The Mechanism Of An Automatic Pirn Change Weaving Loom
As the name suggests, automatic pirn change weaving looms are those looms that re designed to automatically change the prins without any required manual tasks. These weaving looms are used to weave various types of fabrics in different garment mills, and are available in different specifications to suit various application requirements. They offer smooth operation, long functional life, and minimum maintenance, all in a very compact design. Furthermore, they have many other distinctive features, such as –
How Are Pirns Wound?
Pirns are rods onto which weft thread is wound for use in weaving. While they sound similar to bobbins, but they are different in that they are fixed in place and the thread is delivered off the end, rather than from the center. They are not wound evenly from end to end in order to ensure snag-free thread delivery. Pirns are generally made of plastic or wood, and are slightly tapered for most of the length, tapering at the end. Pirns are generally used with power looms that have automatic changing mechanisms, which remove the used pirn from the shuttle and replace it with a fresh one, thus allowing uninterrupted weaving.
What Are The Different Types Of Spiral Wound Gaskets Used?
Spiral wound gaskets are made by spirally winding a metallic material and filler material over an inner ring made of special steel. Generally, the metallic material is wound outwards in a circular spiral, and the filler material is wound in the same manner starting from the opposite side; thus resulting in alternating layers of filler and metal. The metal gives structural support, while the filler material acts as a sealing element. Trim Engineering Services are one of the leading spiral wound gasket manufacturers in India, who not only manufacture spiral wound, but also metallic, and non-metallic gaskets with the best quality materials and processes.
What Is The Importance Of Gaskets In The Power Generation Industry?
None of us can imagine life without electricity today, when we are so addicted to and dependent upon electrical appliances like televisions, smartphones, air conditioners, refrigerators, microwave ovens, and so much more. And, to bring in all the electricity we use up every day without giving it even a single thought, the power generation stations are the main source. And, the power generation industry also produces energy in a variety of ways using various options like natural gas, coal, fossil fuels, wind, biomass, and solar and hydroelectric methods.
Why are gaskets important in the power generation industry?
Power plants require huge amounts of resources and large land spaces to convert electric power on huge scales. Such power generation and conversion requires a high number of power sources like gas-fired, oil-fired, coal-fired, nuclear, and hydro-electric. Whatever the power source, the power generation industry requires highly flexible materials that can withstand all kinds of temperatures, pressures, and conditions, like insulation, taping, and gasketing. To help withstanding these immense temperatures, pressures, and other conditions, durable gaskets and sealing solutions have been adopted. These gaskets are designed to handle a range of operating pressures and conditions so that they can effectively and evenly distribute power across long distances. Expert spiral wound gasket manufacturers in India undertake the responsibility of fulfilling this requirement of working towards optimal efficiency while simultaneously minimizing costs.
What makes spiral wound gaskets an ideal choice?
Spiral wound gaskets are created with a combination of a variety of smart materials like a preformed metal strip with a compressible soft filler material – a combination that results in a highly responsive and extremely tight seal. The shape of the metal strip behaves like a spring under pressure, making the seal highly resilient, in spite of any alternating conditions. These gaskets offer a versatile energy-saving option for a variety of applications like generators, boiler feed pumps, low-pressure turbines, crossover pipe flanges, lube oil systems, and condenser systems.

Which Bobbin Styles Are Available For Industrial Sewing Machines?
Just like sewing machines are of various types; so are the bobbins inserted in them. Bobbins form one of the most important parts of a sewing machine; and a wrong bobbin can cause damage not only to the stitch and fabric, but also serious damage to the machine. This is why it is important that you know about the various styles of bobbins so that you know which bobbin you require for your particular application. Let us take a look at the various bobbin styles that various bobbin manufacturers in India produce.
Style 41 bobbins
These are the most common pre-wound bobbins that are used in Class 7 sewing machines. These bobbins are used to sew synthetic web slings and tie downs.
Style 58 bobbins
These pre-wound bobbins are used to sew canvas, covers, and tarps.
Style A bobbins
These bobbins are used in industrial and commercial sewing machines to sew garments, as well as in home embroidery sewing machines. Because they have a comparatively wider size, they allow more thread to be woven over them, making them one of the most preferred bobbins.
Style M bobbins
These bobbins are used in industrial and mid-large sized commercial sewing machines to sew canvas, heavy fabric, upholstery, and leather.
Style U bobbins
Slightly smaller in diameter than Style 58 bobbins, the Style U bobbins are used for sewing nets, tie downs, and tarps in both industrial and heavy-duty commercial sewing machines.
Style G bobbins
These bobbins are used in small to medium sized industrial sewing machines.
Style L bobbins
While these bobbins are majorly used (40%) in home sewing machines, they are also used in many long-arm and commercial embroidery machines.
Which bobbin does your machine require?
With all these styles of bobbins and many more varieties, it is important that you know which bobbin style your machines require. The bobbin you use should be able to serve the purpose your machine is to fulfill. So, how do you know which bobbin your machine requires? Here are a few ways to find out.
Check the user manual – The best and easiest way to find out is by looking at the user manual you got with your machine. The manual will definitely have the size and style of bobbin mentioned.
Consult your machine’s manufacturer – If you have lost your manual or are unable to find about the bobbin style written in it, you can contact the machine’s manufacturer who will be able to confirm for you the size and style of bobbin your machine requires for effective operation.
Check your last bobbin – If you have been using your machine for a long time and now are in need of new bobbins, check for the box or packaging of your previous bobbins. The style and size will undoubtedly be written there.
The last option – If none of the above is possible for you, the last option you have is to compare your used bobbin with various new bobbins. Measure the various dimensions of your current bobbin and look for a new bobbin to match those exact measurements.
Trim Engineering Services is one of the most renowned and reliable bobbin manufacturers in India who produces various kinds of bobbins for a wide range of industries like fishnet twine, tire cord, spinning, jute, silk, rope yarn, and many others.

Are You Sure About The Embroidery Bobbin Thread You Are Using?
Bobbin thread is a lightweight thread, specially designed to be used in machine embroidery. It is fine enough to keep compactly embroidered designs from being too rigid; thus avoiding puckering of fabrics. But, although fine and light in weight, it is strong enough to withstand the stress of high-speed stitching required in the functioning of embroidery machines. This proves that bobbin thread is much better than a regular thread. Also, the fineness of bobbin thread allows more thread to be wound on the bobbin than a regular thread.
Which weight of bobbin thread should you use?
Bobbin threads come in a 40-60 weight thread. The 40 weight thread is slightly heavier than the 60 weight thread, but it is generally the 60 weight thread that is used for filling denser designs with no breaks. However, whichever thread it may be – 40 or 60 weights – both are made of polyester, making the thread very strong, resulting in less thread breakage.
Which colour bobbin thread should you use?
Generally, you would say that one must use the same coloured bobbin thread as the embroidery thread colour. That’s a good idea, but it sometimes has its limitations! For example, when you are sewing an embroidery design that involves 10 different colours, would you want to keep changing 10 different bobbins? That would be a time and effort demanding task, which won't be wise. Yes, when the design involves satin stitch, you would have no option but to use the same bobbin thread colour as the embroidery thread, in order to give a neat and finished look to your design. But otherwise, it is preferable to use a single common bobbin thread colour for the entire design to avoid making it difficult and time-consuming. Satin stitches require the same coloured bobbin thread as that of the embroidery, meaning that bobbin threads are available in multiple colours. But, the most commonly used threads are black and white, used as common backgrounds for all designs – black for dark shades and white for light shades.
Should you buy pre-wound bobbins?
There are options of buying pre-wound bobbins available in the market by various manufacturers that can work well with your machine. Buying pre-wounded bobbin threads can help you pave a faster path towards completing your embroidery project, rather than buying spools of bobbin thread and winding them on your own empty bobbins. These pre-wound bobbins are available in various colours and quantities for you to choose from. So, you can opt for this alternative to save a lot on your time. However, pre-wound bobbins are only for single usage. Once you use up the bobbin thread, you cannot use the paper or plastic spool for rewinding a new thread. Also, make sure that the pre-wound bobbins that you are purchasing comply with the type of your machine. Check what your machine supports and buy your bobbins accordingly to avoid any kinds of hassles and possible breakdown of the machine, thus delaying your project considerably. This is because not all machines can use pre-wound bobbins, and not all machines can take up any kind of pre-wound bobbin. So, if you decide to be on the safer side and buy spools of thread to be wound by you, you can get in touch with Trim Engineering Services. They are the most reliable bobbin manufacturers in India, where you can get a wide variety of bobbins for various uses like nylon flange bobbins, wooden bobbins, plastic bobbins, aluminum bobbins, and many more.
