Definition and Types of Low Shank Sewing Machines
A low shank sewing machine is a type of sewing machine characterized by its design and functionality. It is primarily used for industrial and heavy-duty sewing applications, but has also gained popularity among serious home sewers and crafters who require precision and durability in their sewing machines.
Difference between Low Shank and High Shank Sewing Machines
Low shank sewing machines differ from high shank machines in their foot bed design and the type of presser feet they can use. Low shank machines have a more compact foot bed and are designed to use low shank presser feet, while high shank machines have a larger foot bed and use high shank presser feet. This difference affects the type of projects that can be sewn on each machine, with low shank machines better suited for heavy-duty and industrial sewing and high shank machines better suited for home sewing and craft projects.
Types of Low Shank Sewing Machines
Low shank sewing machines are available in a variety of types, each designed for specific applications and sewing needs. The main types of low shank sewing machines include:
- Industrial Straight Stitch Sewing Machines – These machines are designed for heavy-duty sewing and are commonly used in industrial settings for tasks such as garment construction, upholstery, and leatherworking. They are known for their durability and ability to handle thick fabrics and heavy stitching.
- Overlock (Sergers) Sewing Machines – These machines are designed for finishing seams and are commonly used in garment construction, upholstery, and other industrial settings. They are known for their ability to quickly and efficiently finish seams and prevent fraying.
- Zigzag (Hemming) Sewing Machines – These machines are designed for sewing straight and zigzag stitches and are commonly used in garment construction, home decor, and craft projects. They are known for their versatility and ability to sew a variety of stitches.
- Twin Needle Sewing Machines – These machines are designed for sewing twin needle stitches, often used in garments that require a precise stitch like pants, skirt, and jackets. They can create a precise stitch, making them ideal for garments with complex stitching needs, which require the precise alignment of two needles working in parallel.
Advantages and Disadvantages of Low Shank Sewing Machines
Low shank sewing machines offer several advantages, including their durability, versatility, and ability to handle thick fabrics and heavy stitching. They are also designed for heavy-duty sewing and are commonly used in industrial settings, making them ideal for tasks such as garment construction, upholstery, and leatherworking. However, they can also be more expensive and heavier than high shank machines, making them more difficult to move and store.
Components and Mechanism of Low Shank Sewing Machines
Low shank sewing machines, like any other mechanical device, consist of various components that work in harmony to produce the desired outcome. The components of a low shank sewing machine include the sewing head, the take-up lever, the feed dog system, the presser foot, the bobbin case, and the needle. Understanding the basic components is crucial to grasp the mechanical movement of the needle and the presser foot, which together enable the sewing process.
The mechanical movement of the needle and the presser foot is crucial to the functioning of a low shank sewing machine. The presser foot, located on the machine bed, holds the fabric in place and provides pressure on the fabric to maintain uniform tension. The presser foot bar enables the user to adjust the pressure as needed. The needle, a metal component attached to the machine’s arm, moves up and down within a small cylinder referred to as the machine casing.
Mechanism of Needle Movement
- As the machine is turned on, the power of the motor is transferred to the gear system through the gear teeth. This gear system is attached to the arm holding the needle, which begins to move up and down.
- The mechanism of the needle movement can be divided into the following stages: (1) the needle moves up, piercing the fabric and engaging with the hook on the underside of the machine. (2) As the needle moves upwards, a small gear on the arm rotates, which, in turn, activates the hook. The hook moves around, engaging with, and picking up the upper thread of the fabric.
- During the second stage in the down position, the gear rotates, allowing the hook to disengage from the upper thread, pick up the lower thread from the spool, and then move upward, allowing the needle to go down through the fabric once again, thus completing a sewing motion.
Components Involved in the Sewing Process
Several key components work together to achieve the sewing process in a low shank sewing machine. These components include the sewing head, take-up lever, presser foot, feed dog system, bobbin case, and needle. The following diagram illustrates these components and their relationships in further detail.
| Component | Description |
|---|---|
| Sewing Head | The part of the machine containing the needles, bobbin, and presser foot. |
| Take-up Lever | A component that helps in maintaining the desired tension of the fabric by pulling the fabric with a spring action. |
| Presser Foot | A component located on the machine bed that helps in holding the fabric in place and provides the necessary pressure on the fabric. |
| Feed Dog System | A component attached to the needle bar, that moves the fabric under the needle to help in the sewing process. |
| Bobbin Case | The container holding the spool of thread for the underside of the fabric. |
| Needle | A component attached to the machine’s arm that moves up and down within the machine’s casing to sew the fabric. |
