Over lock m/c
Overlook stitching was invented by the Merrow Machine Company in 1881.An overlook stitch sews over the edge of one or two pieces of cloth for edging, hemming or seaming. Usually an overlook sewing machine will cut the edges of the cloth as they are fed through (such machines are called ‘sergers’), though some are made without cutters. The inclusion of automated cutters allows overlook machines to create finished seams easily and quickly.

Bar tack m/c
Bar tacking is accomplished by sewing a very tight zigzag stitch across the width of the material. In some cases, the manufacturer may go over the bar tacking again, causing the stitch to have an x-like form. Usually, very strong threads are chosen for bar tacking so that they will stand up to high pressure. When done correctly, bar tacking can help support loads of up to 400 pounds (almost 200 kilograms). Many backpacking companies in particular pride themselves on the number of bar tacks integrated into their products, claiming that they will wear harder and longer than the competition
Applications:
Ø To created barack stitches in garments.
Bar tacking is a specialized sewing stitch designed to provide Immense tensile strength to the garment or equipment it is used on. Bar tacking is commonly used on backpacks, tents, tactical gear, and other heavy wear sewn items where normally sewn stitches might give way at a crucial moment. In general, bar tacking is a sign of good quality, although the rest of the product should always be looked over carefully as well. When a sewing pattern calls for bar tacking, it indicates that the designer feels that section of the pattern is a critical area that needs extra reinforcement and following areas it can used.

Chain stitch m/c
Chain stitch is a sewing and embroidery technique in which a series of looped stitches form a chain-like pattern. Chain stitch is an ancient craft - examples of surviving Chinese chain stitch embroidery worked in silk thread have been dated to the Warring States period (5th-3rd century BC). Handmade chain stitch embroidery does not require that the needle pass through more than one layer of fabric. For this reason the stitch is an effective surface embellishment near seams on finished fabric. Because chain stitches can form flowing, curved lines, they are used in many surface embroidery styles that mimic "drawing" in thread
