Normally a plain stitch can be of the four different types such as lockstitch, coverstitch, overlock and chainstitch.
The process of stitching involves various feed mechanisms of the materials. Apart from the movement of the needles, bobbins and rollers, it is essential that the fabric to be woven must move uniformly with the needle so that each round of the needle movement entails to stitch a different part of the clothing material. These movements of the needles are known as feed and there are large numbers of ways in which a needle can be fed to a sewing machine. Some of these general feeding ways include: drop feed, needle feed, puller feed, manual feed and walking foot.
The needle of the sewing machines is specially manufactured in order to suit their respective needs. The needles are chosen according to the type of fabric that is entailed to be woven.
