The type of sewing machine shuttle.

The shuttle is a device for feeding the lower thread. It is in it that the spool with the thread is inserted. In modern machines there are such types of shuttles:

— Oscillating . Oscillating shuttles have only a vertical layout. It is a simple, inexpensive and at the same time reliable mechanism, which also makes the device practically “omnivorous”: many models with oscillating shuttles can cope with thick coarse fabrics that are “too tough” for other types of machines. In addition, in such a shuttle, the method of thread tension is very simply regulated. Among the disadvantages of this option, it is worth noting an increased level of vibration and noise, a relatively low speed, as well as a more complicated threading procedure than in horizontal shuttles.

— Vertical rotary. In several features, such shuttles are similar to oscillating ones (see the relevant paragraph): in particular, they are relatively easy to adjust the thread tension, but to refill the bobbin, you must always climb into the mechanism and remove the bobbin case from the shuttle. The key difference is that the shuttle does not swing during operation, but rotates. Because of this, such mechanisms are somewhat more complicated and more expensive than oscillating ones. However, they provide a higher sewing speed with a lower level of vibration and noise. This option is...used in professional and semi-professional machines, as well as industrial equipment.

— Horizontal rotary. The shuttle of this type is easy to use: to thread the lower thread, one does not need to remove the bobbin case, just open the cover and install the bobbin directly into the hook. In addition, the top cover is often made transparent, which allows you to keep track of the rest of the bottom thread. At the same time, due to the rotational principle of operation, such a shuttle provides good speed and a minimum level of vibration and noise. Among the disadvantages of this option, one can note the difficulty in setting the thread tension: for this, usually, you have to unscrew a few bolts and remove the entire shuttle(whereas in vertical mechanisms the regulator is located on a quickly removed bobbin head). In addition, horizontal shuttles are not well suited for continuous sewing with coarse threads — such a thread can rub a groove in the case, after which the mechanism will have to be changed.

The method of loop formation supported by the machine.

- Automatic. Fully automatic loop formation; the user only needs to set the length, after which the machine will independently process the edges of the future loop, without the need to switch modes manually. The most convenient and advanced option; is the automatic method that is recommended if it is planned to overcast numerous loops.

- Semi-automatic. When forming a loop in this way, work is done in 2 or 4 steps. For example, in the first case, the machine makes one short bartack and one long longitudinal line in one pass, then the mode switches and the second bartack and the second long line are performed; in the second case, respectively, you have to switch between 4 stages. Such work takes more time than the automatic formation of loops, but such machines are cheaper.

The number of stitches that the sewing machine can sew. The larger this number, the more extensive the possibilities of this model and the wider the choice of the user. However, a specific range of supported stitches needs to be specified separately.

The least options — mostly up to 25 — are provided in electromechanical machines, as well as specialized devices like overlockers and coverlocks (see "Type"). In computerized devices, the number of stitches can be in the tens, and some also allow you to download additional options from your computer.

The maximum sewing speed provided by the sewing machine. In the vast majority of models, this parameter can be adjusted, so that, if necessary, you can sew at a lower speed.

The more stitches per minute the machine makes, the higher its productivity, and the better it is suitable for large volumes of work. At the same time, note that high speed has a corresponding effect on price and power consumption, and it is not always required. Detailed recommendations on choosing the optimal speed for certain types of work can be found in special sources.

— Alphabet letter embroidery. The ability to embroider letters of the alphabet using a machine. This function is found in computerized models. It is carried out due to a set of letters entered into the memory of the machine. Many models with this feature have several built-in fonts, and some even allow you to upload your fonts from your computer.

— Differential bottom feed. The fabric feed consists of two gear racks — in front of and behind the needle. Depending on the set mode, such a feed can additionally stretch or, conversely, collect fabric during sewing; the first is useful when working with dense fabrics, the second — for knitwear, stretch and other easily stretching materials.

— Reverse stitching. A function that allows you to switch the direction of movement of the fabric under the needle and, accordingly, the direction of the seam. Mainly used for stitching. The reverse is practically obligatory for sewing machines in the classical sense of the word — electromechanical, computerized and sewing-embroidery (see "Type"), but practically does not occur in other types.

— Free arm. A device for working with sleeves, trousers and other similar parts of clothing. This function is most often implemented due to the removable part of the desktop — when it is removed, the table turns into a narrow platform. The specific width of such a...device may be different, it should be specified separately.

— Needle threader. A special device designed to facilitate the process of threading a needle. The presence of a needle threader is especially useful when changing threads frequently (for example, sewing alternately with different colours).

— Thread cutter. A mechanism for cutting the threads after sewing, eliminating the need to use scissors: to cut the thread, just press the button. Note that we are talking about an automatic thread cutter; hand tools mounted on the bodies of some machines are not considered thread cutters in this case.

— Pedal free sewing. The ability to use the machine without connecting the pedal. To start and stop the process in such models, usually, a special button is provided. Such an opportunity can be useful for long sewing when it would be tiring to keep the pedal constantly depressed, and for occasional use, when the machine starts “for a couple of stitches” and there is no need to fiddle with connecting the pedal.

— Twin needle sewing. The possibility of using a machine for sewing with a twin needle — a pair of needles fixed in one holder. There are different types of such needles and different methods of working with them, and some work is done only with a double needle. Anyway, the use of such devices requires that the machine be initially compatible with them.

— Needle stop switch (top/bottom). A switch that allows the user to select whether the needle will be in the up or down position after the motor stops. In the absence of such a switch, the needle, usually, stops only in the upper position, and this is not always convenient

Types of presser feet supplied with the sewing machine.

— Universal foot. A foot is used for standard sewing, mainly straight stitches and zigzags.

— Overlock foot. A foot designed for overlocking. By definition, it is found in devices with an overlock function (see “Type”). However, it can also be provided in traditional sewing machines. In the latter case, such a foot, of course, will not replace a full-fledged overlocker, but in some situations it allows you to work without it.

— Top feed or walking foot. An additional top-mounted feed dog in place of the stock foot, in addition to the standard bottom feed dog. Such a device makes it easier to work with thin, delicate and sliding fabrics, as well as sewing together several layers of fabric: the material moves as evenly as possible, without distortions and displacements.

— Zipper foot. The foot for sewing in a zipper can have a different size and design — in particular, there are special devices for sewing in a hidden zipper. The specific features of this device should be clarified separately.

— Decorative stitch foot. Feet designed for various types of decorative stitching. Such a line may not have a functional role. Its main task is to emphasize a certain element of clothing (edges, pockets, individual seams, etc.). Anyw...ay, the stitch line should usually strictly follow the contour along which it is applied — and this contour can consist of both straight lines and curved lines. Special feet for decorative stitching simplify the task: they are equipped with rulers or other devices that allow you to control the parallelism of the stitches.

— Satin stitch foot. This foot will be suitable for appliqué and other work where zigzag stitches are often used.

— Blind hem foot. Foot designed for blind seams used when hemming the edge of the fabric. It is equipped with a device that provides a hem of the fabric and in this position feeds it under the needle.

— Quilting foot. Special feet for quilting — patchwork. In such works, it is necessary to sew the fabric in several layers, as well as to perform figured seams. In extreme cases, you can use the usual universal foot for quilting, but using a special device is still much more convenient.

— Monogramming foot. The foot for embroidery of monograms will allow you to make embroidery on any object, thereby decorating it with your signature or the emblem of any institution, company, or sports club.

— Buttonhole foot. Buttonhole foot. It eliminates the need for manual work. The sewing machine will do everything for you, which will reduce your time and please you with quality.

— Button sewing foot. A foot is designed to hold the button on the fabric while sewing on. It has a special protrusion pointing down: when the main part of the foot is pressed against the button, this protrusion presses the fabric and prevents it from slipping.

In addition to the above, other types of feet may be included in the delivery kit.

The power consumed by the machine during operation. Usually, the maximum power value is indicated in the characteristics.

Most of the electricity supplied to the machine is consumed by the engine, so this indicator primarily describes the power of the engine. The higher this power, the faster the machine can work and the better it is suitable for working with dense fabrics. However, there is no strict dependence here, much also depends on the general specialization of the unit.
