Next comes the assembly process, where the cut fabric pieces are sewn together. This involves a series of techniques such as pinning, basting, and finally sewing the pieces with a sewing machine or by hand. Each seam must be constructed with care, ensuring that the seams are secure and the garment maintains its shape. Techniques like topstitching and finishing the edges help achieve a polished look, which is essential in high-quality garment production.

The lockstitch sewing machine is an essential piece of equipment in the textile industry, renowned for its efficiency and versatility. Its operation is fundamental to modern garment manufacturing, providing a durable and reliable stitch that is crucial for constructing clothing and other fabric-based products.

Thick threads, often made from polyester, nylon, or waxed cotton, are designed to provide strength and durability. Their impressive tensile strength ensures that the seams can endure the stress and strain that leather items often encounter. Leather, being a robust and flexible material, demands a thread that can match its endurance. Thick threads fulfill this requirement, rendering them particularly suitable for items such as belts, bags, wallets, and shoes.

Cost-effectiveness is another aspect that cannot be overlooked. Although there is an initial investment in purchasing handheld bag closing machines, the long-term savings can be significant. By reducing labor costs and minimizing product waste due to poor seals, businesses can enhance their profit margins. Moreover, many models are energy-efficient, further contributing to operational savings.
