Uses: Automatic Welting Machine (APW) is a specialized sewing machine that is commonly used in garment manufacturing factories to attach a strip of fabric (known as welt) to the edge of a garment, usually for reinforcement or decorative purposes. The process of using APW to manufacture garments in a factory typically involves the following steps:

  • Preparing the garment pieces: Before the welting process begins, the garment pieces are cut and prepared according to the design specifications. The edges of the garment pieces that need to be welted are usually folded and pressed to create a clean and precise edge.
  • Setting up the APW machine: The APW machine is set up according to the specific requirements of the garment being manufactured. The machine is adjusted to the correct tension, stitch length, and stitch type to ensure that the welt is attached to the garment securely and evenly.
  • Feeding the garment pieces into the machine: The garment pieces are fed into the machine, and the edge that needs to be welted is placed under the welting foot. The operator guides the garment pieces through the machine, ensuring that the welt is positioned correctly along the edge of the garment.
  • Sewing the welt onto the garment: The APW machine sews the welt onto the garment edge with a specialized stitch, such as a chain stitch or a lock stitch. The machine automatically cuts the welt to the correct length and sews the ends together to create a continuous strip.
  • Trimming excess fabric: Once the welt is attached, any excess fabric is trimmed away using a cutting blade on the APW machine. This ensures that the finished garment has a clean and neat appearance.
  • Inspecting the finished garment: Finally, the finished garment is inspected to ensure that the welt is securely attached and that there are no loose threads or other defects. If any issues are identified, the garment may be reworked or repaired before being sent for further processing.

Overall, the use of an Automatic Welting Machine (APW) in garment manufacturing allows for a faster and more efficient production process, while also ensuring consistent and high-quality results.

Components: An automatic pocket welting (APW) machine is a specialized industrial sewing machine used for attaching pockets to garments. The APW machine has several components that work together to achieve its function. These components include:

  • Sewing Head: The sewing head is the part of the APW machine that does the actual sewing. It consists of a needle, feed dog, and presser foot. The sewing head moves back and forth to create stitches that attach the pocket to the garment.
  • Pocket Feeder: The pocket feeder is responsible for feeding the pocket material into the sewing head at the correct time and position. It consists of two rollers that pull the pocket material through the machine.
  • Garment Feeder: The garment feeder moves the garment material into position so that the sewing head can attach the pocket to the garment. It consists of a flat surface and a set of rollers that hold and move the garment material.
  • Knife: The knife is used to cut the pocket material to the correct size and shape before it is attached to the garment. The knife is located near the pocket feeder and is operated automatically by the machine.
  • Thread Cutter: The thread cutter is a small device that cuts the thread after the stitching is complete. It is located near the sewing head and is also operated automatically by the machine.
  • Control Panel: The control panel is where the operator sets the machine's parameters, such as stitch length, pocket size, and positioning. The control panel may be digital or analog and may include a touch screen.
  • Servo Motor: The servo motor is the power source for the machine. It provides the energy needed to move the various components and to control the sewing speed.

Overall, the APW machine is a complex piece of equipment that requires specialized knowledge to operate and maintain. Its various components work together to create precise and durable pocket attachments on garments.
