Is the Singer 191D-30 the best Singer industrial sewing machine? This review will take an in-depth look into the machine so that you can find out.
The Demands of Bulk Sewing
You should understand that conventional sewing machines cannot reliably handle the demands of bulk sewing that involves heavy fabrics. Even for light fabrics, you cannot depend upon domestic sewing machines for continuous sewing operations that last for several hours each day. If you try to push your domestic sewing machine to the limit, you will soon notice funny sounds. These sounds would be the machine groaning under the load. There may also be a burning smell and the motor will eventually burn out if you persist. The motor is not powerful enough for heavy operations. It also lacks the special lubrication system that is required for the motor to work for long hours.
So, for heavy fabrics, long operations and ultra-high stitch speeds, you need to use the best Singer industrial sewing machine.
Key Differences Between Industrial and Conventional Sewing Machines
Although they might look rather similar superficially, industrial sewing machines are different from home sewing machines in several ways. Since industrial sewing machines are built for long term use, bulk output, and professional use, they are constructed with superior quality parts, motors, and stands. Since traditional sewing machines are built for light use, they can even include plastic gears and parts. On the other hand, industrial sewing machines will use aluminum or cast iron for its housing, connecting rods, gears, and body. These construction details make industrial sewing machines sturdy options, not just for the mass production of apparel but also for shoes, bags, sofas, seats, car upholstery.
Since the stitching mechanism must be enduring and dependable, industrial sewing machines are often for just one stitch type. In most cases, it is the basic straight stitch for simple straight seams. There are also models for sewing different types of stitch patterns such as the zigzag seam. There are even industrial sewing machines that are specialized to just sew and produce buttonholes. Conventional machines offer several stitch varieties.
Standard sewing machines often operate at a power of around 65 Watts. Heavy-duty sewing machines often have a motor that is around 60 percent more powerful than the standard variety. This means that heavy-duty sewing machines can take up around 100 Watt power and their stitching speed can go up to 1,200 stitches per minute. These figures are dwarfed by mighty industrial sewing machines which operate at 400 Watts. It is not uncommon to have stitch speeds of 4,000 revolutions per minute. This speed can go up to 5,500 stitches per minute and even higher. Since such speeds are comparable to the rotational speed of your car engine, industrial sewing machines require specially designed self-lubrication system to minimize friction and wear. Special attention must also be given to minimize the noise levels since the motor operates at very high speed and power.
Types of Industrial Sewing Machines
On the basis of the arm design and needle post, there are basically four types of industrial sewing machines:
Flatbed
This is one of the most common varieties. Flatbed-type industrial sewing machines closely resemble ordinary sewing machines since the needle and arm extend towards the machine’s flat base. The flatbed type sewing machines are typically used for sewing together flat fabric pieces. This is the category to which the best Singer industrial sewing machine belongs.
Cylinder-Bed
These sewing machines employ a horizontal and narrow column in contrast to the flat base. Fabric can, therefore, be passed under and around the column. The cylinder-bed diameter lies between 5 cm and 16 cm. This machine is commonly used for mass production of cylindrical items like shirt cuffs, as well as bulkier items like shoes and saddles.
Post-Bed
These industrial sewing machines feature a vertical column that has loopers, feed dogs, and bobbins. The vertical column rises over the machine’s flat base. The column’s height can lie between 10 cm and 45 cm. The post-bed machine is utilized for those applications where access to the sewing is restricted such as boot making, glove making, and attaching emblems.
Off-the-Arm
In this type of industrial sewing machine, the material is fed by workers in line with the horizontal column’s axis. This type is used in applications like shoulder seams and sleeves.

Generous Sewing Area
The sewing area is extra-large so there will be no shortage of space and no overcrowding. This can be an annoying factor for conventional sewing machines. You can now easily manage bulk output and large projects, thanks to its extra-long 11.75 inch-arm of this machine.
Presser Foot Pressure Can Be Easily Adjusted
You can readily adjust the pressure that the presser foot applies to the fabric. By just turning the dial, you can customize the pressure. This will allow you to sew all sorts of fabrics including the heaviest denim and the lightest tricots.
