Industrial Sewing Machine Bobbin Case
Most modern models of sewing machines are equipped with special bobbin cases to increase the efficiency and productivity of working with fabric. At the moment, there are several main types of industrial sewing machine bobbin cases, which can differ significantly in their characteristics and functions.
Bobbin cases are laying the left thread between the warp threads when processing the material. Taking into account modern technologies, such elements perform oscillatory or rotational movements in a horizontal or vertical platitude. Based on these indicators, it is customary to distinguish between diverse types.
The Main Types of Bobbin Cases
There are three main types of industrial equipment that differ in bobbin case type. Firstly, modern types of sewing equipment need to be selected exactly according to the type of shuttle, since it is responsible for the technology of processing fabric, sets the rhythm and speed of work. Bobbin case price closely depends on the equipment type.
The sewing machine bobbin case main types are the following:
- Swaying vertical shuttle.

A vertical shuttle rotating in a circle also could be called a rotary or double-fitting shuttle is most often used in higher class machines. This vertical hook is used in many industrial sewing machine models. - Horizontal shuttle type.
Currently, It is the most common type of shuttle in many functional electromechanical and computerized sewing machines. The horizontal hook doesn’t have a special bobbin case, while the bobbin is inserted right into the hook, which is convenient and simple.
The Main Issues Using Various Types of Sewing Machine Bobbin Case
While using industrial sewing equipment, some problems can occur. Commonly, they are the following:

Removable vs. Drop-In Bobbin Cases:
- Removable Bobbin Case: Some sewing machines have removable bobbin cases that can be taken out for cleaning or adjustment. These cases are often found in older or more specialized sewing machines.
- Drop-In Bobbin Case: Many modern home sewing machines have a built-in, drop-in bobbin system. In this design, the bobbin case is typically located directly under a top-loading bobbin cover. Users simply drop the bobbin into the case, thread it through the guides, and close the cover.
Features of Bobbin Cases
- Tension Control: The bobbin case plays a significant role in controlling the tension of the lower thread. Proper tension adjustment ensures that the stitches are balanced and secure.
- Threading: When inserting a bobbin into a removable bobbin case, it's essential to follow the machine's threading instructions carefully. Proper threading ensures that the bobbin thread feeds correctly during sewing.
- Maintenance: Bobbin cases, especially removable ones, should be periodically removed, cleaned, and oiled as part of sewing machine maintenance. Lint and debris can accumulate in the bobbin case, affecting its performance.
- Compatibility: Bobbin cases are designed to be compatible with specific sewing machine models. Using the correct bobbin case for your machine is essential for proper tension and stitch quality.
- Tension Adjustments: Some bobbin cases have tension adjustment screws that allow you to fine-tune the tension of the lower thread. This can be useful when working with different fabrics or threads.
- Troubleshooting: If you encounter stitching issues, such as thread nesting or uneven tension, problems with the bobbin case or its threading may be a contributing factor. Consult your sewing machine's manual for guidance on troubleshooting bobbin-related issues.
