Loop formation
A method of forming slotted loops supported by a machine.
—
Automatic. Fully automatic buttonhole sewing mode; 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; It is the automatic method that is recommended if you plan to sew a large number of loops.
—
Semi-automatic. When forming a loop in this way, the work is done in 2 or 4 steps. For example, in the first case, the machine makes one short bartack and one long longitudinal stitch in one pass, then the mode switches and a second bartack and a second long stitch are performed; in the second case, accordingly, you have to switch between 4 stages. Such work takes more time than automatic loop formation, but such machines are cheaper.
Number of loops
The number of welt stitches that a sewing machine can make. Different types of loops are used for different types of fabrics and clothing. The larger this number, the wider the choice the user has and the less likely it is that the machine’s arsenal will not have the required type of loop.
Max. stitch width
The maximum stitch width provided by a sewing machine.
Most modern sewing machines are capable of working not only with the simplest longitudinal seam (when punctures with a needle occur strictly one after another), but also with seams that cover a certain width - for example, zigzag and various decorative ones. And in overlockers, such opportunities are generally available by definition.
The larger the maximum stitch width, the correspondingly wider the machine’s ability to work with specific types of seams (all other things being equal). An indicator of up to 5 mm is typical mainly for entry-level devices, 5 - 7 mm - average, 7 mm and more - advanced.
Presser foots
Types of feet supplied with the sewing machine.
— Universal. A foot 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 overlock, but in some situations it allows you to do without it.
—
Upper fabric conveyor. 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.
—
Foot for sewing in a zipper. 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.
—
Foot for decorative stitching. 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.). Anyway, the stitch line sh
...ould usually strictly follow the contour along which it is applied — and this contour can consist of both straight lines and curved lines. Special foots 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 stitch 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, 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.
— Foot for sewing on buttons. A foot 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 package — for example, for satin stitching, for processing sections, etc.
