carver Whether you are an amateur or a professional in sewing business, when you start sewing almost immediately the question arises of using auxiliary equipment other than a sewing machine. In particular, we are talking about a machine whose ability is the processing of tissue from the torpor. And not only because when sewing products from elastane, its use is indispensable. However, fortunately, at the present time, it is not a problem to purchase such equipment both in hardware stores and in highly specialized stores.

If you had to choose, then an overlock and a coverlock will certainly be presented to your attention. This is where the question arises: what is better to choose and how do both devices differ from each other? Now we are faced with the task of finding out: coverlocks and overlocks, what's the difference?

The main purpose of the

Overlock, perhaps the familiar word, is a technique that is intended for the purpose of wrapping the fabric, and at the same time, during operation, cuts off extra strips of matter. In professional sewing it’s just an indispensable thing, and having such in your home arsenal for amateur sewing is a great luxury. After all, it can be used to achieve high-quality tailoring. It is suitable for overcasting various types of fabrics and textile fabrics.

Koverlok, also essentially the same overlock, only with advanced features. Coverlock can be called a combination of overlock and spreading machine. He can sweep over almost all types of fabrics. And its main difference is that it easily copes with knitwear. That is, it is a feature through which it is predominant over the overlock.

Thanks to a special function, it easily covers the knitted fabric by applying a smooth, flat( embroidered) seam. This feature gives it a great advantage, since the use of elastic, knitted fabrics in the process of making various products is very common.

Structural differences

If we talk about external differences, they, of course, occur in both devices. These are:

  • special( cantilever) sleeve;
  • number of loops.

These two details distinguish them from each other in appearance.

Console compartment( sleeve)

In the overlock structure, this part of an insignificant size is almost absent. This is due to the fact that its function is reduced to the processing of fabrics, parts of products that are previously prepared. That is, it comes down strictly to overcasting the finished elements.

Overlock has a significantly larger cantilever sleeve area. This is dictated by the specifics of the application, because such devices, as a rule, are used by professionals, in particular, in specialized shops, factories, working with complex products.

The number of loops

This moment, which eliminates the need to wind the spools. The so-called progress in this compartment.

Overlock has two loops. During the work two, three or five threads at once can be involved. Which way you need in a particular case, adjust yourself.

Coverlock is equipped with three loops at once, among which two actually perform an overlapping function. Koverlok under force to carry out process with involvement at once ten threads. However, in any case, you yourself choose the required amount. The regulation of this process occurs with a switch.

Functional Differences

Overlock is designed specifically for overcasting, and copes very well with this. Especially indispensable in the processing of "loose" fabrics that when pruned can quickly rasprashivatsya.

Overlock works on the principle of pressing simultaneously at the same time several threads of a cut-off edge and quick brushing. This is a reliable way to sweep the product for the first time.

Corner is able to do all this. He also successfully cope with tissues having a loose structure, and not only. The main advantage of the device is in its ability to perform a cross-link knitting fabric processing method - a flat seam. As well as a special processing method successfully copes with the finish of the neck and the like.

Cons of

It would seem how such an effective device may have disadvantages. However, there is no perfect technique. Therefore, if there is an advantage in one thing, then in the other one will surely find at least insignificant, but minuses. Let's call them:

  • High price. So, the cost of a carpetlock is indeed much higher than the cost of an overlock. Moreover, at such a cost you can purchase two independent pieces of equipment, for example, an overlock and a spreader, and those sometimes will cost less than a coverlock.
  • The complex principle of operation. Despite the achievements, working on such a device is quite difficult. To begin with, it should be well understood, and then work out in practice. Especially working with knitwear requires fairly fast maneuvers with shifting speeds. It should be noted that even experts in sewing equipment recognize the principle of work difficult.
  • Great weight. Modern coverlocks can be improved by a number of new processes and mechanisms, because of which its weight will be quite large. All these additional functions are sometimes not even used in the process of work, and significantly complicate the process of device setup and operation.

We considered the difference between overlock and carpetlocks based on the main characteristics and we can draw certain conclusions. It is impossible to unequivocally say which device from both is better. Probably, it follows from the needs, opportunities and wishes for such an aggregate. The main thing is to correctly navigate with respect to the properties and basic functions of the technology, and making a start from this, to make the right choice. Own right choice.
