double needles chain stitch sewing machine

Invented by Elias Howe in 1846, the single lockstitch machine was the first successful sewing machine design, predating the more familiar Singer model. It operates on a principle that involves two threads - one from the needle and another from the bobbin - interlocking to create a secure stitch. The needle thread passes through the fabric, forming a loop, which the bobbin thread then catches, creating the characteristic 'lock' in the stitch. This process not only speeds up sewing but also ensures durability and strength in the final product.

What is a Zigzag Sewing Machine?

Single heavy duty sewing machines are incredibly versatile. They come with various stitch options, from basic straight and zigzag stitches to more complex decorative stitches. This flexibility allows users to complete a wide range of projects, including garments, home décor, and crafts. Whether you’re sewing a thick leather handbag or creating a quilt with multiple layers, a heavy duty machine can handle the job without requiring additional adjustments or special attachments.

Heavy-Duty Sewing Machines: Maintenance routines for these machines are more frequent than industrial ones but less intensive. Regular cleaning, occasional oiling, and timely servicing should suffice.

An auto oil sewing machine, as the name suggests, is designed with an automatic oiling system. This feature not only ensures optimal performance but also prolongs the lifespan of the machine by lubricating its moving parts consistently and efficiently. Unlike traditional sewing machines that require manual oiling, which can be time-consuming and often overlooked, the auto oil system operates seamlessly, reducing the risk of wear and tear and potential breakdowns.

1. Needles Use heavy-duty sewing machine needles (size 14/90 or larger) which are designed to penetrate thick fabrics without bending or breaking. Universal needles can also be effective for sewing medium-weight canvas.
