In this article we will tell our readers about what the modern household sewing machine, carry out the classification, compare the proposed market model cars, will talk about what can be done with different types of machines. I want to warn that this article does not discuss sewing and embroidery machines, the cost and the possibility of which is very far removed from even the most complex sewing machines. The choice of these machines in a separate article.
Ancient grandmother’s machine “Singer” was able to do a straight stitch. Later, there were machines, in which a needle can be moved from side to side and changed the design of the shuttle. These machines are able to portray more complex and zigzag lines. Number of lines in the most sophisticated and modern machines only limited imagination of the developer.
According to the principle of building lines, modern sewing machines can be divided into mechanical and computer-controlled machine; and this is the first we must decide what to buy.
Mechanical Sewing Machine
The mechanical sewing machines for the movement of the needle and the movement of the fabric conveyor gear meet the special form and all sorts of levers, wheels and other mechanics. Machines with mechanical control, in view of the technological features can not perform complex shapes and lines have a limited number of lines.
Here, perhaps, the most complex and functional representatives of this type of machinery:
Pfaff Select 4.2
Husqvarna Viking Eden Rose 250M
Family Gold Master 8124e
New Home NH 5631
The computer-controlled machines, moving the needle relative to the tissue controlled by a microprocessor. This principle of control removes restrictions on the complexity of the lines and their quantity. Everything is determined by the memory capacity and the program, which the manufacturer laid down in a particular model.
Only computer-controlled machines can perform a loop with “eye” and beautiful decorative stitches.
However, whatever the principle of the line, its width is limited by the design of the shuttle and move the needle outside. The best machines stitch width is 9 mm (Pfaff Performance 5.0, Pfaff Expression 4.2, etc.).
For wider lines requires tissue displacement mechanism not only forward and backward, and right and left. With such a fabric can be moved in several directions mechanism and despite the absence of the embroidery unit, these machines can be called embroidery sewing machines with capabilities. Rate these features can be at embroidery, such as borders of decorative stitches. Embroider flower can make several stitches diagonally, embroider any asterisk, make several stitches in the other direction and so on. Thus, you can get the most intricate patterns of arbitrary size (sometimes in advertisements such patterns are called “maxi-patterns”).
For sewing machines the ability to move tissue from side to side – exotic. So far, only the company Pfaff, Brother and Husqvarna are using this technology in some expensive models. For example, we can mention the car Husqvarna Viking Sapphire 960Q.
Number of lines of modern machines range from simple mechanical units, up to several hundred in complex computerized machines. The lines of the sewing machine can be divided into working and decorative.
By working the lines include, in addition to the traditional straight stitch and zigzag, as overlock stitch, stretch fabrics, hidden stitch, quilting, etc. The following table shows examples of useful, in our opinion, the working lines:
Elastic zigzag sewing gum
Stretch stitching for jersey
Reinforced straight stitch
The line for invisible hems
Elastic stitch for invisible hems
Almost all electromechanical machines can perform a clothesline welt loop. Some machines do a loop in semi-automatic mode in four stages without turning the fabric – the left side of the buttonhole, distant tie, buttonhole on the right side, and finally, the near tie. Many of this class of machines allow to perform the loop automatically according to the size of the buttons. Other types of loops available for electromechanical machines.
Machines with computer control make the loop in the automatic mode. Machinery Japanese companies typically perform loop in accordance with the size of the button – this button is inserted into a special measuring device. European cars do not usually have a measuring device buttons – in such machines, you can specify the desired size of the loops in millimeters. For dimensional accuracy Pfaff and Husqvarna Company loop supply their machines device measuring loop itself in the buttonhole. Computerized machines are able to perform up to 10 or more kinds of loops. In addition to the traditional linen this can be costume loop, eyelet, loops knitted loop with rounded edges and others. In addition, once you can make a loop and enter its parameters in memory – on the machine will make any number of absolutely identical loops.
Even an ordinary clothesline loop many computerized machines do not like electro. First laid straight stitch on the left side (line mimics the cord – in the best loops made on professional equipment), then zigzagged are deposited this side, then are deposited tack, and then again a straight line on the other side, the other tack, zigzag are deposited right side and in conclusion – a few tie-off stitches point. Total – 7 receptions.
The range of decorative stitches have limited mechanical machines. Perhaps the biggest set of lines among this class of machines can be found at the Pfaff Select 4.2 and New Home NH 5631.
All computer-controlled machines can perform a variety of decorative stitches. This choice of patterns, scalloped undercut, satin stitch made enveloping the simplest elements of embroidery – cross stitch, openwork, delicate lines and so on. In complex patterns, one or more scripts stored in memory. Many current models (eg Husqvarna Sapphire 930) have in their arsenal is not only English, but also Russian alphabets.
Generally, any line can be modified by changing the stitch length and width. Sophisticated computer machines have the function of mirroring the horizontal and vertical lines.
Some computerized machines have a memory in which you can enter certain combination of letters (for example, names of family members), or a sequence of decorative elements to embroider them in the desired order.
Rare models are equipped with a function to create your own decorative stitches. You can simply draw a line on the screen of the machine, and then sew it! Such a possibility is, for example, the Pfaff Performance 5.0 and Husqvarna Sapphire 960Q.
Shuttle modern household sewing machine for sewing or oscillates, or rotates in a horizontal or vertical plane. Accordingly, the shuttle is called “rocker”, “horizontal” and “vertical double obeganiya”.
The oscillating shuttle hook (oscillating) the shuttle is the easiest. Many he knew for domestic sewing machines “Seagull”. This hook is used by all manufacturers in low-cost electromechanical machines. The disadvantages of this type of shuttle considered increased vibrations during operation, lower the sewing speed, stitch width limitation (no more than 5mm) and the highest quality lines.
Horizontal Horizontal hook hook double obeganiya is the most common type of shuttle cars in cost from $ 250. This shuttle is most convenient for filling bobbins. Bobbin of this shuttle is visible through a transparent window on the needle plate. This is handy because you can easily estimate the amount of remaining thread on the bobbin. Machines equipped with such a hook vibrate less, as the shuttle rotates rather than swinging. It should be noted that the machines with shuttle significantly less entangled bobbin thread. Horizontal hook does not require lubrication. The disadvantages of such a shuttle may include uncomfortable adjust the bobbin thread tension – in order to reach the adjusting screw it is necessary to remove the needle plate.
Vertical canoe double double vertical hook obeganiya obeganiya used in the construction of expensive electromechanical sewing machines Pfaff production. Shuttles similar design used in professional sewing machines. The main advantage – high reliability. Machines equipped with a hook so as to vibrate less in comparison with low-cost designs and also reduced the likelihood of tangling up the bobbin thread. An important advantage of such an arrangement to the horizontal hook is easy to adjust the bobbin thread tension. The width of the zig-Zag machines equipped with shuttles from this design significantly limited.
To achieve good weld it is necessary that the upper and lower thread interlaced in the thickness of the material rather than on its surface. Ensuring the correct weave yarn tension control is achieved. The needle thread tension is usually changed by a special control on the front panel of the machine. Average position controller is sometimes referred to as “auto” and corresponds to the most commonly used tension. Some machines have a computer device which automatically tension depending on the chosen fabric and stitching.
To adjust the bobbin thread tension is a special adjustment screw on the shuttle.
Foot pressure on the fabric
For serious sewing machine desirable pressure adjustment tabs on the material. To obtain high-quality stitching and adjust the stitch length on the normal tissues it is necessary to provide high pressure, while the pressure must be reduced jersey to avoid stretching the material.
The electromechanical machines provided with a special pressure spring. Some machines provide special regulator spring force and, accordingly, foot pressure on the fabric.
In complex computer-controlled machines are sometimes provided for the automatic pressure adjustment and a special control over its persistence.
For machines equipped with upper conveyor tissue presence of the pressure regulator is not required. High quality lines provide riding conveyor.
On the possibility of flash very thick material machine designers also made sure – maximum foot lift up to 12 mm.
The drive power and puncture force, variable speed control, and sewing.
The mechanism of the sewing machine is driven by an electric motor. The cheapest electromechanical machines commonly used AC motor 220V. More expensive machines are equipped with low-voltage DC motor. The most sophisticated machines can contain several electric motors.
On machines with AC motor puncture force depends directly on the sewing speed, which of course is not convenient. To the machine can easily handle any fabric thickness and density electronics must ensure the maximum force with which the needle has to pierce the tissue regardless of engine speed. For this purpose, the machine is designed to be an automatic control efforts needle puncture. With this device a modern sewing machine can sew thin fabrics gently and easily cope with the thick rough and layered seams, such as denim.
Often, when choosing a car, buyers are guided by the value of the power specified on the machine, assuming that the greater the value specified, the more dense and thick fabric will sew machine. This is partly true of the cheapest cars, but for more complicated much more important to have an automatic adjustment efforts puncture. In addition, the value indicated on the housing total power consumption of the mechanical power which accounts for just over half. Be that as it may, the maximum mechanical power machines have traditionally been produced by European companies – Pfaff and Husqvarna.
Keys mashinoySkorost sewing sewing – an important characteristic of the sewing machine. It is governed by the power pedal. Many sewing machines cost from $ 300 provides a smooth limit the maximum sewing speed.
The machine Brother QS series, as well as in some models and Husqvarna Janome provides for the possibility sewing without using the pedal – to start sewing, you should click on the special button to stop the machine – press again.
Some machines are equipped with a special button lift and lower the needle. Another very handy feature – the needle stop in the up position. If you are using a machine equipped with this function, you will not have to turn the handwheel to bring the needle to its highest position – the needle will always stop at the top of itself. Sometimes the needle position at the time of stopping can be programmed and the machine will stop the needle in the down position, which is useful when quilting or during processing, such as lapels.
What is included
Included with the machine is normally supplied mass of a variety of accessories – a set of needles of different thicknesses, the needle with a rounded tip for jersey, double needle, screwdriver, brush and other tools for the maintenance of the machine, and of course a variety of tabs.
Often in the kit can be found for the straight stitch foot, decorative stitch foot, buttonhole foot, to the invisible hems and overlock stitches, sewing buttons and zipper. The most complete variety of accessories kits usually come with the machines cost from $ 300.
But feet for sewing and special equipment, there are so many that provide all of them with the machine impossible and useless. Tu foot that suddenly needed, can be purchased at any large store that sells sewing machines. There are special tabs to perform tucks, pleats, assembly, sewing different lightning to undercut, for coarse fabrics, for loops and buttons for hiding stitches and buttonhole with simultaneous cutting edge for sewing on cord, or even several, quilting and patchwork, and many others. We recommend each customer to purchase a sewing machine and a set of spools very comfortable sewing foot concealed zipper.
Husqvarna and Pfaff Company in the box with the machine put a special catalog of accessories that can be purchased for a sewing machine. For machines other manufacturers accessories catalogs can be found on the Internet. In Moscow shops the most widely represented legs and accessories for Husqvarna, Pfaff, Janome, and Family. For other cars the choice is not as rich, but the most popular tabs on sale there.
Sewing Advisor in many modern machines with computer control system has help and tips for sewing – the so-called “Sewing Advisor.” In simple machines in a special display shows the current settings of the machine – the selected line, its width and stitch length, thread tension, and the like. More complex can tell what settings are recommended for a particular tissue type, and what foot and the needle should be used to perform a particular sewing operations. Many machines to monitor the proper sewing process, for example, does not allow you to select the excessive width of the stitch during sewing with the twin needle, do not start sewing with raised foot and signaled the imminent end of the bobbin thread. The most sophisticated machines can detail, with pictures and even short videos to tell you how you need to perform a sewing operation, for example, an invisible hem skirt edge.
Threader This is a useful tool designed to facilitate threading the needle. This is especially true when it comes to frequently change the color of the thread, or if you do not see very well. In order to fill the thread a needle with the help of this device, simply skip the thread through the needle threader hook and release (or press – depending on the design) a small lever. The thread will push the needle eye and will only finally pull a loop.
The upper conveyor conveyor fabric – an essential mechanism for anyone, even the most ancient of the sewing machine. It provides a conveyor required stitch length by advancing the fabric between two punctures needle. When working on machines equipped with conventional fabric transporter can be problems when sewing thin materials, such as silk, chiffon, viscose, fine synthetic fabric – fabric layers can move relative to each other.
