Incorrect position of the flat needle tail relative to the needle driver is the most common cause of stitches and thread breaks in cars Janome. When the user tries to replace the consumable material, ignoring the orientation of the groove, the mechanism of forming the loop is broken, and the shuttle cannot grab the thread at the right time. That is why replacing the needle in the sewing machine requires not just mechanical insertion of metal into the holder, but strict compliance with the angles of rotation and landing depth prescribed in the manufacturer's technical manuals.
Ignoring these nuances leads to the fact that even a new, high-quality needle will work incorrectly, creating loops on the underside of the fabric or emitting a characteristic knock. In models Janome The fixation system may vary slightly depending on the series, whether it is mechanical models or computerized devices with automatic refueling. Understanding the physics of the process and following the installation algorithm accurately eliminates 90% of the problems with the quality of the seam associated with the needle.
Next, we will discuss the installation process in detail, paying attention to tool preparation, choosing the right type of needle and critical fixation points. The right installation is a guarantee that your sewing-machine It will last a long time and will please you with a smooth, beautiful line on any type of fabric.
Workplace preparation and needle selection
Before proceeding with the immediate replacement, it is necessary to provide sufficient lighting and free up the work area around the needle plate. Light should fall directly on the installation site, as the slightest shadow can hide an important landmark - a flat cut of the tail. You will need only the needle itself and perhaps a small screwdriver to work, although in most modern models. Janome a screw with a screwdriver head or a special key that comes with a set is used.
It is critical to find the right type of needle for your task. Universal needles are suitable for most fabrics, but knitwear requires needles with a rounded point (Stretch or Jersey), and for jeans - reinforced options (Jeans or Denim). The use of a dull or deformed needle is unacceptable, as it can damage not only the fabric, but also the very same. needleholder Or a shuttle mechanism.
- π§΅ Choose the right system needle (usually 130/705H for Janome home machines).
- π‘ Provide bright side or top lighting of the work area.
- π§ Prepare a screwdriver or key if the screw is tight.
- π§Ή Wipe the area of the needle driver from dust and pile before installation.
Pay special attention to the visual inspection of the new needle. Even a factory defect or microscopic defect in transportation can make the consumable unusable. Swipe your finger around the edge (carefully) or examine it carefully when zooming in: it should be perfectly smooth, without serrated. Never use a curved needle.At high speeds, it can break inside the mechanism, which will require expensive repairs.
Dismantling the old needle and cleaning the knot
The replacement process always starts with the removal of old consumables. To do this, you need to lower the needle to the extreme lower position, turning the flywheel on yourself. This action will provide access to the screw of the attachment and will safely remove the needle without hurting the sharp point. In some models Janome With electronic control, the position of the needle can be set with a button on the panel, but the mechanical rotation of the flywheel remains the most reliable way.
β οΈ Warning: Before any needle manipulation, be sure to turn the sewing machine off the socket or move the switch to the "0" position to avoid accidental engine start-up.
Using a screwdriver or key, loosen the screw holding the needle. Do not twist it completely, unless there is an urgent need, it is enough to make 2-3 turns so that the needle freely comes out. After removing the old needle, it is recommended to carry out preventive cleaning. In the area of the needle driver often accumulates compacted pile and dust, which can interfere with the dense planting of new metal.
To clean, use a small brush included in the kit, or a dry toothbrush. Blow the mechanism with compressed air or simply brush the contamination neatly. Cleanliness in the node of the needle is the key to a stable passage of the thread through the ear. If you notice oily spots or rust, gently wipe the surface with a dry lilaless wipe.
Algorithm of installing a needle in the holder
The most important thing is to install a new needle in the needleholder. In cars. JanomeAs with most modern household models, a standard fastening system is used. The tail of the needle has two sides: one round and one flat (cut). It is the orientation of this flat cut that determines the correctness of the entire mechanism.
Insert the needle into the hole of the needle holder up to the point. The movement must be confident, but without undue effort. The needle must enter the canal tightly. Now the most important step: turn the needle so that the flat cut of the tailing looks strictly to the right (if you look at the car from the front). Some older or specific models may have different orientations, so always check the instructions, but for 95% of models, the guidance is not the same. Janome The βflat side to the rightβ rule is an axiom.
βοΈ Control of needle installation
After the correct orientation, tightly twist the screw of the attachment. The force should be sufficient so that the needle does not turn and fall during the work, but excessive force should not be used so as not to break the thread. Check the reliability of the fixation by slightly pulling the needle down - it should sit dead.
Altitude adjustment and landing check
After installation, you need to make sure that the needle is at the correct height. If the needle is not inserted to the end, the time of lifting and lowering the needle driver will be lost, and the shuttle will not be able to pick up the thread loop in time. This will result in permanent stitches that cannot be corrected by adjusting the tension of the thread.
Visually check the position of the needle relative to the needle plate. When lowered to the lower position, the tip should pass exactly along the center of the hole in the plate, without touching its edges. If the needle touches the edge of the hole, it is a signal that it is either inserted curved or the wrong type is used (for example, a needle too thick for the selected plate).
| tissue | Recommended needle number | Point type | Features of installation |
|---|---|---|---|
| Thin silk, chiffon | 60-70 | Sharp (Sharp) | It requires a careful insert, easily breaks. |
| Cotton, linen, synthetics. | 80-90 | Universal. | Standard installation, flat cut to the right |
| Jeans, tight drape. | 100-110 | Enhanced (Jeans) | Insert to the point, control the passage through the thickness |
| Knitting, elastan | 75-90 | (Ball point) (Ball point) | It is important not to damage the fibers of the tissue. |
It is also worth checking the gap between the needle and the clamping leg. When lowering the needle, it should freely pass through the hole in the leg, without touching its edges. If you hear a light metal knock as you scroll the flywheel, stop immediately and check the centering.
Common mistakes when replacing a needle
Even experienced users sometimes make mistakes that negate all efforts to set up the machine. One of the most common problems is not raising the needle up enough before the screw is clamped. The needle should rest against the upper wall of the needle holder channel. If there is even a minimum gap of 1-2 mm, this will lead to a change in the interaction time of the needle and the shuttle.
Why does the needle break immediately after installation?
The common reason lies not in the needle itself, but in the wrong sequence of actions. If the user first lowers the foot and then tries to insert or replace the needle, or pulls the fabric with a raised needle, the metal bending occurs. Microscopic deformation is invisible to the eye, but the next puncture tissue "moves", and the needle enters the needle plate, instantly breaking.
Another common mistake is the wrong orientation of the groove. On one side of the needle is a long groove, which when sewing should be facing the thread (usually on the left, when viewed from the front, but depends on the model of the tanker). If you confuse the sides, the thread will fall into a short groove, not protected by metal, which will lead to its breakage or ragging.
- π« Ignore needle replacement after each new project.
- π« Using rusty or bent needles "for another time."
- π« Weak screw clamp, turning the needle.
- π« Installation of the needle of the wrong system (for example, with an ear-carving for old cars).
Remember that the needle is a consumable. Its resource averages 8-10 hours of clean sewing. If you sew denim or fabrics with a coating (teflon, leather), you need to change the needle even more often, since the abrasive effect quickly dulls the tip.
Diagnosing problems after replacement
After you have completed all the actions and filled the thread, you need to conduct a test run. Take a piece of fabric similar to the one you plan to work with and make a few lines. Pay attention to the sound: the working machine emits a smooth, monotonous hum. Any knocking, clanging or change in tone of sound indicates a problem.
If the machine has started to miss stitches, check the orientation of the flat cut again. Sometimes the screw may be twisted unevenly and the needle is skewed. In this case, loosen the screw, move the needle from side to side so that it stands in its place, and tighten again. Also check the tension of the upper thread β after replacing the needle, it often has to be adjusted.
β οΈ Note: If you feel a sharp resistance or locking mechanism when scrolling the flywheel, do not apply force. Stop spinning immediately, lift the needle and check if it is against something.
A high-quality line from the front and back is the main indicator of correct installation. Loops, puffs, breaks of thread or deformation of tissue indicate that there is a failure in the system. Most often, the problem is solved by repeating the installation procedure with greater care.
Tip: When sewing thick fabrics or multilayered structures (jeans, coat fabrics), change the needle to a thicker one (No. 100-110) and use a special foot for thick fabrics to avoid skewing the needle.
Frequently Asked Questions (FAQ)
How do you know if itβs time to change the needle if itβs not broken?
The main signs of dulling of the needle: the appearance of clicks when punctured tissue, tightening the thread into the fabric (loop from below), skipping stitches, the appearance of holes or "leads" on the fabric. If after replacing the needle the quality of the seam improved, then the old one was worn out.
Can I use needles from other brands in Janome?
Yes, you can. Machines. Janome They work with standard household needles of the 130/705 H system. You can safely use the needles of the brands Schmetz, Organ, Groz-Beckert, the main thing is to monitor the compliance of the number and type of the tip of your fabric.
What to do if the needle attachment screw is twisted too much?
Do not try to spin it by force, so as not to break the slime. Try to warm up the screw area slightly (carefully, with a hairdryer) or use a drop of penetrating lubricant (WD-40), with pause. If the screw has notches under a special key, use it, not a screwdriver.
Why does the needle constantly shift to the side while sewing?
This happens if the screw of the attachment is not tightened enough or the thread in the needle holder is worn out. Also, the cause may be a needle collision with a button or pin during operation, which leads to deformation of the holder. In the latter case, repairs are required in the service.
The correct installation of the needle in Janome depends on three factors: the needle must be inserted to the point up, the flat cut of the tail should look to the right, and the screw should be tightened reliably. Compliance with these rules guarantees the perfect quality of the seam.
