Subtleties of choosing an industrial overcasting machine

Before approaching the selection of a brand and a selected overlock model, it's necessary to work out the category of the overcasting machine. during this regard, all overlocks are divided by the amount of threads participating within the process of seam formation, which entails structural differences. Such a division, of course, didn't develop yesterday but was the results of an extended development of design ideas within the development of stitching equipment with regard to the technology of tailoring certain textile products. Three-thread models – overlocks that perform a three-thread sewing seam, formed by one needle thread and two threads from the upper and lower loopers. These overcasting machines are used for overcasting sections of materials susceptible to shedding. As a rule, these are various woven fabrics. Three-thread overlocks are primarily purchased and used at large sewing enterprises, where re-adjustment of overlocks with an outsized number of threads to a three-thread isn't economically feasible. there's also a separate modification of three-thread overlocks for performing a task seam, also called hemming or optic.
