Video review Janome MC 6700P:

So, the story has been read and now we are moving on to an overview of the features that, in my opinion, a sewing machine should have.

1. Long platform.

If you have sewn a patchwork quilt at least once, then you probably shouldn’t talk about how much torment and inconvenience you have to experience when stitching on a machine, even if you fold it into a tube, fasten it with special clips, etc. Therefore, the larger the platform of the sewing machine (the distance between the needle and the side of the body), the easier it will be for you to quilt large and bulky items.

To date, there are only a few types of household sewing machines (sold in Russia) that have such characteristics - this is the Husqvarna Sapphire series model 830, 850, 870, Janome Memory Craft model 6500P and 6600, New Home NH 8460.

Sewing machine Husqvarna Sapphire 850 Sewing machine Janome Memory Craft 6500 P Sewing machine Janome Memory Craft 6600 Sewing machine New Home NH 8460

Let's compare this characteristic for several types of machines.

2. Top conveyor.

What is the top conveyor and what is it for? Surely, when stitching a patchwork quilt on a sewing machine, they encountered the fact that excess fabric sometimes appears on the patchwork fabric and, as a result, creases. This is due to the different speeds at which the top and bottom layers of your blanket advance. The bottom layer of fabric helps you to advance the lower feed located under the needle plate, and the top layer advances by inertia, but at a slower speed. In order to avoid creases, a uniform supply of all layers of fabric is necessary. The top conveyor will help you with this.

Top conveyor- This is a device that helps to evenly advance the upper layers of the fabric. There are two types of conveyors: active (built-in) and passive (removable).

Pfaff Integrated Top Conveyor (IDT) Janome top conveyor Husqvarna top conveyor

Pfaff sewing machines (the so-called IDT Integrated Dual Transporter system) and the Janome Memory Craft 6600 sewing machine have a built-in upper conveyor. It is good because it allows you to work with any foot, while it is removable only with a universal foot, which is often not comfortable. For other sewing machines, the conveyor is usually removable and is installed instead of the usual presser foot for sewing.

3. An additional table that increases the working surface of the machine.

As I wrote above, the larger the working surface of the sewing machine, the better for the quilter. To this end, some manufacturers increase the size of the work surface due to side tables. They are transparent (made of plexiglass) and non-transparent.

Additional table for Husqvarna sewing machine Additional table for Brother Innov-is NV-600

An additional work table (included in the kit) is available for the following models of machines:

New Home NH 8460;
Janome Memory Craft 6500 P;
Janome Memory Craft 6600;
Jaguar 979;
Jaguar 312;
Brother Innov-is NV-400;
Brother Innov-is NV-600;
Bernina Aurora 435;
Brother M 955Q (ACE II).

For some car models (Pfaff, Husqvarna), it is sold separately.

4. Automatic stitch length regulator.

When I started writing this article and began to study various models of sewing machines, I came across a very interesting solution offered by Bernina. This is the BSR (Bernina Stitch Regulator) foot, which allows you to maintain a uniform stitch length during free-motion or winding dotted line (or zigzag) stitching. This foot, with three different soles, guarantees a constant stitch length for varying fabric speeds under the foot and signals if you are moving the fabric too fast. In my opinion, this is a truly unique proposition, since it has always been read that there are only two ways in which the free-motion stitch length can be adjusted: the sewing speed and the feed speed. This foot is included with the following Bernina sewing and embroidery models:

Aurora 440QE;
Aurora 430;
Artista 640;
Artista 730.

5. The regulator (limiter) of the maximum sewing speed.

Adjusting the sewing speed of the sewing machine will allow you to choose the speed mode that is most comfortable for you. Moreover, the speed will remain constant, regardless of how hard you press the pedal. This is especially useful when quilting, embroidering decorative stitches or sewing "critical" areas.

6. Adjusting the pressure of the foot on the fabric.

The presence of adjusting the presser foot pressure on the fabric in the sewing machine is also essential, because it improves or worsens the movement of the foot on the fabric. This is especially true when working with multilayer products. For example, when processing silk, the fabric can slow down under the foot and stretch. To eliminate this defect, you need to loosen the pressure of the foot on the fabric. And if you are sewing a thick fabric or a patchwork quilt, then the presser foot pressure is increased. Many sewing machines have a presser foot pressure regulator that allows you to adjust the presser pressure for the best result.

7. Adjusting the length and width of the stitch.

All machines have this capability, and I won't go into detail on this feature. I can only say that the Pfaff Performance 2056 has the maximum stitch width among household machines - 9mm.

The best examples of sewing machines have a stitch length of up to 6 mm, and most inexpensive machines - 4 mm.

8. Programmed stop of a needle in the top or bottom position.

When working on a machine equipped with a needle position programming function, you do not need to turn the handwheel once again by hand - the needle will always stop in the position you need. This function is very convenient when quilting.

9. Needle threader.

The following models have a needle threader:

Pfaff Performance 2056;
Pfaff Quilt Expression 2048;
Pfaff Expression 2038;
Pfaff Expression 2028;
Janome Memory Craft 6500 P;
Janome Memory Craft 6600;
Husqvarna Sapphire 830;
Husqvarna Sapphire 850;
Husqvarna Sapphire 870;
Husqvarna Platinum 735;
Brother Innov-is NV-200;
Brother Innov-is NV-400;
Brother Innov-is NV-600.

And this is not a complete list!!

10. Thread cutter.

This is a convenient but not required feature. It allows you to press the corresponding key on the machine after finishing sewing, in which case the upper and lower threads will be cut automatically.

Thread cutters are available for the following models:

Husqvarna Sapphire 870;
Janome Memory Craft 6500 P;
Janome Memory Craft 6600;
Brother NX-400;
New Home NH 8460;
Janome 4900 QC.

11. Knee lever for lifting the presser foot.

On some models of sewing machines, it is possible to use the knee lever to control the presser foot lift - just like on professional industrial machines. At the same time, your hands remain free when operating the machine!

The knee lever for lifting the presser foot, which is included in the package, is available for the following models:

Brother NX-400;
Brother NX-600;
Janome Memory Craft 6600;
Janome Memory Craft 6500 P;
Brother Innov-is NV-600;
Bernina Aurora 440 QE;
Bernina Artista 730;
Janome 4900 QC.

If the sewing machine you like does not have a knee lifter, ask if it can be purchased separately.

12. Disabling the lower conveyor.

The bottom feed refers to the teeth of the sewing machine located under the needle plate, which help to feed the fabric. If they are turned off, you get the opportunity to quilt your quilt using the free-motion technique. However, for this, it is necessary to use a special foot (see below).

So, we have considered the main possibilities. What else might you need? Well, of course, paws!

In addition to the standard feet that come with your sewing machine, you may need:

1. Quilting foot.

The quilting foot will allow you to sew seams with a 1/4 inch (6mm) allowance. The red 1/4" (6mm) and 1/8" (3mm) marks on the front and back of the needle are for turning the fabric.

Husqvarna quilting foot Pfaff quilting foot

By no means do I insist on buying it, but my advice is, if possible, get it. For stitching parts, I only use it and I know for sure that the seam width is 6 mm (1/4 inch). Such accuracy is important for me to calculate the details of the block.

2. Transparent foot (foot for applications).

This foot is designed for appliqué, decorative and satin stitches. It is made of transparent plastic and allows you to optimally observe the working area while sewing.

You don't have to buy it specifically. The standard foot supplied with the sewing machine can be used for making appliqués. The main thing is that she had a large hole. Only in this case you will be able to see as much as possible the area to which you attach the application.

3. Open quilting foot.

This metal open presser foot allows you to easily feed and move the fabric by hand with the free motion technique. It happens closed and open.

Husqvarna open quilting foot Pfaff quilting foot

4. Quilting guide.

The quilting guide will help you to sew in parallel lines without prior marking.

Of course, this is not the whole set of feet that you can buy for your sewing machine. You need to make your own choice.

And finally, let's talk about ... lines. Today, almost every machine has both working stitches (straight stitch, zigzag, elastic zigzag for sewing on elastic, invisible hem stitch, elastic stitch, etc.) and decorative stitches.

The higher the class of the machine, the more lines it can do. It can be various ornaments, scalloped hems, stitches made with satin stitching, elements of the simplest embroidery - cross stitches, hemstitches, openwork stitches and so on. Complex models have one or even several alphabets stored in memory. Some models have in their arsenal not only Latin, but also Russian alphabets.

I think that the presence of a large number of decorative stitches will be especially interesting for those who are fond of the Qrazy technique. Some sewing machine manufacturers include quilting stitches in their menu right away.

So, if you have not yet decided on the choice of a sewing machine, I really hope that my article will help you with this. But I, for my part, in no way set you up to choose one or another machine. You decide!

Happy sewing!

The quilting guide will help you to sew in parallel lines without prior marking.

Of course, this is not the whole set of feet that you can buy for your sewing machine. You need to make your own choice.

The rail works with a presser foot, which must press the fabric against the rail over its entire area with a certain force. The presser foot assembly has an adjustable spring for this, as well as parts that lift the foot and lower it onto the fabric.

The presser foot can be with a movable sole and with a swivel sole. Such paws are convenient in that they allow you to easily pass through thickened places. The foot assembly has the following device.

a - paw knot,
b - kinematic diagram of the foot assembly:

presser foot.

The presser foot 8 is attached with a screw to the rod 7. A spiral spring 2 is put on over the spring-holder 4, on which the adjusting screw presses from above. Under the action of the spring, the presser foot presses the fabric, the clamping force can be changed by adjusting the screw. If the screw is turned to the right, the spring, compressing, creates more presser foot pressure on the fabric, and vice versa.

To raise the foot in the head of the machine, a lever 5, equipped with a cam, is attached to the hinge screw. If you turn the lever and bring its cam under the side process of the clutch 3, the clutch will rise and raise the bar of the foot and the foot.

The rotational movement of the main shaft is converted into the oscillating movement of the shuttle by means of the shuttle mechanism.

a - shuttle node,
b - kinematic diagram of the shuttle mechanism:

crank,
connecting rod,
swing roller,
fork,
crawler,
shuttle shaft,
clip with a shuttle.

The movement of the main shaft through the connecting rod 2 is converted into an oscillatory motion of the oscillating roller 3. The slider 5, inserted into the fork 4 of the oscillating roller, is transmitted oscillatory motion from the roller. The slider moves in the fork and drives the shuttle shaft 6. At the left end of the shuttle shaft there is a holder where the shuttle 7 is inserted. When the oscillatory motion is transmitted from the rocking roller to the shuttle shaft, the angle of rotation of the shaft increases.

The thread take-up mechanism feeds the thread and tightens the stitch. The roller 3 of the thread take-up lever slides in the groove 4 of the cylindrical cam 5.

a - mechanism assembly,
6 - kinematic diagram of the thread take-up mechanism:

The lever 2 is reinforced with a pivot screw 7 in the hole 1 of the machine sleeve, and its arm, which has an eyelet 6 for passing the thread, protrudes from the slot of the front board.

When the cam rotates, the roller slides along the groove and drives the thread take-up lever, which moves up and down at variable speed and participates in the stitch formation process - slowly feeds the thread and moves down, quickly rises up and tightens the stitch.

Questions

Name the working bodies, what is their purpose?
What mechanisms of the sewing machine are used to convert rotary motion into reciprocating?
