DNLS or Double Needle Lock Stitch Machine

Lock Stitch Machine is the most common and high demanding machine for men & women’s clothing varieties. Lock Stitch Machine uses two threads, an upper thread which comes from the sewing needle and the lower thread which is coming out from the bobbin. The two threads upper & lower threads lock together in the hole in the fabric which they pass through. 

To make a stitch, the machine lowers the threaded needle through the cloth into the bobbin area, where a rotating hook catches the upper thread at the point just after it goes through the needle. The hook mechanism carries the upper thread entirely around the bobbin case, so that it has made one wrap of the bobbin thread. The take-up arm, then pulls the excess upper thread (from the bobbin area) back to the top, forming the lock stitch. Then feed the dogs pull the material along one stitch length, and the cycle repeats.

There are two types of lock stitch machine according to the number of sewing needles and bobbins, they are:

1. SNLS or Single Needle Lock Stitch Machine.

2. DNLS or Double Needle Lock Stitch Machine.

A double Needle Lock Stitch Machine works on the same theory as the SNLS machine while using two needles and two bobbins thus resulting in two parallel rows of lock stitch.

When the stitch forms, correctly equal amounts of bobbin and needle thread are used. Upper and lower threads interlock in the center of the fabric.

The double needle lock stitch is the tightest and most secure stitch.

Box Pockets on safari jackets, light jeans and pyjamas, top stitch front collar edges of safari jackets, sew pockets on coats, sew skirt box pleats, top stitch the collars of ladies wear, top stitch the cuffs of ladies wear, suitable for sewing shirts, uniforms, jeans and women underwear, inseam of the trouser,  etc. are sewed by double needle lock stitch machine.

Advantages:

1. Lock Stitch Machines are versatile and can be used for a variety of operations.

2. Compare to all other stitch types, this class uses the least amount of thread and produces the flattest stitch.

3. It is reversible.

4. The double needle lock stitch is the tightest and most secure stitch.

5. It is the only stitch formation that can be back stitched if the ends need to be secured.

6. It is non-revealing.

7. Good hands.

8. Lies flat on the fabrics.

Lean Tools | 5S | 2nd S Seiton or Set In Order | Definition and Technique For Implementation.

In My Previous page I was trying to discuss about 1^st S (Seri or Sort) from the Japanese 5S System, which is the Lean System’s 1^st Fundamental Principle. In this I want to discuss about the 2^nd S, Seiton or Set In Order. It is also called Straightening or Organizing or Orderliness. That is, setting everything in proper order for easy reclamation.

It involves setting in order what is sorted in Seiri, straighten and standardization of it. Where Seiri subsumed getting rid of the things that you do not need or necessarily, Seiton ensues closely on by assuring what you remove is orderly and available where and when you need it. 

Seiton means orderly placing the objects away after you have used them. Placing objects away requires following 3 rules:

1.       Fix where objects belong,

2.       Decide how objects should be put away,

3.       Follow the put-away rules to leave objects where they can be quickly and properly found next time they are needed.

To fix the put-away rules, do an analysis of how the objects are used. Pay particular attention to when and how they are picked up and used. This is the initial conductor of how and where they are put away. If something used 50 times a day, then this multiplies the time wasted in finding, the finding the item and taking it to where it is to be used. Seiton’s determining where and when objects are needed, placing them in a way that promotes efficient work flow. A worker should not have to hunt for necessary tools, or walk to another area to access often-used items.  

Now let’s find out how it is working?

The object of Seiton is that everything should be stored competently. Practically, this means, store the objects where they will be used. The more frequently it is used , the closer It should be kept. And reduce clutter by storing rarely used items further away. 

Visual Communication of Seiton:

Where confusion exists about the objects, then it should be identified in some way. For example, when selecting something is uniquely marked, for example, with standardized numbers or colors, then error and following wastes can be eliminated. The visual identification and communication are also critical to Seiton implementation. Objects that are used frequently, must be  labeled to document dates of use to determine priority of location. Items are labeled so that there no mistakes will happen. Labelling and naming should be similarly standardized. Each and every label must be located where this object  belongs to.  Seiton should be clearly communicated to the correct location.

Seiton Keep the most frequently-used objects right in the sequences:

1. Handy

2. Visible

3. Easy to reach

4. Easy to put back when not needed.

Daily or Monthly objects might be kept somewhere in the belonging marking area. You may use store room, but this storage area should still be visible from the area of the work station. Rarely-used objects or spare parts could be stored away from the work station.

Now we need to build a culture. It is one thing to set up storage areas. It is another to have people use them properly. Management must begin implementing a culture where workers, as a matter of course and a matter of pride:

1. Store Objects where they belong.

2. Keep the work area tidy.

A misplaced object will be visible at a glance in a well run factory.

When we are Doing the job Seiton or Set in Order, there should be needed to raise some questions.

1.    How often is it used?

2.    Is it easy to reach the items?

3.    How to Store it? And

4.    How to maintain it every day properly?

Usefulness to use Seiton:

1.   Increase productivity by decreasing the time spent retrieving an object.

2.  Cost savings because lost objects do not need to be re-ordered.

3.  Reduced injuries because tools are stored in convenient and ergonomic places-workers make less bending, lifting, twisting & stretching.

4.  Increase productivity because it is clear when objects are indeed unavailable.

5.  Easier For any kind of cleanup.
