Rotary Hook for Industrial Lockstitch Sewing Machine

In an industrial lockstitch sewing machine, the rotary hook is a crucial component of the machine’s mechanics, contributing to the stitching process. The hook’s primary function is to engage with the needle, creating the stitch by looping the upper thread with the lower thread (from the bobbin).

What Does the Rotary Hook Do?

The lockstitch sewing machine, designed for light-duty materials , curtaining and some slightly thicker materials such as upholstery fabrics, has a straight stitch mechanism that moves the material through the machine evenly. The hook plays a pivotal role in this process by coordinating with the needle to form the stitches. It catches the thread from the needle and intertwines it with the thread from the bobbin, creating a secure lockstitch.

Maintenance

Maintenance and occasional oiling of the hook are important for smooth operation and to prevent thread jams or skipped stitches. Regular cleaning and inspection of the hook area can help ensure optimal performance and longevity of the sewing machine.

How to Install the Rotary Hook on your Lockstitch Sewing Machine

When following any guidelines please make sure to keep your operating manual on hand for reference. Each make and model of sewing machines differ.

Tools you May Need

• New hook (if replacing)
• Screwdriver
• Lint-free cloth
• Sewing machine oil (if recommended by the machine’s manual)

Steps:

1. Safety First: Ensure the machine is switched off and unplugged to avoid any accidents during the installation process.
2. Accessing the Hook: Locate the housing area where the hook is placed. In most industrial sewing machines, this involves removing the needle plate and possibly other covers to access the hook mechanism.
3. Removing the Old Rotary Hook (if replacing):
   • Loosen and remove any screws holding the hook assembly in place.
   • Gently pull out the old hook from its housing.
   • Clean the area using a lint-free cloth to remove any lint or debris.
4. Installing the New Hook:
   • Carefully insert the new hook into its designated place in the housing, making sure it’s properly aligned.
   • Secure it in place by tightening the screws.
5. Adjustments (if necessary): Depending on the machine, you might need to adjust the timing or other settings to ensure the new hook aligns correctly with the needle for smooth operation. Refer to the machine’s manual for specific instructions or speak to your local sewing machine repairer.
6. Maintenance and Lubrication: After the installation, it’s a good practice to lubricate the hook area as recommended by the sewing machine’s manual. This helps ensure smooth movement and prevents premature wear and tear. Ensure you are using the right sewing machine oil for this.
7. Final Checks:
   • Reassemble any covers or parts removed to access the hook.
   • Plug in the machine and perform a test run without any fabric to ensure the hook moves smoothly and doesn’t catch on anything.

Please note that the steps mentioned are general guidelines. It’s crucial to consult the specific user manual of your industrial sewing machine for accurate instructions on hook installation, as different machines might have varying mechanisms and requirements.
