What Defines The Efficiency Of Winding Pirns?

Pirns are rods onto which weft thread is wound for usage in weaving. They are long rods made of wood or plastic, tapering for most of its length, and flaring out more sharply at the base. They are similar to bobbins, only with the difference that pirns are tapered, and that they are not wound evenly from end to end as in the case of bobbins. They are wound completely on one portion of the pirn, and then moving on to another portion. For the best quality pirns, you can get in touch with Trim Engineering Services, the leading pirn manufacturers in India since the past 30 years!

Different Types of Bobbins

Bobbins are those tiny elements that fit into a sewing and embroidery machine that holds the thread to stitch the fabric, or the design onto the fabric. While these bobbins are a very important constituent of a machine, they are almost always forgotten about. Both sewing and embroidery machine bobbins are different, you may know that already. But, do you know that in all, there are more than 60 different bobbin styles available!? While some are quite different, there are others that are so similar, that it is difficult to see any difference at all. We won't be speaking about all 60 of those bobbins, but let us take a look at some of the most commonly used bobbins.

Class 15 (A Style) Bobbin

Class 15 or Style A bobbin is about the size of an American nickel, with a diameter approximately 20.3 mm and width approximately 11.7 mm. It has two flat sides, and is available in both metal and plastic.

Class 15J Bobbin

Another bobbin that is about the size of an American nickel, the Class 15J bobbin has a diameter of approximately 20.4 mm and width approximately 11.3 mm. But, this bobbin is available only in plastic. While it looks similar to a Class 15 bobbin, it has a slight curve to its sides. This curve is barely visible, but it can significantly affect the performance of the bobbin. Thus, Class 15J bobbins cannot replace Class 15 bobbins in a machine.

Class 66 Bobbin

Class 66 bobbin is yet another bobbin that is about the size of an American nickel. It has a diameter of approximately 20.5 mm and a width of approximately 10.9 mm. It is available in both metal and plastic. It has a significant curve on the sides, and appears to be same as the Class 15 bobbin; however, it cannot replace the bobbin in any machine.

L Style Bobbin

Style L bobbin is the size of an American nickel, measuring approximately 20.3 mm in diameter and approximately 8.9 mm in width. It has two flat sides, and is available in plastic, aluminum, and Magna-glide core.

M Style Bobbin

Style M bobbins are about the size of an American quarter, with a diameter of approximately 24.9 mm and width of approximately 10.7 mm. It has two flat sides, and is available in metal and Magna-glide core.

Now that we know about the most common bobbins that are used depending upon the structure and size, let us look at some others that are classified based on the material they are made of. While there is a list of materials that bobbins can be made of, the most common ones include metal, aluminum, and plastic.

Metal bobbins – These are the most common bobbins used, made of treated steel. These are often preferred over aluminum and plastic bobbins.

Plastic bobbins – These bobbins are becoming more popular as they are durable and inexpensive, and they generally perform just as well as metal bobbins.

Aluminum bobbins – These bobbins are light in weight and spin faster than metal and plastic bobbins. They perform better than metal and plastic bobbins, but can easily be scratched and damaged.

One other important thing to note here is that bobbins are often confused with pirn. But, both bobbins and pirns differ a great deal. Pirns are rods that taper at the sides, and are not wound evenly from end to end like bobbins. Thus, while they perform similar in fashion to bobbins, they are actually quite different. But, whatever your requirement, you can get them all at Trim Engineering Services, the leading bobbin and pirn manufacturers in India.

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.

Why choose gaskets from Trim Engineering Services?

You can rely upon the products and services of Trim Engineering Services, one of the most renowned spiral wound gasket manufacturers in India, who can help meet the needs of every industry, while staying ahead of the curve in power generation trends.

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.

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.
