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.
