Mechanical Sewing Machine: Basic parts and accessories

(Source)

1. Hand Wheel

The handwheel is a knob, employed to manually raise and lower the needle, which is crucial for maneuvering through tight spaces and corners when sewing. Remember to always turn the wheel in your direction to prevent thread from becoming caught or tangled.

2. Foot Pedal

These markings serve as a roadmap for threading. This vital component of your machine directs the thread from the spool pin either around to the bobbin winder or, on certain machines, downward to the lower needle. Threading your thread through the thread guide helps regulate the tension of the thread. Remember the position of the thread guide may vary among different machine brands, so consult your manual for specific threading instructions tailored to your machine.

4. Throat Plate

The throat plate, sometimes referred to as the needle plate, is a metallic plate situated beneath the needle and presser foot. It features a small aperture through which the bobbin thread emerges, allowing the needle to pass through and create stitches. This plate is removable for cleaning purposes underneath.

5. Tension Dial

The tension dial regulates the speed at which the thread advances through the machine, influencing stitch tension. This is essential in sewing because the required thread tension varies depending on the materials used—such as the thickness of the fabric (for example, denim, leather, or upholstery fabric will require a different tension setting than cotton or silk). Every manual sewing machine is equipped with a knob or dial that enables adjustment of the tightness or looseness of stitch tension.

6. Feed Dogs

Feed dogs are small metal or rubber teeth that function to pull the fabric between the presser foot and throat plate. These components grip the fabric and facilitate its movement through the machine, ensuring even stitching. Additionally, the feed dogs play a role in regulating stitch length by controlling the amount of fabric fed through at any given time. It’s important to note that while guiding the fabric, you should allow the feed dogs instead of your hands to handle the movement of the fabric.

7. Removable Free Arm

The removable free arm is a detachable component that allows for easier sewing of cylindrical items like sleeves and cuffs by providing a narrower workspace. This section also doubles as storage for your sewing essentials.

8. Shank

The shank holds the different feet in place while you sew. The design of a sewing machine determines whether the shank is positioned high, low, or at an angle, and it’s compatible with snap-on, screw-on, or clip-on presser feet.

9. Needle and Needle Clamp

The sewing machine needle moves back and forth through the fabric without penetrating all the way like in hand sewing. Typically, machines come with a pre-installed needle, but your manual will explain how to change it. Regularly swapping needles ensures neat stitches.
As the name implies, the needle clamp secures the needle in position.

10. Spool Pin

The spool pin is where you place your thread to keep it steady while sewing. It can be horizontal or vertical, with horizontal ones offering smoother thread feeding.

11. Bobbin Winder

(Source)

The bobbin winder winds thread from the spool onto the bobbin, ensuring it’s wound tightly. Typically, an empty bobbin is placed on the bobbin winder to be filled from the spool. For even winding, it’s essential to start with an empty bobbin.

12. Tension Regulator

This dial regulates the tension of the top thread. Correct tension ensures that the top and bobbin threads intertwine to create even stitches. If the tension is too tight, stitches may pucker or break; if it’s too loose, the stitches won’t hold. For machines with a manual dial (like a mechanical machine) turning it counterclockwise reduces tension and clockwise increases it. For machines with digital controls (like a computerized machine) press higher settings to increase tension and lower settings to decrease it.

13. Take-Up Lever

(Source)

The top thread goes through the take-up lever, which moves up and down with the needle. Before positioning your fabric under the presser foot, raise the take-up lever completely, ensuring the needle is at its highest point. This prevents the needle from snagging the fabric.

Computerized Sewing Machine: Basic parts and accessories

Let me also introduce you to some common advanced parts of more advanced machines like a computerized sewing machine:

1. Start/Stop Button

The Start/Stop button allows sewing without using the foot pedal. It’s useful for beginners, longer sewing sessions, and precise stitching, offering more control and reducing foot fatigue.

2. LCD Screen

An LCD screen displays stitching options, patterns, and settings, providing user-friendly control and customization for various sewing tasks and techniques.

3. Touch Buttons

Touch buttons are very convenient that quickly pick the most common stitches like buttonhole and zigzag stitches. Press these to change your stitch type, and make your stitches bigger or smaller.

4. Automatic Needle Threader

An automatic needle threader helps to effortlessly thread the needle, saving time and reducing frustration for users, especially those with dexterity issues.

5. Thread Cutter

The thread cutter trims excess thread after sewing. It streamlines the sewing process, saving time and effort. It’s handy for quick adjustments between stitches and helps maintain neat, professional-looking seams.

6. Speed Controller

The speed controller keeps the sewing machine running at a consistent speed regardless of the pressure applied to the foot pedal.

7. Stitch Selector

Older sewing machines feature a dial for selecting different stitches, while newer ones have buttons for this purpose. Despite the varying methods for changing stitch types, the fundamental principle remains consistent. For most sewing tasks, the essential stitches to use are the straight stitch and zigzag. As you gain more expertise, you can experiment with the decorative stitches available on your machine.

8. Stitch Length Selector

The stitch length selector that comes in a dial or knob grants you the power to tailor the stitch length, whether you’re stitching in a straight line, zigzagging, or exploring intricate patterns. Stitch measurements vary between machines, often denoted per inch, spanning from 0 to 20 or metrically, from 0 to 4 stitches per millimeter, or simply by numerical values from 0 to 9. Opting for longer stitch lengths proves beneficial for temporary tacking lines, whereas for everyday sewing tasks, targeting a length of about 2 or 2.5 ensures ample strength for typical seams.

9. Stitch Width Selector

The dial or lever dedicated to stitch width governs the width of decorative stitches, like the zigzag stitch.

10. Menu Screen

Many computerized machines feature a menu screen, offering the convenience of adjusting functions and stitches. This setup often replaces individual selector dials for stitch type, width, and length.

11. Reverse Stitch Button

Pressing the reverse stitch button changes the direction of the stitches, enabling you to reinforce the thread at both the start and end of a seam.

12. Buttonhole Sensor

The buttonhole sensor determines the required size of your buttonhole by analyzing the button you’ve selected.

13. Quick Set Bobbin

The quick set bobbin feature simplifies bobbin threading and replacement. It saves time during setup and minimizes disruptions while sewing, ensuring smoother workflow and efficient stitching.
