How to use Leather Sewing Machines?
Leather is thicker than your average sewing material fabric and needs to be treated in a different manner. Although it is a tough and resistant material, it can easily be ruined by stray holes, markings or scars. There are a few ways that you can make your experience with sewing on leather a little bit less frustrating. One of the most important things to remember when using leather sewing machines is to watch your thread tension very carefully.
Standard sewing machines will automatically try to adapt with a tighter stitch which will cause your thread to break and your leather to perforate. Look at the strength of the needle that a leather sewing machine can accept. Most needles will work for leather as long as the point is razor sharp and the needle is thick enough. A thin needle could end up tearing your material or breaking off completely.
Some sewing machines do not accept synthetic threads and it is always better to use a vertical spool instead of a bobbin when using thicker synthetic thread. The upright spool will allow the thread to run off easily without knotting or snapping. Look for the kind of stitch adjustments available on a leather sewing machine.
On an upper end model this will be a push button feature and a dial command on a lower end model. For leather sewing you will need to use longer stitches rather than short tight ones. This is one of the key factors you will need to look for in a leather sewing machine.
How to Setup a leather Sewing Machine?
Industrial machines set up much differently to standard home machines. Home machine motors are built in to the machine head itself while industrial machine motors are usually mounted to the underside of the table, separate from the machine. To set up your machine follow these easy steps:
- Always read the manual because each machine is different, it is best to familiarize yourself with your machine.
- Locate your machines power switch. It is usually located on the right side of the machine.
- Wind your bobbin by inserting the thread through the hole in your spool. Wind the thread around the bobbin a few times before placing it into place on the small spool. Place your thread on the larger spool and slowly press down on the pedal to make the bobbin wind the thread until it is nearly full
- Once the bobbin is threaded, you can load it into the bobbin case below your needle.
- Thread the top parts of your machine by guiding the thread through the top area and bring it down through the indicated guides to the needle.
- Pull the thread through the needle and pull till it’s taut. Turn the knob on the side of your machine to catch the thread. Your machine is now set up and ready to use.
How often Should a Leather Sewing Needle be Replaced?
A blunt needle will rip and tear through your fabric if it is blunt or dull. The average sew time is plus minus 8 hours depending on the type of sewing you are doing. Sometimes a blunt needle is not the reason for needing a needle change. Sewing over straight pins could cause your needle to bend, kick and even break. Leather sewing needles should be replaced regularly because of the nature of the material.
A blunt needle will cause damage to a heavier leather material and might very well tear the leather instead of cutting through it neatly. Pay attention to your leather sewing machine and you will be able to tell if it is time to change the needle. If your machine is making strange clicking noises it could very well be the result of an old or bent needle. A bent needle could cause burrs which is when your thread frays.
This could weaken your thread and cause it to break when working with heavy fabrics such as leather. Once a hole is made in a piece of leather fabric, it is impossible to fix or close so always test your needle for sharpness on a spare scrap of leather before going ahead on the actual leather project.
How do Computerized Industrial Leather Sewing Machines Work?
Computerized sewing machines are powered by an electronic loop stitching system rather than a manual one. This excellent computer technology is more effective than typical hand stitching and permits the sewing machine to produce an automatic process whereby the industrial needle passes through the fabric. This enables a constant movement to enhance the rate and reliability of the sewing procedure.
After the needle passes through the leather, a loop is produced in the material which ensures proper needlepoint access. Electronic industrial machines are capable of performing a wide variety of different stitches while the presser foot keeps the material in place. Industrial electronic sewing machines are able to produce large sewn items quickly and effortlessly.
Electronic sewing machines can be confusing for beginners because of all of the functions, knobs and levers but keeping your manual on hand should help you sort out any snags you might come across. These types of machines save you time and money in the long run because you can be ready to perform even the most complicated stitches at the touch of a button.
