Shoe Stitching Machine Working Principle

Shoe assembling is a crucial stage in the shoe-making process that assists in the joining of shoe parts to achieve the ultimate shoe form. At BSM India, we produce the best shoe-making machines that can stitch shoes with a lot of efficiency as compared to manual stitching. In this blog, we will also discuss the working of a shoe stitching machine along with their components, characteristics, and working principles.

Shoe Machines – Components

A shoe stitching machine can be described as an assembly line comprising several components that are used to stitch shoe parts. The main components include:

• Stitching Heads: Sewing needles as the components of stitching heads, which move up and down to connect stitch shoe materials. Stitching heads can be single or multiple to stitch different parts of shoes as required.
• Throat Plate: This is a metal plate through which the shoe materials pass as they undergo stitching. It offers a flat platform on which the fabric can rest.
• Presser Foot: The presser foot is used to press the shoe components in place as the needle sews through them. They avoid aggregation and provide clean, straight sew lines.
• Feed Mechanism: Feed mechanisms advance the shoe component automatically at a predetermined rate in collaboration with the stitching heads to produce uniform stitches. Some of the most frequently used types include bottom feed, alternating feet feed, and many more.
• Work Clamps: Stitching work clamps have an excellent clamp that ensures that the shoe components are well fixed in position under the stitching heads. This prevents movement and deformation when stitching the different parts of the garment.

Principal Elements of Shoe Stitching Machines

Some useful features of our shoe-stitching machines include –

• Programmable Stitch Length: Stitch length can be programmed and manipulated for different shoe parts according to the need for stitching.
• Automatic Trimmer: There are cutting blades mounted in the machines which when stitching, cut off the end of the threads to complete the neat stitching look.
• Easy Stitch Width Adjustment: Stitch width can be easily regulated for creating different stitches such as zigzag stitch, double chain stitch, etc.
• Safety Guards: Guards are fixed on dangerous operating parts to minimize the chances of the operator getting close and getting injured.
• Production Display: A large LED/LCD has counters to produced pieces and daily production rate for the monitoring of production rate.

Importance of Shoe Manufacturing Machines

The shoe stitching process with automatic machines means that there are sequence of operations where the different parts move in harmony to bring the stitch threads and interlock them in the shoe pieces. The main steps are:

• Feeding Shoe Components: Shoe upper components or sole pieces are manually or automatically conveyed to the entry or receiving area. It correctly positions guide arms under the stitching heads.
• Clamping Components: Other clamps hold the positioned parts firmly and securely in place in order not to be displaced during the operation of the machines.
• Initial Piercing of Needles: The stitching head needles first penetrate through the layers of the shoe supported by clamps and presser foot. This produces the first opportunity for stitches to occur.
• Interlacing Stitch Formation: The needles vibrate up and down at a high speed while the feed mechanism translates the clamped part at a slower rate. This synchronizes to interlock the needle threads into the shoe layers by passing from one side to another in a looping fashion.
• Binding and Tightening: The stitches create tight neat seams that enable secure joinery of shoe parts because the needle penetration is shallow and the threads tightly interlock.
• Trimming Thread Ends: Trimming blades mounted on each of these rollers trim off any loose threads near the stitching zone as part of getting a neat finish.
• Releasing Stitched Component: It is only when the clamps have released the stitched shoe component that the finished stitched pieces can be removed.
• Automated Control System: The complete movement of several parts of the machines is done by electrical systems and controllers which are programable to enable real-time control.

Benefits of Shoe Stitching Machine

• Speed and Efficiency: The main benefit of the shoe-making machines is that it enables faster stitching and higher productivity as compared to manual stitching. These computerized machines can sew at a rate of about 3000-4000 stitches per minute. This is doable in a shorter time than what a manual cobbler would be able to accomplish. The programmable settings also allow for stitch length and stitch pattern adjustments as well. 
• Consistency and Accuracy: The other advantage of using machines is that they offer increased and precise levels of stitchings. They are designed and constructed in such a way that they offer precise stitching and are accurate. There is little variation in stitch length or the line that the stitch runs in. This results in neat and powerful seams that could not be achieved by hand work due to high precision.
• Quality and Durability: The quality of stitching that is done by a shoe stitching machine is better and more long-lasting since the process is programmed. The even tension and pattern of interlinkage to form the seams offer the best shot for holding up during wear and tear. Other features such as heat settings and its back-tacking functionality make the stitching superior to a manual process.
• Customization Ability: One of the benefits of using computerized shoe making machines is that programmers can set parameters such as stitch type, density, or pattern. This enables customization depending on the various shoe parts, materials, or designs
• Increased Production Volumes: Shoe producers, for instance, can increase their production rate drastically because the once lengthy process of stitching is made quicker by the mechanical power supplied by the machines.  as required.
