All about Merrylock rugs

Modern Merrylock carpet locks can provide a confident answer to all the challenges faced by this technique. But to get a good result, you need to make the right choice. And not only take into account the nuances of each model, but also pay attention to possible problems.

It is appropriate to start the review with modification Merrylock 5000, which is equipped with a switchable upper knife. This model has a well-thought-out illumination of the working area. Along with chain stitching, you can also use the flat stitch with three needles. Bottom and chain loopers allow threads to be loaded automatically. There is a flatlock mode.

The width of the stitches ranges from 0.1 to 0.9 cm. Their width is from 0.1 to 0.4 cm. The current consumption will be 0.1 kW.

Deserves attention and five-thread carpetlock Merrylock 5550A. The model can make flat seams. Thanks to the automatic thread tension, work is greatly simplified. The waste container makes it easier to keep the workplace clean. The stitching quality will be almost professional. Sometimes flatlock, cover-stitching and rolled seams are used; color coding and differentiated feed are provided.

The scope of delivery includes a foot pedal and a transport handle. Stitch widths vary from 0.2 to 1 cm.

Another five-line apparatus - Merrylock 007. The maximum stitch width is 0.7 cm. The design allows for 21 stitch variations. Stitch length ranges from 0.1 to 0.4 cm. You can use a rug for a cover seam, flatlock seam.

The 2015 model also attracts attention Merrylock 0115A. A feature of the modification is free sleeve. The LED system has a lifespan of 10,000 hours. The distance between the needle and the bed is 0.1 m. The tension of the threads will have to be controlled manually, without the help of automatic equipment.

Technical specifications:

• stitch length from 0.1 to 0.5 cm;
• stitch width from 0.2 to 0.9 cm;
• the height of the raising of the foot - 0.5 cm;
• 1300 stitches in 60 seconds;
• current consumption - 0.1 kW.

In 2015, another five-line model appeared - Merrylock 075. It also has a free sleeve function. The service life of the backlighting LEDs is at least 10 thousand hours. It is required to control the tension of the threads manually. You can turn off the thread trimming knife; the package includes a soft case.

Five-thread carpet locks can sew 2-, 3-, 4-thread seams in the same way as 5-thread stitches. The classic double thread stitch is needed to work with very thin materials. Since in most models, each line is made with at least three threads, for such work you will need special converter.

Three-thread seams are most often used. This technology is very well established and economical. It can be applied to any fabric. Four thread seams allow you to combine overcasting with sewing fabric cuts. This approach is also acceptable for stitching knitwear.

Four threads will allow you to work and stretch fabric. The pinnacle of perfection - 5-thread stitching - requires the use of three needles at once. This method is good for capricious, unstable tissues. It is useful if you plan to sew in a zipper or a large brooch. Ornamental seams, which can also be created with Merrylock rugs, take a special place.

Roll (sometimes roller) pass requires adjustment of the thread tensioner. The trimmed edge appears to be curled inward. Therefore, it will be possible to make a frill with a wavy surface or increase the elasticity of the edge of the garment. Role seams are actively used in the manufacture of concert, dance and theatrical costumes.

The flat seam - flatlock - is produced only on rather expensive models. But there is a way out: the use of flat line imitation. If you don't look closely, there won't be much difference. Flat seams help hem the bottoms, sleeves and leg of the garment. Also this method allows:

• trim a cut of thin fabric;
• grind down jersey;
• cut off excess matter.

The Merrylock 007 is considered inexpensive and at the same time quite functional device. The reviews mark his good line. However, the speed of work is not high enough for sewing duvet covers and other large items. Changing threads when switching from overlock to cover sewing is difficult. The machine runs quietly, but the carpetlock knife may jump intermittently.

The 5550A can sew flat and overlock without special settings. Reconfiguring between types of seams with the right skill is not difficult. Experienced seamstresses will be able to fully master the system in 2 days of intensive work. There is practically no noise. Even overheating from an incandescent lamp is easily eliminated after replacing it with an LED lamp.

Model 0115A is a well-stocked rug. Despite the lightness of the device, it takes up a lot of space. At the same time, however, it works quietly and rather quickly. To work with a braid, piping and decorative ribbons, you will need special paws. Otherwise, there are no particular complaints.

Sometimes there are complaints that the rug is tearing the thread and twisting. Such problems can happen on any car make and model. Reason - mishandling... For example, when the needle is not inserted all the way or it comes into contact with the walls of the hole. Another such problem may be related to:

• with the absence of a compensating spring on the tension regulator;
• with the thread catching on the bobbin case adjuster;
• with a very weak upper thread tension;
• clogged cap;
• using unsuitable parts;
• with general wear and tear on the carpet.
