Overlockers / sergers typically come with a presser foot pressure adjustment feature.
This allows you to control the amount of pressure applied by the presser foot on the fabric, as it feeds through the overlocker / serger.
Adjusting the pressure of the presser foot is important to accommodate different types of fabrics, from lightweight to heavy, ensuring smooth and even overlocking / serging.
Incorrect pressure of the presser foot can lead to various problems. If you are having any of the following problems then it's worth checking your presser foot pressure:
Uneven Stitching
Incorrect presser foot pressure can cause the fabric to feed unevenly through the machine. This may result in uneven stitches, with some areas having too much tension and others having too little. Your overlocked / serged seams may appear wavy or puckered as a result.
Fabric Stretching
Too much presser foot pressure can cause the fabric to be stretched as it moves through the machine. This is especially problematic when working with lightweight or delicate fabrics, as it can distort the fabric.
Fabric Gathering
Conversely, too little presser foot pressure may lead to fabric gathering or bunching. This is problematic when working with heavy fabrics or knits, as it can create uneven seams and make it challenging to achieve a smooth, professional finish.
Thread Breakage
Incorrect pressure can also contribute to thread breakage. If the presser foot is too tight on the fabric, it can put excessive tension on the threads, causing them to snap during overlocking / serging.
Feeding Problems
Inconsistent presser foot pressure can lead to feeding problems, where the fabric doesn't move smoothly through the machine. This can result in jams, skipped stitches, or the fabric not advancing properly.
In Summary
To avoid presser foot issues with your overlocker / serger, it's essential to adjust the presser foot pressure according to the type of fabric you're working with.
Lighter fabrics typically require less pressure, while heavier fabrics may need more pressure.
Consult your overlocker / serger manual for guidance on adjusting the presser foot pressure on your machine (yes, we give this advice a lot but all overlockers / sergers are different so you do have to check the manual for your specific machine).
After making adjustments, test on a scrap piece of fabric to ensure the settings are correct before starting your sewing project.
When using an overlocker / serger, proper presser foot pressure adjustment is crucial for achieving neat, professional-looking seams and finishes on your garments or projects.
