How to learn how to sew on overlock</a>

The overlock device, in contrast to the sewing machine, implies the presence of three or four strands.

To deal with all the threads and get a straight line of good quality, you have to spend a lot of effort ...

At the first acquaintance with overlock it is necessary to giveGreat attention to its operation manual, where you can find a refueling scheme. Also there, in great detail, describe the purpose of all adjustments and their location. Many manufacturers indicate the recommended values ​​for obtaining quality stitches. If you did not manage to get acquainted with the instruction for any reason, you should be patient and start experimenting.

First you need to prepare an overlock, thread andmaterial. And the threads must be of the same quality, but of different colors (this will be easier to understand). Material to begin with, you need to take a simple (not knit, not too thin and not too tight). Is better for calico or something like that.

Next, after the correct filling, you need to setAll thread tension regulators to an average value, usually 3 or 4, and sew a small distance, the stitch can be far from ideal. You can compare it with a line on an already finished product, for example: T-shirt, T-shirt, etc.

And now let's start to understand the adjustments. Try twisting one of the thread tension adjusters (clockwise - increasing - counter-clockwise - decreasing). Look at the resulting line. If you have increased the thread tension, the thread should pull the material out more. If decreased, then the thread will be more free to lie in the line (looping). For yourself, note which thread in the line corresponds to this adjustment. Return the tension to the previous (average) value and repeat the experiment on the other controls. In this way, you can determine the optimum settings by looking at each tensioner in turn.

In addition to adjusting the tension of threads in the overlock there isAdjustment of stitch density, edge trimming and differential feed. Density adjustment - changes the amount of material advancement per shot. By adjusting the edge trim, you can achieve better fit of the threads to the cut edge. But the differential feed adjustment adjusts the progress of the material, while adjusting the assembly and stretching of the material. The average value of this adjustment is 1 (it is better to leave it on the unit until then until you figure out the rest of the settings). If you need to do material assembly, then the value is set greater than one. The value is less than one (most often used on knitwear) is placed in those cases when the material needs to be stretched (give a reserve for stretching).

Once you understand the purpose of all adjustments and each of them will be tested in different versions, it will not be difficult to adjust the line as well as on the factory product.
