Industrial Sewing Machines

Industrial sewing machines are available in a number of types, the four main types are: flatbed, cylinder-bed, post-bed and “feed-off-the-arm” machines.

ACG Nyström AB supply 1-needle industrial sewing machines, 2-needle industrial sewing machines and multineedle industrial sewing machines such as zigzag, bartacking, overlocks, safetystitch, coverstitch, chainstitch and others for men’s and women’s wear, upholstery, car interiors, awnings, tents, canopies, tailors, filters, curtains, shoes, lampshades, saddlery and orthopedics.

Industrial sewing machines are available with a variety of stitch types, each requiring between one and seven threads. The most common are the lockstitch, chain stitch, overlock stitches and coverstitch. Lockstitch, stitch type 301, is probably the most common type of stitches. In everyday terms this seam is called straight or plain stitches.

It is important to find the right machine for your production in order to achieve the best results.

When you buy an industrial sewing machine from ACG Nyström, you can be sure that you get a machine that is tested and approved by our very high standards, both in terms of quality and technology. All machines that we sell are CE marked.

We customize the industrial sewing machine for your needs.

Things to consider when buying an industrial sewing machine

Before buying an industrial sewing machine there are a few things to consider, so you get the best machine for your needs.

What is an industrial sewing machine?
Industrial sewing machines differ from traditional sewing machines in many ways. An industrial sewing machine is specifically built for long term, professional sewing tasks and is therefore constructed with superior durability, parts and motors. Whereas traditional sewing machines might include nylon or plastic gears, an industrial sewing machine’s gears, connecting rods, housings and body are typically constructed from high-quality metals, such as cast iron or aluminum.

Different types of industrial sewing machines
There are four main types of industrial sewing machines. The differentiation between them is based on the design of the arm and needle post. These four types are:

Flatbed:
The most common type. These machines resemble traditional sewing machines. The flatbed machine is mostly used for sewing flat pieces of fabric together.

Cylinder-bed:
These machines feature a narrow, horizontal column as opposed to a flat base. This allows fabric to pass around and under the column. The diameter of the cylinder-bed varies from 5 cm to 16 cm. The cylinder-bed machine is used for sewing cylindrical pieces such as cuffs, but it is also useful for bulky items such as saddles and shoes.

Post-bed:
These machines feature bobbins, feed dogs and/or loopers in a vertical column that rises above the flat base of the machine. The height of this column ranges from 10 cm to 45 cm. Applications that make access to the sewing area difficult, such as attaching emblems, boot making and glove making utilize the post-bed machine.

”Feed-off-the-arm”:
The least common group, these machines require workers to feed material along the axis of a horizontal column. The design limits the length of the seam sewn to the length of the column, but is useful for applications such as sleeve and shoulder seams.

Things to consider when buying an industrial sewing machine
After you have determined which type of industrial sewing machine best fits your needs, the next step is to choose how many and which type of feed mechanism you should purchase. Different industrial sewing machines offer several ways to feed the material. Industrial sewing machines that deliver numerous feed capabilities are usually more expensive.

The main types of feed mechanisms are:

Drop feed:
The feed mechanism lies below the machine’s sewing surface. This is probably the most common feed type.

Needle feed:
The needle itself acts as the feed mechanism, which minimizes slippage and allows workers to sew multiple layers of fabric.

Walking foot:
The immobile presser foot is replaced with a foot that moves with the feed, which allows easier performance on thick, spongy or cushioned materials.

Puller feed:
The machine grips and pulls straight-seemed material as it is sewn and can perform on large, heavy-duty items such as canvas tents or for very thin materials, such as thin curtains.

Other things to consider
The application of an industrial sewing machine is also an important factor to consider. For example, some machines come with automatic functions, while others include pattern programmability. Furthermore, the strength and design of the machine needs to complement the type of material you will be using. Higher quality machines will likely be necessary for medium to heavy materials, while base level industrial machines may be adequate for lighter materials.

The stitch type should also be considererd before buying an industrial sewing machine. There are a variety of stitch types, each requiring between one and seven threads. Straight or plain stitches are the most common for industrial sewing and include lockstitch, chain stitch, overlock stitches and coverstitch.

Another important feature to look into is the size and speed of the industrial sewing machine. More expensive machines will be able to sew more stitches per minute. Larger machines provide a larger clearance area under the foot and bigger bed size. You will need to ensure that the size and speed of the machine you purchase will meet your needs and expectations.

Welding

Instead of sewing the material together, it may be joined by welding. The welding can be done with hot air, hot wedge or ultrasound. Ultrasonic welding or glueing by ultrasound provides a strong and very durable joint and is especially useful when you want to avoid holes from a sewing machine needle. Industries where welding of materials is used include the industries of awnings, blinds, sails, canopies, filters and non-woven materials.

Ultrasonic

Joining materials by using ultrasound is a fairly new technology. Ultrasonic welding or glueing by ultrasound provides a strong and very durable joint and is particularly suitable for products where you want to avoid holes from a sewing machine needle.

Examples of this are:

• Awning manufacturing
• Filter manufacturing
• In healthcare
• In the clothing industry
• Tents and sleeping bags etc, which must be watertight
• Sails
• Canopies

In the clothing industry, welding and glueing by ultrasound becomes more and more usual. Especially when it comes to the manufacture of underwear, sportswear, casual wear and outdoor clothing, the technology is used by many famous brands.

Joining with ultrasound provides a product design with more flexibility, efficiency and creativity. We work with clients in the industries of awnings, blinds, sails, canopies, filters and non-woven materials.
