropriate?

7.      Could uncaring scrubbing actually damage the apparatus?

8.      Could we implement routine maintenance – like checking the engine oil when washing your car – be executed while cleaning?

9.      Was "clay" hiding any problems, such as decomposing apparatus or uneven floors?

This Seiso steps should be functional before a factory setting and before physical cleanliness. For example guess an office partition. Is dirt adding on a picket of papers? Why are the papers sitting there, relatively than being filed appropriately? Are the computer’s air outlets congested? Are outmoded booklets stored on the computer relatively than on a network backup?

We know that the Seiso step is one time assignment. So it must be documented.

The benefits from The Third 5s-Seiso:

1.      Setting the standard for future cleanliness.

2.      Less lost time for maintenances, since apparatus will be inspected concisely but frequently, and because there will be less grime clogging the apparatus.

3.      Reduce potential risk of accidents.

4.      Improving the physical and mental welfare worker.

5.      The useful life of the apparatus is increased to inhibit any decline from pollution and dirt.

6.      The cleaning leads to a significant increase, in overall apparatus are in top form cleaning.

7.      Wastage of materials and energy due to the abolition of leaks and leaks are reduced.

8.      The quality of Productions is upgraded and losses are avoided by dirt and contagion of the product and packaging.

Main benefits of a Seiso stage come with what is learned:

1.      Actually acting the work validates what was planned – or extends the planning with reality.

2.      Lists of.

3.      Tasks.

4.      Tools, apparatus, detergents or cleansers required for each task;

5.      Series of tasks – wash the machinery before swabbing the floor.

6.      Actual times required by the various chores.

7.      Maintenances required, as noted during the inspections.

8.      Ideas for development – when you do the cleaning yourself you will acquire ideas on how to make the work easier in the future

9.      Employee buy-in: they did the work and therefore they know it can be done and how long it took to do it the first time.
