There are several different industrial sewing machine systems. The “walking foot” mechanism is one of the best and most commonly used systems for feeding manifold layers of dense, slippery or thick material, including leather. An Industrial Walking Foot Sewing Machine can accurately sew layers of fabric without slipping or crumpling of seams. It is ideal for denim, canvas, upholstery, leather and vinyl sewing trades.
How a Walking Foot Machine Works
While there are several varieties of the walking foot feed mechanisms, the triple feed system or compound feed system is the most common one. A triple-feed sewing machine has two alternating presser feet: the bottom feed dog and the inside presser feet. The feet move the fabric by synchronizing the needle or the bar’s motion. While the fabric is being moved, the outer foot is raised off the work. This enables the needle, the feed dog, and the inside foot to convey easily all of the fabric layers together till the preset stitch length is attained.
Once the preset stitch length is reached, the outside foot drops under spring pressure to hold the work. Then the needle starts to ascend; forming a thread loop, which goes around the bobbin before fully withdrawing from the fabric. The outer foot holds on firmly on the fabric as the needle bar and the inner presser foot move into position for subsequent stitches.
With the triple feed mechanism, heavy, dense, slippery or manifold layered material can neither drag nor get out of alignment. The stitch length remains consistent, from stitch to stitch. Lastly, the lowered outer presser foot prevents the work from moving till you decide to – by raising the feet through the knee lever or the hand lifter.
Advantages of Using Walking Foot Machine
Higher Foot Lift
This is especially advantageous when you are sewing very thick fabrics. Just being able to pass that extra 1 – 2mm of fabric under the presser foot may be a great relief.
The Built-In Walking Foot
The actual built-in walking foot is the greatest advantage of a walking foot sewing machine, as compared to the regular household machine. The built-in walking foot steadily feeds your fabric as it pulls the fabric from the bottom. It coordinates with the feed dogs that pull the bottom of the fabric for dual uniform feeding.
A Mini Full-Size Industrial Sewing Machine
A walking foot sewing machine is like a mini full-size industrial sewing machine. The motor is normally fixed at the back-end of the sewing machine. This allows moving the machine anywhere you desire around your home or business.
Many sailors, for instance, take their machine with them on their boat. You can simply grab your sewing machine from the middle housing and carry it with you. You should expect a little straining as the machine weighs about 35 pounds.
Generally, walking foot machines are very durable. While they are made of cast iron, all the parts are entirely metallic. The parts will serve you for many years to come. It is imperative that you always buy genuine, heavy duty parts.
The Industrial walking foot sewing machine is among the hidden gems in the world of sewing machines. The industrial strength mechanisms can manoeuvre through numerous layers of thick material. Through the years, these machines have also become affordable, which is a win-win situation for businesses as well as sewing machine enthusiasts across the world.
