Hemming is a fundamental sewing technique used to finish the raw edges of fabric and create a clean, professional look. Industrial sewing machines are powerful tools designed to handle heavy-duty fabrics and high-volume production, making them ideal for hemming tasks in various industries such as garment manufacturing, upholstery, and automotive. As an industrial sewing machine supplier, I understand the importance of providing accurate information and guidance on how to use these machines effectively. In this blog post, I'll share some tips and techniques on how to use an industrial sewing machine for hemming.
Preparing Your Industrial Sewing Machine
Before you start hemming, it's crucial to ensure that your industrial sewing machine is properly set up and adjusted. Here are the key steps to follow:
- Select the Right Machine: Different types of industrial sewing machines are suitable for different hemming tasks. For example, a Computerized Post Bed Sewing Machine is excellent for hemming circular or tubular fabrics, while a straight stitch industrial sewing machine is great for simple, straight hems. Consider the type of fabric and the hemming job you'll be doing to choose the right machine.
- Needle and Thread Selection: Choose the appropriate needle and thread for your fabric. For heavier fabrics, use a larger needle and thicker thread, such as Tex 40 or Tex 60. For lighter fabrics, a smaller needle and finer thread, like Tex 20 or Tex 30, will work better. Ensure that the needle is properly inserted and tightened in the machine.
- Tension Adjustment: Correct tension is vital for a neat and even hem. Test the tension on a scrap piece of fabric by sewing a few stitches. If the thread is too loose, the stitches will look loopy; if it's too tight, the fabric may pucker. Adjust the tension dial on your machine until you achieve the right balance.
- Presser Foot Pressure: Adjust the presser foot pressure according to the thickness of the fabric. For thicker fabrics, increase the pressure to ensure that the fabric moves smoothly through the machine. For thinner fabrics, reduce the pressure to prevent stretching or distortion.
- Stitch Length and Width: Set the appropriate stitch length and width for your hemming task. A shorter stitch length is generally better for hemming as it provides more strength and a neater appearance. The stitch width can vary depending on the type of hem you're creating.
Types of Hems and How to Sew Them
There are several types of hems commonly used in sewing, each with its own unique appearance and application. Here are some of the most popular types and how to sew them using an industrial sewing machine:
Straight Hem
A straight hem is the most basic type of hem and is used to finish the edges of straight fabric pieces.
- Fold the Fabric: Fold the raw edge of the fabric under by the desired hem width, usually 1/4 inch to 1 inch. Press the fold with an iron to make it sharp and even.
- Sew the Hem: Place the fabric under the presser foot of your industrial sewing machine, with the folded edge aligned with the edge of the presser foot. Lower the presser foot and start sewing along the fold, using a straight stitch. Keep the fabric moving smoothly and evenly through the machine.
- Trim the Excess Fabric: After sewing the hem, trim any excess fabric close to the stitches using a pair of sharp scissors.
Double Fold Hem
A double fold hem is a more decorative and durable hem, often used for garments and home decor items.
- First Fold: Fold the raw edge of the fabric under by a small amount, usually 1/8 inch to 1/4 inch. Press the fold with an iron.
- Second Fold: Fold the fabric under again by the desired hem width, usually 1/2 inch to 1 inch. Press the second fold to make it sharp and even.
- Sew the Hem: Place the fabric under the presser foot of your machine, with the double folded edge aligned with the edge of the presser foot. Sew along the fold using a straight stitch or a decorative stitch of your choice.
- Trim the Excess: Trim any excess fabric close to the stitches.
Rolled Hem
A rolled hem is a narrow, delicate hem that gives a professional and elegant finish to lightweight fabrics such as silk, chiffon, and lace.
- Use a Rolled Hem Foot: Attach a rolled hem foot to your industrial sewing machine. This specialized foot helps to roll the fabric edge under as you sew.
- Set the Machine: Adjust the machine settings for a narrow stitch width and a short stitch length.
- Feed the Fabric: Place the raw edge of the fabric under the rolled hem foot, aligning it with the guide on the foot. Slowly start sewing, allowing the foot to roll the edge under as you go. Keep the fabric moving smoothly and evenly, and use your fingers to guide the fabric gently.
- Finishing: Once you've sewn the entire length of the hem, trim the thread ends.
Troubleshooting Common Issues
Even with a properly set up industrial sewing machine, you may encounter some issues during the hemming process. Here are some common problems and their solutions:
- Skipped Stitches: Skipped stitches can occur if the needle is dull, the thread is too thick for the needle, or the tension is incorrect. Replace the needle with a new one of the appropriate size, use the correct thread for the needle, and adjust the tension as needed.
- Puckering: Puckering can happen when the needle is too large for the fabric, the tension is too tight, or the fabric is not moving smoothly through the machine. Try using a smaller needle, adjusting the tension, and making sure the presser foot pressure is appropriate.
- Thread Breaking: Thread breaking can be caused by a rough or dirty needle, a clogged thread path, or incorrect tension. Clean or replace the needle, check and clean the thread path, and adjust the tension.
Maintenance and Care of Your Industrial Sewing Machine
Proper maintenance and care of your industrial sewing machine are essential to ensure its longevity and optimal performance. Here are some tips:
- Regular Cleaning: Clean your machine regularly to remove dust, lint, and thread scraps. Use a soft brush to clean the bobbin case, feed dogs, and other areas where debris can accumulate.
- Lubrication: Follow the manufacturer's instructions for lubricating your machine. Use the recommended lubricant and apply it to the appropriate parts at the specified intervals.
- Needle Replacement: Replace the needle regularly, especially when it becomes dull or bent. Using a dull needle can cause skipped stitches, thread breakage, and damage to the fabric.
- Storage: Store your machine in a clean, dry place when not in use. Cover it with a dust cover to protect it from dust and moisture.
