The search for reliable sewing equipment for the home often leads to models that combine time-tested technology with modern ergonomics. Such a device is Veritas Rubina - a sewing machine that has earned the respect of craftswomen for its unpretentiousness and ability to cope with dense fabrics. Unlike many plastic counterparts, this device is often equipped with metal internal mechanisms, which guarantees a long service life even with intensive use. Potential owners are looking for information on how to set up this tool so that it runs silently and without skipping a stitch.
In this article we will examine in detail the technical features shuttle stroke, which is the heart of this model. Many users encounter difficulties when threading or adjusting thread tension for the first time, without understanding the basic principles of the mechanism. Understanding exactly how the needle and shuttle interact in Veritas Rubina, will allow you to avoid most common mistakes. We'll look at the nuances of working with different types of fabrics and provide expert maintenance advice.
Particular attention should be paid to the fact that the model equipped with a horizontal or vertical swinging shuttle (depending on the specific modification of the year of manufacture), which requires a specific approach to lubrication. This is a critical point, since improper maintenance can lead to rapid wear of rubbing parts. Next, we will move on to a detailed analysis of the functionality and instructions that will help you master this technique in the shortest possible time.
Technical characteristics and design features
Construction Veritas Rubina is based on classical mechanical engineering principles adapted for domestic use. The main element that determines the quality of the stitch is the type of drive and the loop formation mechanism. Most modifications use swing shuttle, which provides high sewing speed and minimal vibration levels. The machine body is made of durable composite materials, which reduces the overall weight of the device while maintaining the necessary rigidity of the frame.
The most important parameters are the engine power and the maximum speed of needle puncture. For Veritas Rubina these indicators are optimized for working with medium and heavy fabrics. The system for adjusting the presser foot pressure on the fabric allows you to work not only with cotton, but also with denim or fine wool. Electronics, if present in a particular configuration, are responsible for the smooth operation and accuracy of needle positioning.
Internal structure of the mechanism
Inside the case there is a metal frame that protects the gears from distortions. Unlike their all-plastic counterparts, this one uses a hybrid approach: plastic gears often have a metal core for strength.
It is worth noting the work area lighting system. In modern versions LED backlight positioned in such a way as not to create shadows from the operator’s paw or hands. This significantly reduces eye fatigue during long-term work. Also important is the free sleeve, which makes it easy to handle cuffs and trouser legs.
- 🧵 Shuttle type: horizontal rotary or vertical swinging (depending on the year of manufacture).
- ⚡ Motor power: Provides stable puncture of up to 4 layers of denim.
- 🎚️ Adjustments: thread tension, stitch length and width, presser foot pressure.
- 💡 Lighting: built-in LED lamp with a directional beam of light.
The reverse mechanism is made reliably and does not require excessive effort to activate. This allows you to secure the beginning and end of the stitch without the risk of breaking the lever. All adjustment units are located on the front panel or upper part of the case for easy access.
Preparing for work: installing the needle and threading the thread
Correct needle placement is the foundation of quality stitching on any machine, and Veritas Rubina is no exception. The needles should be installed with the flat side of the flask in the direction indicated in the instructions (usually back or to the right, depending on the shuttle model). If the needle is not installed correctly, thread pick-up mechanism will not work, resulting in constant skipped stitches or broken threads.
The process of threading the upper thread requires care, since the thread path includes several important nodes. The thread first passes through the upper thread guide, then lowers to the tension regulator. It is important here that the thread gets between the disks. tension regulator, otherwise the line will loop. Next, the thread passes through the thread take-up, which moves up and down, ensuring that the thread slack is retrieved.
☑️ Correct refueling of the car
Threading the bobbin thread into the bobbin case also has its own nuances. The thread should come out of the bobbin counterclockwise (for a vertical shuttle) or in a certain pattern for a horizontal one. The tension of the lower thread is adjusted by a screw on the hook itself, but this adjustment should be resorted to only in extreme cases, preferring to adjust the upper thread.
⚠️ Attention: Never rotate the machine flywheel in the opposite direction (towards you) during operation, unless otherwise specified in the instructions. This may cause the thread to become tangled in the hook and the timing settings may be lost.
After threading, you need to pull the bobbin thread up. To do this, holding the end of the upper thread with your left hand, make one full turn of the handwheel with your right hand. The needle will drop, catch the bobbin thread, and pull it through in a loop. Now both threads are under the foot and you can start sewing.
Adjusting thread tension and stitch quality
The quality of the stitching directly depends on the balance of the tension of the upper and lower threads. In the car Veritas Rubina The dial located on the front panel is responsible for this. An ideal stitch is obtained when the thread connection knot is hidden inside the thickness of the fabric. If the knot is visible from above, it means that the lower thread is too tight or the upper thread is loose.
The adjustment is made experimentally on a scrap of the same fabric from which you plan to sew the product. By turning the regulator dial, change the force of the thread clamping by the discs. The numbers on the disk indicate conventional units of force: the larger the number, the stronger the tension. For thin fabrics, values of 2-3 are suitable, for dense fabrics - 4-5.
Always clean the hook area of lint and dust before adjusting tension. Even a small speck of dust can disrupt the smooth flow of the thread, creating the illusion of incorrect tension.
There is a concept dynamic tension, which depends on the sewing speed. When suddenly accelerating or decelerating, the machine may experience temporary defects. Therefore, it is important to develop the skill of smoothly pressing the pedal. Also, the quality of the stitch depends on the correspondence of the needle number to the thickness of the thread.
If you notice that the fabric is starting to wrinkle or tighten, check to see if the presser foot is applying too much pressure. Excessive pressure will distort the material and may cause the fabric to ripple when removed from the machine. For Veritas Rubina optimally adjust the pressure so that the fabric moves evenly, without effort on the part of the operator.
- 🔍 Top loop: loosen the tension on the top thread or increase the tension on the bottom thread.
- 🔍 Bottom loop: increase the tension of the upper thread or loosen the lower thread.
- 🔍 Thread breakage: check the quality of the thread, the presence of burrs on the needle or too much tension.
- 🔍 Skipped stitches: Replace the needle with a new one or check that it is installed correctly.
Working with different types of fabrics
Versatility Veritas Rubina allows you to process a wide range of materials, from chiffon to drape. However, each type of fabric requires the selection of appropriate equipment. For knits and elastic materials, it is necessary to use needles with a rounded tip (type Stretch or Jersey), which push the fibers apart rather than puncture them, preventing holes from forming.
When working with dense materials, such as jeans or coat wool, the puncture power and needle sharpness are important. Type needles are used here Jeans with reinforced rod. If the machine refuses to advance a thick seam, you can use the technique of placing an additional piece of paper under the presser foot, which can then be easily torn off.
| Fabric type | Recommended needle number | Stitch length(mm) | Settings Features |
|---|---|---|---|
| Silk, chiffon | 60-70 | 2.0 - 2.5 | Minimum presser foot pressure |
| Cotton, linen | 80-90 | 2.5 - 3.0 | Standard tension |
| Jeans, thick wool | 100-110 | 3.0 - 4.0 | Reinforced needle, maximum pressure |
| Knitwear, stretch | 75-90 (Stretch) | 2.5 - 3.0 | Using the knit foot |
Sewing leather or leatherette requires special attention. These materials require special spear-shaped needles that easily cut the material. The skin does not restore its structure after a puncture, so any errors in markings or extra holes from the ripper will be visible forever. In this case, you need to drive the car confidently, without stopping in place.
Typical faults and methods for their elimination
During operation, situations may arise when the machine begins to make noise, knock, or sew poorly. Most often, the problem lies in contamination of the shuttle compartment with lint and dust from the fabric. Regular cleaning with a soft brush and blowing with compressed air can eliminate 90% of stitch quality problems. Don't forget that timely lubrication rubbing parts also prolongs the life of the mechanism.
If the machine makes a loud knocking noise, check the fastening of the needle bar and the needle itself. A loose needle screw can cause the needle to hit the hook plate, which can cause the needle to break and damage the hook tip. If the thread (“beard”) gets stuck under the foot, do not pull the fabric by force. It is necessary to carefully cut the thread, lift the foot and pull out the ball, checking the passability of the threads.
⚠️ Warning: If you hear metal scraping on metal, stop working immediately. Continued sewing may cause permanent damage to the drive gears or shaft.
Problems with fabric advancement are often solved by replacing the feed rack or cleaning the teeth from clogged lint. Sometimes adjusting the height of the rack helps. If the fabric is slipping, check that the feed release lever (if your model has one) is not down and that the sole of the presser foot is worn.
Most sewing machine “breakdowns” are the result of using dull needles, low-quality threads, or lack of cleaning of the mechanism.
Car care and operating rules
In order to Veritas Rubina has served for many years, it is necessary to follow simple operating rules. After each sewing session, it is advisable to wipe the body with a soft cloth and remove dust from the working area. Once every few months, depending on the intensity of use, the shuttle passage should be completely cleaned and the components should be lubricated with special oil.
Use only sewing machine oil. The use of household oils (for example, for bicycles or cooking oils) is unacceptable, as they thicken over time, turning into a sticky substance that blocks the mechanism. A drop of oil should be applied only to metal rubbing parts, avoiding contact with plastic parts and rubber belts.
The machine should be stored in a cover or case to protect it from dust and moisture. Sudden temperature changes and high humidity can lead to corrosion of metal parts and the appearance of condensation inside electronic components. If the machine is not used for a long time, it is recommended to lower the presser foot to relieve the lift lever spring.
- 🛢️ Lubricate the machine only with special oil for sewing equipment.
- 🧹 Clean the shuttle compartment after each sewn product.
- 🪡 Change the needle after every large project or when defects appear.
- 🔌 Disconnect the machine from the network when it is idle for a long time or when replacing a light bulb.
Regular maintenance not only improves sewing quality, but also prevents serious damage. If you notice that the machine has become harder or noisier, this is the first signal about the need for preventive maintenance. Careful handling of technology will pay off with impeccable work when creating your products.
Frequently asked questions (FAQ)
Which needle is best to choose for sewing jeans on Veritas Rubina?
Marked needles are best suited for denim. Jeans or Denim numbers 100 or 110. They have a reinforced shaft and a sharp tip, which allows you to confidently pierce dense weaves of threads without the risk of needle breakage or skipped stitches.
Why does my machine skip stitches on knitwear?
Skips in knitwear are most often caused by using a regular needle with a sharp tip, which tears the fibers, or by improper needle placement. Solution: Replace the needle with a special knitting needle (with a rounded point) type Stretch and make sure it is inserted all the way.
How often should you lubricate your sewing machine?
The frequency of lubrication depends on the intensity of work. For home use, it is enough to lubricate the main components 1-2 times a year. If you sew daily and a lot, then you should lubricate the machine once every 1-2 months, after first cleaning the mechanism from old oil and dust.
Is it possible to sew on Veritas Rubin without a foot?
Sewing without a foot is possible only in exceptional cases and requires high skill, since the foot provides the necessary clamping force for the operation of the fabric advancing mechanism. Without a foot, the fabric will move unevenly and the stitching will be of poor quality. For standard operations, always use the presser foot.
