What is different from the serger sewing machine: the main differences

Sewing machine - the equipment that produces the crosslinking density materials. Overlock - a sewing machine, which processes the edge of the non-standard fabrics to prevent unraveling yarn material. Each single unit can play only one kind of suture from conventional straight stitch decorative and finishing lines. A common feature of these stitches - elasticity, which allows you to work even with the tissues of the jersey. Preferably the presence of the rack, which is in the process of working with delicate materials slightly stretches the fabric, allowing the playback of more accurate and high-quality welds.

The main differences from the overlock sewing machine

The main difference from conventional overlock sewing machine - instead of shuttle parts two looper installed, which perform its functions. As an addition to it there are two knives, top and bottom, are responsible for cutting and processing of the edges of the product.

The device current overlokov made it possible to remove the blades when required, only the fabric sheathing. Including some models installed two pairs looper that can reproduce joints of the four strands. In operation can disable one, two or three looper immediately, depending on whether any of the number of threads need to receive the seam.

Overlocks also differ in appearance weaves mind. From loopers it depends on how the threads are interwoven with each other, and how many lines will subsequently every seam. Every seam is produced by one particular looper, but there is a blanket stitch of three strands, in which both looper involved. It is designed to handle bulk materials.

Miniature reed weaves the threads, thus being responsible for the width of overlock stitches. If it is removed, it is possible to obtain three thread hem whose width does not exceed 2 mm. In addition to the tongue can be set small metal bracket to the upper looper, which brings the lower thread to the needle, helping to form two interlacing thread. Dressed thread once the needle and lower looper.

Important! Overlock may differ from the sewing machine, the number of necessary threads. That is, if overlock uses five threads, the sewing machine copes with only two threads.

Overlock uses thread so that they do not break during processing of the material. This possibility appears because of the direction of the filaments is not in itself the bobbin, and once in the spool loops. As a result, blanket stitch turns out strong and capable of stretching. The length of each stitch is increased, and subsequently the thread spent not so sparingly, as would occur with a sewing machine.

Can a serger sewing machine to replace?

By itself, the serger comes as an addition to the sewing machine, increasing the functionality of its capabilities. But it is worth noting the fact that without it, it can work well. And so it was, until recently, because Overlock almost did not appear in the shops, and knew of its existence only a handful of professional seamstresses.

A sewing machine is designed to connect the edges of the fabric. But, even if slowly, it can handle the edge of dense materials. In the case of fabric, such as chiffon, it is better not to use, as the inevitable appearance of stretch marks and defects.

What is a serger sewing machine

If a person does not plan to engage in professional tailoring, then acquisition overlock not really necessary. Some sewing machine models have built-in program reproduction hem on certain materials. It will handle edge products, and generally improve the quality of the welds. The existence of this program is better at once interested in buying a sewing machine. But sometimes, the manufacturer itself provides a description of such features on the unit.

Sometimes, complete with a sewing machine is overlock foot. But to buy it separately if the unit provides for installation. It can not be a full replacement, but can help combine the two devices in one, providing a sewing machine of the overlock functions.
