Best sewing machine shuttle timing adjustment

Best sewing machine shuttle timing adjustment. 

It is essential that your sewing machine will timely attach the same stitches to your fabric and to ensure that the machine parts will work in the sink.

Although most industrial sewing machines have the same general process of setting the time for timing adjustment, the method of removing, modifying, and installing parts is different for each machine, so consult your owner's manual. The machine undergoes adjustment while checking and repairing the equipment.

While a sewing machine has different timing, hook time is the most common for sewing machine malfunctions. The hook timing setting of an industrial sewing machine is the ratio of the hook point of the needle's eye.

If you feel that your sewing machine may have a timing problem, a careful examination of the hook and needle can confirm that condition.

When the needle goes up, it forms a loop between the needle's eye and the fabric, behind the needle. To make a stitch the point of the hook must pass through that loop.

The hook is a good timing adjustment, depending on the make and model of the industrial sewing machine timing adjustment, but almost all sewing machines follow this basic principle.

1. Check for other possible problems: First check for other factors that may cause timing problems; There is no point separating time adjustments from your industrial sewing machine if not necessary!

Ensure that the needle is not bent and that it has been fully inserted and screwed tightly.

Check that the needle, thread weight and fabric are compatible. Heavy needles require large needles and thick threads.

2. Check the timing problem by running a timing test: By testing the needle and shuttle hook alignment, you can determine whether your machine needs a time adjustment.

Leave the needle threaded, but remove the switch plate, base cover, and bobbin case.

To ensure that the hook on the wheel holds the thread, gently rotate the hand wheel. Otherwise, you may need to adjust the time.

Use a ruler to measure time settings: Use the hand wheel to set the needle to the lowest position, then lift it 3/32 inch up. In this case, the shuttle hook must meet the needle above the eye. Otherwise, you may need to adjust the time.

1. Adjust the height of the needle bar. Most machines have markings that indicate the appropriate height for the needle bar. Consult your manual for details on how to use and loosen needle bars.

If there are time marks, loosen the needle bar and slide it up or down and align the upper time mark under the timing bar bushing.

If there are no timestamps, lower the needle completely with the handwheel and then lift it 3/32 inch (2.4 mm) up. Adjust the height of the needle so that the eye of the needle is 3/32 inch below the point of the hook.

2. Set the time of the hook. Hook timing adjustment varies by manufacturer and model. However, the general approach is to adjust the distance between the hook and the needle.

Using the hand wheel, the industrial sewing machine moves the needle bar to its lowest position for time adjustment.

Wherever it depends on the machine, make adjustments between 0.04 mm and 0.1 mm [3] or 0.01–0.16 in addition to the hook and needle at the appropriate distance.

3. Check the accuracy of time. By removing the alignment of the needle and shuttle hook, you can determine whether the timing adjustment of your industrial sewing machine has improved machine settings.

If you remove the needle thread, raise it again. Continue working with the area of the exposed coil.

To ensure that the hook on the wheel holds the thread, gently rotate the hand wheel. If the hook catches the line every time, then your time is set.

Part 3.

Reassemble your machine. Carefully tighten all bolts and ensure that there are no "remaining" parts that have not been replaced.

• Clean and lubricate any exposed gears while their covers are still removed.
• Remove any lint or dirt from the gears and push the teeth forward.
• Consult your manual to find specific areas requiring lubrication.
• Use only specific sewing machine oil in your sewing machine.
• Replace cover and switch plate.
• Test your configuration. Re-thread your machine and sew a test piece of material.
